INTRODUCTION
SCOPE OF THIS MANUAL
This 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 publication
date. Changes which may occur after publication are covered
by either Service Bulletins or Manual Revisions, which are
issued as required.
ORDERING REPLACEMENT PARTS
When 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 the
part number is not known, include the chassis or kit number
of which it is a part and a sufficient description of the required
component for proper identification.
PERSONAL SAFETY
The following precautions are recommended for personal
safety :
•DONOT transmit if someone is within two feet (0.6
meter) of the antenna.
•DONOT 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. UNPACKING
Unpack the radio from its shipping container and check for
accessory items. If any item is missing, please contact
KENWOOD immediately.
2. PRE-INSTALLATION CHECKOUT
2-1. Introduction
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.
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 ra-
dio antenna and accessories will be mounted.
Plan cable runs for protection against pinching or crushing
wiring, and radio installation to prevent overheating.
3-2. 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.
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 rec-
ommended.
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.
4. INSTALLATION PLANNING –CONTROL STATIONS
4-1. Antenna system
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.
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.

3-3. KPG-46 Description
(PC programming interface cable : Option)
The KPG-46 is required to interface the transceiver 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
transceiver to the computers RS-232C serial port.
3-4. Programming Software Description
KPG-99D(E) is the programming software for transceiver
supplied on a CD-ROM. This software runs under Windows
98, ME, Windows 2000 or XP on an IBM-PC or compatible
machine.
The data can be input to or read from transceiver and ed-
ited on the screen. The programmed or edited data can be
printed out. It is also possible to tune the transceiver.
4. Clone Mode
Programming data can be transferred from one trans-
ceiver to another by connecting them via their modular micro-
phone jacks. The operation is as follows (the transmit trans-
ceiver is the master and the receive transceiver is the slave).
Note :
Clone mode should be enabled.
1. Turn the master transceiver power ON with the [ ] key
held down (2 seconds), “CLONE” (TK-7160) or “C” (TK-
7162) is displayed on the LCD.
2. Power on the slave transceiver.
3. Connect the cloning cable (No. E30-3382-05) to the modu-
lar microphone jacks on the master and slave.
4. Press the [ ] key on the master transceiver. The data of
the master is sent to the slave. While the master is send-
ing data, red LED blinked. While the slave is receiving the
data, “PROGRAM” (TK-7160) or “P” (TK-7162) is dis-
played and green LED blinked. When cloning of data is
completed, the master displays “END” (TK-7160) or “E”
(TK-7162), and the master red LED turned off, 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. Carry out the
operation in step 2 to 4.

Receiver System
The receiver is double conversion superheterodyne. The
frequency configuration is shown in Figure 1.
■Front-end RF Amplifier Circuit
An incoming signal from the antenna is applied to an RF
amplifier (Q353) after passing through a transmit/receive
switch circuit (D602 and D603 are off) and a band pass filter
(L357, L356 and varactor diodes : D353, D354). After the
signal is amplified (Q353), the signal is filtered through a band
pass filter (L354, L355 and varactor diodes : D351, D352) to
eliminate unwanted signals before it is passed to the first
mixer.
The voltage of these diodes are controlled by tracking the
CPU (IC101) center frequency of the band pass filter. (See
Fig. 2)
■First Mixer Circuit
The signal from the RF amplifier is heterodyned with the
first local oscillator signal from the PLL frequency synthesizer
circuit at the first mixer (Q352) to create a 49.95MHz first
intermediate frequency (1st IF) signal. The first IF signal is
then fed through a monolithic crystal filter (MCF : XF351) to
further remove spurious signals.
■IF Amplifier Circuit
The first IF signal is amplified by Q351, and the enters
IC321 (FM processing IC). The signal is heterodyned again
with a second local oscillator signal within IC321 to create a
450kHz second IF signal. The second IF signal is then fed
through a 450kHz ceramic filter (Wide : CF331, Narrow :
CF332) to further eliminate unwanted signals before it is am-
plified and FM detected in IC321.

■Wide/Narrow Switching Circuit
The Wide port (pin 23) and Narrow port (pin 22) of the CPU
is used to switch between ceramic filters. When the Wide
port is high, the ceramic filter SW diodes (D332, D331) cause
CF331 to turn on to receive a Wide signal.
When the Narrow port is high, the ceramic filter SW di-
odes (D332, D331) cause CF332 to turn on to receive a Nar-
row signal.

■AF Signal System
The detection signal from IF IC (IC321) goes to D/A con-
verter (IC201) to adjust the gain and is output to AQUA IC
(IC241) for characterizing the signal. The AF signal output
from IC241 and the DTMF/MSK signal, BEEP signal are
summed and the resulting signal goes to the D/A converter
(IC201). The AFO output level is adjusted by the D/A con-
verter. The signal output from the D/A converter is input to
the audio power amplifier (IC281). The AF signal from IC281
switches between the internal speaker and speaker jack (J1)
output.

