THE ANTIQUE RADIO AND PHONOGRAPH NEWS NOW NAMED:
Wireless Telegraph Oddities BY SIGNOR GUGLIELMO MARCONI.
(187411937).
"On Nov. 27, 1901, I left for New- foundland with two , assistants. As ít was impossible at .that time of the year to set up a permanent installation with poles, I decided to carry out the experi-, ments by means of receivers connected. to elevated wires supported, by balloons or , kites-a 'system which I had ,previ- ously used when conducting tests across the Bristol Channel for the British Post Office in 1897.
"It will be understood, however, that when it came to flying a kite on the coast of Newfoundland in December, this method was neither an easy nor a com-
5908
fortable one. ' When the ' kites were got up, much difficulty . was caused by the variations of the wind producing con-. stant changes in the angle and altitude of the wire, thereby causing correspond- ing variations in its electrical capacity and period of electrical resonance.

off the Record. The mechanical :system of recording "cute the records
with a style of sound that has a beauty of its own person--. alitye The. picture and text below, which describe the mechanical system should be interesting to The Horn Speaker readers., who are not familiar with the old method of re- cording sound or refreshing to record enthusiasts, who are familiar with the. method'..

How RECORDS ARE MADE FOR THE PUBLIC
Although the principle of the phonograph is now well known, the art of making records is deliberately shrouded in mystery. The particular composition of the wax-!ike "master" employed by a manufacturer is kept a profound secret. Few "outsiders" are permitted to see even the making -of a record-certainly no one connected with a rival company. The proceeding is complex and calls for much skill, technical knowledge, and experience.
Imagine a great tenor, a popular operatic idol, about to immortalize his rendering of Verdi's "Celeste Aida." Before him is the mouth of a horn; behind him the orchestra. Even he does not see the actual recording equipment; for the small end of the horn is located either behind a curtain or a partition. The musicians are poised between heaven and earth, for some of them sit on shelf -like benches, so that their heads are not far from the ceiling. So cramped are the quarters that often they assume positions at which a concert audience would gasp in amazement. For example, the trombonists sometimes turn their backs to the conductor; they follow_him by keeping their eyes glued on mirrors by which his expressive beating of time is reflected: The loud instruments-the ponderous brasses-

"My assistants at Poldhu, in Cornwall, England, had received instructions to send on and after December 1'1, during certain hours every day, a succession of .'S's' followed by a short message, the whole to be transmitted at a certain pre- arranged speed every ten minutes, alter- nating with five minutes' rest.
"On December 12 the signals trans- mitted from Cornwall were clearly re- ceived at the prearranged times, in many cases a succession of 'S's' being heard distinctly, although, probably in con- sequence of the weakness of the sig- nals and the constant variations in the height of the receiving aerial, no actual message could be deciphered.
"The following day we were able to confirm the result. The signals were actually read by myself and by my as- sistant; Mr. G. S. Kemp.
"The result obtained, although achieved with imperfect apparatus, was sufficient to convince me and
, my co-
workers that by means of permanent stations-that is, stations not dependent on kites or balloons for sustaining the elevated conductor-and by the employ- ment of more power in the transmitters it would be possible- to send messages. across the Atlantic Ocean with the same facility with which they were being sent over much shorter distances.
"About two months later, in Febru- ary, 1902, further tests were carried out between Poldhu and a receiving station on board the American liner Philadel- phia en route from Southampton to -New York. The sending apparatus at Poldhu was the same as1 that used for the New- foundland experiments. The receiving aerial on the ship was fixed to the main- mast; the top of which was 6o meters (197 feet) above sea level.
"As the elevated conductor was fixed and not floating about with a kite,. as in the case of the Newfoundland experi- ments, good results were obtained on a syntonic receiver, and the signals were all recorded on tape by the ordinary Morse recorder.
"On the- Philadelphia readable mes-
nate from the sun are largely absorbed in the upper atmosphere of the earth, it is probable that the portion of the earth's atmosphere which is facing the sun will contain more ions or electrons than that portion which is in darkness, and therefore, as Prof. J. J. Thomson has shown, tnis illuminated and ionized aír will absorb some of the energy of the electric waves.
"The, fact remains that clear sunlight and blue skies, though transparent. Ito
light, act as a' kind of fog to powerful hertzian waves. Hence the weather conditions prevailing in this country are usually suitable for long-distance wire- less telegraphy.
"The operation of the long-distance stations in England and America made it possible to transmit messages .to ships, whatever their position, between Europe and North -America, and to the Cunard Company belong the credit of having greatly encouraged the long-distance tests, a circumstance which enabled them to commence, in- June, 1904, -the regular publication on their principal vessels of a daily newspaper, containing telegraphic messages of the latest news from Europe and America. .
"This daily newspaper has now been adopted -by nearly all . the large liners plying to New York and the Mediterra- nean, and it obviously owes its entire ex- istence to long-distance wireless teleg- raphy.
"In some of my earliest experiments in 1896'I used copper mirrors, by the aid of which it was possible to project a beam of. electric radiation in a certain direction, but I soon found that this method would only work over short dis- tances.
"About three years ago I ' again =took up the subject, and was able to deter- miné that by means of horizontal aerials, disposed in .a particular manner, it was possible to confine. the effects of electric waves mainly to. certain directions as dé - sired.. True,' the 'limitation of transmis- sion to one direction is not very sharply defined, but it is nevertheless very useful.
"The practical result of this method has , been so far that messages can be sent, over considerable distances in the

