MEMThe Satellite Shambles
WMr
Amami
Tragedy, farce or just plain bungling? The start of satellite TV broadcasting in the UKshould have been a moment of triumph, the start of a new era in TV, leading to newprospects such as high -definition television. Instead, just look what's happened. Amakeshift start with almost no receiving equipment in the shops and unedifyingbickering between those who will be providing the services, Sky and BSB.
One cannot help but admire the drive that has gone into getting Sky started in amatter of months. It has been almost like the pioneenng initiatives that accompanied thestart of the BBC's first service in 1936. There are other parallels. First almost no directviewers - not all that many more than in 1936, though perhaps a few thousand ratherthan a few hundred. And secondly we have the perennial standards problems all overagain.
It's a far cry from the careful planning that has gone into the extension of TV servicesover the last few years. Channel 4 for example came in beautifully on cue and after thenovelty of the first night one might have been forgiven for thinking it has been there allthe time. Teletext was introduced with no fuss and few problems, and soon thoseinclined to do so were busy with their remote control buttons. All different this time.There's confusion amongst viewers, in the press and in the trade, and just where are allthose dishes we had been promised? Well, no one is going to go overboard producingnew equipment for a new, untried market, but that apart there seems to have been aproblem resulting from Sky's ad hoc approach to getting its services started. Thechannels were all to be unscrambled originally, financed by advertising. But then theowners of the film rights, the main attraction offered by the new services, cottoned on tothe fact that much of Europe would also be able to see the movies, and Mr. Murdochhadn't paid for that. To get over the problem, a hasty decision was taken to adoptscrambling. And that of course affected the design and production of the receivers,especially as it took a time to decide on the form of encryption to use. Presumably thedelays are a temporary matter and we shall soon see the High Streets awash with dishes.Maybe.
This sad start reflects the brief history of attempts to get DBS started in the UK.There was one false start after another. Originally the BBC, in early 1982, was given thego-ahead to start a two -channel service, hopefully in 1986. In the following year, 1983,the IBA was authorised to supervise a commercial service. By mid -1984 the BBC, underthe usual financial pressure, abandoned its attempt. A consortium that included theBBC, the fifteen ITV companies and others then had a go. By June 1985 the consortiumhad given up, reporting to the government that the project would not be commerciallyviable under the conditions laid down. There followed a year when little happened, andthen in mid -1986 the IBA was asked to try to start a service. This time there wasconsiderably more interest and several strong groups competed for the franchise. It wasawarded to BSB in December 1986.
BSB's planning has been meticulous, as you might expect of an organisation operatingunder the guidance of the IBA. It has undertaken a lot - to commission and launch itsown satellite system and to guarantee services to standards accepted as part of thefranchise. The cost has been huge. Exact figures are not available, but informed guessessuggest that over £800 million is being invested in the project. What it didn't plan for wasthe appearance of Sky on the scene, via the medium -power Luxembourg Astra satellite.
Despite having got there first, Sky has its problems - not only the shortage of dishes.The main problem will be to finance the service until the advertising revenue starts tocome in. It's a classic chicken -and -egg situation. No viewers, no advertising revenue; noadvertising revenue, no income to splash out on programmes to attract viewers. Theschedules so far made available by Sky suggest that second-hand sit-comm, soaps etc.will comprise much of the fare. It's not inspiring to say the least, but what can youexpect? Sky doesn't have the funds that say the ITV companies are used to.
The unfortunate aspect of the Sky intervention is that it could end up jeopardising thewhole satellite scene in the UK and with it the prospects for further technical progress,programme options and business opportunities. It's questionable whether there is roomfor one DBS service in addition to the present terrestrial services, but we are to start offwith two providing some eight channels between them. Dicey indeed. Especially whenyou consider what the viewer is being offered. BSB is to charge about £10 a month forits film channel while Sky will be asking £12 a month for its scrambled channels. About£120 and £144 a year respectively compared to the present colour licence fee of £62.50.Hardly a bargain, on these terms alone, regardless of the extra equipment required. Andthis brings us to the duplication required for both BSB and Sky. The TV systems aren'tthe same, the encryption systems are entirely different and whereas BSB has conditionalaccess Sky is to rely on a smart card. How many little boxes does that add up to?
To have made the most of the opportunities presented by satellite broadcasting acollaborative effort by all concerned would have been best, to plan carefully, prepareviewers and then start up the new services with the smoothness we had come to expect.But that sort of thing hardly goes with the new era of deregulated broadcasting. Insteadwe have had to watch Sky and BSB engage in public dispute that's purely counter-productive. It does not augur well for the future of broadcasting in the UK.

TeletopicsMULTI -SATELLITE RECEIVING SYSTEMMicro -X has become sole distributor in the UK of theMapro STVS satellite TV receiving system. Since thesystem is upgradable to provide dish tracking and hasinfinitely variable polarity selection it can be used forreception of all the available and proposed satellitesincluding Astra, the BSB craft and the Eutelsat andIntelsat series satellites. The basic price is £299 which with£60 for installation brings the total to £359: to add fulltracking takes the total cost of an installation to £584.These figures do not include the cost of decoders toprovide unscrambling of course. It's certainly a high -quality system with its steel dish, ferrite polariser andHEM (high electron mobility) transistor LNB. The latterhas a noise figure of 1-6dB. Mapro systems are being soldthrough Micro -X's network of dealers - Micro -X can bereached on 01-459 1200.
THINNER VHS TAPEJVC has developed thinner video tape to extend theplaying time with S -VHS -C and VHS -C equipment. Theseformats at present have a maximum record/playback timeof thirty minutes in standard play and an hour in long play(for 625 -line signals). Current VHS -C tape is 19 micronsthick, consisting of a 5 micron magnetic layer, a 13 micronbase film and a 1 micron backcoating. The new tape has a4.5 micron magnetic layer and a 10 micron base made of anew material called Polystone. This increases the playingtime to 45 minutes (SP) and 90 minutes (LP). Accordingto JVC a new high -stiffness binder ensures high tapedurability. No price or launch dates have been announcedso far.
SATELLITE TV LATESTSky Television has reduced its estimate of the number ofhomes likely to be able to receive its transmissions afterthe first year of operation from 2.5 million to 1.15 million.A total of around 2.5m is considered to be still achievable,but the guarantee figure for advertisers is now 1.15m. Onthe advertising sales side Sky intends to undercut ITVrates by some 25 per cent. Free repeats will be offered ifaudiences fall below the guaranteed figure. Advertisingagency Saatchi and Saatchi estimates that a total ofaround 420,000 receiving systems for Sky and BSB willhave been installed by the end of the year. At presentthere appears to be a shortage of equipment, possiblybecause manufacturers are reluctant to increase produc-tion until the orders start to flow in.
The Thorn -EMI rental division (DER, Radio Rentals,MultiBroadcast and Focus) reports a high level of interestand has ordered over 40,000 receivers from Grundig.These will sell at around £349 with remote control.Granada is buying equipment from Salora and Tatung.
BSB has awarded a £50m contract to operate itscustomer management and advisory service to BritishSatellite Systems, a joint venture company formed byNext plc and CableData Inc of California. The CustomerService Centre will be at the Arlington Business Centre,Leeds and will initially create 400 new jobs in the city. Itwill handle the enablement of all BSB receivers, willanswer viewer enquiries about equipment and program-
ming and will handle the administration of subscriptionsfor the BSB Movie Channel and pay -per -view events.Information will be transferred from the Centre to Next'smainframe computer in Bradford then to BSB's comput-ers at its Earth station at Chilworth near Southampton.Each BSB receiver will have a unique number, making itindividually addressable over the air so that it can beturned on via the satellite.
Super Channel was saved from bankruptcy when credi-tors accepted a plan which will mean they are paid only aquarter of the £8m they are owed. New owners BetaTelevision hope that the channel will now break even witha new programming arrangement consisting mainly ofmusic.
RTEEB 1988 VIDEO AWARDSteven Gerald Thomas has received an award of £100after achieving a 100 per cent pass mark in the Radio,Television and Electronics Examination Board's 1988video recording and playback practical test. Steven is 31and lives at Wirral. He's been in the trade for twelve yearsand is at present employed by Servicescope. This is thefirst time that anyone has obtained a 100 per cent passmark. Course tutor was none other than Joe Cieszynski,who writes regularly in Television.
FAULT GUIDESBoth JVC and Sony have recently published fault guidehandbooks, adopting a similar approach with a page toeach fault.
The Sony Service Fault Finding Guide Edition 2 isintended as a supplement to Sony's first three guides
no. S-795-100-01), TV (S-796-000-01) and video (S-796-202-01). A page is devoted to each fault symptom and theprice is still £4.95 per volume. The new Guide coversmore recent Sony models of all types, including CDplayers, 8mm equipment, TV sets etc. Its part no. is S-795-015-10 and the price is £7.95. These publications canbe obtained from Regional Sony Service Centres, SESLtd. or (account holders only) from the Sony Spare PartsDepartment at Thatcham.
The JVC Fault Diagnosis Guide Vol. 1, covering VCRsand camcorders, has a similar format but in additionincludes check points for each fault, a useful addition.Some 200 faults from the obvious to the obscure arecovered. The Guide is available from JVC (UK) Ltd. at£10.80. Write to JVC House, Eldonwall Trading Estate,Priestley Way, London NW2 7BA or 1 Olympia IndustrialEstate, Gelderd Road, Leeds 12.
S -VHS -C CAMCORDER WITH HI -H SOUNDJVC has release) details of the first S -VHS -C camcorderto feature hi-fi sound recording. Model GR-S707U has astandard size (62mm) drum instead of the usual 41.3mmdrum. This has been made possible by incorporating thedirect -drive motor inside the drum itself. The GR-S707Uweighs only 1.7kg: its body has been redesigned so that itrests on the shoulder for normal shooting.
Other features include a 360,000 pixel CCD imagesensor with 8 -lux sensitivity, two -speed x 8 power zoom, amultiple speed fast shutter, time-lapse recording, anima-tion recording, VHS indexing, variable speed search,noiseless still and slow-motion playback, auto/manual irisand white balance, backlight compensator, a stereo micro-phone, HQ specification, insert editing, audio dub, S-

video/AV sockets and optional remote control. It will belaunched in NTSC countries later this year - there are nodetails yet of a European launch.
INTERACTIVE TV SYSTEMA recent issue of the US magazine Radio -Electronics(December 1988) contained details of a proposedinteractive TV system to enable viewers to participate inTV game shows. It's called IGN (interactive games net-work) and makes use of computer technology, an f.m.subcarrier and TV sets. Those participating would use aninteractive games console which is linked to a controlcomputer in the studio via a telephone modem andreceives instructions on answering via a transmitted f.m.subcarrier. The system apparently meets FCC regulations.
VHS PENETRATIONJVC has released details of the growth and developmentof the VHS system. By the end of 1988 cumulativeshipments of VHS equipment worldwide had reachedsome 210 million VCRs and 11.2 million camcorders. Inthe same year blank tape sales were estimated at onebillion units with prerecorded software accounting for afurther 190 billion units. JVC points out that 60 per centof the VCR shipments have taken place during the pastthree years. The format was launched in Japan in theautumn of 1976. A million VCRs had been shipped by1978, when VHS was launched in Europe. The ten millionmark was reached in 1981 and the 100 million mark in1986.
The regional breakdown is as follows: Europe 45million VHS VCRs (21.4 per cent of the total); NorthAmerica 96.6 million (46 per cent); Japan 37 million (17.6
per cent); other areas (including the Middle East, Aus-tralasia and South America) 31.6 million (15 per cent).VCR household penetration is estimated as UK 60 percent, Japan 70 per cent, USA 60 per cent, West Germany40 per cent and France 30 per cent. The camcorder figuresare UK 1 per cent, Japan 8 per cent, USA 6 per cent,West Germany 3 per cent and France 1 per cent.
In NTSC areas S -VHS now accounts for some 20 percent of total VHS sales. JVC expects European S -VHSsales to reach 15 per cent this year with an annual growthof 10 per cent thereafter.
IN BRIEFThe Cable Authority is to review all franchises that havebeen awarded for over a year and intends to cancel anythat seem to be dormant. No work has been done yet ontwo of the original franchises awarded in November 1983- in Belfast and Liverpool. Several other franchisesappear to be stalled . . . Tatung is to install a new £4.6mproduction line in the UK with a capacity to produce100,000 monitors a year The existing colour TV receivermanufacturing facility is also being expanded . . . SixteenUS electronics companies have formed a partnership todevelop an HDTV system and facilities to produce HDTVequipment. The American Electronics Association hasbeen campaigning for such a move for some time and ishoping to obtain government funding for the research anddevelopment required . . .