■Squelch Circuit
The detection output from the FM IF IC (IC321) passes
through a noise amplifier (Q301) to detect noise. A voltage is
applied to the CPU (IC101). The CPU controls squelch ac-
cording to the voltage (SQIN) level. The signal from the RSSI
pin of IC321 is monitored. The electric field strength of the
receive signal can be known before the SQIN 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.
■PLL Circuit
The frequency step of the PLL circuit is 5 or 6.25kHz. A
16.8MHz reference oscillator signal is divided at IC401 by a
fixed counter to produce the 5 or 6.25kHz reference fre-
quency. The voltage controlled oscillator (VCO) output signal
is buffer amplified by Q446, 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 the
phase comparator in IC401. 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. 6)
■VCO Circuit
The operating frequency is generated by Q444 in transmit
mode and Q441 in receive mode. The oscillator frequency is
controlled by applying the VCO control voltage, obtained
from the phase comparator, to the varactor diodes (D443 and
D444 in transmit mode and D441 and D442 in receive mode).
The TX/RX pin is set low in receive mode causing Q443 and
Q442 to turn Q444 off, and turn Q441 on. The TX/RX pin is
set high in transmit mode. The outputs from Q441 and Q444
are amplified by Q446 and sent to the RF amplifiers.

■Unlock Circuit
During reception, the 8RC signal goes high, the 8TC signal
goes low, and Q44 turns on. Q43 turns on and a voltage is
applied to the collector (8R). During transmission, the 8RC
signal goes low, the 8TC signal goes high and Q46 turns on.
Q45 turns on and a voltage is applied to 8T.
The CPU in the control unit monitors the PLL (IC401) LD
signal 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 goes
low, no voltage is applied to 8T, and no signal is transmitted.
Transmitter System
■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 passes through
the transmission/reception selection diode (D448) and ampli-
fied by Q501 and Q502. The amplified signal goes to the RF
power module (IC502) 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 Circuit
The automatic transmission power control (APC) circuit
detects part of a final amplifier output with a diode (D606,
D607 and D608) and applies a voltage to IC651. IC651 com-
pares the APC control voltage (PC) generated by the D/A con-
verter (IC201) and DC amplifier (IC214) with the detection
output voltage. IC651 generates the voltage to control Q502
and IC502 and stabilizes transmission output.
The APC circuit is configured to protect over current of
Q502 and IC502 due to fluctuations of the load at the antenna
end and to stabilize transmission output at voltage and tem-
perature variations.

■ Display Circuit
The CPU (IC101) controls the display LCD and LEDs.
When power is on, the CPU will use the MBL line to control
the LCD illumination and key backlight LEDs.
The dimmer function is controlled by the switch Q1*. The
LCD controller (IC1) controls the functions of the LCD
through the DO, CE, CL, DI lines from the CPU.
■Key Matrix Circuit
The TK-7160/7162 front panel has function keys. the TK-
7162 terminal name are parenthese inside. Each of them is
connected to a cross point of a matrix of the KMI1 (KI3) to
KMO3 (KS4) ports of the IC1 LCD driver. The KMO1 (KS2) to
KMO3 (KS4) ports are always high, while the KMI1 (KI3) to
KMI3 (KI1) ports are always low.
The microprocessor monitors the status of the KMI1 (KI3)
to KMO3 (KS4) 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.

Signaling Circuit
■Encode
•Low-speed data (QT, DQT)
Low -speed data is output from pin 1 of the CPU (IC101).
The signal passes through a low-pass CR filter. The signal is
mixed with the audio signal and goes to the VCO and TCXO
(X401) modulation input after passing through the D/A con-
verter (IC201) for BAL adjustment.
•High-speed data (5-tone, DTMF)
High-speed data (HSD) is output from pin 2 of the CPU.
The signal passes through a low-pass CR filter. TX deviation
making an adjustment by microprocessor is passed through
the switch (IC213) and then applied to the audio processor
(IC241). The signal is mixed with the audio signal and goes to
the VCO and TCXO.
The RX tone is passed a summing amplifier (IC241). The
D/A converter (IC201) for audio control, audio power amplifier
and then to the speaker.
•MSK
MSK signal is output from pin 6 of IC241. The signal
passes through the D/A converter (IC201) for the MSK devia-
tion adjustment, and is routed to the VCO. When encoding
MSK, the microphone-input signal is muted.

■Decode
•Low-speed data (QT, DQT)
The demodulated signal from the FM IC (IC321) is passed
through a low-pass filter (IC211 1/2) to remove frequency of
300Hz or more.
The signal is input to pin 88 of the CPU. The CPU digitizes
this signal, performs processing such as DC restoration, and
decodes the signal.
•High-speed data (DTMF)
The DTMF input signal from the IF IC is amplified by IC241
and goes to the DTMF decoder in the IC241. The CPU then
processes the decoded information.
•High-speed data (5-tone)
The demodulated signal from the IF IC (IC321) is amplified
by IC241 and passes through a high-pass filter to remove fre-
quency of 300Hz or less. The CPU digitizes this signal and
decodes the signal.

Power Supply Circuit
When 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 78 (SBC) goes high, Q42 turns
on, SB SW (Q31) turns on and power (SB) is supplied to the
radio.
When the DC power supplied to the radio, the voltage
regulator IC (IC43) supply into the CPU VDD and reset voltage
detect IC (IC44). IC44 will generate signal (RESET) in to the
reset terminal on the CPU (IC101) to carry out a power ON
reset. Also, CPU (IC101) is checking on port 91 (BATT). If DC
power is less than about 9.5V, the radio is unable to power
on.
When the DC power voltage deceases from normal volt-
age, the INT voltage detector IC (IC45) will set to high on CPU
port 18 (INT). If B line becomes less than about 9.5V, CPU
will send the backup data to EEPROM (IC81) and go into
STOP mode.
This circuit has an overvoltage protection circuit. If a DC
voltage of 16V or higher is applied to the base of Q81, this
voltage turns Q81 on and sets port 18 (INT) to low. As a
result port 78 (SBC) is low, and turns Q42 and Q31 (SB) off.
