PRE-INSTALLATION CONSIDERNATIONS

1. UNPACKING

Unpack the radio from its shipping container and check

for accessory items. If any item is missing, please contact

KENWOOD immediately.

2. LICENSING REQUIREMENTS

Federal regulations require a station license for each ra-

dio installation (mobile or base) be obtained by the equip-

ment owner. The licensee is responsible for ensuring trans-

mitter power, frequency, and deviation are within the limits

permitted by the station license.

Transmitter adjustments may be performed only by a li-

censed technician holding an FCC first, second or general

class commercial radiotelephone operator’s license. There

is no license required to install or operate the radio.

GENERAL

3. PRE-INSTALLATION CHECKOUT

3-1. Introduction

5. INSTALLATION PLANNING – CONTROL STATIONS

5-1. Antenna system

Each 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.

Control station. The antenna system selection depends

on many factors and is beyond the scope of this manual.

Your KENWOOD dealer can help you select an antenna sys-

tem that will best serve your particular needs.

3-2. Testing

5-2. Radio location

The radio should be tested complete with all cabling and

accessories as they will be connected in the final installa-

tion. Transmitter frequency, deviation, and power output

should be checked, as should receiver sensitivity, squelch

operation, and audio output. Signalling equipment operation

should be verified.

Select a convenient location for your control station radio

which is as close as practical to the antenna cable entry

point. Secondly, use your system’s power supply (which

supplies the voltage and current required for your system).

Make sure sufficient air can flow around the radio and power

supply to allow adequate cooling.

4. PLANNING THE INSTALLATION

4-1. General

SERVICE

Inspect the vehicle and determine how and where the

radio antenna and accessories will be mounted.

Plan cable runs for protection against pinching or crush-

ing wiring, and radio installation to prevent overheating.

This radio is designed for easy servicing. Refer to the

schematic diagrams, printed circuit board views, and align-

ment procedures contained in this manual.

Note

4-2. Antenna

The favored location for an antenna is in the center of a

large, flat conductive area, usually at the roof center. The

trunk lid is preferred, bond the trunk lid and vehicle chassis

using ground straps to ensure the lid is at chassis ground.

When you modify your radio as described in system set-

up, take the following precaution.

The rating of pin 7 (SB) of the accessory connector cable

(KCT-19) on the rear of the radio is 13.6V (1A). Insert a 1A

fuse if you use the SB pin for external equipment.

4-3. Radio

Accessory connector

cable (KCT-19)

The universal mount bracket allows the radio to be

mounted in a variety of ways. Be sure the mounting surface

is adequate to support the radio’s weight. Allow sufficient

space around the radio for air cooling. Position the radio

close enough to the vehicle operator to permit easy access

to the controls when driving.

–

4-4. DC Power and wiring

1. This radio may be installed in negative ground electrical

systems only. Reverse polarity will cause the cable fuse

to blow. Check the vehicle ground polarity before installa-

tion to prevent wasted time and effort.

2. Connect the positive power lead directly to the vehicle

battery positive terminal. Connecting the Positive lead to

any other positive voltage source in the vehicle is not rec-

ommended.

If you do not intend to use the 3.5-mm jack for the exter-

nal speaker, fit the supplied speaker-jack cap (B09-0235-05)

to stop dust and sand getting in.

3. Connect the ground lead directly to the battery negative

terminal.

4. The cable provided with the radio is sufficient to handle

the maximum radio current demand. If the cable must be

extended, be sure the additional wire is sufficient for the

current to be carried and length of the added lead.

TK-760G/762G

OPERATING FEATURES

3) Selected channel

■ SCAN start condition

The transceiver reverts to the channel before scanning or

the channel that you changed during scan.

4) Last called channel

One or more non-priority channels must be added to all

channels that can be scanned. The transceiver must be in

normal receive mode (PTT off).

The transceiver reverts to the last called channel during

the scan.

5) Last used channel

When you activate the key programmed to the scan func-

tion, the scan starts. The scan icon "SCN" lights and "SCAN"

is indicated on alphanumeric display.

The transceiver reverts to the last used (transmitted)

channel during scan. "Last used" revert channel includes

talkback function.

