INTRODUCTION 

SCOPE OF THIS MANUAL 

This manual is intended for use by experienced technicians 

familiar with similar types of commercial grade communications 

equipment. It contains all required service information 

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 information, 

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 : 

• 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 powerup 

for safe operation. 

• This equipment should be serviced by only qualified technicians. 

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. LICENSING REQUIREMENTS 

Federal 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 permitted 

by the station license. 

Transmitter adjustments may be performed only by a licensed 

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. Introduction 

Each radio is adjusted and tested before shipment. However, 

it is recommended that receiver and transmitter operation 

be checked for proper operation before installation. 

3-2. 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. 

4. PLANNING THE INSTALLATION 

4-1. 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. 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. 

4-3. 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. 

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 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. 

5. INSTALLATION PLANNING – CONTROL STATIONS 

5-1. 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. 

5-2. 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.

5-3. 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. 

5-4. Programming software KPG-89D description 

The KPG-89D is the programming software for the transceiver 

supplied on a CD-ROM. This software runs under MS- 

Windows 98, ME, Windows 2000 or XP 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. 

6. Firmware Programming Mode 

6-1. Preface 

Flash memory is mounted on the transceiver. This allows 

the transceiver 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 transceiver to the personal computer (IBM 

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

is the same as in the PC Mode.) 

Note : 

You can only program firmware from the 8-pin microphone 

connector on the front panel. Using the 25-pin logic 

interface on the rear panel will not work. 

6-3. Programming 

1. Start up the firmware programming software (Fpro.exe). 

2. Set the communications speed (normally, 115200 bps) 

and communications port in the configuration item. 

3. Set the firmware to be updated by File name item. 

4. Turn the transceiver power ON with the [S] key held 

down. Then, the orange LED on the transceiver lights and 

“PROG 115200” is displayed. 

5. Check the connection between the transceiver and the 

personal computer, and make sure that the transceiver is 

in the Program mode. 

6. Press write button in the window. When the transceiver 

starts to receive data, the [PG] display is blinking. 

7. If writing ends successfully, the checksum is calculated 

and a result is displayed. 

8. If you want to continue programming other transceivers, 

repeat steps 4 to 7. 

Notes: 

• This mode cannot be entered if the Firmware Programming 

mode is set to Disable in the Programming software. 

• When programming the firmware, it is recommend to 

copy the data from the floppy disk to your hard disk before 

update the radio firmware. 

Directly copying from the floppy disk to the radio may not 

work because the access speed is too slow. 

6-4. Function 

1. If you press the [■ ] key while “PROG 115200” is displayed, 

the display changes to “PROG 19200” (The LED

CIRCUIT DESCRIPTION 

1. Outline 

The TK-7180 is a VHF/FM transceiver designed to operate 

in the frequency range of 136 to 174MHz. Transmission output 

power is 30 watts. The maximum channel capacity is 

512. 

The unit consists of receiver, transmitter, phase-locked 

loop (PLL) frequency synthesizer, and control circuits. 

2. Receiver Circuit 

The receiver is double conversion superheterodyne, designed 

to operate in the frequency range of 136MHz to 

174MHz. 

The receiver circuit consists of the following : 2-1 frontend 

circuit, 2-2 first mixer, 2-3 IF amplifier circuit, 2-4 audio 

amplifier circuit, and 2-5 squelch circuit. 

2-1. Front-end Circuit 

The front-end circuit consists of former BPF (D11), RF amplifier 

Q103, and latter BPF (D103, D104, D105 and D106). 

The BPF covers frequency ranges 136 to 174MHz. 

The latter BPF (D103, D104, D105 and D106) attenuates 

the unwanted signals, and sends only the necessary signal to 

the first mixer.

2-2. First Mixer 

The signal from the BPF is heterodyned with the first local 

oscillator signal from the PLL frequency synthesizer circuit at 

the first mixer DBM (IC171) to become a 44.85MHz first intermediate 

frequency (IF) signal. The first IF signal is fed 

through a monolithic crystal filter (XF171) to further remove 

spurious signals. 

2-3. IF Amplifier 

The first IF signal is amplified by Q171 and Q172, and then 

enters IC172 (FM system IC). The signal is heterodyned 

again with a second local oscillator signal (44.395MHz) with 

in IC172 to become a 455kHz second IF signal. The second 

IF signal is fed through a 455kHz ceramic filters (CF172; 

Wide, CF171; Narrow) to further eliminate unwanted signal, 

and the quadrature detection circuit FM-detects the signal to 

produce a base-band signal and output it from pin 9. 