Failure and SuccessLes Lawry -Johns
I seem to be giving up more often when confronted withfaults I could put right without thinking about it a coupleof years ago. Take the Fidelity CTV14R that came in theother day. The rear -mounted 18kfl wirewound resistorthat feeds the 12V zener diode ZD5 was open -circuit so Ireplaced it. Switching on brought no response however.There was h.t. at the collector of the chopper transistorbut it wasn't being switched on. I checked the drivertransistor and all the components associated with theTDA2581 control chip, including ZD5. A couple of itemsdidn't read right: I replaced these but the set still didn'twork. So I gave up and admitted defeat.
Then look what happened just before Christmas. Awoman brought in an ex -rental Multibroadcast set forrepair. I told her I'd phone when I'd found out what waswrong. It turned out to be fitted with the Thorn 9000chassis. The tripler and a couple of other things had gone,par for the course with these sets. I phoned her and gaveher an estimate for thirty pounds. At this she said mostemphatically that she didn't want the set done becauseshe'd paid only seventy pounds for it about two yearspreviously and had had to spend money on its since. She
told me not to do it and the set stayed in the shop into thenew year.
Honey Bunch started to moan about the sets that hadbeen left with us. Said they were cluttering up the shop.So when this chap came in and asked if we wantedanything dumped I pointed to the front row and he tookthem away. This included the Multibroadcast set. Severalweeks later a chap came in and asked to collect it. I toldhim it had been dumped and told him he could takeanother working set in exchange for it. He took a nice20in. Ferguson model and I didn't hear any more for aweek or so. Then the woman phoned to say that shewanted her Multibroadcast set back. I told her it had beendisposed of as she hadn't wanted it done and I couldn'tkeep sets that weren't collected. She said she'd sue meunless I could produce an identical set. I'm still waitingand the threat has been repeated. Oh dear!
I do have the occasional success however, sometimesafter a struggle. Take the Philips G11 that came inrecently. I repaired the line output panel and thought thatwas that. It wasn't. The picture was dark and the bright-ness control had no effect. Checks showed that there wasa short from one end of R6065 to chassis until plug 6C wasremoved. This led me to the power supply panel wherezener diode D4090 (BZX79-C4V7) in the beam limitercircuit had gone short-circuit. Fitting a replacement pro-duced a good picture with full control. I'm still waiting forthe set to be collected . . .
Book ReviewsAn Introduction to Satellite Television, new edition, byF.A. Wilson, published by Bernard Babini (publishing)Ltd., The Grampians, Shepherds Bush Road, London W67NF at £5.95.Such is the interest in satellite TV that a new extendedand updated edition of this book, which first becameavailable early last year, has now been published. It's auseful handbook for any technician thrown in at the deepend by the coming of Astra and BSB, beginning with thebasics and ending with the maths. Its prime virtue is that itdeals with today's requirements in the UK - so manyrecent books have been written mostly with the C bandused in the Americas in mind. H.P.
Getting the Most from your Multimeter by R.A. Penfold,published by Bernard Babani (publishing) Ltd., TheGrampians, Shepherds Bush Road, London W6 7NF at£2.95.Electronics changes so fast that the basics tend to beignored - with test equipment meters are neglected infavour of more sophisticated gear. A good multimeter willhowever usually tell you just about all you need to knowabout a circuit, provided you use the right sort and applyit correctly. This book shows you how. H.P.
Newnes Guide to TV and Video Technology by EugeneTrundle, published by Heinemann Professional Publishing,Halley Court, Jordan Hill, Oxford OX2 8EJ. Paperbackedition £8.95.This book is a successor to two well-known NewnesGuides - to colour television and VCRs. The materialfrom the earlier books has been revised, updated andadded to for this single -volume presentation. Its well over
400 pages contain a great deal of basic information ontelevision and video including such up-to-date subjects asMAC encoding, satellite TV reception and S -VHS. Thebook is not intended for those well versed in thesematters, but can be recommended as an easy to followintroduction for those new to these subjects. A carefulstudy will provide a good grounding in TV receiver andVCR operation in fair depth, and the book will afterwardsserve as a handy reference. It can be obtained by post atan inclusive price (in the UK) of £9.95 from Paul RichardsBooks, 28 Boscobel Road North, St. Leonards on Sea, E.Sussex TN38 ONZ. J.A.R.
More Advanced Power Supply Projects by R.A. Penfold,published by Bernard Babani (publishing) Ltd., TheGrampians, Shepherds Bush Road, London W6 7NF at£2.95.This sequel to "Power Supply Projects" is really intendedfor the enthusiast. Because it features modern regulatorchips however it's a handy book to have around. Parti-cularly useful if you have a power supply problem with anolder piece of equipment and decide to replace the wholething with one of the current three-legged devices. H.P.

Servicing Compact Disc PlayersPart 1
One problem with a series such as this is that readers willhave different levels of both knowledge and experience ofthe subject. Thus there's a danger of either boring thosewho have serviced compact -disc players and have at-tended manufacturers' servicing courses or on the otherhand blowing the minds of those who have had little to dowith them. From my experience however I find that mostengineers who have attended short courses on CD playersfind it difficult to commit to memory the theoreticalaspects of the CD system and concentrate more on takingdown notes on stock faults with the player in question.This is not a bad thing of course, and does give theengineer struggling to keep abreast of the latest technol-ogy a degree of confidence and competence when he'sfaced with a player back at the workshop. As for theforgotten theory, you might question whether it's nec-essary. But if you don't consider it necessary to under-stand the theory of how the equipment you meet everyday works you wouldn't buy and read a magazine such asthis! It's possible to deal with a great many faults withoutfully understanding how the system works. What aboutthe difficult faults? Does a knowledge of the theory thenmake a lot of difference? It's a difficult thing to prove, butI personally believe that it does. So we'll begin at thebeginning, and I hope that even the more experiencedamongst you will find that some of the points you missedduring the courses start to make more sense the secondtime round. We'll be including plenty of practical hintsand fault-finding procedures as we go along.
In starting at the beginning the first thing to make clearis just what it is that the player recovers from the shinypiece of plastic we call the disc. This knowledge is vital foran understanding of some of the track skipping andjumping faults that regularly occur with CD players.
Disc Basics
The disc contains up to sixty minutes of left and rightaudio information in the form of 14 -bit words. In additionto the audio data over 200Mbits of data is added to enablethe decoder to carry out error correction and the controlmicrocomputer to operate the front display. In total atypical sixty -minute disc contains over 15,500Mbits ofinformation, in other words fifteen and a half thousandmillion noughts and ones are mechanically stamped on tothe disc. These noughts and ones take the form of pits andland, with a reflective aluminium covering. To play thedisc the beam from a gallium arsenide laser is focused onthe reflective layer, the reflected beam being picked up byphotodiodes. A pit reduces the intensity of the lightreaching the photodiodes whose output, after electronicprocessing, consists of the binary ones and noughts re-corded on the disc.
The data on the disc is laid down as a spiral track that
Joe Cieszynski
starts at the centre of the disc. During playback the laserscans the track at a constant velocity of 1.2m/sec, whichmeans that the disc must rotate faster when the laser isnear the centre than it does when the laser is at the outeredge. This method of scanning is known as constant linearvelocity (CLV) scanning, which is the opposite of theconstant angular velocity (CAV) technique used withtraditional audio disc systems.
Fig. 1 shows the arrangement of the track on the disc. Itconsists of pits and land of varying length, the lengthdepending on the data it represents. Fig. 2 illustrates this.Logic one is represented by an excursion from land to pitor pit to land, logic zero being represented by the absenceof an excursion, i.e. for zero the disc acts as a plainmirror. It can be argued that zeros are not in fact stampedon the disc but are added by the player during the signaldecoding process. We'll be going into this later on.
Disc Production
The important factors in disc production are that everypit is accurately stamped in and that the surroundingsurface (the land) is flat and even. When you consider thatthe pits are 0.6µ wide, 0.11µm deep and as little as0.85µm long you will appreciate the degree of accuracyrequired. Fig. 3 shows how a section of track wouldappear when seen through an electron microscope.

When a recording is made the audio signal is firstconverted into a digital stream. The other data required isthen added. This encoding process is highly complex andwill be covered in detail later. The data is recorded on amaster disc which is used to produce stampers which arein turn used to make the discs supplied to consumers. Thecomplete process, illustrated in Fig. 4, is as follows. (1) Aglass plate is smoothed and polished. (2) A photo -resistlayer is applied. (3) The recording laser is focused on thephoto -resist layer. Its beam is modulated by the digitalstream. (4) After development, pits are present in thedisc's surface. These pits are 0.11µm deep and, as wehave already noted, the transitions from land to pit and pitto land represent the ones in the data stream. (5) Thesurface is coated with silver to protect the vital pit edges.(6) Nickel is applied to the glass master to produce ametal master. (7) The metal and glass masters are sepa-rated. (8) Mother plates are made from the metal masterby stamping. (9) The mother plates are used to makestampers. These are a "negative" of the final disc. (10)The stampers are used to mass produce the final discs.(11) A layer of aluminium is vaporised on to the finaldisc to form the reflective surface on which the CDplayer's laser will be focused. (12) A thin, non -transparentprotective film is added. This also acts as the contentslabel.
Note that the CD player's laser scans the disc from thetransparent side. As a result, so far as the laser isconcerned the pits are actually above the surface (see Fig.2). In other words when the data is read the pits arehigher than the surrounding land.
The precise minimum pit length is 0.833µ,m and themaximum length is 3-05µm. We'll consider the factorsthat determine this format, but first we must understandthe way in which the laser scans the disc.
Scanning the DiscWhen the laser's light is focused on the land part of the
disc the reflected light focused on the photodiodes pro-duces a positive output voltage. The pit height of 0.11µmis about a quarter of the wavelength of the laser light.When the laser beam crosses a pit - see Fig. 5 - part ofit strikes the pit while the rest strikes the surroundingland. The simplest explanation of the result of this is tosay that the light reflected from the pit is 180° out of phasewith that reflected from the land, so that cancellationoccurs. In reality the way in which this cancellation takesplace is far more complex, but as long as we appreciatethat cancellation does occur this is of no consequence. Thedegree of cancellation depends on the land/pit reflectionratio. Calculation shows that with a pit width of 0.6Atmand a focused laser beam (spot) diameter of 1.7/.4m morelight will always be reflected from the land than from thepits - Fig. 5(a) shows this. If this was not the case andthere was no output whatsoever from the laser pickup asthe spot travelled over a pit there would be no signal,which would play havoc with the focus and trackingservos.
When the spot is focused on land area - Fig 5(b) -maximum reflection occurs and the pickup produces ahigh output voltage. As the spot begins to pass over a pit- Fig. 5(c) - there's a reduction in the reflected lightand when the spot is over a pit - Fig. 5(d) - thereflected light falls to a minimum level. Fig. 5(e) showsthe resultant pickup waveform. Notice that the rate of theslopes between the pits and land is constant. Thus the

Minimum Pit LengthThe minimum pit length is determined by the laser's
resolution. At the reflective surface the spot diameter is1.7µm. If the pits were shorter than the beam radius,

more than one pit could be covered by the spot and thetransition between adjacent ones would be missed - seeFig. 6. As a general rule pit length should be equal to atleast the radius of the laser spot. The length of 0.85µmspecified for a compact disc is just in excess of this.
A second factor that governs the pit arrangement onthe disc is that two adjacent logic ones must not bepermitted in the data stream. If this was allowed to occurthe frequency of the light fluctations would be above theresolution of present-day domestic lasers. When we lookat encoding later we'll see that there are other reasonswhy the data must not have adjacent ones, and that inpractice there must be at least two zeros separating twoones.
Minimum pit length can be found from: length of onebit = disc rotation speed/data rate. For a compact disc thisis 1.2m/sec divided by 4.3218MHz = 0.27766µm. Withtwo zeros between ones the pit length must be at leastthree bits long (see Fig. 7). Thus one pit length = 3 x0.27766pm = 0.833pm minimum.
Maximum Pit LengthWhat about maximum pit (or land) length? We've just
seen that there must be at least two zeros between ones.The question we now have is "what is the maximum

number of zeros that can be present between any twoones?". The answer is ten. The pit rate generates afrequency component that's used as a reference by thetracking servo. We shall see later in this series that astream of more than ten consecutive zeros would makethe laser go off track. When we come to discuss theencoding process we'll see that there are other reasons forlimiting the data to ten consecutive zeros. The maximumpit length is thus ten logic zeros plus a logic one multipliedby the length of one bit, i.e. 11 x 0.277pm = 3.05p.m.
Binary Code
There are nine different pit lengths between 3 x0.2774m and 11 x 0.277µm. Each one indicates a dif-ferent set of binary numbers, and we shall see later thatthese numbers form 14 -bit binary words, each separatedby three merging bits.
Reading the DiscFig. 8 provides an overall view of how the disc is read.
A shows a stream of data representing a portion of audiosignal. This is stamped on the disc as shown at B. Whenthe disc is played, the voltage derived from the pickupdiodes is as shown at C. This signal is passed through asquaring amplifier to give the signal shown at D. This isthen fed to the decoder where it's checked against a4.3218MHz clock signal (E) generated in the decoder.Signal transitions are thus detected. On detection of atransition the decoder provides a logic one output: whenthere is no coincidence between a clock and signal transi-tion the decoder's output is logic zero. As mentionedearlier, the zeros are not actually put on to the disc but areadded by the player. The original data is thus recovered(F) and is checked by the decoder to determine what isaudio data, what is error correction data and what is LCDdisplay data. Once it has been separated, the audio data ischecked for errors, decoded and finally converted back toanalogue form.

Introduction to S -VHSUnless you've been on holiday in Outer Mongolia for thepast eighteen months you can't have failed to have noticedthe coming of S -VHS. It's now with us in practical form.We saw it first with the Pansonic NV-MS1 camcorder.More recently the NV-FS1 VCR, on which the practicalaspects of this article are based, has come along. SteveBeeching wrote about the basic S -VHS specification in theJuly 1987 issue - we'll recap briefly on some of this. Let'sfirst look at the improvements over the basic VHS systemand the way in which they are achieved.
As we all know, the horizontal resolution of the basicVHS system is in the region of 240 lines. Thus therecorded picture is noticeably lacking in definition withrespect to the original scene. To the average viewer this isno great hardship - they often tolerate poorly focusedpictures with a poor grey scale. It can be most annoying todiscerning viewers however, particularly those with cam-eras capable of a resolution performance of over 400 lines.S -VHS provides considerable improvement, with a speci-fied horizontal resolution of some 400 plus lines. This isachieved by increasing the f.m. carrier frequency so that agreater luminance bandwidth is recorded on the tape. Thef.m. carrier deviation is 5.4-7MHz compared to 3-8-4.8MHz with standard VHS. The wider deviation of1.6MHz instead of 1MHz improves the signal-to-noiseratio. Increased resolution/bandwidth will increase thenoise level: the wider frequency deviation counteractsthis. Noise is further reduced by employing a non-linearsub -emphasis system which varies the emphasis applied inproportion to the amplitude of the signal being recorded.
Fig. 1 compares the VHS and S -VHS signal spectra.Notice that with the S -VHS system the chrominance andluminance signal bandwidths do not overlap. This animportant feature of the new system since it means thatcross -colour effects can be eliminated as far as recordingand playback are concerned. To take full advantage ofthis the signals have to be kept separate, i.e. fed to thereceiver/monitor as baseband signals instead of being PALencoded, modulated on to a u.h.f. carrier and fed into areceiver via its aerial socket.
All in all the pictures are sharper and better contrasted,with minimal noise. Particular improvement can be seenon edges - such as door frames and the brick/stone detailof buildings.
S -VHS Tape and HeadsBecause of the wider bandwidth, newly developed tape
is required. Basic details of the tape construction areshown in Fig. 2. George Cole's article in the August 1988issue described the tape in some detail. The magneticlayer consists of ultra -high density cobalt -coated ferric -oxide particles applied with a binding agent that ensuresuniform distribution. The surface is incredibly smooth.
The new tape provides increased output at the higherfrequencies and reduced noise. The characteristics thatmake this possible are an 80 per cent increase in magneticenergy, higher coercivity (800-900 Oersteds) and higherremanence compared to standard VHS tape. The cassettehas an identification hole at the bottom, in the rear left-hand corner when viewed from the bottom.
The S -VHS system also requires the use of a different
Nick Beer
type of head. The amorphous type used has been em-ployed in professional equipment and also in some newermachines. Its laminated structure reduces eddy currents,improving the reproduction efficiency especially at thehigher frequencies. Noise is reduced by lowering thefriction between the head and the tape.
S -VHS EquipmentAll the S -VHS machines released so far are "dual-
standard", i.e. they will record/playback to the VHS or S -VHS standard. The identification hole in the cassetteprevents VHS recording with S -VHS tape and vice versa.There is of course incompatibility between the VHS andS -VHS tapes and signals.
Keeping the chrominance and luminance signals sepa-rate is a feature of the S -VHS system. Use of a low-passfilter to separate the luminance from the chrominancesignal to be recorded would have the disadvantage thatluminance information above 4MHz is lost whilechrominance information is still present in the luminancesignal spectrum. Instead, a comb filter is used. It employsa 128µsec (two line period) delay line with addition andsubtraction of the delayed and direct signals - theprinciple is similar to the use of a delay line in a PALdecoder. The chrominance signal is taken off via abandpass filter.
The comb filter technique gives rise to a problem whenthere is no line correlation in the video signal -a form ofdot interference can be introduced. The problem arises in