■ Scan stop condition

The scan stops temporarily if the following conditions are

satisfied.

1) A carrier is detected, then signalling matches on chan-

nels for which receive the signalling is set by the pro-

gramming software.

2) A carrier is detected on the channels for which receiving

signalling is not set by the programming software or

when the monitor (signalling cancel) function is activated.

6) Selected with talkback

The transceiver reverts to the channel before scanning or

the channel that you changed during scan.

■ Scan end

When you reactivate the key programmed to the scan

function during scan mode, the scan ends.

The scan icon "SCN" and "SCAN" display goes off.

■ Scan channel types

■ Temporarily delete/add

1) Priority channel is the most important channel for the

scan, and always detects a signal during scan and when

the scan stops temporarily.

2) Non-priority channels detects a signal during scan. For

the channels that can be selected with the group or chan-

nel up/down key when the scan does not occur, adds an

indicator "A" lights.

It is possible to delete or add channel temporarily during

scan. When scan stops on unnecessary channel for ex-

ample by interference of the other party, activate the delete/

add function (for example press the key), then that channel

is deleted temporarily and scan re-start immediately.

When you would like to add the deleted channel tempo-

rarily to scan sequence, select the desired (deleted) channel

during scan, activate the delete/add function (for example

press the key) before scan re-start.

■ Priority channel setting

A priority channel can be set as follows with the program-

ming software (KPG-56D).

1) Specify a priority channel as a fixed priority channel.

2) Make a selected channel, a priority channel.

That channel is added temporarily to scan sequence. The

temporary deleted or added channels are returns to pre-set

delete/add, when the transceiver exits from scan mode.

■ Scan type according to the priority channel

1) When no priority channel is set : Only the non-priority

channels are scanned.

If a non-priority channel stops temporarily, it stops until

there is no signal on the channel.

5. Details of Features

■ Time-out timer

The time-out timer can be programmed in 15 seconds

increments from 15 seconds to ten minutes. If the transmit-

ter is keyed continuously for longer than the programmed

time, the transmitter is disabled and a warning tone sounds

while the PTT button is held down. The alert tone stops

when the PTT button is released.

2) When priority channel is set : Either priority channel is

scanned.

If a non-priority channel stops temporarily, a priority chan-

nel signal is detected at certain intervals.

If a priority channel stops temporarily, it stops until there

is no signal on the priority channel.

■ PTT ID

PTT ID provides a DTMF ANI to be sent with every time

PTT (beginning of transmission, end of transmission, or

both).

You can program PTT ID "on" or "off" for each group. The

contents of ID are programmed for each channel.

The timing that the transceiver sends ID is program-

mable.

■ Revert channel

The revert channel is used to transmit during scanning

and set by the programming software (KPG-56D).

1) Priority

The transceiver reverts to the priority channel.

2) Priority with talkback

BOT : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission.

EOT : DTMF ID (EOT)/MSK ID is sent on end of transmis-

sion.

Both : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission and DTMF ID (EOT)/MSK ID is sent on end

of transmission.

The transceiver reverts to the priority channel.

If you press PTT during a resume timer (dropout delay

time, TX dwell time) or calling, you can transmit on cur-

rent channel to answer to the call however revert channel

is set to priority channel.

After resume time, scan re-starts and transmission chan-

nel is return to priority channel.

TK-760G/762G

OPERATING FEATURES

■ Off hook decode

■ AND/OR

If the Off hook decode function has been enabled, re-

moving and replacing the microphone on the hook has no

effect for decoding QT/DQT and option signalling.

You can select AND or OR for option signalling match

conditions.

Alert/Transpond

AND QT/DQT+DTMF (2-tone); Option matches = Action

■ "TOT" pre-alert

QT/DQT+DTMF (2-tone); Option matches = Action

AF mute open

The transceiver has "TOT pre-alert timer. This parameter

selects the time at which the transceiver generates "TOT"

pre-alert tone before "TOT" is expired.

"TOT" will be expired when the selected time passes

from a TOT pre-alert tone.

AND QT/DQT+DTMF (2-tone); Option matches = Action

OR QT/DQT/ID; Signalling only matches = Action

With OR set up, alert/transpond will not function with

only DTMF.