2-4. Audio Amplifier 

The demodulated audio signal from IC172 goes to IC415 

through the AF amplifier (IC412) and IC413. The audio signal 

goes to an electronic volume (IC410) and is amplified to drive 

a loudspeaker by an audio power amplifier (IC417). The audio 

output can be provided to external 4Ω speaker through the 

speaker jack output (J401) on the rear panel. Q419 is a mute 

switch.

2-5. Squelch Circuit 

The output signal from IC172 enters FM IC again, then 

passed through a band-pass filter. 

The noise component output from IC172 is amplified by 

Q175 and rectified by D173 to produce a DC Voltage corresponding 

to the noise level. The DC voltage is sent to the 

analog port of the CPU (IC404). 

IC172 outputs a DC voltage (RSSI) corresponding to the 

input of the IF amplifier. 

3. Transmitter Circuit 

The transmitter circuit consists of the following circuits : 3- 

1 microphone circuit, 3-2 modulation level adjustment circuit, 

3-3 driver and final power amplifier circuit, and 3-4 automatic 

power control circuit. 

3-1. Microphone Circuit 

The audio signal from the microphone goes into TX-RX 

unit (X57-698) from the display unit (X54-348) and passes 

through the mute switch (Q416). The audio signal is amplified 

by the microphone amplifier (IC414) and is input into the 

TXIN terminal of the audio processor (IC415) after passing 

through the multiplexer (IC413). 

The input audio signal is output from the MOD terminal of 

the audio processor (IC415) and is amplified by the audio frequency 

amplifier (IC412) after passing through the electric 

volume (IC410). 

DISPLAY UNIT

TX-RX UNIT (X57-698) 

3-2. Modulation Level Adjustment Circuit 

The audio signal amplified by the audio frequency amplifier 

(IC412) is added to the low speed data LSD passed 

through the low pass filter (IC409). The combined signals is 

supplied to the VCO (voltage controlled oscillator) and the 

VCXO (voltage controlled crystal oscillator) X301, respectively. 

3-3. Driver and Final Power Amplifier Circuit 

The transmit signal obtained from the TX VCO buffer amplifier 

Q311, is amplified to approximately +17dBm by the 

driver amplifiers Q313, Q1 and Q2. This amplified signal is 

passed to the power amplifier module (power module) IC1, 

which consists of a MOS-FET amplifier and is capable of 

transmission output power. 

3-4. Automatic Power Control Circuit 

The automatic transmission power control (APC) circuit 

stabilizes the transmitter output power at a predetermined 

level by detecting the power module output with a diodes 

D6, D7 and D8. Diodes D6, D7 and D8 apply a voltage to DC 

amplifier IC72 (A/2). IC72 (B/2) compares the APC control 

voltage (PC) generated by microprocessor IC404 and DC amplifier 

IC71 (A/2, B/2) with the detection output voltage 

from IC72 (A/2) to control the Vgg pin of IC1, 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.

4. Frequency Synthesizer Unit 

4-1. Frequency Synthesizer 

The frequency synthesizer consists of the TCXO (X301), 

VCO, PLL IC (IC301) and buffer amplifiers. 

The TCXO generates 16.8MHz. The frequency stability is 

2.5ppm within the temperature range of –30 to +60°C. The 

frequency tuning and modulation of the TCXO are done to 

apply a voltage to pin 1 of the TCXO. The output of the TCXO 

is applied to pin 8 of the PLL IC. 

The VCO consists of 2VCO and covers a dual range of the 

180.85~218.85MHz and the 136~174MHz. The VCO generates 

180.85~218.85MHz for providing to the first local signal 

in receive. The operating frequency is generated by Q307 in 

transmit mode and Q306 in receive mode. The oscillator frequency 

is controlled by applying the VCO control voltage, obtained 

from the phase comparator (IC301) to the variable capacitor 

diodes (D306, D308, D310 and D311 in transmit 

mode and D307, D309, D312 and D313 in receive mode). 

The T/R pin of IC404 goes “high” in receive mode causing 

Q307 and Q309 to turn off, and Q306, Q308 and Q310 turn 

on. The T/R pin goes “low” in transmit mode. 

The outputs from Q306 and Q307 are amplified by buffer 

amplifier (Q311) and doubled by Q301 and then sent to PLL 

IC. 

The PLL IC consists of a prescaler, reference divider, 

phase comparator, charge pump (The frequency step of the 

PLL circuit is 10, 12.5 or 15kHz). The input signal from the 

pins 8 and 5 of the PLL IC is divided down to the 10, 12.5 or 

15kHz and compared at phase comparator. The phase comparator 

output signal is fed into a low-pass filter (Q302, Q303 

and Q304) before being applied to the VCO as a frequency 

control voltage. This low-pass filter’s power is supplied by 

the DC/DC converter (IC251 and Q251). The DC signal is applied 

to the CV of the VCO and locked to keep the VCO frequency 

constant. 