particular when switching from a monochrome to a coloursignal and vice versa. To overcome this a non -correlationcircuit which detects the presence of the 4.43MHzchrominance signal is used. It generates a non -correlationpulse when it detects this condition.
To ensure optimum conditions, separate luminance andchrominance signals can be fed into and out of S -VHSmachines. Fig. 3 gives details of the four -pin S socket andthe peritel socket connections for S -VHS use.
A 4.43MHz pilot burst signal is added to the line syncpulse whilst recording and is removed during playbacksignal processing. Its purpose is to indicate by its phasewhether the signal being recorded consists of compositevideo or component video (luminance plus chrominance).For composite video the pilot burst phase is 90° withrespect to the U signal phase axis while for componentvideo its phase is 270°. With composite video a luminancecomponent at about 1MHz is present in the chrominancesignal and is not, of course, removed by the bandpasschroma filter. If not removed it gives rise to a dot patternon the picture. A 1MHz trap is used to delete it, beingswitched in automatically when a 90° pilot burst is
detected.During playback the machine must establish whether
the recorded signal is of the VHS or S -VHS type. This isdone by checking whether the output from the playbackpreamplifier contains a 3.8MHz (VHS) carrier compo-nent. A peak detector amplifier is used for this purpose.Its output is integrated and smoothed and is then used tocarry out the appropriate switching. With S -VHS thecarrier deviation is 54-7MHz and the output from thepeak detector will be low.
In conclusion, my thanks to Panasonic for providinginformation. My first impressions of S -VHS are of theundoubted improvement it provides. I think that theboom will come in the camera section of the market as thedifference is more noticeable and the price differential issmaller. A camcorder costs around £1,600 compared to£1,300 for the equivalent VHS type. The Panasonic NV-FS1 VCR costs around £1,000 and includes hi-fi stereosound and a NICAM decoder. At present there's a certainamount of confusion amongst customers as to whether anew 1'V set and VCR (for camcorders) will be required.This is not being helped by lack of sales staff training. Anadvantage of having an S -VHS camcorder is that an editedcopy of an S -VHS recording can be made on to VHS ofequal quality to an original VHS recording, i.e. there's noloss of quality as there would be when copying from amaster VHS recording. This means that there is somecompatibility between the two systems.

LettersDEALING WITH SM DEVICES
I read with interest Ian Bowden's letter (January issue) onreworking surface -mounted components. The company Iwork for has recently invested in equipment for surface-
mounted production and as a result I've had to findsuitable rework methods and equipment.
I found that a large number of equipment manufactur-ers were willing to sell me infra -red or hot-air reworkequipment, usually including precision X -Y -Z move-ments, microscopes, compressed -air solder cream dispens-ers and so on. While these items may be desirable forprofessional or military applications, they would involve avery large financial outlay (thousands of pounds) andanyway I've found that they are quite unnecessary.
I remove small chip components (resistors, capacitors)using a pair of electrically heated tweezers. These areavailable from some large electronic component distribu-tors. They are rather like a soldering iron but have twospring -loaded elements and two tweezer -like bits whosetemperature is adjustable over a wide range by means of aknob on the associated control box. Components can beremoved and replaced in seconds using the tweezers.
Surface -mounted i.c.s most commonly have the gull-wing dual -in -line package. I use a hot-air pencil to removethese. Again there are a number of these items on themarket. Points to look for are a hot enough temperatureand the ability to set the air flow to a very low value withabsolute smoothness and regularity of flow. If this cannotbe done the tool is useless for resoldering with soldercream - it gets blown all over the board. Don't assumethat well-known manufacturers' items are suitable in thisrespect. I've not found it necessary to use an inert gasinstead of air though some units have provision for this. Itwould probably give better joints.
Using a hot-air pencil I remove an i.c. as follows. Inserta pair of extractor tweezers (e.g. RS549-820) under thei.c. and heat one row of legs. When all the solder hasmelted, gently lever the row of legs clear of the board.This obviously stresses the opposite row of legs, so it mustnot be overdone or you will end up with lifted tracks.Now heat these other legs and lever them up - the i.c.should then lift clear of the board. Clean the PCB padswith desoldering braid and a conventional soldering iron.
I.C.s can be replaced using either solder cream and ahot-air pencil, soldering one row of legs at a time, or lowmelting -point solder and a conventional fine iron. Don'tworry unduly if solder cream appears to bridge adjacentlegs - it usually goes to all the right places when heated!Some care is required to apply just the right amount, andhere a compressed -air dispenser is useful. Too muchcream will certainly lead to bridging and if it gets underthe i.c. it will remain there as the heat cannot reach it.
I've not had to remove and replace the square flat -packi.c.s with legs on all four sides (thank goodness!) but I cansee that with these it would be necessary to desolder theindividual legs.
To summarise, I would suggest that anyone who repairsequipment using surface -mounted components shouldconsider purchasing the following: electrically heatedtweezers, a hot-air pencil and an ultra -miniature solderingiron. Smaller items should include: low melting -pointsolder (contains silver, which prevents leaching with some
components), tweezers and large needles (very useful!).I've found one particular range of surface -mount toolsuseful and of excellent quality. They are made by aGerman company, Daturr, and are distributed by STCComponents, Verospeed, OKI Industries and perhapsothers. The hot-air station costs approximately £500 andthe heated tweezers approximately £200.
Finally, try to order components that are marked - itmakes life a lot easier. Surface mounting is nothing tofear, though it may be an incentive to get some newglasses!Paul Barton,Harrogate, North Yorkshire.
FERGUSON TX10 CHASSISEvery picture tells a story: how many readers spottedsomething wrong with the TX10 chassis picture shown onthe front cover of the January issue? K. Rutherford'sexcellent article on servicing the Ferguson TX10 chassismentioned insulation breakdown with earlier focus con-trols. This is something of which most of us are by nowwell aware, and we fit the modified type that includes twoplastic pillars to stand the control off the metal chassis.Obviously the repair technician who dealt with the setshown in the picture didn't see the need to fit these!Alan Shaw,Bolton, Lancs.
EHT ARCING
I was interested to read the article on dealing with e.h.t.arcing (January issue) and found much of what it saidboth valid and good sense. I feel I must take the author totask on a couple of points however.
First, it's not true that manufacturers don't see fit tosmear silicone grease under the cavity connector's cover.My company handles a lot of repairs to ultra highresolution video monitors, and with these it's by no meansuncommon to see large quantities of white silicone greasein this position. Notably one very large Japanese manufac-turer who also makes TV sets does this.
Secondly, the use of silicone rubber compound aroundareas that are likely to discharge is also widespread. WhileI agree that this compound should not be used to "seal in"faults, I see no valid reason why it shouldn't be used toprevent the ingression of moisture into likely troublespots. Indeed I have modification instructions, from thesame Japanese manufacturer, advocating its use.
Finally I don't believe that just because the manufac-turer didn't do it in the first place this is a reason for notsubsequently doing it. I could cite many cases where setsare installed in houses belonging to old people who smokeforty cigarettes a day and run a Calor gas heater throwingout about a gallon of water an hour, the result being thatthey go through an e.h.t. connector about once everythree months. The only permanent cure for sets operatingunder these conditions is to seal the cap so that themoisture canot get under it in the first place.G.H. Darby, Proprietor Monitech,Earls Barton, Northampton.
PROBLEMS WITH RANK SETSMay I say thanks to Colin Doman (Letters, January) forhis suggested modification to get rid of the accursedteletext lines with sets that use the Rank A823 serieschassis? I'd been struggling for some time with one of

these sets. I'd tried Mr. Catchpole's suggestion of extrawindings on the line output transformer but the lines werestill visible. The net result was to increase the field scan byten per cent, out of the range of the height control. It's auseful idea however if the 40V line is still low afteradjusting the h.t. to its correct level of 200V - cheaperand quicker than replacing the LOPT. John de Rivaz'spulse generator circuit didn't help but Colin's modificationhit the nail, or perhaps I should say the teletext lines,squarely on the head. Well done Colin Doman. Tenminutes after reading his letter I was out of my misery.
Much has been written about the shortcomings of theRank -Bush -Murphy channel selector pushbuttons. Here'sa way of making those dreaded nylon bushes so belovedby Rank. First obtain a number (as required) of 22mmdiameter by 4mm thick nylon washers. Remove the tunerfrom the set, unplugging all the leads. Dismantle thebutton unit on a table or bench, noting the positions of allthe buttons, washers, springs and screws. Place them outof harm's way before beginning the next phase of theoperation, which is to remove the broken bush from thesprindle and also circlip A - see Fig. 1(a). Since the circlipis made of mild steel, with a little care it's unlikely tobreak.
Place the nylon washer in a vice and drill a 7/32in.diameter hole in the centre. The point to note here is thatyou will be using the threaded part of the spindle to makea thread in the nylon washer, so gently does it whendrilling - if too much material is removed it won't bepossible to thread the washer. While the washer is still inthe vice, push the spindle into the hole from the cross endand carefully twist it, using pliers if necessary (a smalldrop of thin oil on the spindle will help), until a thread hasbeen cut.
Remove the washer from the vice and mark it out asshown in Fig. 1(b). Remove the excess material, using asmall hacksaw and a file to complete the bush. Fit the newbush on the spindle, taking care over two points. First thatthe bush is fitted the correct way round, and secondly thatit runs smoothly along the thread of the spindle. Remem-ber that you will have to carry out the tuning procedurewith the tuner installed in the set, using those horridbuttons. Finally, as all the best manuals say, reassemble inthe reverse order.

SERVICING PRECAUTIONSAs expected, my article and subsequent letter on theAmstrad CTV2200/2210 produced some comments. Mythanks to J.E. Jones (January) for his interest and the tipabout C845.
Another point - which could apply to many another TVset or VCR - is that the fuses (F501/2) are often loose intheir clips. I always remove both and retension all theclips by bending, at the same time checking the fuse typesand ratings. They can easily be overlooked as a result oftheir inaccessibility. Similarly we always check theplugtops of all items that enter the workshop. Mostrequire refitting. The fuse ratings, clips and cord grip canbe inspected at the same time.
If a set has lost its feet we always replace these toensure adequate ventilation - even if the set lives on astand (someone may remove it one day!).
In reply to S.J. Cain's interesting letter, anyone whoregularly services a large cross-section of CTVs will knowthat it's often impractical and sometimes impossible toreplace semiconductor devices with the original types.This is, after all, why we have equivalents books! Use ofthese, coupled with experience, will enable a good, sound,safe alternative type to be fitted. A device that is "better"than the original can usually be selected. I keep a verylarge stock of semiconductor devices, but it's impossible tokeep every type and customers are not prepared to waitweeks while the exact part is obtained. It would have been
TELEVISION MARCH 1989 337
almost a year in the case of the 2SC3156 transistor!When the first Amstrad CTV2210 came into my work-
shop I borrowed a service manual and a 2SC3156. A fewdays later it failed again. At the time spares could beobtained direct from Amstrad, but neither the manual northe 2SC3156 was available. The latter item was on orderfrom Japan. Maybe Mr. Cain had bought the lot? When Iopened an account with CPC it was the same story. Iwrote to Amstrad's technical department for advice abouta suitable alternative, but didn't receive a reply. As nodata on the 2SC3156 was available, the circuit was studiedand several alternatives were tried - successfully. The ideaof using a D type with a parallel diode and base -emitterparallel resistor was to provide the device with greaterprotection against mains spikes, which could have contrib-uted to its failure. We can't always assume that electricalinstallations/adaptors are perfect.
Incidentally the Amstrad spares agent doesn't seem tobe able to obtain R814, a special 20W, 2751 resistor thatfixes to the chassis via a steel bracket. Under the partnumber a standard 17W, 275/ wire -ended resistor issupplied. I don't consider that this is a valid replacement:not only is it lower rated, but the bracket doesn't fit.
To put the matter of safety into perspective, if a fire didoccur negligence would have to be proved. Provided thatrepairs are carried out in a careful, neat, sound andworkmanlike manner (unlike some I've seen perpetratedby so-called trade engineers), that any equivalents fittedare carefully selected, that safety components are replacedwith the same types, that fuse ratings and types as well ash.t. rail voltages are checked as a matter of course, thenno problems should arise.Dave Mackrill,St. Leonards on Sea, East Sussex.
A Simple Channel 1 ModulatorIn the November and December issues last year I wrote indetail about 405 -line TV and mentioned a Rediffusionmodulator conversion. A letter in the January issuepromised further details of this. The unit concerned iscalled a translator and is available at very modest cost. Itcontains a u.h.f. tuner with i.f. strip that provides videoand audio (to drive a loudspeaker) outputs, an h.f.converter, an h.f. modulator and a power supply.
Until now most people who wanted a Band I modulatorbuilt David Looser's excellent design (Television, October1984). Making use of the Rediffusion units provides asimpler approach with equally high -quality results. Youhave to buy two of the Rediffusion units to obtain twomodulators. This will leave you with two perfectly goodoff -air tuners - see later.
Modulator ConversionThe first step is to extract the h.f. modulator can - it's
the tuner -like can on the right-hand PCB, near the mainstransformer. The circuit of this module is shown in Fig. 1.Conversion details are as follows.
Replace R2 (vision modulator only) with a 3.9kflresistor.
Replace R8 with a 56012 resistor.Replace C7 with a 22011 resistor.Replace R13 with a 10pF capacitor.Replace C8 with a 68pF capacitor.Replace C9 with a 47pF capacitor.Delete R22, C16 and C12.In the sound modulator, remove Tr2 and connect a
47kS1 resistor between the base and emitter connections.Replace X1 with a 41.5MHz crystal in the sound
modulator and a 45MHz crystal in the vision modulator.Add a 2.2kSi resistor across the crystal on the back of thePCB to provide damping.
Add a 100pF capacitor from the carrier test point tochassis.
In the vision modulator, add a 1N4148 diode in serieswith R1 (cathode to R1).
These points are all shown in Fig. 1.Connect the r.f. OV pin to the modulator's case.The r.f. output obtained from the circuit shown in Fig.
Jeffrey Borin, B.Sc. (Eng.), A.C.G.L, M.LE.E.
1 is about 30mV r.m.s. The arrangement shown in Fig. 2provides two r.f. outputs, with the vision at 22mV peak -
to -peak and the sound at 10mV peak -to -peak.Each modulator is best aligned with the other one
turned off. It's easy with a wide bandwidth scope lookingdirectly at the output. Otherwise look at the demodulatedvideo using a receiver or diode probe. Set Ll for maxi-mum output. It tunes very broadly and the tuning is notcritical. With the vision modulator feedvideo signal (625 will be perfectly o.k.) and set RV1 forpositive modulation with zero carrier at the sync tips. Ifmonitoring demodulated video, set RV1 so that synccrushing is just avoided. Without a scope, adjust RV1until sync fails, then back off a bit. With the soundmodulator, use RV1 to set the unmodulated carrier to10mV peak -to -peak. Alternatively feed in about 100mVof audio tone, with the gain control at maximum, andadjust RV1 until distortion is just heard on the demodu-lated sound.
If you don't want to order crystals specially you couldtry using a series LC circuit, adjusting on test with acounter. Omit the 2.21(11 damping resistor.
I have not had a chance to look at the modulator'soutput on a spectrum analyser - if some lucky person hasone, could they please tell me just how revolting theoutput looks!
These modifications have been thoroughly proved onChannel 1 but not on the higher channels. With appro-priate crystals they should work throughout Band I, butthe MC1496 modulator chip is not really suited to BandIII use.

