3. PRE-INSTALLATION␣ CHECKOUT
3-1. Introduction
5. INSTALLATION␣ PLANNING – CONTROL␣ STATIONS
5-1. Antenna system
Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation.
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.
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.
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.
NOTE
If you do not intend to use the 3.5-mm jack for the external speaker, fit the supplied speaker-jack cap to stop dust
and sand getting in.
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.

OPERATING␣ FEATURES
■ Temporary delete
■ Clear to transpond
It is possible to delete channel temporary during scan.
When scan stops on unnecessary channel for example by
interference of the other party, activate the delete function
(for example press and hold the key for approximately one
second), then that channel is deleted temporarily and scan
re-start immediately.
The temporary deleted channels return to pre-set delete/
add channels, when the transceiver is turned off or the scan
function is switched off.
The transceiver waits the transpond of DTMF if channel
is busy until channel open. This feature prevents the interference to other party.
5. Details of Features
■ Time-out timer
The time-out timer can be programmed in 30 seconds
increments from 30 seconds to five minutes and off. If the
transmitter is transmitted continuously for longer than the
programmed time, the transmitter is disabled and a warning
tone sounds while the PTT button is held down. The warning tone stops when the PTT button is released.
■ PTT ID
PTT ID provides a DTMF ANI to be sent with every time
PTT (beginning of transmission, end of transmission, or
both).
You can program PTT ID "on" or "off" for each channel.
The contents of ID are programmed each Radio.
The timing that the transceiver sends ID is programmable.
BOT : DTMF ID (Beginning of TX) is sent on beginning of
transmission.
EOT : DTMF ID (End of TX) is sent on end of transmission.
Both : DTMF ID (Beginning of TX) is sent on beginning of
transmission and DTMF ID (End of TX) is sent on end of
transmission.
■ Off hook decode
If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no
effect for decoding QT/DQT and option signalling.
■ "TOT" pre-alert
The transceiver has "TOT" pre-alert timer. This parameter
selects the time at which the transceiver generates "TOT"
pre-alert tone before "TOT" is expired.
"TOT" will be expired when the selected time passes
from a TOT pre-alert tone.
■ "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.

6. Option Signalling (DTMF)
Built-in DTMF decoder is available for option signalling.
It is possible to use individual call, group call, Stun.
If the option signalling matches, a predetermined action
will occur.
If option signalling matches on a channel is set up with
option signalling, the channel LED will flash and option signalling will be released. The transpond or alert tone will
sound.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute QT/DQT/Carrier.
■ SP Unmute
You can select the type of SP Unmute system for each
channel. The selection is as follows.
Carrier, QT/DQT:

The KPG-70D programming disk is supplied in 3-1/2" disk
format. The software on this disk allows a user to program
TK-7102 radio via a programming interface cable (KPG-46).
3-5. Programming With IBM PC
If data is transferred to the transceiver from an IBM PC
with the KPG-70D, the destination data (basic radio information) for each set can be modified.
4. Clone Mode
Programming data can be transferred from one radio to
another by connecting them via their modular microphone
jacks. The operation is as follows (the transmit radio is the
master and the receive radio is the slave).
NOTE: Clone mode should enabled.
1. Turn the master TK-7102 power ON with the [1] key held
down. The TK-7102 [ ] LED is turned on.
2. Power on the slave TK-7102.
3. Connect the cloning cable (No. E30-3382-05) to the
modular microphone jacks on the master and slave.
4. Press the [ ] key on the master TK-7102 transceiver. The
data of the master is sent to the slave. While the master
is sending data, [TX] LED blinked. While the slave is receiving the data, 4 LEDs, [MON] LED, [ ] LED are turned
on and [BUSY] LED blinked. When cloning of data is completed, the master [TX] 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.

CIRCUIT DESCRIPTION
■ IF Amplifier
Frequency Configuration
The first IF signal is amplified by Q19, and the enters IC5
(FM processing IC). The signal is heterodyned again with a
second local oscillator signal within IC5 to create a 450kHz
second IF signal. The second IF signal is then fed through a
450kHz ceramic filter (Wide : CF1, Narrow : CF2) to further
eliminate unwanted signals before it is amplified and FM detected in IC5.
The receiver utilizes double conversion. The first IF is
49.95MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the necessary frequencies. Figure 1 shows the frequencies.

Frequency configuration
The receiver is double conversion superheterodyne. The
frequency configuration is shown in Figure 1.
■ Front-end RF Amplifier
An incoming signal from the antenna is applied to an RF
amplifier (Q26) after passing through a transmit/receive
switch circuit (D31 is off) and a band pass filter (L36, L38
and varactor diodes: D25, D26). After the signal is amplified
(Q26), the signal is filtered through a band pass filter (L30,
L32 and varactor diodes: D21, D22) to eliminate unwanted
signals before it is passed to the first mixer.
The voltage of these diodes are controlled by tracking the
CPU (IC6) center frequency of the band pass filter. (See Fig.
2)
Table 2
The signal from the RF amplifier is heterodyned with the
first local oscillator signal from the PLL frequency synthesizer circuit at the first mixer (Q21) to create a 49.95MHz
first intermediate frequency (1st IF) signal. The first IF signal
is then fed through two monolithic crystal filters (MCFs :
XF1) to further remove spurious signals.

