INTRODUCTION
PERSONNEL SAFETY
SCOPE OF THIS MANUAL
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 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 technicians.
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.

TK-890/(B)/H(B)
GENERAL
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. QT 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. 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.
SERVICE
This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and alignment procedures contained in this manual.

(4) If the RADIO receives a proper signal while scanning,
scanning stops temporarily, audio is unmuted, and the
channel number or name is displayed.
If either “Priority1” or “Priority2” is programmed and
scanning stops at a Normal Channel by receiving a signal,
the RADIO watches for a signal on the Priority Channel
periodically. When a signal exists on the Priority Channel,
the channel will change from the Normal Channel to Priority Channel.
If both “Priority1” and “Priority2” are programmed and
scanning stops at the Priority2 Channel by receiving a signal, the RADIO watches a signal on the Priority1 Channel
periodically. When a signal exists on the Priority1 Channel, the channel will change from the Priority2 Channel to
the Priority1 Channel.
If there is no Priority Channel programmed, the scanning
stops at a channel and receives only that channel.
(5) If the [SCN] Key pressed again, Scan Mode ends at the
revert channel, and two confirmation tones sound.
4-2. To Delete Undesired Channels
To temporarily delete undesirable channels, press [D/A]
Key while the channel is displayed, and scanning resumes.
(To temporarily delete Priority Channel 1 or 2, set the “Priority Temporary D/A” function to “YES”.)
You can’t delete a channel in Scan Mode under the following conditions:
• Priority Scan
There is only channel beside the Priority Channel in the
scan sequence.
• Non-priority Scan
There are only 2 channels in the scan sequence. To restore the original scan sequence, either turn scan off and
on or turn the RADIO off and on.

• Pin 13
MI/DI (MIC Signal Input/Output or Data Audio Input)
This pin has one of the two functions listed in Table 3 by
setting jumper resistors (0 ohm) R640 and R641 on the
control unit (X57-562 B/3) (Refer to page 21).
1) MIC signal input/output
This pin is directly connected to the MIC input pin of the
transceiver, so it has the same function as the MIC input
pin. When the input is 5mV/3 kHz, DEV (600 ohms)
modulation is obtained. The MIC input is output from the
transceiver panel as it is.
2) Data audio input
The signal from this pin passes through the LPF (fc: about
10kHz), is summed with the MIC AMP output, and goes
to the modulator. Therefore, it is not preemphasized.
• Pin 14
SB (DC Power Output After Power Switch)
The maximum output (13.6V : TK-890/(B), 13.4V : TK890H(B) / 0.5A) can be obtained by modifying the control
unit as follows:

The signal from the DO terminal of the CN1 is applied to
drive the power module and the output is fed through transmit/receive switching diode ; D3~D5, low-pass filter, and
CM coupler to the antenna connector.
CM coupler is a line for detecting traveling and reflected
waves. Traveling waves are detected by D6 and fed through
the APC control to differential amplifiers Q5, which compare
the signal level with the reference voltage of PC tuned.
The output is amplified by DC amplifier Q1 to control APC
DC amplifier Q2. Q1 controls the power supply voltage for
the power module, keeping the transmitter output constant.
To protect the transmitter power amplifier stages, there is
protection circuit, against abnormal antenna loading.
If an abnormal antenna load is connected the reflected
wave level increases. Reflected waves are detected by D7
and the output level is fed to the differential amplifier, leading to the transmitter output power being reduced in the
way already described.

The signal from the DO terminal of the CN1 is applied to

signals which are amplified by Q6 and Q7. The signals are
mixed and the resulting signal is fed through CM coupler,
transmit/receive switching relay ; K1, and the low-pass filter
to the antenna connector.
CM coupler is a line for detecting traveling and reflected
waves. Traveling waves are detected by D1, D3 and fed
through the APC control to differential amplifiers Q5, which
compare the signal level with the reference voltage of PC
tuned.
The output is amplified by DC amplifier Q4 to control APC
DC amplifier Q3. Q4 controls the power supply voltage for
the power module, keeping the transmitter output constant.
To protect the transmitter power amplifier stages, there are
two protection circuits which one is against abnormal antenna loading and the other is against overheating.
If an abnormal antenna load is connected, the reflected
wave level increases. Reflected waves are detected by D2,
D3 and the output level is fed to the differential amplifier Q5,
leading to the transmitter output power being reduced in the
way already described. If an abnormal high temperature is
detected by the thermistor TH1, DC SW Q1 is made to reduce the reference voltage of the PC tuned. This also leads
to the transmitter output power being reduced. Antenna
switching is done by a relay K1 with 8R.