PLL data is output from DT (pin 112), PCK (pin 82) and PLE 

(pin 81) of the microprocessor (IC404). The data are input to 

the PLL IC when the channel is changed or when transmission 

is changed to reception and vice versa. A PLL lock condition 

is always monitored by the pin 80 (UL) of the microprocessor. 

When the PLL is unlocked, the UL goes low.

5. Control Circuit 

The block diagram of the control circuit is shown in Figure 

5. 

The CPU (IC404) is a 16-bit microcomputer that contains a 

256k-byte Mask ROM and a 20k-byte RAM. This CPU is connected 

with an external 512k-byte Flash ROM (IC405) and 

operates in memory expansion mode. 

The Firmware Program is stored in the Flash ROM and the 

user data and adjustment data are stored in the EEPROM 

(IC401). The CPU and Flash ROM are connected with an 8 bit 

bus and the EEPROM and RTC IC (IC402) are connected with 

a I2C bus (*1). The RTC IC (IC402) has a clock function and is 

controlled by the CPU (IC404). 

Serial communication with a PC is performed through two 

paths: through the 232C Level converter IC (IC416) and 

through the Display Unit Panel CPU (IC902). The 8 bit Shift 

Register (IC403) is used as an 8-port Extended Output Port. 

IC410 is an 8 bit-8ch D/A converter. The channels are set as 

follows: 

Ch1 : Modulation balance 

Ch2 : Deviation Factor 

Ch3 : Max Power Level 

Ch4 : Reception tuning circuit 

Ch5 : Deviation Factor 

Ch6 : Speaker volume 

Ch7 : VCXO control voltage

6. Power Supply Circuit 

The block diagram of the power supply circuit is shown in 

Figure 6. 

Power is always supplied from +B to the circuit (5M, +B) 

that is always started and the circuits (SB, 8C, 5E, 8T, 8R, 5C, 

5R) controlled by the CPU (IC404). When +B is supplied to 

the transceiver, Q801, D805 and IC805, regulate the voltage 

(5M) which is supplied to the circuit around the CPU. The 

CPU starts. 

When the CPU detects that the +B voltage is higher than 

the voltage prescribed by IC802, the transceiver power (SB) 

is turned ON by controlling the SBC signal (Low: transceiver 

power OFF, High: transceiver power ON). 

The CPU controls the TXC signal (Low: Transmission system 

power OFF, High: Transmission system power ON) during 

transmission to supply power (8T) to the transmission circuit. 

The CPU controls the RXC signal (Low: Reception system 

power OFF, High: Reception system power ON) during 

reception to supply power (8R, 5R) to the reception circuit. 

When the CPU detects the PSW (Power Switch) signal, 

IGN (Ignition Sense) signal or INT signal, it controls the SBC 

signal and turns the transceiver power (SB) OFF. 

If +B is not provided to the transceiver, power is supplied 

to only the RTC IC (IC402) through the secondary battery connected 

with CN401 to back up the clock. 

7. Display Circuit 

The display unit consists of the Panel CPU (IC902), the 

LCD driver (IC903), the TX/BUSY LED, the KEY detection, the 

Backlight and the Microphone jack circuits. 

The Panel CPU is a 16-bit microcomputer that contains a 

64k-byte Mask ROM and a 2k-byte RAM. 

The Panel CPU performs serial communication with the 

Main CPU (IC404) on the TX-RX unit (B/3) and the Panel CPU 

detects keys and sends data communication contents 

through the MIC Jack to the Main CPU. The Panel CPU receives 

commands from the Main CPU and controls the display 

system. 

The LCD operates with 1/9 duty under the LCD driver 

(IC903) control. The LCD and KEY Backlights are controlled 

by Q909. The display brightness of the LCD Backlight can be 

changed.

Panel Tuning Mode 

■ Preparations for tuning the transceiver 

Before attempting to tune the transceiver, connect the 

unit to a suitable power supply. 

Whenever the transmitter is turned, the unit must be connected 

to a suitable dummy load (i.e. power meter). 

The speaker output connector must be terminated with a 

4Ω dummy load and connected to an AC voltmeter and an 

audio distortion meter or a SINAD measurement meter at all 

times during tuning. 

■ Transceiver tuning 

(To place transceiver in tuning mode) 

Press [S] key, now in tuning mode. Use [B] key to write 

tuning data through tuning modes, and [ ]/[ ] to adjust tuning 

requirements (1 to 256 appeares on LCD). 

Use [C] key to select the adjustment item through tuning 

modes. Use [A] key to adjust 3 or 5 reference level adjustments, 

and use [■] key to switch between Wide 5k/Wide 4k/ 

Narrow. 

Channel appears on LCD. Set channel according to tuning 

requirements.