Using the Tuner
You now have a working Channel 1 modulator. Whatabout the tuners? Here's how to get the best from them.Fig. 3 illustrates most of the following points.
First ensure that only the mains input flex goes to oneside of the mains switch. The other side of the mainsswitch should go to only the L and N tags on the power
101231
supply panel. Mains earth must be connected to the earthtag at the front right of the power supply panel.
Remove all wiring to the "octal" output plug and"octal" socket on flylead. Remove the lead to PLB on thepower panel but retain for reuse. If the h.f. modulator isto be converted to a Band I modulator remove it from thepower panel.
Install sockets on the back panel for video (suggestBNC), audio (suggest phono or XLR) and loudspeakeroutputs. Alternatively a small speaker could be squeezedinto the case. I've not tried this, but if you want a linelevel balanced output T2 on the power panel might beused to match the speaker level output. Volume wouldthen have to be preset.
Clip the wires from SKE on the power panel. This pairoriginates at PLE on the signals panel. Connect the freeend to the loudspeaker or socket.
Use the lead and connector removed from PLB toconnect the video output from SKF (virtually at the front,under the tuning button assembly) to the video outputsocket. Include a 1005I resistor in the inner to get the levelabout right. It would be possible to design a T -sectionnetwork to give an accurate output match.
Take the audio output from PLD - refer to Fig. 3.Fit a 100kfl potentiometer on the front panel to act as
the volume control. Connect to PLA and PLC as shownin Fig. 3. The preset control previously used as the volumecontrol, on the power panel, can be used to set themaximum volume.
If all eight tuner buttons are stuck in they can bereleased by pushing the latch bar with a small screwdriver.This is not obviously visible. Looking at the back of thetuning assembly, reach into the left side beyond buttonseven. The latch bar is level with the buttons, virtually atthe front of the assembly.
Under the mechanism, behind each tuning button,there's a fine leaf spring. This is actually the bandswitchused to select between u.h.f. and Rediffusion h.f. Buttons1-7 are normally set to u.h.f. and button C to h.f. It'ssimple if rather fiddly to change the C switch to u.h.f. bysetting the spring to the same position as on buttons 1-7.
If the door over the tuning presets is missing or the littleorange trimming tool is absent, the a.f.c. will not work. Avariety of possibilities can be adopted, from matchsticksand sticky tape to a separate proper a.f.c. switch.

TV Fault FindingRank T24 Chassis/Toshiba C1695B1 etcThis fault fooled one of our engineers since it producedsymptoms similar to those with a duff line output trans-former - at switch -on the set gave one squawk then shutdown in the standby mode. The effect was of heavyloading in the line output stage and was due to zenerdiode D472 in the overvoltage protection circuit beingleaky. It's a 6.2V device, type BZX79B6V2. E.T.
Philips 2B ChassisWe have a large number of the version two of this chassisout and are beginning to get a steady stream of them backin the workshop with the BUT12 chopper transistor short-circuit. In all the cases I've seen there have been dry -jointson the chopper transformer. I haven't had a set fail afterresoldering these joints. Philips recommend however thatif you experience further BUT12 failures for no apparentreason the device should be replaced with a 2SC3973Band the value of R3671 should be changed to 221/, 5W.
When the BUT12 fails it sometimes goes short-circuitcollector -to -base, which rather upsets the rest of thepower supply. Usually it damages T7686, 17685, D6686,D6672, D6671, D6670, D6690, R3687, R3670 andC2690. P.B.
Grundig Cinema 9050
The problem with this projection set was intermittent nosound or vision. When the fault occurred the mainsvoltage didn't reach the TV power supply. Relay 601wasn't pulling in because T6021 on the "omniplatte"wasn't being turned on.
At the top left-hand side of the set (viewed from thefront) there's a microswitch that should operate when thescreen is up. It was faulty. P.B.
Philips NC3 ChassisThis set came in with a shorted BUT11 chopper transistor.After a fruitless check on the components that couldpossibly have led to its demise we fitted a replacementwhich immediately failed. The cause of the trouble wasthat R418 was open -circuit. This resistor is connectedbetween pin 9 of the chopper transformer and the junc-tion of L403/R409, not in parallel with R425 as in all thecircuit diagrams we've seen. P.B.
Sony KV2052
One of these sets came in recently with a blown up powersupply. A major rebuild cured the problem for two daysafter which it again blew up. The cause of the troubleturned out to be a pinhole in the chopper transistor's micainsulating washer. M.D.
Grundig CUC41 ChassisThere was no output from the power supply, with aticking noise coming from within the set. The +A rail waspulsing very slightly. H.T. was present at the collector ofthe chopper transistor and there were no shorts on the
Reports from Eugene Trundle, Mick Dutton,Philip Blundell, Eng. Tech., Ian Bowden,Alan Shaw, Roger Burchett, John Coombesand Hugh MacMullen
output lines. As we couldn't find any obvious fault weresorted to checking components individually. We even-tually found that R651, which is in series with the set-H.T.control, had gone open -circuit. M.D.
NordMende RV ChassisThis elderly 26in. colour receiver suffered from reducedheight. We spent a considerable time checking around thefield output stage only to fmd that when the field oscillatortransistors were given a squirt of freezer the heightreturned to normal. As there was no tendency to field rollwe had initially ruled out the oscillator stage. M.D.
Sharp C2092The customer's complaint was that the picture would gooff intermittently. On soak test we found that when thefault appeared the screen went blank white, with somedeterioration of the sound. The cause of the problemturned out to be IC401 (IX0118CE) which contains aclamping circuit. M.D.
Salora J20 SeriesThe symptom was no line lock. A scope check at pin 11 ofthe TDA2594 sync/line oscillator chip ICB501 showed thata suitable video waveform was present - and also clearedthe fault! The scope had been set to d.c. input: whenswitched to a.c. the fault was still present. A look at thecircuit suggested that RB514 (2.7M11) could be responsi-ble for the trouble and when checked it turned out to beopen -circuit. I.B.
B and 0 33XX Series with TextThere were three problems with this set. First when textwas selected the required page number couldn't be ob-tained - you simply got 100. Secondly the on -screenchannel number couldn't be brought up with the remotecontrol unit's TV button. And finally when trying to selecta channel above nine the on -screen display would justflash on then off instead of staying there for three secondsso that you can select the second digit of the channelnumber. All three problems were caused by a faulty 4015shift register chip (8IC1) on the remote control decoderpanel. I.B.
Salora 16J20
This set had an odd cyclic fault. Every ten -fifteen secondsthe picture would gradually darken then, with a ping fromthe degaussing circuit, it would jump back to the correctcontrast level, usually with a bad purity error. The noiseand purity problems would go if the degaussing coils weredisconnected, but the picture contrast would continue tovary as before. A check on the beam current limitervoltage (across CB503) showed that this dropped as thepicture darkened. This is the opposite of how it shouldwork, i.e. when the beam current rises (high contrast/brightness) the voltage should fall in order to limit the
340 TELEVISION MARCH 1989
drive from the TDA3562A colour decoder chip, usingtransistor TB200 to hold down the d.c. brightness andcontrast control inputs. The cause of the fault turned outto be a dry -joint on the upper connection of the screening"wall" between the colour decoder and the RGB outputstages. This wall is used to link a chassis return from thec.r.t. base to the main panel. Loss of this connectionmeant that the grid supply potential divider had no link tochassis. I.B.
Philips K40 ChassisWe've had a couple of faults on these sets recently. Thefirst one incorporated teletext. It had a dark picture andthe contrast control was inoperative. Tr7116 (BC558B) onthe teletext interface panel was short-circuit base -to -emitter.
Predominant blue with faint flyback lines visible was thefault on the second set. The blue output transistor'scollector voltage was low at 100V instead of 160V becausethe h.f. compensation capacitor C2216 in its emitter circuitwas leaky. A.S.
Quick ChecksLoewe MS56: For no sound and vision check whether theline driver transistor's supply resistor R534 (IMO is open -circuit. If the h.t. is high at around 230V (should be 142V)check C638 (1µ.F).Toshiba 221E: For field foldover at the top of the screencheck C313 for loss of capacitance.Toshiba 2226: No line sync - check whether R402 (15k11)is open -circuit.Philips CTX chassis: Tripping has been traced to theBYV95A 26V rectifier D6590 being short-circuit.Sharp C1871: For intermittent partial field collapse checkR525.Ferguson TX90 chassis (20in. version): For lack of heightcheck whether D106 is leaky.Amstrad TVR2: This 14in. CTV plus VCR combinationcame in with the complaint that it was dead. There was ameasurable short across the collector and emitter of theline output transistor. D1606, type FR304, was short-circuit.Hinari VTV100: This combination 20in. CTV plus VCRcame in with a high raster brightness fault. We found thatthe 2SA1015 luminance amplifier transistor 0301 wasshort-circuit emitter -to -collector. A BC307 proved to be asuitable replacement. A.S.
Rediffusion Mk 3 ChassisFor tuning drift don't strip the selector unit or suspect thetuner. Resolder pin 8 of socket OPLA (at the top of thesignals panel). This fault is becoming very common. It willsave you time and trouble if you do this with every Mark 3that comes into the workshop. R.B.
Rank T20 ChassisIntermittent failure to start up from cold was the problemwith this set. It would continue to work after bridging thestart-up capacitor 4C19 (10µF). 4R16 (9101/) and 4C19were original components and were replaced. Numerousdry -joints were resoldered. But after leaving the set forhalf an hour it refused to start. I noticed a certainreluctance to start up even with the bridge in place.Turning the overvoltage trip control down improved the
starting. [ then tried to set the overvoltage trip but foundthis very difficult. It transpired that 5D5 (1N4148) on thetrip subpanel was dead short. I've had this before, after atripler failure, but the set then refused to start at all. Put itdown to experience. At least this particular T20 has hadall the stock faults attended to.
Similar symptoms to the above - intermittent failure tostart, eventually leading to a "dead" set (h.t. present butno line timebase action) - usually means that the collectorof the 12V regulator transistor 4VT7 (2N5296) is goingopen -circuit. R.B.
Decca 70 Series ChassisVery intermittent failure to start, which could not betraced to a bad joint and did not appear to be affected bytapping or flexing the board, was eventually traced toR625 (180k52, 1W) in the start-up circuit. It had a crackalmost completely around the body. R.B.
Sanyo CTP3105 (79P Series)For no sync check first whether R403 (11(11) is open -circuit, then check the syndline generator chip IC401(LA1460) by replacement. J.C.
Hitachi CPT1444/CPT1446II the screen flashes red, green or blue when the channelis changed replace IC501 (TDA3562A), reduce the valueof R726 (6801/) to 56011 and change R610 from 12k11 to8.2ka
If there's no sound and no raster and the mains fuseFS901 is open -circuit this item can be uprated from1.25AT to 1.6AT. J.C.
Toshiba C1410For no signals on all channels, first ensure that 15V ispresent at the emitter of the 2SC1166 series regulatortransistor QE01 on the selector board. Next check the33V line at the junction of RE06 and DE03 (ZTK33B). Ifthis line is low or absent, replace DE03. Then if necessarycheck ICA01 (TA7177P) and/or ICA02 (TA7178P) byreplacement. J.C.
Hitachi CPT2236/CPT2238If the receiver is permanently in the standby mode checkwhether R1437 (82011, 0.25W) is open -circuit. If so fit a1W replacement. J.C.
Rank Z718 ChassisThere was no line drive. After quite a bit of searching onthe scan drive panel we found that the printed link fromthe anode of the 8.2V zener diode 4D12 to chassis hadblown off. There was thus full h.t. on 4D11 and at pin 4 ofthe TBA950 sync/line generator chip 4SIC1. We madegood the chassis connection and changed the chip only tofind that in addition 4D12 was open -circuit. H.MacM.
Philips G8 ChassisThe h.t. was 256V and couldn't be adjusted. The setemployed the very early power supply panel with thezener diode in the BC147 control transistor's base circuit.R1365 had increased in value from 471(11 to60k11. H.MacM.