■ "TOT" re-key time

The 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.

With OR set up, AF mute will not release when only

DTMF matches.

With a conventional channel not set up with QT or DQT,

only the carrier is considered when signalling matches.

■ "TOT" reset time

■ Auto Reset

The transceiver has "TOT" reset timer. This timer is the

minimum wait time allowed during a transmission that will

reset the "TOT" count.

"TOT" reset time causes the "TOT" to continue even after

PTT is released unless the "TOT" reset timer has expired.

If option signalling matches a group set up with option

signalling, option signalling is released. After matching op-

tion signalling, option signalling will temporarily reset auto-

matically.

■ OST (Operator Selectable Tone)

(TK-760G K market models only)

The transceiver is capable to have "OST" function and 16

tone pair (QT/DQT).

■ Dead Beat Disable

If the D.B.D. code matches, a predetermined action will

occur. Whether option signalling is activated or not, when

D.B.D. matches on any channel, the transceiver will become

TX inhibited or TX/RX inhibited. While D.B.D. is active, if the

D.B.D. code + "#" code is received, D.B.D. will disactivate.

When D.B.D. matches, transpond will function. Alert will

not be output, and option signalling match icon will not ap-

pear.

■ Clear to transpond

The transceiver waits the transpond of 2-tone /DTMF if

channel is busy until channel open. This feature prevents

the interference to other party.

6. Option Signalling (DTMF/2-Tone)

7. Audible User Feedback Tones

The transceiver outputs various combinations of tones to

notify the user of the transceiver operating state. The main

tones are listed below.

The high tone is 1477Hz, the mid tone is 941Hz, and the

low tone is 770Hz.

Built-in DTMF decoder is available for option signalling.

Built-in 2-tone decoder is available for option signalling.

It is possible to use individual call, group call, D.B.D.

(Dead Beat Disable). D.B.D. is used with DTMF only.

If the option signalling matches, a predetermined action

will occur.

If option signalling matches on a group/channel which is

set up with option signalling, the option signalling indicator

(CALL) will flash and option signalling will be released. The

transpond or alert tone will sound.

■ Power on tone

This tone is output when the transceiver is turned on.

(The high tone is output for 500ms.)

The orange LED will flash.

■ Alert tone

While option signalling matches (or if option signalling is

deactivated when you are transmitting), you can mute or

unmute QT/DQT/Carrier.

This tone is output when the transceiver is TX inhibition

for TOT, and PLL unlocked. It is output until the PTT button

is released.

■ DBD on tone

When a D.B.D. code is received, transpond tone sounds.

■ DBD off tone

When a D.B.D. release code is received, transpond tone

sounds.

REALIGNMENT

5-4. Programming Software Description

4. Check Sum

Executing this function, "TUNING" apears on the display

of the TK-760G while calculation the check sum.

When the calculation is completed, the display returns to

normal and PC displays the check sum of the radio.

The KPG-56D programming disk is supplied in 3-1/2" disk

format. The software on this disk allows a user to program

TK-760G/762G radio via a programming interface cable

(KPG-46).

5-5. Programming With IBM PC

5. PC Mode

5-1. Preface

If data is transferred to the transceiver from an IBM PC

with the KPG-56D, the destination data (basic radio informa-

tion) for each set can be modified. Normally, it is not neces-

sary to modify the destination data because their values are

determined automatically when the frequency range (fre-

quency type) is set.

The values should be modified only if necessary. Data

can be programmed into the flash memory in RS-232C for-

mat via the modular microphone jack.

The TK-760G/762G transceiver is programmed using a

personal computer, a programming interface (KPG-46) and

programming software (KPG-56D).

The programming software can be used with an IBM PC

or compatible. Figure 1 shows the setup of an IBM PC for

programming.

5-2. Connection Procedure

1. Connect the TK-760G/762G to the personal computer

with the interface cable.

2. When the Power is switched on, user mode can be en-

tered immediately. When the PC sends a command, the

radio enters PC mode.

