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.

GENERAL
2. PRE-INSTALLATION CHECKOUT
2-1. Introduction
4. INSTALLATION PLANNING – CONTROL STATIONS
4-1. Antenna system
Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation 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 system that will best serve your particular needs.
2-2. Testing
The 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
should be checked, as should receiver sensitivity, squelch
operation, and audio output. Signalling equipment operation
should be verified.
3. PLANNING THE INSTALLATION
3-1. General
Inspect the vehicle and determine how and where the
radio antenna and accessories will be mounted.
Plan cable runs for protection against pinching or crushing wiring, and radio installation to prevent overheating.
4-2. Radio location
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.
SERVICE
This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and alignment procedures contained in this manual.
3-2. Antenna
Note
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 setup, take the following precaution.
The rating of pin 7 (SB) of the accessory connector cable
(KCT-19) on the rear of the radio is 13.2V (1A). Insert a 1A
fuse if you use the SB pin for external equipment.
3-3. Radio
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.

3-4. 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 installation 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 recommended.
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.
If you do not intend to use the 3.5-mm jack for the external speaker, fit the supplied speaker-jack cap (B09-0235-05)
to stop dust and sand getting in.

normal receive mode (PTT off).
When you activate the key programmed to the scan function, the scan starts. The scan icon “SCN” lights and
“SCAN” is indicated on alphanumeric display.
■ Scan stop condition
The scan stops temporarily if the following conditions are
satisfied.
1) A carrier is detected, then signalling matches on channels for which receive the signalling is set by the programming 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.
TK-760G/(N)/762G/(N)
OPERATING FEATURES
■ 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 channel 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 example 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 temporarily to scan sequence, select the desired (deleted) channel
during scan, activate the delete/add function (for example
press the key) before scan re-start.
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.
■ Priority channel setting
A priority channel can be set as follows with the programming software (KPG-67D).
1) Specify a priority channel as a fixed priority channel.
2) Make a selected channel, a priority channel.
■ 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.
2) When priority channel is set : Either priority channel is
scanned.
If a non-priority channel stops temporarily, a priority channel signal is detected at certain intervals.
If a priority channel stops temporarily, it stops until there
is no signal on the priority channel.
■ Revert channel
The revert channel is used to transmit during scanning
and set by the programming software (KPG-67D).
1) Priority
The transceiver reverts to the priority channel.
2) Priority with talkback
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 current channel to answer to the call however revert channel
is set to priority channel.
After resume time, scan re-starts and transmission channel is return to priority channel.
3) Selected channel
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.
4) Last called channel
The transceiver reverts to the last called channel during
the scan.
5) Last used channel
The transceiver reverts to the last used (transmitted)
channel during scan. “Last used” revert channel includes talkback function.
6) Selected with talkback
The transceiver reverts to the channel before scanning or
the channel that you changed during scan.
■ Scan end
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 transmitter 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.
■ 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 programmable.
BOT : DTMF ID (BOT) is sent on beginning of transmission.
EOT : DTMF ID (EOT) is sent on end of transmission.
Both : DTMF ID (BOT) is sent on beginning of transmission and DTMF ID (EOT) is sent on end of transmission.
■ Radio password (TK-760G only)
When the password is set in the transceiver, user can not
use the transceiver unless enter the correct password.
This code can be up to 6 digits from 0 to 9 and input with
the key, and “SCN” key.
■ Off hook decode
If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no
effect for decoding QT/DQT and option signalling.
■ “TOT” pre-alert
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.
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.

TK-760/G(N)/762G/(N)
OPERATING FEATURES
■ “TOT” re-key time
■ Dead Beat Disable
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.
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 appear.
■ “TOT” reset time
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.
■ Clear to transpond
The transceiver waits the transpond of 5-tone/2-tone /
DTMF if channel is busy until channel open. This feature
prevents the interference to other party.
6. Option Signalling (DTMF/2-Tone)
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.
The orange LED will flash.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute QT/DQT/Carrier.
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.
■ Power on tone
This tone is output when the transceiver is turned on.
(The high tone is output for 500ms.)
■ Alert tone
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.
■ AND/OR
■ Busy tone
You can select AND or OR for option signalling match
conditions.
Sounds in conventional mode, when busy channel lockout is functioning. You can select yes or no for the optional
feature’s warning tone.