In a display of vintage radios the "Kennedy" model VI will assert itself like a lily among sundry flowers. The half-. exposed tubes and the gold plat- ed trim shine on the simulat- ed wood panel in gleaming splendor.
The model VI is seldom seen in collections, making it a rare receiver. It is difficult to locate a picture of it, unlike the model V, in old radio magazines. The only place I have been able to find an old illustration of it is in the March 1925 Radio Na=:'s Radio Set Directory.
This radio has the dist- inction of having three stages of audio amplification. How often anyone ever pushed the the speaker plug into the last stage jack would be interest- ing to know. In the model VI, I operated, the last stage of amplification was high in dis-' tortion, which vas a symptom that discouraged most set manufacturers to try three stages of amplification.

The tenor soars up and down the scale directly into the yawning mouth of the horn. He gives his full- throated best; for he knows not only that his .rendition of "Celeste Aida" will be heard by thousands, perhaps by millions, but that the luscious . top notes, upon which his reputation hangs, will be compared with the equally luscious top notes of other tenors who have sung "Celeste Aida" into the phono- graph before. him, .and who will sing it into a recording -horn years after he is dead.

The four jacks, which permit the op- erator to choose the stage he wants can be seen clearly in the accomp- anying schematic.
The features of the model VI can be summed up as having one dial tuning --one large dial for select- ing the desired station, the other large one to control sound volume. One small knob is for filament strength control and the other small knob is provided for fine tuning.
sages were received -from Poldhu up to a distance of 1,551 miles, 'S's' and other' test letters as far as 2,099 miles.
"The tape records of the signals are in my possession, and some of them are.. here exhibited to -night. The dis- tances at which they were received are all verified and countersigned by ?the Captain and chief officer of the ship, who were present during the tests.
"A result of some scientific interest, which I first noticed during the tests on the Steamship Philadelphia, was the very marked effect of sunlight ón the propa- gation of electric waves over great dis- tances.
"At the time. of these tests I was of the. opinion that this effect might have
.
been due to the loss of energy at the .transmitter. by daytime, 'caused by the diselectrification of. the highly charged transmitting elevated conductor operated by the influence 'of sunlight. I am now inclined to believe that the absorption of electric waves during daytime is due tó the ionization of the gaseous molecules of the air affecte-1 by ultra -violet. light, and as the ultra -violet 'rays which ema

