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 the publication data. Changes which may occur after publication are
covered by either Service Bulletins or Manual Revisions.
These 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, or 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.
PERSONNEL SAFETY
The following precautions are recommended for personnel safety :
• DO NOT transmit if someone is within two feet (0.6
meter) of the antenna.
• DO NOT transmit until all RF connectors are verified secure and any open connectors are properly terminated.
• SHUT OFF and DO NOT operate this equipment near
electrical blasting caps or in an explosive atmosphere.
• All equipment should be properly grounded before
power-up for safe operation.
• This equipment should be serviced by a qualified technician only.
NOTE
The terms, “Wide” and “Semi wide” this service
manual, are same as “Wide 5k” and “Wide 4k” in the KPG60D (Field Programming Unit) menu and help text, respectively.
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. QT 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.
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 recommended.
CAUTION
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. PRE-INSTALLATION CHECKOUT
2-1. 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.
2
If DC power is to be controlled by the vehicle ignition
switch, a switching relay should be used to switch the positive power lead. The vehicle ignition switch then controls
DC to the relay coil.
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.

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.
■ Keypad operation
This parameter selects the default use of the numerical
field of the keypad. You can select from "DTMF", "Selcall
entry", "Status entry" and "OST".

The time-out timer can be programmed off or in 30 seconds increments from 30 seconds to five 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.
■ Sub LCD display
You can use 3-digit the display to display the channel
number or group number. It is useful when the main (12digit) display indicates group or channel name or other functions.
■ Selective call alert LED
You can select whether or not the LED on the transceiver
flashes in an orange color when selective call was occurred.
■ PTT ID
PTT ID provides a DTMF or FFSK (DMS : Fleet-ID) ANI to
be sent with every time PTT (beginning of transmission, end

AND/OR logic.
AND
OR
■ "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.
■ "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.
■ OST (Operator Selectable Tone)
The transceiver is capable to have "OST" function and 16
tone pair (QT/DQT) with max 10-digit name for each tone
pair.
• "OST" back up
The transceiver is programmable the selected "OST"
code is memorized or not. If you set to Disable (no memorized), the "OST" function always starts at "off".
■ 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.
5. 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, stun, kill.
Stun and kill are 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
( ) will flash and option signalling will be released. The
transpond or alert tone will sound.
If the selective call alert LED is set up, the orange LED
will flash.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute ID/QT/DQT/Carrier.

In channels not set with QT/DQT, signalling is a match
just by rceiving the carrier.
■ Auto Reset
If option signalling matches a group set up with option
signalling, option signalling is released. After matching option signalling, option signalling will temporarily reset automatically.
■ Stun/Kill
If the stun code matches, a predetermined action will
occur. Whether option signalling is activated or not, when
stun code matches on any channel, the transceiver will become stun or kill.
While stun is active ("LOCK2" appears), if the stun code +
"#" code is received, stun will disactive. While kill is active
("ERROR" appears), the transceiver will be disable all functions. The transceiver must be reprogrammed by the FPU
(KPG-60D) to operation again.