Camcorder ServicingPart 2
There are two basic sections of the JVC Videomoviecamcorder, the camera section and the VCR section. Asthe two are contained within the same housing somesimplification is possible, with shared facilities. The resultis a reduced component count and less power consump-tion compared with the use of separate pieces of equip-ment. The power supplies are shared, with use made ofd.c.-d.c. converters to develop the various voltages andsupply lines required. This makes for easy switchingbetween the record and playback circuits. It also enablesthe camera section to be controlled via the microcomputersyscon (system control) circuitry associated with the maindeck. Fig. 1 shows an overall block diagram of the cameraand recorder sections.
Camcorder Block DiagramFor recording purposes the video signals are obtained
from a half -inch, high -band Saticon pickup tube or a CCD(charge -coupled device) image sensor. The signals have tobe decoded, then processed to be PAL compatible in aform suitable for recording. We will be describing theindividual processes involved later. The luminance andchrominance components of the signal are fed to separaterecording circuits and are then added for application tothe heads via the switching system described last month.
The sync signal generator (SSG) produces all the timingsignals. It provides outputs to drive the deflection circuits,which also produce the high voltages needed for correctSaticon tube operation. Sync, clamping and 4.43MHzcarrier signals are supplied to the video processing cir-cuitry by the SSG.
Before application to the frequency modulator theluminance signal is passed through a low-pass filter andthen a dynamic aperture corrector (DAC). Thechrominance signal is passed through a bandpass filter(BPF) not so much to provide filtering - the signal isalready at 4.43MHz - but to provide correct timing. Asmall delay is required to match the timing of the lu-minance signal during record. Down -conversion and col-our level control follow standard practice.
Part of the luminance and chrominance signal is tappedoff prior to the recording circuits to provide a compositecolour signal which is used for E -E monitoring. Theelectronic viewfinder is also linked to this line, via a low-pass filter to prevent colour dot patterning.
Playback follows standard VHS practice. The signalsfrom the video heads are switched, as we saw last month.The luminance signal is limited and demodulated whilethe chroma signal is up -converted and phase corrected.The two signals are then added to provide a compositeoutput signal.
Record only camcorders are somewhat different. TheSSG provides timing signals to encode the R -Y and B -Y colour -difference signals at the down -converted fre-quency of 625kHz. There's no 4.43MHz colour signalavailable within these machines for setting up, so an up -converting jig is required to connect to the camera head topower it and provide a composite, baseband output.
Audio recording and playback are fairly standard.Recording is possible only via the inbuilt microphone and
Steve Beeching, T Eng.
can be monitored from the main output socket or viaearphones. Naturally there are variations on this arrange-ment. Some machines allow an external microphone to beused and in rare cases there's provision for external AVinputs.
The Saticon TubeThis instalment will deal mainly with the Saticon tube
used in models that employ a thermionic pickup device.Fig. 2 shows the basic items associated with the tube.
The incoming light passes through the camera's zoomlens, a colour -temperature filter, iris, master lens andcrystal filter, being focused on to the tube's faceplate andphotosensitive target area. Within the tube an electronbeam scans the opposite side of the target area. It'sdeflected electromagnetically, conforming with a standardscanning system, i.e. in Europe 625 lines, 50Hz - theprinciple is the same as with TV tube scanning. As theelectron beam scans the target, variations in the lightintensity at various points of the target cause variations inthe beam current. Some beam current flows even withoutany light. This is very small, in the range of picoamperes,and is called the dark current. Signal current from thetube is taken from the target. It's a very small currentfrom a high -impedance source and is highly susceptible toexternal interference. For this reason the preamplifier ismounted on the tube, within a screened container thatincludes the very short target connection.The target itself

consists of a complex sandwich layer of selenium -arsenic -tellurium (hence SATicon) film bonded to othersemiconductor layers - see Fig. 3.
The first item after the glass faceplate is a stripe filter.This consists of diagonal cyan and yellow stripes which aredeposited on the inside of the faceplate and overlayedwith glass - we'll have more to say about the action of thisfilter later on. Next comes a transparent layer of stannicoxide which is the target output electrode. This forms ahetero-junction (cross -coupled) with the selenium -arsenic -tellurium layer and the chalcognide glass material.Between the selenium -arsenic -tellurium layer and a layerof antimony trisulphide on the beam side there's a thicklayer of a selenium -arsenic mixture.
Light passes through the faceplate, the stannic -oxideand SAT layers to the selenium -arsenic layer where holesand free electrons are produced. The electrons flow backtowards the faceplate, into the stannic -oxide layer via theSAT layer. Holes cannot penetrate the stannic -oxide layerdue to the selenium film deposited on it by the SAT layer.The holes can travel in the opposite direction however. Indoing so they combine with the scanning electron beamvia the antimony-trisulphide layer. The electrons in thescanning beam cannot pass through the antimony-trisulphide layer due to a film of selenium on the oppositeside. Beam current is thus dependent on the number ofholes created by the light and available for combining. Ineffect the holes form a capacitive "charge" representingpixel elements. For each hole that combines with a beamelectron an electron is released via the stannic oxide layerand the target output connection.
To recap briefly, light produces equal numbers of holesand free electrons in the selenium -arsenic layer. For eachhole that combines with an electron from the scanningbeam an equivalent electron is released via the targetconnection. Hence the current output from the targetdepends on both the amount of incident light and thebeam current.
So much for the theory. Fig. 4 provides an equivalentcircuit that illustrates in a more practical manner whatgoes on. It represents a single pixel element of thephotosensitive target layer. The Saticon's target layer ineffect forms a parallel RC circuit. The value of R varieswith the intensity of the light falling on it. With no light, Rhas a finite value which is designed to be as high aspossible to minimise the standing dark current. As thetarget is scanned by the electron beam, each pixel islinked to the beam once per frame. Contact between thebeam and a pixel is represented by switch SW. When theelectron beam arrives at the pixel the switch is in effectclosed. The capacitive element is then charged via thetarget and the tube's cathode - the beam effectivelyconnects one side of C to the cathode. When the beamhas passed, C begins to discharge via R whose value, aswe've seen, is light -dependent. With no light R has a highresistance and C can discharge only a little. If the lightlevel is high the value of R is small and C's discharge canbe high. The next time the electron beam passes the pixel,the amount of beam current that flows through the targetload resistor R1 is the current required to recharge C.Thus with a high light level the current flowing via RI ishigh and the signal voltage developed across RI is rela-tively high.
The target output signal is therefore dependent on therecharging current at each pixel capacitor and the light -dependent value of the associated resistance. As theSaticon's electron beam scans a TV line, many hundredsof small capacitive elements charge. The varying chargecurrent that flows via the load resistor develops a signalvoltage which is connected to the camera's preamplifiertransistor Tr via the coupling capacitor Cc.

Fig. 5: The Saticon tube's gun structure, showing theelectrode operating conditions. The target is connected tothe front rim and the mesh (G6) is internally connected toG3. Blanking is carried out at the cathode. A scope con-nected to G1 will show the blanking pulses at about -70V.
While the signal voltage developed across RI is verysmall, it has a very good signal-to-noise ratio, i.e. anextremely low noise content. To maintain this low -noisecondition, the first stage of the preamplifier uses a low -noise junction field-effect transistor selected for its low -noise characteristic. LI is called a Percival coil. Itresonates with the target's capacitive output, lifting theoutput at the higher frequencies. With a colour camerathe resonant frequency is 4.3MHz, which is the R/Bcolour carrier frequency obtained from the tube (more onthis next month).
Saticon OperationThe internal arrangement of the Saticon tube is shown
in Fig. 5. At the faceplate end there's an external targetconnection, the target flange or rim. A small leaf springcontacts the rim and is soldered to the Percival coil at theother end.
One danger when servicing cameras fitted with aSaticon tube is the presence of high voltages on theinnocent looking PCBs. While a shock is not lethal, it canresult in demise of the camera if the camera is dropped asa result of receiving a shock. This is especially the casewhen there's a capacitor that doesn't discharge at switch -off connected to grid G6.
The highest voltage is the mesh voltage. This is usuallyin the range 1.4-1.6kV and is internally connected to gridG3. Grid G5 is a collimator lens to narrow the beam as itapproaches the target, and is at 700V. It operates inconjunction with the voltage, which is variable between200-300V to provide electrostatic focusing, at grid G4. Ifthe beam is not focused the tube's resolution drops andthe R/B colour carrier falls to zero, leaving a greenpicture. Adjusting the focus control will rotate or twist thepicture about the centre. It can be used in conjunctionwith external beam shift magnets to centralise the beamlanding. A spot in the centre of the picture must stay putwhen the focus is adjusted and not shift off the centreaxis. This sort of adjustment will however create purityand shading problems that will take hours to sort out!
Grid G2 is the first high -voltage electrode, its purposebeing to accelerate the electrons that leave the cathode.G1 is a reverse biased grid: the bias voltage is variable toset the beam current to a value which is sufficient tocharge the target capacitance at full white, without beingexcessive so that the target is saturated. The visual effectof reducing the beam current below the nominal value isto clip the peak whites. The correct setting is for justabove maximum peak white voltage at the signal output.Too much beam current will adversely affect the focusingand twist the picture.
The cathode sits at about 6V above chassis potential.
Field and line blanking are carried out at the cathode -the blanking pulses have an amplitude of about 64V peak -
to -peak. If the cathode blanking drive chip fails it will shutoff the tube.
An oscilloscope connected to the beam current grid G1will display negative -going blanking pulses down to about-70V, with a black level of about -50V upon which thevideo signal can be seen. This check will indicate whetherthe tube is operational even when there's no output duesay to failure of the preamplifier.
Beam DeflectionWhile the focusing is electrostatic the deflection is
electromagnetic, achieved by means of a deflection yokearound the tube. Shorted turns in the yoke can stopdeflection, resulting in no output from the target and nosignal at Gl. Loss of field drive will produce the sameeffects. Line deflection is linked to the high -voltagecircuits, as with a TV set, and failure of the line scanusually results in no high voltages.
No Camera PictureWhat do you do if there's no picture from the camera?
First check that the high voltages are about right, nextcheck that the scan outputs to the deflection yoke arepresent, then check that the cathode drive pulses arepresent and correct. If these things are all right, turnattention to the tube's preamplifier. This can be checkedonly by access to the target connection, involving partialremoval of the tube. If the preamplifier is o.k. there willbe massive amounts of noise when you go near it, due tothe very high impedance and sensitivity.
Bias LightThe bias light - see Fig. 2 - is present to reduce lag or
after -image effects as a result of the dark current beingtoo small. It illuminates the target. The theory here is asfollows. When there's a rapid change from bright light todark, it's possible for the target's capacitive elements to beleft with residual charges that cannot be discharged via theassociated resistance between beam scans because theresistance value is too high. These charges show up as anafter image. The effect can be reduced by using a small lightto bias the target, thus maintaining a lower resistance leveland hence increased discharge of the capacitive elements.The bias lights can be LEDs, mounted around either thetube face or the tube base to backlight the target.
Crystal FilterThe crystal filter is used to reduce cross -colour effects
or moire patterning in scenes that incorporate smallchequered patterns or fine stripes. If fine patterns ataround 4.43MHz in the luminance channel of a TV set areallowed into the colour circuits random blue/purple moireherringbone patterns will be seen. Similar problems arisewith a camera. Scenes that create luminance signalcomponents at around the R/B carrier frequency of4.3MHz will produce similar effects. The crystal filter isincluded to prevent this. It consists of an optical spatialfilter with gratings effective at 4.3MHz, thus effectivelyblocking fine patterns before they reach the target.
Next month we will take a look at colour signalprocessing.

The Pros and Cons of LocoScript 2
When the Amstrad PCW8256 was launched it was hailedas the poor man's word processor. And so it was, for at£399 plus VAT few who regularly used words and putthem down on paper couldn't afford one. This wasparticularly the case since most word processors werepriced in thousands rather than hundreds of pounds.Understandably those who had laid out thousands wentlow over it, and so did the competition. The program,LocoScript 1, was described by some as non-professionaland amateur, and its limitations were fully aired. It didhave limitations, but it also had many features not foundwith the more expensive outfits - the critics had little tosay about these. In an article in the December 1986 issueof Television I endeavoured to give a balanced view,mentioning its pros and cons as well as those of wordprocessing in general.
Since then Amstrad has brought out other models.There was first the upgraded PCW8512 with its seconddisc drive and double RAM M -drive capacity, increasedfrom 256K to 512K (incidentally these numbers explainthe model numbers adopted, the 8 referring to the Z80 8-
bit microprocessor which is the heart of these machines).The 8512 was also supplied with LocoScript word process-ing. Subsequently Amstrad turned to IBM compatiblearrangements. Being thus succeeded the PCW8256 cameon offer at prices down to £299, representing an excellentopportunity for anyone wanting to start with wordprocessing.
Development of LocoScriptUnlike many firms that lose interest in their older
models, Amstrad continued to refine the LocoScriptprogram. LocoScript 1 was taken through several suffixnumbers, then in July 1987 the completely revampedLocoScript 2 was released. Some of the initial reviews inthe computer magazines were clearly done in a hurry andinevitably some of the trivial points were emphasisedwhile important ones were missed. In view of LocoScript2's complexity and the large number of facilities available,it seemed prudent to get well acquainted with it beforedoing a follow-up to my original article.
My copy of LocoScript 2 has been in daily use now for agood few months - often for up to ten hours a day. Thefollowing comments are primarily intended for LocoScript1 users who may be wondering whether or not to makethe change to LocoScript 2. They should also be helpful toanyone contemplating a first plunge into word processing.One can start word processing with LocoScript 2 at a veryelementary level - you don't have to learn a host ofcommands as you do with some other word processingsystems. As you become familiar with the operation ofLocoScript 2 you can start to use and master otherfeatures.
The ManualThe instruction manual was a problem with LocoScript
1. It was difficult for the beginner to follow. As a resultmany books and courses came on offer to help those whowere as baffled by it as I was. Strangely the manual now
Vivian Cape!
doesn't seem so bad and I can follow most of it - but thenI'm no longer a newcomer.
The LocoScript 2 manual is a big improvement. Afterthe preliminary setting up and connection instructions itoutlines the main differences between LocoScript 1 and 2,referring to the appropriate sections of the manual toconsult for detailed information on the changes. Thus itfirst gives LocoScript 1 users an overall picture of thedifferences, after which they can go into the detail.
The main part of the manual is a step-by-step tutorialfor newcomers. It strikes about the right tone, beingneither patronising not too formal. Anyone starting fromscratch should have few problems.
There's a postscript with tips on using LocoScript 2 forparticular applications - business letters, memoranda,magazine articles, technical reports, invoices, circulars,newsetters and so on. Appendices include a glossary of allthe technical and operating terms used, a list of all thecharacters available and how to obtain them, a quick -reference guide with basic instructions for each function,and a trouble -shooting section. All in all it's a comprehen-sive, well thought out and easily understood manual.
Disappointments
One disappointment for me with LocoScript 2 is thelack of a word count, something that's very useful forauthors, journalists, reporters, etc. I find this surprising asa number of features of limited use are included - thecomplete Russian alphabet, playing card symbols, male/female symbols and even black and white smiling faces! Aword count is included with the spelling -checker dic-tionary LocoSpell however. This is available as a separateprogram that works within the LocoScript format withdirect access when working on a document, unlike otherspelling checkers that have to be loaded separately afterthe document is complete. It's twice the price of someothers however, and the main dictionary takes up so muchspace that it cannot be loaded into the 256K memory ofthe PCW8256 - it requires either an upgraded 8256 or an8512. Otherwise the smaller dictionary included on thedisc is loaded and used. This combination of a word countand spelling checker is not such a good idea - professionalusers who would get most benefit from a word count areleast likely to require a spelling checker.
Another disappointment is the fact that you can'tchange existing text from lower case to capitals and viceversa. You can do this with some word processors and I'dhoped the facility would be included with LocoScript 2.It's easy when typing adjacent letters to touch the shiftlock accidentally and thus type a line or so of capitalsbefore you notice them. Instead of being able to changethem you have to erase and retype the lot.
MenusThere are three ways in which you can operate and
choose the various LocoScript facilities: by menus, bykeystrokes, and by using an intermediate method whichwe'll ignore here. The menus consist of a group of relatedoptions that appear on the screen when the appropriate f
TELEVISION MARCH 1989 345
key is pressed. There are four such keys which with theshift key give numbers f1-8. Having called up the rightmenu you move the cursor down it, with the cursormoving key, to the option required. You then press theplus and the enter keys. To cancel the option you do thesame again, this time pressing the minus key. With thealternative keystroke method you simply press the pluskey followed by a one- or two -letter code: to cancel youpress minus followed by the same code. One wonders whythe longer and more laborious menu method was the onetaught throughout the whole LocoScript 1 manual, thesimpler keystroke method being mentioned almost as anafterthought in half a page towards the end. With theLocoScript 2 manual keystroking appears throughout, butis still presented as an alternative to using menus.
The reason given for this is that the beginner uses themenus until he can learn the codes for keystroking. Nearlyall the codes however are the initial letters of the optionsrequired - I for italic, B for bold, CE for centring, RA forright align, LS for line space, U for underline, etc. Onehardly needs a photographic memory for these! This isunlike some word-processing systems with which the lettercodes bear little resemblance to the functions.
My grumble about all this is that there are actuallymore menus with LocoScript 2 than with LocoScript 1.You can avoid many of them by keystroking of course,but many of them pop up without being asked. Forexample to print a document you first press the letter P.Then a menu asks whether you want high quality or draft,more than one copy and whether all or part of thedocument is to be printed. These are all useful options,especially the last one which was not available with earlyversions of LocoScript 1. Having chosen from theseanother menu appears to ask whether you want to use thecurrent paper (the one to which the printer is set) or theone for which the document was set up. As the currentpaper option heads the menu you have to move the cursorand enter that option if you want to use the documentdesigned paper, as in most cases you would. The menuthus seems to be superfluous, but should at any rate havehad the designed paper at the menu head. After this yetanother menu appears asking if you want to proceed withthe printing (as if you didn't) and you have to affirm.
Other functions which now have to be done via a menuare copying, moving and erasing a file. With LocoScript 1these were done by a single keystroke. When setting upthe document the different tabs could be set by individualkeystrokes with LocoScript 1. This too now has to bedone via a menu, and the menu comes right over the topruler, obscuring the tab position. The cursor must there-fore be set to the required position before calling up themenu. This also applies to setting the left-hand margin,which is similarly obscured.
Another extra menu that requires an acknowledgementand can thus be irritating to the careful user, though nodoubt a life saver for others, is the one which warns that afinished document on the M drive will be lost if you switchoff without copying it on to a disc. In view of what is atstake however this is perhaps justified.
More irritating are the messages that appear in windowswhen certain functions are selected. For example, wheninserting text from another source the message "insertdocument: select document using cursor keys then pressenter or cancel to abandon" is displayed. As precisely thesame wording appears at the same time in the header atthe top of the page this message is superfluous. Theannoying bit is that, as with some of the menus, the
window obscures the very part of the screen you want touse. The message clears after a while, but introduces anunnecessary delay. The same thing happens when copyingor moving a document - it didn't with LocoScript 1.
Too Amateurish?The overall impression given by these extra menus and
messages is that LocoScript 2 is less professional thanLocoScript 1, which is rather a pity since in many otherrespects it improves on LocoScript l's amateur image andincludes facilities that rival and excel most professionalword processing programs. The makers clearly felt itimportant to appeal to the beginner and the experienceduser, but in so doing have tended to fall between twostools. One solution would be to issue the disc with thefull existing program on one side and a streamlinedversion on the other. There would be room for this alongwith the tutorial examples that occupy part of this side.
Function KeysThe function keys and their options have been changed.
This has been done mainly because of a rationalisation inthe way in which the functions are classified, but one ortwo seem to have been altered for no apparent reason.Disc change for example is now f7 instead of fl. Tables 1and 2 show the differences. The keystroke codes havechanged little except for a few additional letters.
Setting up DocumentsSetting up document templates and establishing the
layouts is quite different with LocoScript 2. One effect isthat the layouts become part of the text rather than beingstored in the document header. So when the text istransferred or copied on to another document, or adifferent position in the same document, the layout goeswith it. Layouts can also be given names as well asnumbers. The advantages of the new system seem to beminimal, and to make it easier for users I think this shouldhave been left as it was.
ImprovementsMy comments so far seem to have been mainly criti-
cisms. I wanted to get these out of the way beforementioning the numerous improvements that more thanbalance them out.
PaginationI always felt that too much attention was paid to
pagination - the messages you might want to put at thetop and bottom of each page - in LocoScript 1. Apartfrom page numbers this is not an oft -used facility. Yetwhen setting up every document or template you had togo through a pagination routine whether you wanted it ornot. With LocoScript 2 the facility is there but can be side-stepped apart from a display of the pagination boundarylines.
With LocoScript 1 the header and footer zones includedthe top and bottom gaps, the top inch and bottom halfinch on which you cannot print. These had to be allowedfor when calculating the space to be allocated to headers,footers and main text. They are now treated separately, sothat the usable zones can be assigned as required without