6. Firmware Programming Mode

6-1. Preface

Flash memory is mounted on the TK-760G/762G. This

allows the TK-760G/762G to be upgraded when new fea-

tures are released in the future. (For details on how to ob-

tain the firmware, contact Customer Service.)

When data is transmitted from transceiver, the red LED

blink.

When data is received by the transceiver, the green LED

blink.

6-2. Connection Procedure

Connect the TK-760G/762G to the personal computer

(IBM PC or compatible) with the interface cable (KPG-46).

(Connection is the same as in the PC Mode.)

Notes :

• The data stored in the personal computer must match

model type when it is written into the flash memory.

• Change the TK-760G/762G to PC mode, then attach the

interface cable.

6-3. Programming

1. Start up the programming software (KPG-56D), select

"firmware program" in the "Program" item, and press the

Return key on your personal computer. This starts up the

firmware programmer.

2. The top screen is displayed. Press any key to advance to

the next screen.

3. Set the communications speed (normally, 57600 bps)

and communications port in the Setup item.

4. Set the firmware to be updated by File select (=F1).

5-3. KPG-46 Description

(PC programming interface cable : Option)

The KPG-46 is required to interface the TK-760G/762G to

the computer. It has a circuit in its D-subconnector (25-pin)

case that converts the RS-232C logic level to the TTL level.

The KPG-46 connects the modular microphone jack of

the TK-760G/762G to the computers RS-232C serial port.

5. Turn the TK-760G/762G Power ON with the [CH

]

switch held down. Hold the switch down for two sec-

onds until the display changes to "PROG 576", the BUSY/

TX LED lights orange. When "PROG 576" appears, re-

lease your finger from the switch.

KPG-46

6. Check the connection between the TK-760G/762G and

the personal computer, and make sure that the TK-760G/

762G is in Program mode.

IBM-PC

7. Press F10 on the personal computer. A window opens

on the display to indicate the writing progress. When the

TK-760G/762G starts to receive data, the BUSY/TX LED

lights green.

8. If writing ends successfully, the LED on the TK-760G/

762G goes off and the checksum is displayed.

(Since the TK-762G does not have a display, check the

checksum with the FPU (KPG-56D).)

9. If you want to continue programming other TK-760G/

762G, repeat steps 5 to 8.

Notes :

Note :

• To start the Firmware Programmer from KPG-56D, the

FPRO path must be set up by the KPG-56D setup.

• This mode cannot be entered if the Firmware program-

ming mode is set to Disable in the Programming soft-

ware (KPG-56D).

• When programming the firmware, it is recommend to

copy the data from the floppy disk to your hard disk be-

fore you update the radio firmware.

You can clone the programmed data between the trans-

ceiver listed below. Frequency version must be same.

2. If you press the [A] switch while "PROG 576" is displayed,

the display changes to "PROG 192" to indicate that the

write speed is low speed (19200 bps). If you press the

[A] switch again while "PROG 192" is displayed, the dis-

play changes to "PROG 384", and the write speed be-

comes the middle speed (38400 bps). If you press the

[A] switch again while "PROG 384" is displayed, the dis-

play returns to "PROG 576".

7. Clone Mode

Programming data can be transferred from one radio to

another by connecting them via their modular microphone

jacks. The operation is as follows (the transmit radio is the

master and the receive radio is the slave).

1. Turn the master TK-760G power ON with the [ ] key

held down. The TK-760G displays "CLONE".

2. Power on the slave TK-760G/762G.

Cloning cable

(E30-3382-05)

3. Connect the cloning cable (No. E30-3382-05) to the

modular microphone jacks on the master and slave.

4. Press the [SCN] key on the master while the master dis-

plays "CLONE". The data of the master is sent to the

slave. While the slave is receiving the data, "–PC–" is dis-

played. When cloning of data is completed, the master

displays "END", and the slave automatically operates in

the User mode. The slave can then be operated by the

same program as the master.

5. The other slave can be continuously cloned. When the

[SCN] key on the master is pressed while the master dis-

plays "END", the master displays "CLONE". Carry out the

operation in step 2 to 4.