If data is transferred to the transceiver from an IBM PC
with the KPG-60D, the destination data (basic radio information) for each set can be modified. Normally, it is not necessary to modify the destination data because their values are
determined automatically when the frequency range (frequency type) is set.
The values should be modified only if necessary.
Data can be programmed into the flash memory in RS232C format via the modular microphone jack.
KPG-60D instruction manual parts No. : B62-1315-XX.
6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the TK-880. This allows the
TK-880 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-880 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 (Fpro. exe).
2. Set the communications speed (normally, 57600 bps)
and communications port in the configuration item.
3. Set the firmware to be updated by File name item.
4. Turn the TK-880 Power ON with the [A] switch held
down. Hold the switch down until the display changes to
"PROG 57600". When "PROG 57600" appears, release
your finger from the switch.
5. Check the connection between the TK-880 and the personal computer, and make sure that the TK-880 is in the
Program mode.
6. Press write button in the window. A window opens on
the display to indicate progress of writing. When the TK880 starts to receive data, the [P] icon is blinking.
7. If writing ends successfully, the LED on the TK-880 lights
and the checksum is displayed.
8. If you want to continue programming other TK-880, repeat steps 4 to 7.
Notes :
• This mode cannot be entered if the Firmware programming mode is set to Disable in the Programming software (KPG-60D).
• 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.
2. If you press the [D] switch while "PROG 57600" is displayed, the display changes to "PROG 19200" to indicate
that the write speed is low speed (19200 bps). If you
press the [D] switch again while "PROG 19200" is displayed, the display changes to "PROG 38400", and the
write speed becomes the middle speed (38400 bps). If
you press the [D] switch again while "PROG 38400" is displayed, the display returns to "PROG 57600".
3. If you press the [D] switch while the version is displayed,
the checksum is displayed. If you press the [D] switch
again while the checksum is displayed, the version is
redisplayed.
Note :
Normally, write in the high-speed mode.
7. Self Programming Mode
Write mode for frequency data and signalling etc. Mainly
used by the person maintaining the user equipment.
7-1. Enter to the Self Programming Mode
Delete R614 (SELF, Figure 2) in the TX-RX unit and turn
the power switch on while pressing the [CALL] key. When
enter the self programming mode, "SELF PROG" is displayed.
Note :
This mode (self programming mode) cannot be set when
it has been disabled with the KPG-60D.

CIRCUIT DESCRIPTION
first IF signal of 44.85MHz. The first local signal passes
through an LPF and an attenuator to eliminate unwanted
harmonics components and implement the optimum input
level to the mixer, then enters IC200. A DBM is used as a
mixer to achieve a high potential.
The signal output from the mixer is amplified by an intermediate frequency amplifier and input to two MCFs (XF1).
The signal is amplified by another intermediate amplifier and
goes to the FM IF IC (IC11). The first intermediate frequency signal is mixed with the second local signal of
44.395MHz to produce the second IF signal of 455kHz.
The unwanted near-by signal components are then eliminated by a wide ceramic filter (CF1) or a narrow ceramic filter (CF2) and the resulting signal goes back to the FM IF IC.
The signal is quadrature-detected in the IC to produce an
audio signal, which is amplified by a DET amplifier (IC2) and
output to the control unit.
Frequency Configuration
The TX-RX unit incorporates a VCO, based on a fractional
N type PLL synthesizer system, that allows a channel step
of 5, 6, and 25kHz to be selected. The incoming signal from
the antenna is mixed with a first local oscillation frequency
to produce a first intermediate frequency of 44.85MHz.
The signal is then mixed with a second local oscillation
frequency of 44.395MHz to produce a second intermediate
frequency of 455kHz. This is called a double-conversion
system. The TX-RX unit contains a wide/narrow MCF and
CFs. The transmit signal is produced by the PLL circuit for
direction oscillation and division. The signal output from the
VCO is amplified by a straight amplifier and transmitted.

■ Outline
The incoming signal from the antenna passes through a
low-pass filter and a transmission/reception selection diode
switch (D209) and goes to the front end of the receiver. The
front-end filter is a variable BPF consisting of two two-pole
helical resonators and eight varicap diodes (D203, D204,
D205, D206, D212, D213, D214, D215) to eliminate unwanted out-of-band signal components. The low-noise amplifier (LNA) (Q201) uses a bipolar transistor to achieve wideband and low-distortion amplification.
The signal passes through a BPF and is down-converted
with the first local signal by IC200, then converted to the
5C

CIRCUIT DESCRIPTION
■ AF Signal System
The detection signal (DEO) from the TX-RX unit goes to
the audio processor (IC504) of the control unit. The signal
passes through a filter in the audio processor to adjust the
gain, and is output to IC502. IC502 sums the AF signal and
the DTMF signal and returns the resulting signal to the TXRX unit. The signal (AFO) sent to the TX-RX unit is input to
the D/A converter (IC5). The AFO output level is adjusted by
the D/A converter. The signal output from the D/A converter
is added with the BEEP signal (BPO) and the resulting signal
is input to the audio power amplifier (IC10). The AF signal
from IC10 switches between the internal speaker and
speaker jack (J1) output.