in operations between LocoScript 1 and 2. Many options call upof operation such as printing and document set-up which havedisplayed across the top of the page for reference with bothget used to the changes.
PrintersWhile LocoScript 1 can be used with only the dot-
matrix printer supplied, LocoScript 2 can be used with awide variety of printers, of the matrix or daisy -wheel type.In fact you can connect a matrix and daisy -wheel printerat the same time and select from the keyboard which is tobe used for a particular print-out. The supplied matrixprinter gives perfectly satisfactory results however - in thehigh -quality mode the results are not far short of thoseobtained with a daisy wheel. The big advantage with thematrix printer is that an enormous range of characters andsigns, letter styles and sizes is available. With the excep-tion of one or two letters the styling of LocoScript 1 wasgood. The styling of all letters has been revised withLocoScript 2, the visual effect being even better thanbefore.
With LocoScript 1 the printer had to be set for the typeof paper to be used, so this had to be done when creatingand when printing a document. LocoScript 2 has a built-inmemory of various named paper sizes which can heinspected, altered or added to. When a document is to beprinted the printer recognises its paper size from thememory. If it has just been printing another size a menu
tells you that it's not set to the document paper. A singlekeystroke plus enter sets the printer to the required size.If the document is created for a paper not present in thememory the printer will find the nearest listed size andoffer it on the menu.
As A4 is the most commonly used size this is the one towhich the printer is set at switch on. If you morefrequently use another size you can change the memory toselect this instead. This gives you automatic selection ofthe preferred size without a succession of printing menus -after three quick taps on the enter key the printer willstart without further ado.
Page NumberingWhen the page number code is inserted in the docu-
ment set up, page numbering is carried out automaticallyas before. Now though with a long document such as ahook, in which the chapters are more conveniently pre-pared as separate files, the page numbering can be madeconsecutive instead of each file starting at page 1.
Phrases and BlocksAs with LocoScript 1, blocks of text or individual
phrases can be copied out, given code numbers andinserted elsewhere as many times as required by typingthe code. Previously phrases could be inserted into other
TELEVISION MARCH 1989 347
documents but blocks couldn't be unless they were spe-cially saved. Now blocks are automatically saved and canbe used in different documents. If required in the futurethey must still be saved on disc - the internal memory islost when the PCW is switched off.
When it was asked to show what phrases and blockswere stored LocoScript 1 listed just the code numbers orletters. The first few words now appear along with theletters. This is very useful as unwanted or obsolete itemscan be identified and removed to make room for newones.
Find and Exchange
A snag with the find and exchange feature withLocoScript 1 was that the word typed in had to match theone sought exactly. Thus if it sometimes appeared in thetext with a capital initial but you typed it into find in lowercase it would be ignored. If the word also occurred as partof a longer word the cursor would stop at all these too.With LocoScript 2 the find facility has been made moreflexible. If told to do so it will find words irrespective ofcase. It will also find only complete words if so set. Thismakes the feature much more useful.
Cursor MovementOne of the criticisms of LocoScript has been the rather
limited scope for moving the cursor around the screen. Itcan be moved to the next character, word, line, para-graph, unit, page or to the end of the document. Thesemovements can also be reversed to go back through thedocument. This may seem to be a comprehensive list buttwo very useful moves are omitted, from one phrase toanother (stopping at commas or semicolons) and from onesentence to another (stopping at full stops). When correc-tions are made the portions to be erased are usuallyphrases or sentences, so such moves would be veryhelpful. It's possible to use the find facility to locate thenext and subsequent full stops or commas, but if youchange from one to the other you have to reinstruct findaccordingly.
Speeding things upOther word processors permit erasure of a line to the
right of the cursor, to the left of the cursor, or the wholeline under the cursor. With LocoScript you have to definethe portion to be erased by placing the cursor first at thestart and then at the end of the section, operating the cutkey in each position. This is not too onerous if the lineand end -of -line keys are operated to produce quick cursormovement. Some users may get confused about thesekeys and not use them to the full. The line key takes thecursor to the end of the line while the end -of -line key (lineplus shift) takes it to the start of the next line. If pressedwith the alt key the cursor moves to the start of the sameline. It's a pity that these keys were not given lessconfusing designations.
Another tip worth remembering is that a single dab oneither of the horizontal cursor movement keys with theshift key will move the cursor by forty characters, i.e.about half a line to left or right. The vertical keys withshift give movement of forty lines up or down for a singlepress. This is the case with both LocoScript 1 and 2. If youpractice these manoeuvres a few times you soon get thehang of it, greatly speeding your movement around the
text. This makes LocoScript as fast as any other word-processing system.
An aid to speedy movement with LocoScript 2 is thefacility enabling you to select a required page from thestart of a file. The chosen page appears on the screen injust under half the time it takes to scroll through to thepage with the cursor movement key.
CharactersWith LocoScript 2 there are special registers known as
super -shifts to make a greatly enlarged range of charactersavailable. These are entered by pressing the alt key withone of the f numbers 1, 3, 5 or 7. Amongst the charactersobtainable in this way are the complete Greek alphabet inlower and upper case, which is very useful for technicalwriters - LocoScript 1 had just a few. There is also thecomplete Cyrillic (Russian) alphabet in both cases withseveral Ukrainian alternative characters: other speciallanguage characters available include examples from Tur-key and Greenland. A wide range of accent marks can beamalgamated with any letter simply by typing one afterthe other.
A considerable number of textual symbols, includingspecial continental ones, and the symbols for the world'sleading currencies are included. Over seventy mathemat-ical symbols can be obtained, including the one that wasconspicuously missing from LocoScript 1 - the radical orsquare root sign. There are even sixteen varieties ofarrows and, yes, those card symbols and smiling faces!
With such a vast array of characters provided it seemsungrateful to grumble, but it's now harder to get eighthfractions. Thirds fractions are now included however.
Discs
A much vaunted facility with LocoScript 2 is the abilityto format or copy discs with the LocoScript system,though I feel that it's a marginal advantage. It's performedby key 12 which produces a menu of options - copy disc,verify disc, format disc and rename disc. The verify optionis the only omission as far as I can see from the otherwiseexcellent manual. There's no information as to what itdoes - it seems to check whether a disc is properlyformatted.
Editing
What I consider to be a major improvement seems tohave gone largely unheralded. When an existing file isedited you need at least the same amount of space to beavailable as that taken up by the file. This is because theedited version is recorded on a disc before the old one isscrapped. Thus for a few seconds both versions arepresent. If the file is a long one you need plenty of spareroom. It's all too easy to overlook this and withLocoScript 1 the first intimation you have of insufficientspace is when you try to exit and store the resultwhereupon the "disc full" notice appears. There's noinformation or advice in the old manual about what to donext. After two experiences of losing a morning's work Idiscovered how to suspend recording while moving orerasing files from the disc to make room.
When you start an edit with LocoScript 2 the disc isscanned to see if there's enough space. If there isn't, thenotice "warning, document may not fit" appears and theoptions to cancel or continue are given. This is one menu Iheartily welcome! In this situation the easiest course is to
348 TELEVISION MARCH 1989
copy the document to drive M, work on it there, thenmove it back to drive A while erasing the original.
Another very useful new feature relates to the use ofthe same file name. You cannot have two files with thesame name in the same group as the addressing andindexing facilities would be unable to distinguish betweenthem. With LocoScript 1 if you want to replace anobsolete file with an updated one having the same nameyou have to give it a temporary, different name, move itinto the required group, erase the old file then change thename of the new one to that of the old one. Now when anew file is moved into the same group as an old one withthe same name a menu appears pointing out that thename is already in use and offering the options ofreplacement with the new file, choosing another name orcancelling the operation. Choosing to replace erases theoriginal file and instals the new one at the same time. Thisfacility can be used when moving an edited document indrive M back to replace the original version in drive A.I've found it to be a very convenient feature and aconsiderable time saver.
Documents made in LocoScript 1 cannot be printed or
edited with LocoScript 2. If an edit is attempted, the filewill be converted automatically to LocoScript 2. Only thepaper size may need to be reset. Conversion is necessaryonly the first time, after which the file becomes a perma-nent LocoScript 2 document. This means that it cannotafterwards be worked on in LocoScript 1. If you want topreserve that option it's best to copy the document, thenconvert the copy to LocoScript 2, retaining the originalLocoScript 1. All templates should be converted other-wise every document made from them will be inLocoScript 1 format and will need converting. Not all thedetails come out right however: I've found it better toremake all templates in LocoScript 2.
ConclusionSo much then for the main differences between
LocoScript 1 and 2. I feel less than enthusiastic aboutsome of the changes and am disappointed over theomissions, but the fact remains that it's an excellent word-processing system. The many advantages over LocoScript1 clearly outweight the drawbacks.
Compact Disc System DevelopmentsSome interesting technical details of the Philips CD -Videosystem were presented at a recent talk at the Institution ofElectrical Engineers. The lecturer was Simon Turner,head of the Home Interactive System Division of thePhilips Research Laboratory, Redhill. His talk, entitled"Voice, Data and the Compact Disc", started with ageneral view of the evolution of CD technology from itsbeginnings at Eindhoven in 1969. Since the launch of CDdigital audio in 1982 thirty million players and 450 milliondiscs have been sold worldwide (eight per cent of UKhouseholds own a player). CD audio has been called thefastest -growing consumer electronics product: its successhas been helped by the common standard, which ensuresthat all discs can be played on all players.
CD -VideoCD -Video is now in the shops. It combines digital audio
with analogue video on the same disc. The standard 5in.CD -Video disc (gold coloured to differentiate it from itsaudio counterpart) contains five minutes of video withdigital sound on the outside of the disc and twentyminutes of digital audio on the inside. A single laser headreads the sound and vision signals simultaneously. Thevideo signal is handled in the same way as withLaserVision: the PAL signal is modulated on to a 7MHzcarrier with the baseband digital audio underneath - ittakes up about 2MHz. The digital audio portion of the5in. disc can be played on an ordinary CD player.
CD -Video players can take any size of disc up to 12in.(a 3M. disc is planned). LaserVision discs are compatible- most players can handle an analogue sound track.Setting up of the required tracks is done on the TV screenwith the remote control unit.
CD -InteractiveThere's no transatlantic compatibility with the analogue
video signal, which is a drawback. It will limit the choice
Peter Marlow, B.Sc. (Hons.), C.Eng.of CD -Video discs, or software as we have to call them.This however is not the case with Philips' next develop-ment, CD -Interactive. CD -I is being planned with thedomestic market firmly in mind. Audio, graphics, dataand video are stored on the same disc, with the differencethat this time the video is digital. This makes for truecompatibility between TV standards. The pixel standardsare 384 x 280 for normal pictures, 768 x 280 for doublesize and 768 x 568 for "extended" studio -quality pictures.For most applications the video consists of stills, butmoving effects such as a talking head within a stationaryframe can be generated. The recording techniques arevery much related to computer images rather than TV.However the picture display will always be via a TV setrather than a computer monitor as CD -I is seen as aprimarily domestic product.
The first CD -I players are now being demonstrated. Atpresent they consist of two boxes, the CD player and theMMC (Multi -Media Control) module. The latter links theplayer to the TV set and hi-fi system and is operated byremote control. The remote control unit incorporates apointer control for on -screen selection. The hardware isbased on a 68000 microprocessor which runs the OS -9operating system. A dedicated piece of hardware is usedfor file handling, though the data transfer rate is fairlyslow at about 150kbytes/second. It shouldn't be too longbefore the two boxes become one!
The CD -I players will not sell unless there's goodsoftware for them, i.e. plenty of discs to go with them. Tothis end Philips has set up a company called AIM(American Interactive Media) which is linked withPolygram. Two other similar companies are being set upin Europe and Japan. The main applications envisaged areinteractive talking books, educational aids and superioradventure games. Replication cost is small, but the datagathering and setting up is an expensive and time-consum-ing business. No doubt Philips will be supplying develop-ment tools to make it as easy as possible to exploit thisinteresting new technology.