5. PC Mode
5-1. Preface
The TK-760G/762G transceiver is programmed using a
personal computer, a programming interface (KPG-46) and
programming software (KPG-67D).
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 entered immediately. When the PC sends a command, the
radio enters PC mode.
When data is transmitted from transceiver, the red LED
blink.
When data is received by the transceiver, the green LED
blink.
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.
5-3. KPG-46 Description
(PC programming interface cable : Option)
The KPG-46 is required to interface the TK-760G/762G
with the computer. It has a circuit in its D-subconnector (25pin) 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.
KPG-46

KPG-67D
TK-760G/762G
Fig. 1

The KPG-67D is programming software for the transceiver supplied on two 3.5" floppy disks. This software runs
under MS-DOS 3.1 or later on an IBM-PC or compatible machine.
The data can be input to or read from the transceiver and
edited on the screen. The programmed or edited data can
be printed out. It is also possible to tune the transceiver.
We recommend that install the KPG-67D for example to
harddisk first then use it.
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 features are released in the future. (For details on how to obtain the firmware, contact Customer Service.)
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.)
6-3. Programming
1. Start up the programming software (KPG-67D), 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. Turn the TK-760G/762G Power ON with the [CH ]
switch held down. Hold the switch down for two seconds until the display changes to “PROG 576”, the
BUSY/TX LED lights orange. When “PROG 576” appears, release your finger from the switch.
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.
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-67D).)
9. If you want to continue programming other TK-760G/
762G, repeat steps 5 to 8.
TK-760G/(N)/762G/(N)
REALIGNMENT
Notes :
• To start the Firmware Programmer from KPG-67D, the
FPRO path must be set up by the KPG-67D setup.
• This mode cannot be entered if the Firmware programming mode is set to Disable in the Programming software (KPG-67D).
• When programming the firmware, it is recommend to
copy the data from the floppy disk to your hard disk before you update the radio firmware.
Directly copying from the floppy disk to the radio may not
work because the access speed is too slow.

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 display changes to “PROG 384”, and the
write speed becomes the middle speed (38400 bps). If
you press the [A] switch again while “PROG 384” is displayed, the display returns to "PROG 576".

Connect the cloning cable (No. E30-3382-05) to the
modular microphone jacks on the master and slave.
Press the [SCN] key on the master while the master displays “CLONE”. The data of the master is sent to the
slave. While the slave is receiving the data, “–PC–” is
displayed. 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.
The other slave can be continuously cloned. When the
[SCN] key on the master is pressed while the master displays “END”, the master displays “CLONE”. Carry out
the operation in step 4 to 6.

CIRCUIT DESCRIPTION
■ IF Amplifier
Frequency Configuration
The receiver utilizes double conversion. The first IF is
49.95MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the necessary frequencies. Figure 1 shows the frequencies.
ANT
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 (CF2) to further eliminate unwanted
signals before it is amplified and FM detected in IC5.

(L18). After the signal is amplified (Q27), the signal is filtered through a band pass filter (L11, L13 and L15) to eliminate unwanted signals before it is passed to the first mixer.
Band pass filters (L18, L11, L13 and L15) have varactor diodes (D30, D31, D18, D23 and D28).
The voltage of these diodes are controlled by to track the
CPU (IC502) center frequency of the band pass filter. (See

CIRCUIT DESCRIPTION
■ AF Signal System
PLL Frequency Synthesizer
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 signal 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.
The PLL circuit generates the first local oscillator signal
for reception and the RF signal for transmission.
■ 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 frequency. The voltage controlled oscillator (VCO) output signal 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
phase comparator is filtered through a low-pass filter and
passed to the VCO to control the oscillator frequency. (See
Fig. 5)

■ VCO
DTMF
The TK-760G/762G has VCO in a Sub-unit (A1) housed in
a solid shielded case and connected to the TX-RX unit
through CN101.
The operating frequency is generated by Q103 in transmit mode and Q101 in receive mode. The oscillator frequency 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 amplifiers.
FIg. 3 AF signal system
■ Squelch Circuit
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 monitored. 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.