only a comparatively short distance .us other directions, ±and 'that, with aerials of moderate ;height, -greater' efficiency in a given direction can be obtained than can be obtained 'all round by means of the ordinary 'aerials.
"When this type of aerial was adopted at Glace Bay, a considerable strengthen- ing of the received signals at Poldhu was noticed. It was, therefore, decided to adopt the directional aerial at all long- distance stations.
"A further improvement introduced at Clifden and Glace Bay consisted in the adoption of air condensers, composed of 'insulated metallic plates suspended iñ air ,at ordinary pressure: In this mari- ner it is 'possible to prevent the dissi- pation of energy due to losses caused by the dielectric of the condensers previous- ly employed, and a very appreciable economy in working, resulting from the absence of. breakages of the dielectric is effected, These air condensers, which have been in use since May of last year; have been' entirely satisfactory.

"The messages can now. be . transmit- .ed across the Atlantic by day as well is by night, but thereustill exist certain )eriods, fortunately of short duration, vhen transmission across the Atlantic is lifficult, and at times ineffective unless n .amount of energy greater than that ised ' during what I might call normal onditions is employed.
"Thus in the morning and evening, Men, due to the difference in longitude, aylight or darkness extends only part f the way across' the Atlantic, the re-, eived signals are weak and sometimes ease altogether_ "It , would almost appear as if illu-
linated space possessed for electric 'aves a 'different refractive index to ,.rk space, and that in consequence the ectric waves may be refracted and re- e.cted in passing from one medium to .e other.. It is, therefore, probable that ese difficulties would not .be experi- iced in telegraphing over equal dis- nces from north or south, .or vice :rsa, as in this case the passage from .yligbt to darkness would occur almost nultaneously in the whole of the me- al between the two points.

"Whatever may be the view as to its shortcomings and defects, there can be no doubt that wireless telegraphy across the Atlantic has come to stay, and will not only stay but continue to advance.
"Cable telegraphy across the Atlantic was subjected at the commencement to a series of discouraging failures' and dis- appointments, but whatever its difficul- ties I think I am not unjust in saying that it enjoyed one advantage over wire -

off the Record. The mechanical system of recording "cut" the records
with a style of sound that has a beauty of its own person-. ality. The picture and text below, which describe the mechanical system should be interesting to The Horn Speaker readers., who are not familiar with the old method of re- cording sound or refreshing to record enthusiasts, who are familiar with the method..
i OLD
How RECORDS ARE MADE FOR THE PUBLIC
Although the principle of the phonograph is now well known, the art of making records is deliberately shrouded in mystery. The particular composition of the wax -like "master" employed by a manufacturer is kept a profound secret. Few "outsiders" are permitted to see even the making of a record-certainly no one connected with a rival company. The proceeding is complex and calls for much skill, technical knowledge, and experience.
Imagine a great tenor, a popular operatic idol, about to immortalize his rendering of Verdi's "Celeste Aida." Before him is the mouth of a horn; behind him the orchestra. Even he does not see the actual recording equipment; for the small end of the horn .is located either behind a curtain or a partition. The musicians are poised between heaven and earth, for some of them sit on shelf -like benches, so that their heads are not far from the ceiling. So cramped are the quarters that often they assume positions at which a concert audience would gasp in amazement. For example, the trombonists sometimes turn their backs to the conductor; they follow him by keeping their eyes glued on mirrors by which his expressive beating of time is reflected: The loud instruments-the ponderous brasses-

are always placed in the rear so that their metallic blare may not drown out the finer tone of the strings, which are always to be found in front. The tenor soars up and down the scale directly into the yawning mouth of the horn. He gives his full- throated best; for he knows not only that his .rendition of "Celeste Aida" will be heard by thousands, perhaps by millions, but that the luscious top notes, upon which his reputation hangs, will be compared with the equally luscious top notes of other tenors who have sung "Celeste Aida" into the phono- graph before- him, and who will sing it into a recording -horn years after he is dead.

