INTRODUCTION

SCOPE OF THIS MANUALThis manual is intended for use by experienced techni-

cians familiar with similar types of commercial grade commu-nications equipment. It contains all required service informa-tion for the equipment and is current as of this publicationdate. Changes which may occur after publication are coveredby either Service Bulletins or Manual Revisions, which areissued as required.

ORDERING REPLACEMENT PARTSWhen ordering replacement parts or equipment informa-

tion, the full part identification number should be included.This applies to all parts : components, kits, and chassis. If thepart number is not known, include the chassis or kit numberof which it is a part and a sufficient description of the requiredcomponent for proper identification.

PERSONNEL SAFETYThe following precautions are recommended for person-

nel safety :• DO NOT transmit if someone is within two feet (0.6

meter) of the antenna.• DO NOT transmit until all RF connectors are secure and

any open connectors are properly terminated.• SHUT OFF this equipment when near electrical blasting

caps or while in an explosive atmosphere.• All equipment should be properly grounded before power-

up for safe operation.• This equipment should be serviced by only qualified tech-

nicians.

PRE-INSTALLATION CONSIDERATIONS

1. UNPACKINGUnpack the radio from its shipping container and check for

accessory items. If any item is missing, please contactKENWOOD immediately.

2. LICENSING REQUIREMENTSFederal regulations require a station license for each radio

installation (mobile or base) be obtained by the equipmentowner. The licensee is responsible for ensuring transmitterpower, frequency, and deviation are within the limits permit-ted by the station license.

Transmitter adjustments may be performed only by a li-censed technician holding an FCC first, second or generalclass commercial radiotelephone operator’s license. There isno license required to install or operate the radio.

3. PRE-INSTALLATION CHECKOUT

3-1. IntroductionEach radio is adjusted and tested before shipment. How-

ever, it is recommended that receiver and transmitter opera-tion be checked for proper operation before installation.

3-2. TestingThe radio should be tested complete with all cabling and

accessories as they will be connected in the final installation.Transmitter frequency, deviation, and power output shouldbe checked, as should receiver sensitivity, squelch operation,and audio output. Signalling equipment operation should beverified.

4. PLANNING THE INSTALLATION

4-1. GeneralInspect the vehicle and determine how and where the ra-

dio antenna and accessories will be mounted.Plan cable runs for protection against pinching or crushing

wiring, and radio installation to prevent overheating.

4-2. AntennaThe favored location for an antenna is in the center of a

large, flat conductive area, usually at the roof center. Thetrunk lid is preferred, bond the trunk lid and vehicle chassisusing ground straps to ensure the lid is at chassis ground.

4-3. RadioThe universal mount bracket allows the radio to be

mounted in a variety of ways. Be sure the mounting surfaceis adequate to support the radio’s weight. Allow sufficientspace around the radio for air cooling. Position the radio closeenough to the vehicle operator to permit easy access to thecontrols when driving.

4-4. DC Power and wiring1. This radio may be installed in negative ground electrical

systems only. Reverse polarity will cause the cable fuse toblow. Check the vehicle ground polarity before installationto prevent wasted time and effort.

2. Connect the positive power lead directly to the vehiclebattery positive terminal. Connecting the Positive lead toany other positive voltage source in the vehicle is not rec-ommended.

3. Connect the ground lead directly to the battery negativeterminal.

4. The cable provided with the radio is sufficient to handlethe maximum radio current demand. If the cable must beextended, be sure the additional wire is sufficient for thecurrent to be carried and length of the added lead.

• VOLUME UP/DOWN keyWhen the key is pressed, the volume level is increased/

decreased and repeats if held for 200ms or longer.

• BUSY/TX LEDThe BUSY indicator (Green LED) shows that the channel is

in use. The TX indicator (Red LED) shows that you are trans-mitting.

3-2. Programmable KeysThe FPU (KPG-70D) enables programmable keys to select

the following functions.• Emergency• Key Lock• Monitor• Scan ON/OFF• Talk Around• Temporary Delete• None• AUX• Horn Alert• Scan + Temporary Delete

• EmergencyPressing this key for longer than 1 second causes the

transceiver to enter the emergency mode. The transceiverjumps to the programmed “Emergency channel” and trans-mits for 25* seconds.