CIRCUIT DESCRIPTION
■ Unlock Circuit
During reception, the 8RC signal goes high, the 8TC signal 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 transmission, 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 transmitted.

■ Outline
The transmitter circuit produces and amplifies the desired frequency directly. It FM-modulates the carrier signal
by means of a varicap diode
■ 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 signal is goes the antenna terminal.
■ APC 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 APC circuit is configured to protect over current of
the power module due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage
and temperature variations.

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.
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.

■ Memory Circuit
The transceiver has a 2M-bit (256k x 8) flash ROM
(IC501) and an 8k-bit EEPROM (IC505). The flash ROM contains firmware programs, data and user data which is programmed 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.

■ Display Circuit
The CPU (IC502) controls the shift register (IC510) and
display LEDs. When the LED1 line goes high when the
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.

■ Encode
The QT and DQT signals are output from TO of the CPU
(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 2TONE 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).
The D/A converter (IC6) adjusts the MO level and the balance 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.

CIRCUIT DESCRIPTION
■ Decode
• QT/DQT/DTMF
■ PA Switch
The signal (DEO) detected by the TX-RX unit passes
through two low-pass filters of IC513, goes to TOI of the
CPU (IC502) to decode QT, DQT. The DTMF signal is decoded by a dedicated IC (IC511) and the resulting signal is
sent to the CPU (IC502) as serial data.
• 2-tone, 5-tone
The detected signal passes through audio processor
(IC508) RX OUT. Then it is filtered through IC514 2-stage
low-pass filtered to enter CPU (IC502) to decode 2-tone and
5-tone signalling.

If the optional KAP-1 is used (see the separate section for
details), the PA (Public Address) function becomes available.
In this case, the signal flow changes as follows;
• PA off
For TX, the switch which is between pins 10 and 11 of
IC509 closes. The audio signal from the microphone passes
through IC509 and IC6 and modulates the VCO.
For RX, the switch which is between pins 3 and 4 of
IC509 closes. The detected signal passes through IC509,
IC508, IC507, IC6 and IC13 and is then output to the
speaker.
• PA on
Since the switch which is between pins 10 and 11 of
IC509 is open, the switch which is between pins 3 and 4 of
IC509 is open, and the switch which is between pins 1 and 2
of IC509 is closed, the audio signal from the microphone
passes through IC508, IC507 and IC6, and then goes to
IC13. The signal is output to the external PA system
through the PA relay in KAP-1.

■ D/A Converter
OP AMP
The horn switch, consisting of Q1, Q5, and Q6, controls
the horn relay. It is supplied by the dealer to provide the
external horn alert function.
Q6 disables horn alert, turning on when its base is high,
to inhibit the function. Normally, the output from IC9 is low,
and Q5 is off; the base of Q1 is about 0V and Q1 is off.
When horn alert is enabled, the output from IC9 goes high
and Q5 turns on. The base current flows through R21 to Q1
to turn Q1 on. Q1 can sink a maximum of 100mA. If the
optional KAP-1 is used, it can drive up to 2A.

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.
This circuit has an overvoltage protection circuit. If a DC
voltage of 20 V or higher is applied to the power cable, D21
turns on and a voltage is applied to the base of Q21. This
voltage turns Q21 on and turns Q19 and SBSW off.

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:
D/A output = (Vin – VDAref) / 256 x n + VDAref
Vin: Analog input
VDAref: D/A reference voltage