If it's overheating, theloading motor is drawing excessive current. Depending onhow many goes the user has attempted, the motor drivechip IC3005 (BA6238A) may or may not havesurvived. E.T.

We've encountered the following situation on more thanone occasion: the capstan motor starts running at switchon then after a few seconds the syscon switches thecamcorder off again. The cause is that the 9V supply tothe main PCB is missing - check at TP1002. You'll findthat the circuit protector fuse PR1002 is open -circuit. Thisseems to happen for its own internal reasons, since we'venever found that excessive current has been flowing andhave never had a replacement fuse fail. E.T.
Sony CCD-V100
Since the same accessories are used, the design andpinning of the recessed multi -output plug on this model isthe same as for the CCDV7/8/AF range. Even though thereadily -conductive metal caps are omitted from the locat-ing pins with the later production r.f. unit, clumsy inser-tion of the modulator can bend and short-circuit thedelicate connection pins. Thus whenever the main 3.15Afuse inside the camcorder has blown, carefully examinepin 3 of the multi -connector for signs of arcing or burning.Unless the pin is broken or badly bent, the fuse (in thismodel F381 on board SC -6) is the only casualty.

Grundig VS180
Grundig VCRs are rare visitors to our workshop. This onewas said to be stuck in pause. What happened was thatthe machine would have a brief go at any functionselected and would then shut down with the pause LEDalight. This is an "emergency" indication, drawing atten-tion to lack of reel sensor pulses, and in this case came on
Reports from Philip Blundell, Eng. Tech.,Eugene Trundle, lan Bowden, Alfred Dampand Nick Beer
because the reel brake solenoid didn't operate. A pull -incurrent is routed via a switch (behind the solenoid) whichopens when the armature has moved over. Its contactswere dirty, leaving only the hold -in current in the sole-noid. Giving the switch contacts a good clean restorednormal operation. E.T.
Hitachi VT410
Many customer descriptions are merely the first clue inthe guessing game that occupies an engineer during thefirst part of his diagnostic session. "Sound slurs" is one ofthe better ones, usually indicating problems in the capstandepartment. On this machine the capstan ran slowly anderratically. A meter connected to the speed control line tothe motor showed that the servo was working flat out tospeed up the motor. The motor itself was faulty, though itran very freely when turned by hand. E.T.
Fisher FVH-P710
If you find that fuse F902 (500mAT) on the mainstransformer PCB has blown for no apparent reason, checkfor dry -joints at the PCB connections of pins 10 and 12 ofconnector PV903 on the regulator panel. Considerablecurrent passes through these pins, and some of it will bediverted through F902 and C928 in the event of amomentary open -circuit. The other joints on the plug/socket connections to this board are also worth checking.

The fault with this machine was no colour. Use of anothermachine proved that it was recording the chroma signal,so the fault was only on playback. From the headamplifier circuit the chroma passes to the playback pro-cessing circuitry via a couple of filters. There was an inputto the first filter LPF201 but no output. As a check, thefilter was removed and an 0.1/2F capacitor was used tocouple its input and output connection points. This re-stored colour, so a new filter was ordered. I.B.
Ferguson FV20There were two fault symptoms with this machine, noplayback picture (blank screen, sound o.k.) and whatlooked like a low luminance level in the E -E mode. Bothproblems were caused by the same faulty component,low-pass filter LPF102 which is connected between pins 10and 21 of IC101 and is used for both E -E and playback.

Sound but no playback picture was the reported fault withthis machine. From this description I suspected cloggedvideo heads, so before trying a tape I took a look at them.There was some oxide present, but it wasn't too bad. Thedrum was next warmed to remove any moisture and atape was played back. The picture was fine! It was onlywhen I moved the luminance/chroma board - I had to foldit up to the vertical position to remove the video head

screening can - that the fault occurred. The effect wassimilar to an off -tune monitor TV set - just off the higherend of the r.f. output. The fault could be made to comeand go by slightly twisting the panel. Close examinationrevealed a dry -joint on a small luminance coupling capaci-tor (C134) which is next to the right-hand subpanel. I.B.
Philips VR6362
This machine came in with a broken cassette lift and thecomplaint of no rewind or reverse picture search. In factwhat happened was that when the VCR entered therewind mode the tape tightened and was then unloaded.The drive coupling, item 214, was at fault. A.D.
Akai VS112
This machine would play back prerecorded tapes butthere were no E -E signals and the channel indicator LEDsdidn't light. The LEDs and the tuning potentiometers had33V on all sides, includng the chassis connection. Whenwe traced the earth return back to the main board, viaconnector P601, we found that an earth tag on the tunerunit was dry -jointed - the tuner's case is used as a link tothe earthy side of the tuning presets. We decided toresolder all four mounting lugs on the tuner as well. A.D.
Sharp VCA100
The capstan motor in this VCR refused to work. Wefound that the 15V and 5V supplies were present andcorrect and that the 2.5V reference voltage was correct,but the capstan drive voltage was low at 1.5V instead of2.4V. The capstan stop signal at pin 57 of the systemcontrol chip IC827 was then found to be permanently low.When this monster chip was replaced the capstan motorworked correctly. A.D.
Hitachi VT33
This VCR generated a noise in most modes. The symp-tom was similar to that produced by a dry capstanflywheel bearing in the later VT64 series. As suspected,the flywheel bracket was fitted with the nylon bearing.Further pushing, prodding and listening revealed that thenoise was coming from a pulley on the clutch assembly,item 301. A.D.
Ferguson 3V30
The rather unusual complaint with this machine was nosound in the E -E, record or playback modes. We soonfound that the 10.5V supply to the audio section was waydown at only 0.344V. There was no excessive loading andit turned out that the regulator transistor Q17 was open -circuit. It's a 2SD636 but we fitted a 2SD637 (60Vversion) as this is a much used device we stock forPanasonic VCRs. N.B.
Panasonic NV-100/NV-10B
The problem with this portable VCR and tuner/timercombination was failure to record. On test we found thatthere was no sound or vision in the E -E mode - only thetest signal could be produced. Playback direct from theVCR was fine. A look at the V10 unit was thus required.As the test signal was present that path from P7002-3 waso.k., including the thick interconnecting lead. There wasno video output from pin 2 of IC701 (BN5115). It was
present at the base of 0733 but not at its emitter. When itwas tested we found that Q733 (2SC945/BC547) wasshort-circuit collector -to -emitter. The sound was mutedbecause of the no video signal problem. The NV100 wasthen cleaned, and after replacing the noisy transmissionpulley and belt it too performed perfectly. N.B.
Panasonic NV -G25
After a recent repair the customer complained that theclock/counter display faded out. Our field engineer (wecall him Enid Blyton because of the fairy tales he tells usabout the faults he sees) said he'd seen the fault. Aftermany hours on soak test the display went dim, the finaldigit of the counter being even dimmer than the rest. Theheater voltage was correct but the grid drive was in-correct. The drive comes from the MN15283VJU timerchip IC7501. Replacing this restored correct operation.

A couple of faults are becoming very common with thesemachines. First is intermittent failure to eject, or otherintermittent mechanical faults, caused by a loose earthingscrew on the mecha connection PCB. The other is inter-mittent going into rewind from play during a tape. This iscaused by dry -joints on the supply photosensor. Bothfaults can he exceptionally intermittent. N.B.
Panasonic NV366
A fault you may be faced with in these machines is thechannel one LED flashing and inability to change chan-nels. This can very often arise after replacing the threegold memory back-up capacitors. If you remove these bytwisting them off the board (as you should if they areleaking) you can break R7693 (22k0) in half, producingthe new fault. N.B.
Panasonic NV2000
This one came in with no comments under "fault" on thejob card - always a bad sign! After switching it on thefirst fault noted was that the machine didn't switch fromE -E to V -V. This was because the EXCEPT REC 9Vsupply was missing, soon traced to Q6043 (2SA719) whichhad a 4.7k11 collectoremitter leak. Next the drum speedtook about forty seconds to settle down. Adjustment ofthe drum free -run control took care of this.
I then decided to refuc the two main panels to the metalframe, which was hanging around them loosely as some-one had removed all the screws. I'd previously noticedthat three out of seven chassis fixing screws were missingand bolts were fitted where there should have been screwsand vice versa. Next I found that there was no colour inthe playback mode - the chroma reference set trimmerhad been "graunched '. A replacement was fitted and setup within minutes, but the a.f.c. also had to be realigned-a twiddler had been at large . . .
We're not through yet: there was no sound in E -E orplayback because the REC 9V supply was permanentlypresent, due to 06041 in the syscon being short-circuit.When all this had been put right and the whole thing hadbeen reassembled correctly the machine worked well. Thecorrect screws were fitted! I hope the idiot responsible forputting the deck in this state is reading this and isthoroughly ashamed of himself. N.B.

Dish Alignment by BBC Computer
The following program for use with the BBCmicrocomputer has been written to help satellite TV aerialfitters to determine the azimuth and elevation angles fordish alignment at a particular site. Many articles on thesubject have appeared over the last three years, but thedata given usually applies for only major cities. This pro-gram should provide the required data for any satellitevisible from the UK, at any location, provided the longitudeand latitude are known - this information can be obtainedfrom an Ordnance Survey map.
When the program is run a menu listing a number ofsatellites appears on the screen - see Fig. 2. If required thislist can be changed between program lines 1,390 and 1,640.When the satellite is not listed option number seven en-ables its longitude to be entered.
Use
The program is "user friendly". An example of a typicalcalculation, in this case for the Astra satellite, is as follows:
(1) Select Astra from the menu by entering number six(without pressing the return key). The screen will clear andthe satellite's position, "19.2 degrees East", will appear atthe top of the screen.
(2) A prompt at program line 520 requests that the longi-tude of the receiving site is entered. In this example the siteis Land's End, which is longitude 5-75°W. Enter the number5.75 then press the return key. Prompt line 560 will thenrequest that E for east or W for west of Greenwich isentered. Type W but don't press the return key.
(3) The final prompt at line 630 requests the site latitude tobe entered. Type 50 and press the return key.
The elevation - the angle at which the front plane of thedish has to be tilted back with respect to the vertical - isthen displayed on the screen. In this example it's 27.972°.
The azimuth angle is calculated and displayed in degreesof rotation from true north and also as an angle east or westof true south. As can be seen (Fig.3) the azimuth bearing is148.728° from true north, which is 31.272° east of truesouth.
It's important to know the geographical location in de-grees and decimals, not degrees and minutes. To convertminutes to decimal, divide by 60. For example, thirtyminutes is equal to 30/60 = 0.5°. Note that longitude asdrawn on Ordnance Survey maps is with respect to "gridnorth". This must be converted to true north: the conver-sion constant is shown in the map's legend.
Before the dish can be pointed east or west of true southit's necessary to find true south. A compass needle willpoint to magnetic north and the correction angle can be
J.T. Beaumont
found from the latest edition of an Ordnance Survey map.For Land's End the magnetic variation is currently 8°W.Once the magnetic variation has been found azimuthcorrection can be applied. Subtract the variation fromazimuths east of south, add it to azimuths west of south. Arough indication of true south in the UK can be found bymounting a vertical stick on a flat surface and noting theshadow produced by the sun at 1200 hours GMT (noon).
If you wish to change the satellites listed in the menu(options 1-6), the latitude in degrees is held in variable thetaand E or W of true south (Greenwich meridian) in variableA$ (lines 1,570-1,620).

December provided a relatively quiet close to the year,reflecting the conditions during much of 1988. Sporadic Ereception wasn't wonderful except for early June whenover a three-day period ch. A2/3/4/5 signals from NorthAmerica were seen in the UK and identified as coming
along the eastern Canadian/USAseaboard. There was also a remarkable lunchtime periodwhen North African Band III signals were seen in the UK- in the lower half of the band. Conditions in lateOctober/early November were lively, with increasing sun-spot activity and ch. E2/R1 reception from deep intoRussia and the Middle -Far East. Since then F2/TE recep-tion has occurred from time to time when the m.u.f. hasrisen into the lower end of Band I.
December's log has a little of everything. SpE had itsmoments as follows:
4/12/88 ORF (Austria) ch. E2a; RAI (Italy) ch. IA.5/12/88 NRK (Norway) E2.6/12/88 TVE (Spain) E3; RAI IB.7/12188 TVE E2; 3.9/12/88 SVT (Sweden) E2; NRK E2.

on chs. R1, 2, 3.24/12/88 TVE E2; NRK E2, 3.30/12/88 SVT E2.31/12/88 SVT E2.
On the 16th an aurora was observed, with disturbancein Band I. There was improved tropospheric propagation
on the 11th, with mainly West German Band III/u.h.f.and Danish Band III signals received in central/easternUK. The 22nd produced several Swiss Band III and manyWest German Band III signals. January 2nd/3rd gave W.German/Benelux reception and ducting on the 2nd pro-duced Danish Band III signals in the midlands.
There was lively meteor activity during the month withthe Geminids shower. Tim Anderson logged SWF (W.Germany) ch. E7 on the 12th during this event, thoughthere was naturally much activity in Band I - sufficient toprove the efficiency of the Les Wallen 49MHz helicalaerial!
F2 activity has unfortunately been at a low level. TimAnderson received what he believes to have been Malay-sia ch. E2 between 0825-0923 on the 23rd, at levels to P4.The programme content was western with subtitles ofIndo-Chinese origin. During this time Finnish radio ama-teurs were in contact with their Australian counterparts inthe 50MHz band. The next morning (24th) producedweak, scanner -level sync information on chs. R1, E2 andE3. With the m.u.f. rising to 50MHz, American amateursare commonly reporting reception of ch. R1/E2 videoinformation. On the 20th for example very high level ch.E2 signals were received for some four hours in Canada,though there was only weak backscatter here in the UK.Hugh Cocks in Portugal reports that Brazil ch. A2 andAfrican ch. E2/3/4 signals are received almost daily -signal propagation is mainly by late afternoon/eveningTE. One pointer for transatlantic reception is a broadcastlink now operating in Columbia at 45.7MHz. The RSGBVHF/UHF Newsletter reports that transatlantic openingsat 50MHz were frequent during November/December.Unfortunately the TV bands start at a lower point in thespectrum in Europe than in America, where the lowestchannel is A2 (55.25MHz), so the m.u.f. really has to risefor transatlantic TV reception in Europe.
Anthony Mann (Perth, Western Australia) reports F2/TE reception from China/Malaysia, with some SpEenhancement over the final path. What is of importancefor the record books is the news that Brian Clark, a TV/FM DXer in Auckland, New Zealand, received thefollowing transmissions on October 4/5th: Cairns 4ABC-FM at 105.9MHz, 80kW, a distance of 2,260miles;Mackay ABMQ-4 TV, 100kW, at 1,900miles;Rockhampton 4ABC-FM at 93.7MHz, 50kW, 1,700miles; and Brisbane f.m. and ch. A10 TV at 1,400 miles!
During the tropospheric opening on the 22nd a scram-bled System B ch. E8 TV signal was noted, possibly fromRTB-F (Belgium) or ARD. Can anyone comment onthis?