■ Squelch Circuit
The detection output from the FM IF IC (IC11) is amplified by IC2 and the signal (DEO) is sent to the control unit.
The signal passes through a high-pass filter and a noise amplifier (Q503) in the control unit to detect noise. A voltage is
applied to the CPU (IC511). The CPU controls squelch according to the voltage (ASQ) level. The signal from the RSSI
pin of IC11 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.

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.
■ VCO/PLL Circuit
The TK-880 has a VCO for the transmitter and a VCO for
the receiver in a sub-unit (A-1). They are housed in a solid
shielded case and connected to the TX-RX unit through
CN101. One of the VCOs is selected with an ST signal. A
filtered low-noise power supply is used for the VCOs and
varicap diodes.
The VCO for the transmitter is described below. It is designed so that Q103 turns on with a prescribed frequency
when a reverse bias is applied to D102 and D104 by using
the control voltage (CV) through CN101. The control voltage
is changed by turning the trimmer capacitor (IC109). The
output from Q103 is applied to the buffer amplifier (Q106) to
generate a VCO output signal. This signal is used as a drive
input signal or a local signal of the first mixer. Since a signal
output from Q160 is input to the PLL IC, it passes through
CN101 and buffer amplifier (Q300) and goes to the PLL IC
(IC300). The modulation signal from CN101 is applied to
D105 and passes through C112 and C113 to modulate the
carrier.
The PLL IC uses a fractional N type synthesizer to improve the C/N ratio and lock-up speed. The VCO output signal input to the pin 5 of the PLL IC is divided to produce a
comparison frequency according to a channel step. This signal is compared with the reference frequency which is output from the VCXO (X1). VCXO provides 16.8MHz, 2.5ppm
(–30 to +60°C) and guarantees stable performance when
the temperature changes. The output signal from the phase
comparator passes through a charge pump and an external
active LPF (Q301, Q302) in the PLL IC to generate a DC VCO
control voltage CV. Serial data (DT, CK, EP) are output from
the CPU (IC511) and shift register (IC8) in the control unit to
control the PLL IC. The PLL lock status is always monitored
by the CPU.

CIRCUIT DESCRIPTION
■ Unlock Circuit
During reception, the TR signal goes high, the KEY signal
goes low, and Q10 turns on. Q11 turns on and a voltage is
applied to the collector (8R). During transmission, the TR
signal goes low, the KEY signal goes high and Q13 turns on.
Q12 turns on and a voltage is applied to 8T.
The CPU in the control unit monitors the PLL (IC300) LD
signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this
signal and makes the KEY signal low. When the KEY signal
goes low, no voltage is applied to 8T, and no signal is transmitted.

Q17 turns the PC signal on or off using 8T so that the
circuit works only during transmission. With stability at low
power in mind, Q29 turns off to optimize the detection voltage.
The APC circuit is configured to protect overcurrent of
the power module due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage
and temperature variations.
Control Circuit
The CPU carries out the following tasks:
1) Controls the shift register (IC7, IC8, IC508) AF MUTE,
WIDE/NARROW, T/R KEY outputs.
2) Adjusts the AF signal level of the audio processor (IC504)
and turns the filter select compounder on or off.
3) Controls the DTMF decoder (IC507).
4) Controls the LCD assembly display data.
5) Controls the PLL (IC300).
6) Controls the D/A converter (IC5) and adjusts the volume,
modulation and transmission power.

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.

CIRCUIT DESCRIPTION
■ Display Circuit
The CPU (IC511) controls the shift register (IC508) and
display LEDs. When the LG line goes high when the transceiver is busy, Q508 turns on and the green LED on D511
lights. In transmit mode, the LR line goes high, Q509 turns
on and the red light lights. Backlighting LEDs for the key
operation unit (D512~D517) and LCD are provided.
When the KBLC line goes high, Q512 turns on, then
Q513 turns on, and the key illumination LED lights. A voltage is applied to the LEDA line to turn on the LCD backlight.
MO is summed with the external pin DI line by the summing amplifier (IC3) and the resulting signal goes to the D/A
converter (IC5). The D/A converter (IC5) adjusts the MO
level and the balance between the MO and TO levels. Part
of a TO signal is summed with an output signal from pin 3
(MO) of IC5 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.