The four jacks, which permit the op- erator to choose the stage he wants can be seen clearly in the accomp- anying schematic.
The features of the model VI can be summed up as having one dial tuning --one large dial for select--. ing the desired station, the other large one to control sound volume. One small knob is for filament strength control and the other small knob is provided for fine tuning.
This is a fun set for collect - I
ors. It is easy to display in op- ^ erating condition almost anywhere an antenna is available. The bat-

" WiR. ., SS ODD ITL?.S"
"My assistants at Poldhu, in Cornwall, England, had received instructions to send on .and after December I1, during, certain hours every -day, a succession of .`S's' followed by a short message, the whole to be transmitted at a certain pre- arranged speed every ten minutes, alter- nating with five minutes' rest.
"On December 12 the signals trans- mitted from Cornwall were .clearly re- ceived at the prearranged times, in many cases a . succession of 'S's' being heard distinctly, although, probably in con- sequence . of the weakness of the sig- nals and the constant variations in the height of the receiving aerial, no actual message could be deciphered.
"The following day we were able to confirm the result. The signals were actually read by myself and by my as- sistant; Mr. G. S. Kemp.
"The result obtained, . although achieved with imperfect apparatus, was sufficient to convince me and my co- workers that by means of permanent stations-that is, stations not dependent on kites or balloons for. sustaining the elevated conductor-and by the employ- ment of more power in the transmitters
. it would be possible to send messages.. across the Atlantic Ocean with the same facility with which .they were being sent over much shorter distances.
"About two months later, in' Febru- ary, 1902, further tests were 'carried out between Poldhu 'and a receiving station on board the American liner Philadel- phia en route from Southampton' to New York. The sending apparatus at Poldhu was the same as that used for the New- foundland experiments. The receiving aerial on the ship was 'fixed to the main- mast, the top of which was 6o meters (197 feet) above sea level.
"As the elevated conductor was fixed and not floating about with a kite, as in the case of the Newfoundland experi- ments, good results were obtained on a syntonic receiver, and the signals were all recorded on tape by the ordinary Morse recorder.
"On the' Philadelphia readable mes- sages were received from Poldhu up to a distance of .1,551 miles, 'S's' and other 'test letters as far as 2,099 miles.
"The tape 'records of the signals are in my possession, and some of them are.. here exhibited to -night. The dis- tances at which they were received are all verified and countersigned by /the Captain and chief 'officer of . the ship, who were present during the tests.
"A result of some scientific interest, which I first noticed during the tests on the Steamship Philadelphia, was the very marked effect of 'sunlight an the propa- gation of electric waves over great dis- tances.
"At the time. of these tests I was of the. opinion that this effect might have been due to the loss of energy at the .transmitter. by daytime, 'caused by the diselectrification of. the highly charged transmitting elevated conductor operated by the influence of sunlight:. I am now 'inclined to believe that the absorption of electric waves during daytime is due tó the ionization of the gaseous molecules' of the air affect: -f by ultra -violet. light, and as the ultra -violet 'rays which emu -