The RSGB VHF/UHF Newsletter suggests that thepresent sunspot cycle, no. 22, will peak late this year witha smoothed count of around 180. This would represent thesecond best since records began. The last peak of around165 in 1978/9 produced signals reaching to about 60MHzover long F2 paths. In the late fifties cycle no. 19produced a smoothed count of around 200, so things lookgood for us later this year!

Meteor Shower/Scatter PropagationFrom time to time in this column we describe for
newcomers the basic signal propagation modes that makelong-distance reception possible. This month we'll con-sider meteor shower/scatter propagation.
When the E layer of the ionosphere, about seventy milesabove the world's surface, is sufficiently ionised v.h.f. TVsignals can be reflected back to Earth, giving long-distancereception at up to say 1,200 miles from the transmittingsite. Sporadic E propagation occurs when patches of theionosphere become intensely ionised. This happens mainlyduring the summer months, when SpE openings canproduce high-level, long -duration signals in Bands I -Ill. Asimilar phenomenon is caused by meteorites that enter theionosphere. When they reach the E layer they burn up andvaporise, producing ionisation sufficient to support signalreflection. Such ionised areas lie in trails along the paths ofthe decaying meteorites. The ionised trail is relativelysmall, and as a result the distant reception site will have anarea of only about six miles by twenty five miles. Thus asignal received by one DXer via this mode may well not bepresent at another DXer's location perhaps twenty milesaway. This second DXer may receive a signal of minimalstrength or perhaps a signal from a different transmitter.
Meteor scatter propagation works best with Band Isignals. Higher frequency signals can be reflected by veryhigh density trails - Band III TV signals are reflected attimes, particularly during the regular meteor showers, butin Band III the signals are of short duration and infrequent.
It's interesting to note that military communicationssystems exploit the random MS trail phenomenon forregular data communications, using digital techniques. Inmodern duplex systems a continuous probe signal isradiated. When the intended receiving site detects theprobe signal an acknowledgement is sent back to thetransmitter which then sends out a digital burst signal alongthe MS reflection path. The ionisation density lasts longenough to support reflection for between half a second to aminute. According to military information a data rate of ahundred words a minute can be averaged over a 24 -hourperiod. In the USA information on snow levels and otherweather data is transmitted via the MS SNOTEL system,and in Alaska military information from remote radar sitesis transmitted via MS propagation. There is particularmilitary interest in MS propagation since a nuclear strikecould cause disruption of h.f. communications through E/Flayer destruction.
MS propagation makes DX -TV reception possiblethroughtout the year, though the duration of the signalsreceived will be short, ranging from "pings" of a second orso to "super pings" that give reception for approaching aminute. One problem with Band III MS reception is thatDX aerials tend to be of the multi -element type, withreduced vertical capture.
Apart from daily random MS activity there are periodsof intense MS when the regular meteor showers occur -the main meteor shower dates for 1989 were listed in theJanuary issue (see page 208).
For MS DX -TV reception the receiver must have veryfast sync action since the signals may last for only seconds.Many of the signals are weak, so aerial gain and a low -noiseamplifier are necessary. Accurate tuner calibration isessential. The early morning hours tend to be best for MS,though results depend on the transmitters that happen tobe on air at the appropriate time - with increasing"breakfast TV" in Europe, Band I MS reception is thesedays a lot more common than it used to be.
Radio Amateur Operation at 50MHzThe RSGB reports that Dutch radio amateurs have
been given permission to use SSB transmission at 50MHz- formerly only c.w. had been permitted. Some 420applications for permission to operate at 50MHz havebeen received by the French authorities. Strict operatinglimits are in force to prevent interference to ch. L2 TVtransmissions. Over 100 permits have been issued to date.50MHz operation was considered in Luxembourg butapparently there have been interference problems withcable systems. The Danish authorities have not yetreached a decision on 50MHz operation. Twenty fiveexperimental permits have been issued in Sweden, allow-ing operators to use 50W e.r.p. for stations 250km from ach. E2 transmitter and lower powers at closer distances.Cyprus has extended 50MHz operation. Farther afield, atleast one UK amateur is operating at 50MHz in Nigeriaand a further amateur is operating in the Falklands.
The 50MHz amateur band has caused TV-DXers fewproblems to date - unless you happen to live within a fewmiles of an operator, when ch. E2/R1 reception canbecome difficult. The problem is not as bad as a nearby49MHz baby alarm however. We understand that DaveLauder is working on a new notch filter design with a verysharp response to help with rejection of adjacent sourcesof interference and hope to be able to pass on moredetails shortly.

TANDBERG CTV3 CHASSISThis set trips continuously and although the feeds from thepower supply and the line output stage have been discon-nected I cannot isolate the cause. The power supply panelhas been checked for dry -joints and various smallersemiconductor devices have been replaced. With the 160Vline isolated from the main panel the h.t. pulses up toabout 80-90V. The 12V supply to the TBA920 chip is alsolow and pulsing. Obviously the overvoltage trip is notoperating or the fuse would blow.
It sounds as if the excess current trip is operating. Firstcheck that R754 (0.4751) hasn't increased in value, thencheck Q736 (BC548). To prove that the line output stageetc. isn't loading the power supply excessively, wire a60W, 240V bulb across the main output from the powersupply.
SONY SLF30This machine plays prerecorded tapes all right but its ownrecordings produce a picture that is grainy for a second ortwo then a good picture with wow on the sound, as thoughthe speed is varying. The fault is the same when the tape isplayed back on another machine.
The cause of the trouble could well be poor transfer ofthe control track pulses - clean the control track head. Ifthis doesn't cure the problem, try setting up the capstanservo. If difficulty is experienced in doing this check thecapstan shaft bearings for free running.
BUSH BC6004There's no vision or sound - even the tube's heaters areout. The supply into the set is all right but it seems to usesome rather unusual circuitry.
This set was produced by Saba and uses a combinedline output/power supply regulation arrangement called aWessel circuit. Check with an ohmmeter whether T686(BU208) or D687 (SKE4F/10) is short-circuit. If they areo.k., check for 300V at the mains rectifier's reservoircapacitor C858. If this voltage is missing the surge limiterresistor R854 (6.851, 11W) is probably open -circuit. If it'spresent the protection circuit associated with thyristorThy697 could well have come into operation. Investiga-tion of this calls for the use of a variac and oscilloscope.
GRUNDIG 2 x 4 SUPERWhen picture search is selected, in either direction, thepicture rolls continuously. Occasionally the picture locksfor a split second. When this happens the picture is good.
This affect is usually due to need for tape servoadjustment. This should follow a check on video headheight offset - a dual -beam oscilloscope is required forthis. Servo adjustment also requires an oscilloscope and a
method different from that described in the manual -refer to page 76 of the Grundig Technical Bulletin issueno. 5, 1983 (part no. 00(02-360.05).
FERGUSON TX90 CHASSISThis is one of the 14in. models. The fault is a thin whiteline rising from the bottom of the picture. Sometimes thereare two such lines.
We suggest that you check the 95V supply decouplerC191 (22µF), then D107, 8203 (33SZ) and TRIOS(TIP112H) in the field output stage before suspecting theexpensive TDA4500 chip. Use of gentle heat from ahairdryer and a freezer aerosol may help to pinpoint thefaulty component.
PANASONIC NV788The heads were replaced using genuine Panasonic parts.The result: excellent standard play operation, along withslow-motion effects etc., but on long play the picture is verynoisy, as though one head isn't functioning. Inspection ofthe f.m. envelope waveform showed that the output fromone head is about half that from the other one. A secondset of heads has made no difference.
The heads have separate preamplifiers - IC3502 catersfor LP operation. Suspect it once you've proved that thetracking is perfect in the SP mode and that the drives tothe bases of Q3501 and 03502 are correct.
GRUNDIG CUC720 CHASSISAfter fitting a new tube the picture was found to be off-centre vertically, by about 5/sin. (too high). The problem isthat there's no field shift control. All the controls availablework normally.
The tube tolerances are such that with correct setting upthe picture should be within a few mm of the correctcentring. The purity adjustment has the biggest influenceon centring. The other c.r.t. neck rings also affect it.These items should be adjusted.
FERGUSON 3V48We have the same trouble with two of these machines. Thefault is with hi-fi audio and occurs with both own record-ings and prerecorded tapes. Intermittently a slight buzz/crackle is heard on both channels, for approximately a halfto a second. This can happen every ten seconds or not beheard for about five minutes. AU the relevant adjustmentshave been carried out. If a scope is connected anywhere inthe playback circuit a ripple can be seen when the noise ispresent. Slight pressure on the deck produces a similarfault but slight adjustment of the entry/exit guides onlymakes matters worse.
IC204 could well be the culprit. Apart from this a gooddeal of information on the problem was published in issueno. 29 (February 1987) of Ferguson Feedback.

HITACHI CRP143 (NP6C CHASSIS)Sound and picture are periodically lost. After switchingoff, sometimes for an appreciable period of time, every-thing is o.k. when the set is switched on again. Anysuggestions?
First check the soldered joints around the choppertransformer T902 and the line output transformer T703,preferably by disconnecting them then resoldering. Ifnecessary replace the voltage divider/reference source unitCP901 (HM9102) and the error amplifier transistor TR907and check all associated joints. Occasionally rectifierdiode CR705 (VO9C) or R733 fails, killing the 12V line.
I MOCASE
315Each month we provide an interesting case of
TV/video servicing to exercise your ingenuity.These are not trick questions but are based onactual practical faults.
David the Downtrodden was about to leave the yard onthis bitterly cold morning. Out of his warm den theService Manager trotted with a further job in his hand.One more in Crowfield - a rental Toshiba VCR with a"poor picture". What does a "poor picture" mean?Anything! Why can't the hens in the office get morespecific details?
David arrived to find a Toshiba Model V66 (similar tothe JVC HRD140, Ferguson 3V44 etc.). He was told thatthe playback picture was "wobbly". His own test tape,with a recording of the IBA test pattern, was inserted andthe playback picture on the TV screen was then exam-ined. The picture showed a lateral twitch effect, withwatery verticals, especially in the lower part of the screen.This can arise from incompatibility with the TV set, butthe one installed was correctly set up for VCR use -indeed the off -tape picture was considerably worse whentuned in on one of the off -air channels. Just to make sure,another TV set from the van was brought in and hookedup. The results were exactly the same. Anyway, TVcompatibility problems usually cause a twitch at the top ofthe screen rather than the bottom.
David cleaned the lower drum, the capstan, the pinchroller, the guides and the head drum cylinder. This did notimprove the playback pictures, and a recording made onthe machine showed that the jitter effect was even worse!On to the van with the machine then.
With the VCR in the workshop the symptom wascarefully studied and analysed. It was plainly due totiming jitter in the playback signal - the effect of minutechanges in the speed at which the recorded tracks werebeing scanned. This can arise from irregularities in thetape's progress or in the head drum's peripheral speed.
The second possibility was investigated first. The drumwas carefully rotated by hand, while "feeling" and listen-
ing for any roughness or rumble in the bearings. None wasapparent. A scope was next hooked to the drum motor'serror control line. The ripple level here was found to beno higher than in a similar model whose playback picture.was o.k. Could it be that the head motor, a direct -drivetype, was faulty? Perhaps the only real test for this is bysubstitution, so at this stage we decided to investigate thealternative possibility, tape judder.
The entire tape path was again cleaned and polished,and the lkHz tone from a test tape was listened tocarefully for signs of flutter. No clues emerged from thesesteps, or from a check of head eccentricity with animprovised mounting for the gauge. The running of theimpedance roller (beside the full -erase head) was nextchecked. When spun fast it rattled and roared somewhat.Could this be the cause of the trouble? A single drop oflight lubricant was run down its shaft, after which it ran assweet as a nut. The playback picture was no betterhowever!
Workshop Sage was consulted on the matter. The factthat the jitter was worse in the lower part of the pictureseemed to him to be an important clue. With no tape inthe machine he prodded, poked, felt and listened. Hethen loaded a test tape into the machine and, whilewatching the TV screen, applied a miniscrewdriver tip to acertain part of the deck. This had some effect on thejittery picture. Sage suggested a possible culprit, a smallbut high -precision component, which did indeed turn outto be the cause of the trouble. What was it? See nextmonth's issue for the answer.
ANSWER TO TEST CASE 314- Page 284 last month -
An incredible set of symptoms was present in thePanasonic NV7200 VCR described last month. Inplayback the machine behaved exactly as if a blank tapewas loaded, except that there was sometimes a snatch ofsound and vision at the beginning of the playback and thatthere were good pictures in the review mode provided thetape being reviewed hadn't previously seen an attempt atplayback in the machine!
The machne was of course "reading" blank tape in theplayback mode. As the tape approached the video headdrum it was being erased by the full -erase head, whichwas operating even during playback. Thank goodness thealignment tape hadn't been fed into the machine at anystage!
Normally the full -erase head comes into action onlywhen the machine is in the record mode. The eraseoscillator is switched on by a voltage at pin 3 of P4001.This voltage turns on switching transistor Q4019 on the Y/Gaudio panel. When tested this "relay" transistor wasfound to have developed a virtual short-circuit, with theresult that the erase oscillator was powered at all times.
During the testing and head -scratching in the, workshopthe rogue machine had wiped clean sizeable portions ofsome of our favourite tapes, and had done the same tosome of those belonging to the owner. The worst newshowever was for the proprietor of the video rentalshop . . .
