INTRODUCTIONSCOPE 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 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 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 SAFETYThe following precautions are recommended for personal

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 CONSIDERATIONS1. UNPACKING

Unpack the radio from its shipping container and check for

accessory items. If any item is missing, please contact

KENWOOD immediately.

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

installation (mobile or base) be obtained by the equipment

owner. The licensee is responsible for ensuring transmitter

power, 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 general

class commercial radiotelephone operator’s license. There is

no 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 should

be checked, as should receiver sensitivity, squelch operation,

and audio output. Signalling equipment operation should be

verified.

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. The

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

using 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 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 wiring1. 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.

5. INSTALLATION PLANNING – CONTROL STATIONS

5-1. Antenna systemControl 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.

5-2. Radio locationSelect 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.

SERVICEThis radio is designed for easy servicing. Refer to the

schematic diagrams, printed circuit board views, and align-

ment procedures contained in this manual.

Fig. 1 Frequency configuration

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/receive

switch circuit (D603 and D605 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 MixerThe 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 one pair of monolithic crystal filter (MCF :

XF351) to further remove spurious signals.

IF AmplifierThe 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 : CF301, Narrow :

CF302) to further eliminate unwanted signals before it is am-

plified and FM detected in IC321.

Wide/Narrow Switching CircuitThe 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

CF301 to turn on to receive a Wide signal.

When the Narrow port is high, the ceramic filter SW di-

odes (D332, D331) cause CF302 to turn on to receive a Nar-

row signal.

AF Signal SystemThe 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 CircuitThe 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 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 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)

VCOThe 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 CircuitDuring 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 CircuitThe transmit output signal from the VCO passes through

the transmission/reception selection diode (D448) and ampli-

fied by Q501, Q502 and Q503. The amplified signal goes to

the 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 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,

Q503 and Q504 and stabilizes transmission output.

The APC circuit is configured to protect over current of

Q502, Q503 and Q504 due to fluctuations of the load at the

antenna end and to stabilize transmission output at voltage

and temperature variations.Fig. 7 Unlock circuit

1) Controls the WIDE, NARROW, TX/RX outputs.

2) Controls the AQUA IC (IC241).

3) Controls the PLL (IC401).

4) Controls the D/A converter (IC201) and adjusts the vol-

ume, modulation and transmission power.

Memory CircuitThe transceiver has an 64k-bit EEPROM (IC81). The

EEPROM contains adjustment data. The CPU (IC101) con-

trols the EEPROM through three serial data lines.

Display CircuitThe 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 CircuitThe TK-7160 front panel has function keys. Each of them

is connected to a cross point of a matrix of the KMI1 to KMO3

ports of the IC1 LCD driver. The KMO1 to KMO3 ports are

always high, while the KMI1 to KMI3 ports are always low.

The microprocessor monitors the status of the KMI1 to

KMO3 ports. If the state of one of the ports changes, the

microprocessor assumes that the key at the matrix point cor-

responding to that port has been pressed.

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

CPU (IC101) and summed with the external pin DI line by the

AQUA IC (IC241) and the resulting signal goes to the D/A con-

verter (IC201). The DTMF signal is output from DTMF of the

CPU and goes to the D/A converter (IC201). The signal is

summed with a MIC signal by the AQUA IC (IC241), and the

resulting signal goes to the D/A converter (IC201).

The D/A converter (IC201) adjusts the MO level and the

balance between the MO and QT/DQT levels. Part of a QT/

DQT signal is summed with MO and the resulting signal goes

to the VCOMOD pin of the VCO. This signal is applied to a

varicap diode in the VCO for direct FM modulation.

DecodeThe signal goes to EXTLIMIN (pin 5) of AQUA IC (IC241).

The QT/DQT signal will pass through the low-pass filters in

the AQUA IC (IC241) and be decoded within the AQUA IC

(IC241). The DTMF signal will be decoded within the AQUA

IC (IC241).

D/A ConverterThe D/A converter (IC201) is used to adjust MO modula-

tion, 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

n: 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 78 (SBC) goes high, Q42 turns

on, SB SW (Q41) 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 will became less than about 9.5V. Then

CPU send to EEPROM (IC81) the backup data 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 Q41 (SB) off.

If normal power is not obtained, please follow the

step belowOpen the shielding cover (upper), and screw 3 locations

around ANT pin.

1. Switch off the transceiver.

Impedance of Final FET (Q504) and Drive FET (Q503) can

be measured easily using DVM Ω mode.

Normal condition – Gate : 20kΩ~50kΩ, Drain : 1MΩ~2MΩ

The 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. The

voltage will be 12.6V~ in transmitting condition. If found

0V at this point then F501 is broken.

3. Remove R517.

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 FET

gate 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 of

0.3W~0.6W.

If power found is less than 0.3W, check the circuit before

the Drive FET.