nate from the sun are largely absorbed in the upper atmosphere of the earth, it is probable that the portion of the earth's atmosphere which is facing the sun will contain more ions or electrons than that portion which is in darkness, and therefore, as Prof. J. J. Thomson has shown, tnis illuminated and ionized 'air will absorb some of the energy of the electric waves.
"The . fact remains that clear sunlight and blue' skies, though transparent, to light, act as a kind of fog to powerful hertzian waves. Hence 'tee weather conditions prevailing in this country are usually suitable for long-distance wire- less telegraphy.
"The operation of the long-distance stations in England and America made it possible to transmit messages to ships, 'whatever their position, between Europe and North -America, and to the Cunard Company. belong the credit of having greatly encouraged the long-distance tests, a circumstance which enabled them to commence, in -June, 1904, the regular publication on their principal vessels of a daily newspaper, containing telegraphic messages of the latest news from Europe and America. .
"This daily newspaper has now been adopted by. nearly all . the large liners plying to New York and the Mediterra- nean, and it obviously owes its entire ex- istence to long-distance wireless teleg- raphy.
"In some of my earliest, experiments in -1896,1 used copper mirrors, by the aid of which it was possible to project a beam of. electric radiation in a certain direction, but I soon found that this methodwould only work over short dis- tances.
"About three years ago I again `took up the subject,' and was able to deter- miné than by means of horizontal aerials, disposed- in ..a particular manner, it was, possible to Confine the effects of electric waves mainly to certain directions as de- sired.. True,. the 'limitation of transmis- sion to one direction is not very sharply defined, but it is nevertheless very useful
"The practical result of this methoc has been so far that messages can b( Sent. over considerable distances in .th. desired directions, while they, travel ove only a comparatively short distanceTil other 'directions, 'and 'that, with aerial of moderate ,height, -greater- efficiency ii
á given direction can be obtained thai can be obtained 'all round by Means o the ordinary aerials.
"When this type of aerial was adopte' at Glace Bay, a considerable strengthen ing of the received signals at Poldhu wa noticed. It was, therefore, decided t adopt the directional aerial at all long distance stations.
"A further improvement introduced 1.
Clif den and Glace Bay consisted in th adoption of air condensers, composed c 'insulated metallic plates suspended 1
air,at ordinary pressure: In this mar ner. it is «possible to prevent the diss pation of energy due to losses caused b the dielectric of the condensers previous ly employed, and a very appreciab: economy in working, resulting from ti absence of. breakages of the dielectric, effected. These air condensers, whic have been in use since May of last yea have been, entirely satisfactory.

"After considerable time and expense the new station at Clifden was got ready for tests by the end of May, 19o7, and experiments were then *commenced with Glace Bay.
"The messages can now. be . transmit- ted across the Atlantic by day as well as by night, but thera,still exist certain periods, fortunately of short duration, when transmission across the Atlantic is difficult, . and at times ineffective unless an amount of energy greater than . that úsed during what I might Call normal conditions is employed.
"Thus in the morning and evening, when, due to the difference in longitude, daylight or darkness extends only part of the way across' the Atlantic, the re-, ceived signals' are weak and sometimes cease altogether.
"It would almost appear as if illu- minated space possessed for electric waves a ''different refractive index to dark space, and that in consequence the electric waves may be. refracted' and re- flected in passing from, one medium to the other. It is, therefore, probable that these difficulties would not be experi- enced in telegraphing over equal dis- tances from north or south, .or vice versa, as in this case the passage from .
daylight to darkness would occur almost simultaneously in the whole of the me- dium between the two points.
"In the same manner a storm area in the path of the signals 'often brings about a considerable weakening of the 'received waves, while if stormy conditions pre- vail all the way across the Atlantic no interference is noticeable. Electric wave shadows, like sound shadows, may be formed by the interference of reflected waves with the direct waves, whereby signals may be much less effective or im- perceptible in the area of such electric wave shadow. .
"In 'the same manner as there exist periods when signals across the Atlantic are unusually weak, there exist other conditions, especially at' night, which make -the signals abnormally strong. Thus on many occasions ships and sta- tions equipped with apparatus of a nor - 'ma] range of 200 miles have been able to communicate over distances of over z,ovu. This occurred recently, when a ship in the English Channel was able to correspond with another in the Medi- terranean. But the important factor about wireless telegraphy is that a ser- vice established for a certain distance shall be able to maintain reliable com- munication over that distance.
"The erection .of long-distance sta- tions for the purpose of telegraphing across the Atlantic met at the outset with the severe criticism of a certain important section of the English tech- nical press, which, although one ' would irnagine it existed for the purpose of en- couraging and promoting the progress of electrical science and industry, always seemed .more 'inclined to champion the particular interests of the 'cable com-
i panies. "Without wishing to enter into any
_ontroversy on this point, I venture to predict that' some of the statements pub- lished with reference to long-distance wireless telegraphy will make very amus- ing reading in a few years to come.
"Long-distance stations are now in course of erection in many parts ofthe world, the most powerful of all being that of the Italian Government at Col- tano, and I have not the slightest doubt that telegraphy through space will soon be in a position of affording communi- cation between distant countries at cheaper rates than can be obtained by any other means.
"As to .the practicability of wireless telegraphy working over long .distances such as that- separating' England from America, there is no longer need for any doubt. Although the stations have been worked for only a few hours daily, 119,- 945 words of press and commercial mes- sages had been transmitted across the ocean by this means up to the end of February last, since the service -was opened.
"The best judges of a service are those who have made use of it, and among newspapers the chief users have been the New York Times and the Lon- don Times, es, which have already publicly expressed their opinion of this new mttnod of communication.
"Whether the new telegraphy will or will not injure or displace the cables is