CIRCUIT DESCRIPTION
2. Receiver Circuit
Item
Incoming signals from the antenna pass through a lowpass filter in the final unit of the transmitter system, and are
switched to the front-end of the receiver system via a receive/transmit switch (switching diode D3, D4 and D5 : TK890/(B), switching relay K1 : TK-890H(B)).
The signal is then passed through an antenna matching
coil. After passing through the 2-pole BPF (L101), the signal
is amplified by the RF amplifier (Q101). The 3-pole BPF
(L104) is then passed, and it enters the 1st mixer.
The 1st mixer use a double balanced mixer (A101). The
DBM is an excellent IM (intermodulation distortion) and image. The 1st mixer mixes the signal with the 1st local oscillator frequency and converts it to the 1st IF (73.05MHz).
The signal is amplified by the 1st IF amplifier 1 (Q102).
The signal then passes through two monolithic crystal filters (XF101 : Wide, XF102 : Narrow) to remove unnecessary
nearby frequency components. The signal from the XF101
or XF102 is used as the 1st IF signal.
The 1st IF signal is amplified by 1st IF amplifier 2 (Q107)
and fed into IC101 in the FM IF IC. The IF signal is then
mixed with the 2nd local oscillator frequency of 73.505MHz
to generate the 2nd IF of 455kHz. The 455kHz signal is then
passed through a ceramic filter (CF101, CF103 : Wide,
CF102, CF104 : Narrow) and fed back into IC101 for additional amplification.
The AF signal output from IC101 then passes through
the control unit's HPF and D/A converter IC. After entering
the AF power amplifier (IC522), the signal is output from the
speaker.

TK-890/(B)/H(B)
CIRCUIT DESCRIPTION
The VCO of TK-890 consists of three VCO circuits which
one oscillates the transmit signal with Q305 and the others
do the first local receive signal with two RX-VCO. RX band
range is divided into two range which lower band oscillates
the RXL-VCO with Q306 and higher band does the RXH-VCO
with Q307.
Each oscillators are switched by turning the source line
for Q308, Q309, Q310, Q311 and Q312 on and off. The
signal output of the VCO is amplified by the buffer amplifier
Q313 and divided into two signals which one is amplified by
Q314 and the other is done by Q315. The signal from Q314
passes through D308 which is transmit/receive switch, is
amplified by Q201, Q204 and Q205, and is output from the
CN203.
The signal from Q315 passes through the low-pass filter
and is applied to IC301 which is PLL frequency synthesizer
with VCXO ; X301. The VCXO of which the frequency stability is within 2.0ppm (temperature range of –30 to +60°C)
generates 16.8MHz. The PLL-IC consists of three modulus
prescaler, fractional divider, reference divider, digital phase
comparator with charge pump output.
This PLL-IC is Fractional-N type synthesizer and performs
is 40 or 50kHz reference signal which is eighth of the channel step (5 or 6.25kHz). The input signal from the pins 5 and
8 of the PLL-IC is divided down to the 40 or 50kHz and compared at digital phase comparator.
The pulsed output signal of the digital phase comparator
is applied to the charge pump and transformed into DC signal. The DC signal from the pin 14 of the PLL-IC passes
through the active low-pass filter (loop filter), is applied to
the VCO and controls to keep the frequency of the VCO.
The serial data (DT, CP, EP) from the microprocessor
IC516 is input to the PLL-IC. And PLL lock condition is always monitored by the pin 28 (UL) of IC516.

5. VCO/PLL Circuit
The output from IC101 enters FM IC again, then passed
through a band-pass filter. The noise component output
from IC101 is amplified by Q109 and rectified by D103 to
produce a DC voltage corresponding to the nose level.
The DC voltage is sent to the analog port of the CPU
(IC516/pin 27). And IC101 output a DC voltage (RSSI) corresponding to the input of the IF amplifier. The CPU reads the
RSSI signal via pin 26. IC101 determines whether to output
sounds from the speaker by comparing the input voltage of
pin 27 with the present value.
Only during scan, the RSSI DC voltage is used together
with the noise wave detection pin's DC voltage (pin 27).