■ Key Matrix Circuit
The TK-880 front panel has ten keys. Each of them is
connected to a cross point of a matrix of the KEY1 to KEY7
ports of the microprocessor. The KEY5 to KEY7 ports are
always high, while the KEY1 to KEY4 ports are always low.
The microprocessor monitors the status of the KEY1 to
KEY7 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. Unused
points (KEY1 to KEY7) are also used for foot switch (FSW)
input.
The signal (DEO) detected by the TX-RX unit passes
through two low-pass filters of IC501, goes to LSDI of the
CPU (IC511) to decode QT, DQT. The DTMF signal is decoded by a dedicated IC (IC507) and the resulting signal is
sent to the CPU (IC511) as serial data (STD).
The 5-tone signal passes through high-pass filter, IC504
and then through low-pass filter, IC710. After passing
through these filters, only the audio signal between 300Hz
and 3kHz is extracted and input to comparator, IC502. The
comparator converts the input signal into a square waveform (0 and 5V). This square waveform is then fed to the
HSDI line of CPU (IC511).

■ D/A Converter
The QT, DQT signals are output from LSDO of the CPU
(IC511) and go to the D/A converter (IC5) of the TX-RX unit.
The DTMF and single/5-tone signals are output from HSDO
of the CPU and goes to the audio processor (IC504). An
MSK signal is output from the audio processor according to
the data (AFDAT) from the CPU. The signal is summed with
a MIC/MSK signal by the audio processor (IC504), and the
resulting signal passes through an analog switch (IC506) and
goes to the TX-RX unit (MO).
The D/A converter (IC5) is used to adjust TONE and MO
modulation, beep, 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)

CIRCUIT DESCRIPTION
■ Horn Control
The horn switch, consisting of Q4, Q5, and Q6, controls
the horn relay. It is supplied by the dealer to provide the
external horn alert function.
Q5 disables horn alert, turning on when its base is high,
to inhibit the function. Normally, the output from IC7 is low,
and Q6 is off; the base of Q4 is about 0V and Q4 is off.
When horn alert is enabled, the output from IC7 goes high
and Q6 turns on. The base current flows through R58 to Q4
to turn Q4 on. Q4 can sink a maximum of 100mA. If the
operational 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 (IC15). This IC outputs a control signal
when the PSW goes low. When the power turns on, pin 1 of
IC15 outputs a low signal and Q30 turns on. The base of
Q28 goes high, Q28 turns on, SB SW (Q27) turns on and
power (SB) is supplied to the set.
This circuit has an over-voltage protection circuit. If a DC
voltage of 20 V or higher is applied to the power cable, D34
turns on and a voltage is applied to the base of Q31. This
voltage turns Q31 on and turns Q28 and SBSW off. This
circuit has a TIMED POWER OFF (TOF) function which can
be programmed by software.
It is controlled through pin 6 of IC7. When the TOF line
goes high, Q22 turns on and then Q25 turns on. Pin 6 of
IC15 goes high, then pin 1 goes high to turn Q27 off.

■ 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)
Channel appears on LCD. Set channel according to tuning requirements.

The firmware program (User mode, Test mode, Tuning
mode, etc.) and the data programmed by the FPU (KPG-60D)
for the flash memory, is stored in memory. When parts are
changed, program the data again.
■ Repair Jig (Chassis)
• EEPROM
The tuning data (Deviation, Squelch, etc.) for the
EEPROM, is stored in memory. When parts are changed,
readjust the transceiver.
Use jig (Part No. : A10-4010-02) for repairing the TK-880.
The jig facilitates the voltage check when the voltage on the
component side TX-RX unit is checked during repairs.