CIRCUIT DESCRIPTION
■ Wide/Narrow Changeover Circuit
■ Squelch Circuit
The Wide port (pin 92) and Narrow port (pin 91) of the
CPU is used to switch between ceramic filters. When the
Wide port is high, the ceramic filter SW diodes (D13, D15)
cause CF1 to turn on to receive a Wide signal.
When the Narrow port is high, the ceramic filter SW diodes
(D13, D15) cause CF2 to turn on to receive a Narrow signal.
The detection output from the FM IF IC (IC5) passes
through a noise amplifier (Q18) to detect noise. A voltage is
applied to the CPU (IC6). The CPU controls squelch according to the voltage (SQIN) level. The signal from the RSSI pin
of IC5 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
Wide/Narrow changeover circuit
The PLL circuit generates the first local oscillator signal
for reception and the RF signal for transmission.
■ AF Signal System
The detection signal from IF IC (IC5) goes to AF amp (IC3)
to adjust the gain and is output to AF filter (IC10) for characterizing the signal. The AF signal output from IC10 and the
DTMF signal, BEEP signal are summed and the resulting signal goes to the D/A converter (IC3). The AFO output level is
adjusted by the D/A converter. The signal output from the
D/A converter is input to the audio power amplifier (IC16).
The AF signal from IC16 switches between the internal
speaker and speaker jack (J1) output.

■ PLL
The frequency step of the PLL circuit is 5 or 6.25kHz. A
16.8MHz reference oscillator signal is divided at IC1 by a
fixed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q15, then divided in IC1 by a dualmodule programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal in the
phase comparator in IC1. 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
The operating frequency is generated by Q11 in transmit
mode and Q10 in receive mode. The oscillator frequency is
controlled by applying the VCO control voltage, obtained
from the phase comparator, to the varactor diodes (D10 and
D12 in transmit mode and D9 and D11 in receive mode).
The TX/RX pin is set low in receive mode causing Q12 and
Q7 to turn Q11 off, and turn Q10 on. The TX/RX pin is set
high in transmit mode. The outputs from Q10 and Q11 are
amplified by Q15 and sent to the buffer amplifiers.

■ Unlock Circuit
Transmitter System
During reception, the 8RC signal goes high, the 8TC signal goes low, and Q29 turns on. Q31 turns on and a voltage
is applied to the collector (8R). During transmission, the
8RC signal goes low, the 8TC signal goes high and Q30
turns on. Q33 turns on and a voltage is applied to 8T.
The CPU in the control unit monitors the PLL (IC1) LD
signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this
signal and makes the 8TC signal low. When the 8TC signal
goes low, no voltage is applied to 8T, and no signal is transmitted.
■ 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 (D19) and amplified to a specified level of the power module (IC101) by the
drive block (Q23 and Q25). The amplified signal goes to a
low-pass filter. The low-pass filter removes unwanted highfrequency harmonic components, and the resulting signal is
goes the antenna terminal.

CIRCUIT DESCRIPTION
■ APC Circuit
The automatic transmission power control (APC) circuit
detects part of a power module output with a diode (D34,
D36) and applies a voltage to IC12. IC12 compares the APC
control voltage (PC) generated by the D/A converter (IC3)
and DC amplifier (IC4) with the detection output voltage to
control Q27 and Q28, generates DB voltage from B voltage,
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.
■ Display Circuit
The CPU (IC6) controls the display LEDs. When the transceiver is busy, the LEDG line goes high, Q4 turns on and the
green LED (D11) lights. In transmit mode, the LEDR line
goes high, Q8 turns on and the red LED (D12) lights. Backlit
LEDs (D1~D4) are provided.
When a function key (MON, PF, C1, C2, C3 or C4) is selected, its respective line goes high (LED MON, LED PF,
LED C1, LED C2, LED C3 or LED C4), the switch connected
to that line turns on and the amber LED lights.

Control Circuit
The CPU carries out the following tasks:
1) Controls the WIDE, NARROW, TX/RX outputs.
2) Adjusts the AF signal level of the AF filter (IC10) and turns
the filter select compounder on or off.
3) Controls the DTMF decoder (IC9).
4) Controls the display unit.
5) Controls the PLL (IC1).
6) Controls the D/A converter (IC3) and adjusts the volume,
modulation and transmission power.
The TK-7102 front panel has function keys. Each of them
is connected to a cross point of a matrix of the KMI1 to
KMO2 ports of the microprocessor. The KMO1 to KMO2
ports are always high, while the KMI1 to KMI4 ports are always low.
The microprocessor monitors the status of the KMI1 to
KMO2 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.

■ D/A Converter
The QT and DQT signals are output from QT/DQT of the
CPU (IC6) and summed with the external pin DI line by the
summing amplifier (IC4) and the resulting signal goes to the
D/A converter (IC3). The DTMF signal is output from DTMF
of the CPU and goes to the D/A converter (IC3). The signal
is summed with a MIC signal by the summing amplifier
(IC4), and the resulting signal goes to the D/A converter
(IC3).
The D/A converter (IC3) 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.
The D/A converter (IC3) is used to adjust MO modulation,
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 Circuit
When the POWER switch on the display unit is pressed,
the power port on the display unit which is connected to
CPU port 18 (POWER), goes low, then CPU port 93 (SBC)
goes high, Q34 turns on, SB SW (Q42) turns on and power
(SB) is supplied to the radio.
This circuit has an overvoltage protection circuit. If a DC
voltage of 18 V or higher is applied to the power cable, D39
turns on and a voltage is applied to the base of Q38. This
voltage turns Q38 on and turns Q34 and SB off.