7. Signalling Circuit
6-1. Memory circuit
A flash memory (IC519) with a capacity of 2Mbits contains the transceiver control program for the CPU (IC516)
and data such as transceiver channels and operating features.
This program can be easily written from an external devices. Data, such as DTMF memories and operating status,
tuning data are programmed into the EEPROM (IC514).
6-2. Shift register
IC517 and IC523 are an interface IC for I/O port expansion. It is used to expand the CPU (IC516) output ports.
6-3. D/A converter
IC512 is used as a conventional semi-fixed-resistor converter. It sets the following :
1) RX sensitivity
2) Transmission power
3) Modulation level
4) Audio power
5) Frequency
6-4. Power supply circuit
D507 is a protection diode for the excess voltage
1) Turning the transceiver on/off with a power switch. Each
time you press the power switch, the IC501 output is alternated. The output is feed through Q501, Q503 to turn
Q519 on. The power source is always supplied to the
IGN terminal. If 24V DC is supplied to the transceiver by
mistake, Q502 is turned on then Q503 and Q519 are
turned off to protect the transceiver (turned off).
2) Turning the transceiver on with a power switch, then
turning the transceiver off with the Timed Power Off
(TPO) function. POF is controlled by CPU’s TPO function.
POF is to turn the transceiver off. The POF logic signal is
feed through Q507 and Q506 then 8 pin of IC501 to turn
the transceiver off.
3) Turning the transceiver on with IGN SENS, then turning
the transceiver off with TPO function. If IGN is turned on,
Q543 and Q542 are turned on then the IC501 detects the
change. IC501 outputs the signal to turn Q541 off, then
Q503 and Q519 are turned on. When POF is detected by
6 pin of IC501, Q541 is turned on then Q503 and Q519
are turned off.
7-1. Encode
• QT, DQT
The CPU (IC516) transmits the encode data selected by
the program. The data items are output from CPU pin 34.
The signal from this pin passes though the CR low-pass
filter and goes to the summing amplifier (IC510) in the microphone amplifier.
• DTMF
The DTMF-encoder (IC511) transmits the encode data.
The encode data is passed to the D/A convertor (IC512) for
DTMF deviation adjustment, and goes to IC505 in the IDC
circuit of the microphone amplifier.
7-2. Decode
• QT, DQT
The demodulated signal from CN502 pin 5 is amplified by
IC521 and passes through a low-pass filter (IC502) to remove audio components. The signal is input to pin 25 of the
CPU. The CPU digitizes this signal, and decodes the signal.
• 2 TONE
The demodulated signal from CN502 pin 5 is amplified by
IC504 and passes through a high-pass filter (IC518) and a
band-elimination filter (IC524) to remove QT and DQT.
This signal is amplified by IC521 and inputs pin 91 of the
CPU.
• DTMF
The demodulated signal from CN502 pin 5 is amplified by
IC504 and passes through a high-pass filter (IC518) and
band-elimination filter (IC524) to remove QT and DQT.
This signal inputs pin 1 of the DTMF decoder (IC525).

Panel Tune Mode
The transceiver is adjusted in this mode.
• To enter the panel tune mode
Press the [GR ] key in the panel test mode.
In this mode, QT and DQT signalling is decoded, but
2tone and DTMF signalling is not decoded.
The adjustment items, the frequency and signalling,
other than the maximum deviation and sensitivity, return to
the values that were effective for the test frequency channel and test signalling channel before entering the panel
tune mode.
The RF High Power adjustment item of only the TK-890H
K type can be adjusted by switching the frequency between
460MHz and 475MHz.
>
Panel Test Mode
The transceiver’s transmission output, receive sensitivity, and other items are measured and QT, DQT, 2tone and
DTMF signaling is decoded in this mode.
• To enter the panel test mode
Hold down [PF1] and turn the power switch on to enter
this mode. The test frequency channel and test signalling
channel will be displayed.