CIRCUIT DESCRIPTION

■ IF Amplifier

Frequency Configuration

The first IF signal is amplified by Q13, and the enters IC5

(FM processing IC). The signal is heterodyned again with a

second local oscillator signal within IC5 to create a 450kHz

second IF signal. The second IF signal is then fed through a

450kHz ceramic filter (Narrow : CF1, Wide : CF2) to further

eliminate unwanted signals before it si amplified and FM

detected in IC5.

The 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 neces-

sary frequencies. Figure 1 shows the frequencies.

■ Front-end RF Amplifier

An incoming signal from the antenna is applied to an RF

amplifier (Q27) after passing through a transmit/receive

switch circuit (D33 and D34 are off) and a band pass filter

(L18). After the signal is amplified (Q27), the signal is fil-

tered through a band pass filter (L11, L13 and L15) to elimi-

nate unwanted signals before it is passed to the first mixer.

Band pass filters (L18, L11, L13 and L15) have varactor di-

odes (D30, D31, D18, D23 and D28).

CIRCUIT DESCRIPTION

■ Wide/Narrow Changeover Circuit

■ Squelch Circuit

The W/N port (pin 4) of the shift register (IC510) is used

to switch between ceramic filters. When the W/N port is

high, Q4 turns on and the ceramic filter SW diode (D8, D10)

CF1 turns on to receive a Narrow signal. At the same time,

Q35 turns on and one of the filters is selected so that the

wide and narrow audio output levels are equal.

When the W/N port is low, Q3 turns on and the ceramic

filter SW diode (D8, D10) CF2 turns on to receive a Wide

signal.

The detection output from the FM IF IC (IC5) passes

through a band-pass filter and a noise amplifier (Q10) in the

control unit to detect noise. A voltage is applied to the CPU

(IC502). The CPU controls squelch according to the voltage

(ASQ) level. The signal from the RSSI pin of IC5 is moni-

tored. The electric field strength of the receive signal can be

known before the ASQ voltage is input to the CPU, and the

scan stop speed is improved.

PLL Frequency Synthesizer

The PLL circuit generates the first local oscillator signal

for reception and the RF signal for transmission.

■ AF Signal System

The detection signal (DEO) from the TX-RX unit goes to

the audio processor (IC508) of the control unit. The signal

passes through a filter in the audio processor to adjust the

gain, and is output to IC507. IC507 sums the AF signal and

the DTMF signal, BEEP signal and returns the resulting sig-

nal to the TX-RX unit. The signal (AFO) sent to the TX-RX

unit is input to the D/A converter (IC6). The AFO output level

is adjusted by the D/A converter. The signal output from the

D/A converter is input to the audio power amplifier (IC13).

The AF signal from IC13 switches between the internal

speaker and speaker jack (J1) output.

■ PLL

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

16.8MHz reference oscillator signal is divided at IC3 by a

fixed counter to produce the 5 or 6.25kHz reference fre-

quency. The voltage controlled oscillator (VCO) output sig-

nal is buffer amplified by Q106 (Sub-unit), then divided in IC3

by a dual-module programmable counter. The divided signal

is compared in phase with the 5 or 6.25kHz reference signal

in the phase comparator in IC3. The output signal from the

The operating frequency is generated by Q103 in trans-

quency is controlled by applying the VCO control voltage,

obtained from the phase comparator, to the varactor diodes

(D102 and D104 in transmit mode and D101 and D103 in

receive mode). The RX (ST) pin is set low in receive mode

causing Q102 to turn Q103 off, and turn Q101 on. The RX

(ST) pin is set low in transmit mode. The outputs from Q101

and Q103 are amplified by Q106 and sent to the buffer am-

plifiers.

■ Unlock Circuit

Transmitter System

■ Outline

The transmitter circuit produces and amplifies the de-

sired frequency directly. It FM-modulates the carrier signal

by means of a varicap diode

During reception, the 8RC signal goes high, the 8TC sig-

nal goes low, and Q16 turns on. Q18 turns on and a voltage

is applied to the collector (8R). During transmission, the

8RC signal goes low, the 8TC signal goes high and Q29

turns on. Q28 turns on and a voltage is applied to 8T.