The transceiver disables mic mute while transmitting. Af-ter finishing transmission, the transceiver receivers for 5*seconds. The transceiver Mute* the speaker while receiving.Following the above sequence, the transceiver continues totransmit and receive.* Default value.

• Key lockPressing this key causes the transceiver to accept entry of

only the [Vol Up/Down]*, [Key lock], Microphone [PTT],[Monitor], [Emergency], and [Power] keys.* Programmable

4. Scan Operating

SCAN start conditionTwo or more channels must be added to all channels that

can be scanned. The transceiver must be in normal receivemode (PTT off).

When you activate the key programmed to the scan ON/OFF function, the scan starts. The indicator next to the pro-grammed key LED blinks.

Scan stop conditionThe scan stops temporarily if the following conditions are

satisfied.1) A carrier is detected, then QT/DQT matches on channels

for which receive the QT/DQT is set by the programmingsoftware.

2) A carrier is detected on the channels for which receivingQT/DQT is not set by the programming software or whenthe monitor (signalling cancel) function is activated.

Revert channelThe revert channel is used to transmit during scanning and

set by the programming software (KPG-70D).1) Selected channel

The transceiver reverts to the channel before scanning orthe channel that you changed during scan.

2) Selected with talkbackThe transceiver reverts to the selected channel prior toscan initiation.However, if a call is received on a channel other then theselected channel and PTT is pressed before scanning re-sume, the transceiver “talks back” on the current receivechannel.

Scan endWhen you press the key programmed to the scan function

during scan mode, the scan ends.The indicator next to the programmed key LED turns off.

Temporary deleteIt is possible to delete channel temporary during scan.

When scan stops on unnecessary channel for example by in-terference of the other party, activate the delete function (forexample press and hold the key for approximately one sec-ond), then that channel is deleted temporarily and scan re-start immediately.

The temporary deleted channels return to pre-set delete/add channels, when the transceiver is turned off or the scanfunction is switched off.

5. Details of Features

Time-out timerThe time-out timer can be programmed in 30 seconds in-

crements from 30 seconds to five minutes and off. If thetransmitter is transmitted continuously for longer than theprogrammed time, the transmitter is disabled and a warningtone sounds while the PTT button is held down. The warningtone stops when the PTT button is released.

PTT IDPTT ID provides a DTMF ANI or MSK ID to be sent with

every time PTT (connect ID at beginning of transmission, dis-connect ID at end of transmission, or both).

You can program PTT ID “on” or “off” for each groupchannel (DTMF). The contents of ID are programmed foreach transceiver.

The transceiver is capable to have ID. The format isDTMF. The timing that the transceiver sends ID is program-mable.

BOT : Connect ID is sent on beginning of transmission.EOT : Disconnect ID is sent on end of transmission.Both : Connect ID is sent on beginning of transmissionand disconnect ID is sent on end of transmission.There is also “PTT ID” setting for each channel.

Off hook decodeIf the Off hook decode function has been enabled, remov-

ing and replacing the microphone on the hook has no effectfor decoding QT/DQT and option signalling.

“TOT” pre-alertThe transceiver has “TOT” pre-alert timer. This param-

eter selects the time at which the transceiver generates“TOT” pre-alert tone before “TOT” is expired.

“TOT” will be expired when the selected time passesfrom a TOT pre-alert tone.

“TOT” re-key timeThe transceiver has “TOT” re-key timer. This timer is the

time you can not transmit after “TOT” exceeded. After“TOT” re-key time expired you can transmit again.

“TOT” reset timeThe transceiver has “TOT” reset timer. This timer is the

minimum wait time allowed during a transmission that willreset the “TOT” count.

“TOT” reset time causes the “TOT” to continue even af-ter PTT is released unless the “TOT” reset timer has expired.

Clear to transpondThe transceiver waits the transpond of DTMF if channel is

busy until channel open. This feature prevents the interfer-ence to other party.

6. Option Signalling (DTMF)Built-in DTMF decoder is available for option signalling.It is possible to use individual call, group call, Stun.If the option signalling matches, a predetermined action

will occur.If option signalling matches on a channel is set up with

option signalling, the channel LED will flash and option signal-ling will be released. The transpond or alert tone will sound.

While option signalling matches (or if option signalling isdeactivated when you are transmitting), you can mute orunmute QT/DQT/Carrier.