still a matter of conjecture, but in my opinion it rests a good deal on what the cables can do in the way of cheaper rates.
"Whatever may be the view as to its shortcomings and defects, there can be no doubt that wireless telegraphy across the Atlantic has come to stay, and will not only stay but continue to advance.
"Cable telegraphy across the Atlantic was subjected at the commencement to a series of discouraging failures' and dis- appointments, but whatever its difficul- ties I think I am not unjust in saying that it enjoyed one advantage over wire- less telegraphy, nangely, that it was free from the natural hostility' of vested in- terests representing over sixty millions sterling, now invested in cables, which rightly or wrongly consider long-distance telegraphy as menacing their interests.
"In seven years the useful range, of wireless has increased from 206 to 2,500 miles. In view of that fact, he will be a bold prophet who will venture to.affiirm what may not be done in seven years more.
"Among many people there seems 'to be a rooted conviction that Wireless telegraphy is not suitable for the hand- ling of code or cipher messages. What- ever gave rise to this idea I do not know, but I wish to emphasize that it is purely fictitious. Code messages can be sent just as well by wireless as' by ordinary methods of telegraphy.
"I do not wish to claim that wireless telegraphy is infallible, and although er- rors do sometimes, occur it is absolutely certain that, having regard to the Lon- don and Montreal service, most of the mistakes can be traced to the land line telegraph transmission between London and Clifden, and between Glace Bay and Montreal. .
"I find, however, that probably the greatest ignorance -prevails in regard to what is termed 'tapping,' or intercepting, wireless messages. No telegraph system is secret. The contents of every tele- gram are known to every operator who handles it.
"Nevertheless, there are penalties at- tached to the tapping of a telegraph wire, and it ought to be as well known that; since the passing of the Wireless Telegraphy act in England, there are penalties involved if any u ireless sta-' tions are erected or worked without the consent of the Postmaster -General.
"In conclusion I may say that I am very confident that it is only a question of time, and not a very long time, before wireless telegraphy over great. distances; possibly round the world, will become an .indispensable aid' to ;com- merce and civilization."

The electrolytic cup is taken from the battery with the carbon left in. Then the carbon is cut off within 1/8 -inch of the top of the cup and a /-inch hole bored in. This is to contain the sul- phuric acid. One inch of Wollaston wire is then soldered into the screw. This can be bought at some mineral or elec- trical store. A 3 -point switch is con- nected on the base so that you can use any detector you like.

In the same yew,r Victor sold phonographs from X10.00 to :./250.00.
The Victor V with an exalted horn was constructed of quartered
oak and cost U60.00. The Victor I is a favorite on which to
play old disc records and savor the original recording style of
Farrar's old records.