The CPU in the control unit monitors the PLL (IC3) LD

signal directly. When the PLL is unlocked during transmis-

sion, the PLL LD signal goes low. The CPU detects this

signal and makes the 8TC signal low. When the 8TC signal

goes low, no voltage is applied to 8T, and no signal is trans-

mitted.

■ Power Amplifier Circuit

The transmit output signal from the VCO is amplified to a

specified level of the power module (IC400) by the drive

block (Q22 and Q25). The amplified signal passes through

the transmission/reception selection diode (D16) and goes

to a low-pass filter. The low-pass filter removes unwanted

high-frequency harmonic components, and the resulting sig-

nal is goes the antenna terminal.

CIRCUIT DESCRIPTION

■ APC Circuit

■ Memory Circuit

The automatic transmission power control (APC) circuit

detects part of a power module output with a diode (D35,

D36) and applies a voltage to IC15. IC15 compares the APC

control voltage (PC) generated by the D/A converter (IC6)

and DC amplifier (IC7) with the detection output voltage to

control Q31 and Q32, generates DB voltage from B voltage,

and stabilizes transmission output.

The transceiver has a 2M-bit (256k x 8) flash ROM

(IC501) and an 8k-bit EEPROM (IC505). The flash ROM con-

tains firmware programs, data and user data which is pro-

grammed with the FPU. The EEPROM contains adjustment

data. The CPU (IC502) controls the flash ROM through an

external address bus and an external data bus. The CPU

controls the EEPROM through two serial data lines.

The APC circuit is configured to protect over current of

the power module due to fluctuations of the load at the an-

tenna end and to stabilize transmission output at voltage

and temperature variations.

transceiver is busy, Q508 turns on and the green LED on

D521 lights. In transmit mode, the LED0 line goes high,

Q504 turns on and the red light lights. Backlighting LEDs for

the key operation unit (D509~D514) and LCD are provided.

When the MBL line goes high, Q506 turns on, then Q505

turns on, and the key illumination LED lights. A voltage is

applied to the MBL line to turn on the LCD backlight.

■ Key Matrix Circuit

The TK-760G/762G front panel has function keys. Each

of them is connected to a cross point of a matrix of the KIN0

to KOUT2 ports of the microprocessor. The KOUT0 to

KOUT2 ports are always high, while the KIN0 to KIN2 ports

are always low.

LCD ASSY

TX-RX UNIT

The microprocessor monitors the status of the KIN0 to

KOUT2 ports. If the state of one of the ports changes, the

microprocessor assumes that the key at the matrix point

corresponding to that port has been pressed.

CIRCUIT DESCRIPTION

■ Encode

■ D/A Converter

The QT and DQT signals are output from TO of the CPU

The D/A converter (IC6) is used to adjust TONE and MO

modulation, AF volume, TV voltage, FC reference voltage,

and PC POWER CONTROL voltage level.

Adjustment values are sent from the CPU as serial data.

The D/A converter has a resolution of 256 and the following

relationship is valid:

(IC502) and summed with the external pin DI line by the

summing amplifier (IC2) and the resulting signal goes to the

D/A converter (IC6) of the TX-RX unit. The DTMF and 2-

TONE signals are output from DTMF of the CPU and goes to

the audio processor (IC508). The signal is summed with a

MIC signal by the audio processor (IC508), and the resulting

signal passes through an analog switch (IC509) and goes to

the TX-RX unit (MO).

D/A output = (Vin – VDAref) / 256 x n + VDAref

Vin: Analog input

VDAref: D/A reference voltage

The D/A converter (IC6) adjusts the MO level and the bal-

ance between the MO and TO levels. Part of a TO signal is

summed with MO and the resulting signal goes to the MD

pin of the VCO. This signal is applied to a varicap diode in

the VCO for direct FM modulation.

n: Serial data value from the microprocessor (CPU)

Power Supply Circuit

When the POWER switch on the control unit is pressed,

the PSW signal goes low. This signal is inverted by Q26 and

sent to a flip-flop IC (IC14). This IC outputs a control signal

when the PSW goes low. When the power turns on, pin 1

of IC14 outputs a low signal and Q20 turns on. The base of

Q19 goes high, Q19 turns on, SB SW (Q23) turns on and

power (SB) is supplied to the set.