DQT+DTMF can not be selected.

Auto ResetIf option signalling matches a group set up with option sig-

nalling, option signalling is released. After matching optionsignalling, option signalling will temporarily reset automati-cally.

StunIf the stun code matches, a predetermined action will oc-

cur. Whether option signalling is activated or not, when stunmatches on any channel, the transceiver will become TX in-hibited or TX/RX inhibited. While stun is active, if the stuncode + “#” code is received, stun will deactivate.

When stun matches, transpond will function. Alert willnot be output.

7. Audible User Feedback TonesThe transceiver outputs various combinations of tones to

notify the user of the transceiver operating state.Refer to the help file on the KPG-70D, regarding the func-

tions that are not listed below.

Stun on toneWhen a stun code is received, transpond tone sounds.

Stun off toneWhen a stun release code is received, transpond tone

sounds.

Group call toneSounds when a group call with the correct DTMF option

signalling is received, repeats 7 times. You can select yes orno in the Alert tone level setting.

Individual call toneSounds when an individual call with the correct DTMF op-

tion signalling is received. You can select yes or no in theAlert tone level setting.

Key input error toneSounds when a key is pressed but that key cannot be

used. You can select yes or no for the optional feature'swarning tone.

Transpond toneSounds when an individual call with the correct DTMF op-

tion signalling is received. For group calls, only the grouptone will sound, not the transpond tone.

Pre alert toneSounds prior to the TOT TX inhibit activation. If TOT pre

alert is set, the tone sounds at the amount of time pro-grammed, before the TOT expires (TOT time – TOT pre alerttime = Pre alert tone sounding time). You can select yes orno for the optional feature’s warning tone.

Transmit protectionThe final FET is protected against heat while transmitting

by making the radio cuts down TX power when the tempera-ture of the final FET becomes higher than reference. Afterthat, if the temperature continue to rise, transmission isstopped. The final FET is also protected against over voltageby having the radio to check that the voltage of power supplyconnected to the radio is not higher than about 17V when theradio is turned on, otherwise it can not transmit. In bothcases when transmission is stopped, a beep will continue tosound until the PTT key is released.

Frequency ConfigurationThe receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscil-lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the necessaryfrequencies. Figure 1 shows the frequencies.

CIRCUIT DESCRIPTION

Receiver SystemThe receiver is double conversion superheterodyne. The

frequency configuration is shown in Figure 1.

Front-end RF AmplifierAn incoming signal from the antenna is applied to an RF

amplifier (Q353) after passing through a transmit/receiveswitch circuit (D603, D604, D605 are off) and a band passfilter (L357, L356 and varactor diodes : D353, D354). Afterthe signal is amplified (Q353), the signal is filtered through aband pass filter (L354, L355 and varactor diodes: D351,D352) to eliminate unwanted signals before it is passed tothe first mixer.

The voltage of these diodes are controlled by tracking theCPU (IC101) center frequency of the band pass filter. (SeeFig. 2)

First MixerThe signal from the RF amplifier is heterodyned with the

first local oscillator signal from the PLL frequency synthesizercircuit at the first mixer (Q352) to create a 49.95MHz firstintermediate frequency (1st IF) signal. The first IF signal isthen fed through one pair of monolithic crystal filter (MCF :XF351) to further remove spurious signals.

Wide/Narrow Changeover CircuitThe Wide port (pin 65) and Narrow port (pin 64) of the CPU

is used to switch between ceramic filters. When the Wideport is high, the ceramic filter SW diodes (D303, D302) causeCF301 to turn on to receive a Wide signal.

When the Narrow port is high, the ceramic filter SW di-odes (D303, D302) cause CF302 to turn on to receive a Nar-row signal.

AF Signal SystemThe detection signal from IF IC (IC301) goes to D/A con-

verter (IC161) to adjust the gain and is output to AF filter(IC251) for characterizing the signal. The AF signal outputfrom IC251 and the DTMF signal, BEEP signal are summedand the resulting signal goes to the D/A converter (IC161).The AFO output level is adjusted by the D/A converter. Thesignal output from the D/A converter is input to the audiopower amplifier (IC252). The AF signal from IC252 switchesbetween the internal speaker and speaker jack (J1) output.

Squelch CircuitThe detection output from the FM IF IC (IC301) passes

through a noise amplifier (Q301) to detect noise. A voltage isapplied to the CPU (IC101). The CPU controls squelch ac-cording to the voltage (SQIN) level. The signal from the RSSIpin of IC301 is monitored. The electric field strength of thereceive signal can be known before the SQIN voltage is inputto the CPU, and the scan stop speed is improved.

PLL Frequency SynthesizerThe PLL circuit generates the first local oscillator signal for

reception and the RF signal for transmission.

PLLThe frequency step of the PLL circuit is 5 or 6.25kHz. A

16.8MHz reference oscillator signal is divided at IC401 by afixed counter to produce the 5 or 6.25kHz reference fre-quency. The voltage controlled oscillator (VCO) output signalis buffer amplified by Q410, then divided in IC401 by a dual-module programmable counter. The divided signal is com-pared in phase with the 5 or 6.25kHz reference signal in thephase comparator in IC401. The output signal from thephase comparator is filtered through a low-pass filter andpassed to the VCO to control the oscillator frequency. (SeeFig. 6)

VCOThe operating frequency is generated by Q406 in transmit

mode and Q405 in receive mode. The oscillator frequency iscontrolled by applying the VCO control voltage, obtainedfrom the phase comparator, to the varactor diodes (D405 andD406 in transmit mode and D403 and D404 in receive mode).The TX/RX pin is set low in receive mode causing Q408 andQ407 to turn Q406 off, and turn Q405 on. The TX/RX pin isset high in transmit mode. The outputs from Q405 and Q406are amplified by Q410 and sent to the RF amplifiers.

Unlock CircuitDuring reception, the 8RC signal goes high, the 8TC signal

goes low, and Q34 turns on. Q33 turns on and a voltage isapplied to the collector (8R). During transmission, the 8RCsignal goes low, the 8TC signal goes high and Q36 turns on.Q35 turns on and a voltage is applied to 8T.

The CPU in the control unit monitors the PLL (IC401) LDsignal directly. When the PLL is unlocked during transmis-sion, the PLL LD signal goes low. The CPU detects this sig-nal and makes the 8TC signal low. When the 8TC signal goeslow, no voltage is applied to 8T, and no signal is transmitted.

Transmitter System

OutlineThe transmitter circuit produces and amplifies the desired

frequency directly. It FM-modulates the carrier signal bymeans of a varicap diode.

Power Amplifier CircuitThe transmit output signal from the VCO passes through

the transmission/reception selection diode (D409) and ampli-fied by Q501, Q502 and Q503. The amplified signal goes tothe final amplifier (Q504) through a low-pass filter. The low-pass filter removes unwanted high-frequency harmonic com-ponents, and the resulting signal is goes the antenna termi-nal.

APC CircuitThe automatic transmission power control (APC) circuit

detects part of a final amplifier output with a diode (D606,D607) and applies a voltage to IC501. IC501 compares theAPC control voltage (PC) generated by the D/A converter(IC161) and DC amplifier (IC203) with the detection outputvoltage. IC501 generates the voltage to control Q503 andQ504 and stabilizes transmission output.

The APC circuit is configured to protect over current ofQ503 and Q504 due to fluctuations of the load at the antennaend and to stabilize transmission output at voltage and tem-perature variations.

Control CircuitThe CPU carries out the following tasks:

1) Controls the WIDE, NARROW, TX/RX outputs.2) Adjusts the AF signal level of the AF filter (IC251) and

turns the filter select compounder on or off.3) Controls the display unit.4) Controls the PLL (IC401).5) Controls the D/A converter (IC161) and adjusts the vol-

ume, modulation and transmission power.

Memory CircuitThe transceiver has an 64k-bit EEPROM (IC66). The

EEPROM contains adjustment data. The CPU (IC101) con-trols the EEPROM through three serial data lines.

Display CircuitThe shift register controls the display LEDs through the CL

and DI lines from the CPU (IC101).When the transceiver is busy, LED G line becomes high

impedance, turning on Q4 and the green LED (D11) lights, intransmit mode, the LED R line becomes low impedance, andthe red LED (D12) lights.

Backlit LEDs (D1~D4) are provided and will only goes offwhen MBL line becomes low impedance.

When a function key (MON, PF, C1, C2, C3 or C4) is se-lected, its respective line becomes low impedance (LEDMON, LED PF, LED C1, LED C2, LED C3 or LED C4), theamber LED lights.

Key Matrix CircuitThe TK-7102H front panel has function keys. Each of

them is connected to a cross point of a matrix of the KMI1 toKMO2 ports of the microprocessor. The KMO1 to KMO2ports are always high, while the KMI1 to KMI4 ports are al-ways low.

The microprocessor monitors the status of the KMI1 toKMO2 ports. If the state of one of the ports changes, themicroprocessor assumes that the key at the matrix point cor-responding to that port has been pressed.

CIRCUIT DESCRIPTION

EncodeThe QT and DQT signals are output from QT/DQT of the

CPU (IC101) and summed with the external pin DI line by thesumming amplifier (IC203) and the resulting signal goes tothe D/A converter (IC161). The DTMF signal is output fromDTMF of the CPU and goes to the D/A converter (IC161). Thesignal is summed with a MIC signal by the summing amplifier(IC203), and the resulting signal goes to the D/A converter(IC161).

The D/A converter (IC161) adjusts the MO level and thebalance between the MO and QT/DQT levels. Part of a QT/DQT signal is summed with MO and the resulting signal goesto the VCOMOD pin of the VCO. This signal is applied to avaricap diode in the VCO for direct FM modulation.

• QT/DQT/DTMFThe signal (W/NO (EVOL2)) goes to SIGNAL (pin 88) of

CPU (IC101). The QT/DQT signal will pass through the low-pass filters in the CPU (IC101) and be decoded within theCPU (IC101). The DTMF signal will be decoded within theCPU (IC101).

D/A ConverterThe D/A converter (IC161) is used to adjust MO modula-

tion, AF volume, TV voltage, FC reference voltage, and PCPOWER CONTROL voltage level.

Adjustment values are sent from the CPU as serial data.The D/A converter has a resolution of 256 and the followingrelationship is valid:

D/A output = (Vin – VDAref) / 256 x n + VDArefVin: Analog inputVDAref: D/A reference voltagen: Serial data value from the microprocessor (CPU)

Power Supply CircuitWhen the power switch on the display unit is pressed, the

power port on the display unit which is connected port 17(POWER), goes low, then port 82 (SBC) goes high, Q32 turnson, SB SW (Q31) turns on and power (SB) is supplied to theradio.

When the DC power supplied to the radio, the voltageregulator IC (IC33) supply into the CPU VDD and reset voltagedetect IC (IC34). IC34 will generate signal (RESET) in to thereset terminal on the CPU (IC101) to carry out a power ONreset. Also, CPU (IC101) is checking on port 91 (Battery Volt-age). If DC power is less than about 9.5V, the radio is unableto power on.

When the DC power voltage deceases from normal volt-age, the INT voltage detector IC (IC35) will set to high on CPUport 18 (INT) if B line will became less than about 9.5V. ThenCPU send to EEPROM (IC66) the backup data and go intoSTOP mode.

This circuit has an overvoltage protection circuit. If a DCvoltage of 18V or higher is applied to the base of Q61, thisvoltage turns Q61 on and turns Q32 and SB off.

If normal power is not obtained, please follow the

step belowOpen the shielding cover (upper), and screw 3 locationsaround ANT pin.1. Switch off the transceiver.

Impedance of Final FET (Q504) and Drive FET (Q503) canbe measured easily using DVM Ω mode.Normal condition – Gate : 20kΩ~50kΩ, Drain : 1MΩ~2MΩThe above impedance values are rough estimations.

2. Switch on the transceiver. Check the voltage at F501 out-put point.The voltage is around 13.6V in receiving condition. Thevoltage will be 12.6V~ in transmitting condition. If found0V at this point then F501 is broken.

3. Remove R516.

4. Connect 50Ω load at the ANT location.Transmit and check current drain at High power mode.If the current drain is less than 1A, then Final FET is bro-ken.If the current drain is less than 5.0A, short the Drive FETgate to ground, and check the current drain.If the current drain is not 0.1A less than the original value,then the Drive FET is broken.

5. Check input power level at Drive FET gate location.Connect the wire to [RF] location.Transmit and check for power to be within the range of0.3W~0.6W.If power found is less than 0.3W, check the circuit beforethe Drive FET.
