3-1. Preface
The TK-3202/3206 transceivers are programmed using a
personal computer, a programming interface (KPG-22) and
programming software (KPG-87D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.

3-2. Connection procedure
1. Connect the TK-3202/3206 to the personal computer with
the interface cable.
2. When the POWER is switched on, user mode can be
entered immediately. When the PC sends a command,
the radio enters PC mode.
When data is transmitting from the transceiver, the red
LED lights.
When data is received by the transceiver, the green LED
lights.
Notes:
• The data stored in the personal computer must match the
model type when it is written into the EEPROM.
• Change the TK-3202/3206 to PC mode, then attach the
interface cable.

4. Clone Mode
4-1. Outline
"Clone Mode" copies the transceiver data to another
transceiver.
The dealer can copy the transceiver data to another
transceiver even without the use of a personal computer.

4-2. Example
The transceiver can copy the programming data to one or
more transceivers via RF communication.
The clone master and clone slave/s must be in Clone mode.

4-3. Operation
1. To switch the clone slave/s to Clone mode, press and hold
the [PTT] and [side2] keys while turning the transceiver
power ON.
2. Wait for 2 seconds. The LED will light orange and the
transceiver will announce "Clone".
3. Select a channel table number using Side1(increment
channel table) and Side2(decrement channnel table) keys.

4. To switch the clone master to Clone mode, press and hold
the [PTT] and [side2] keys while turning the transceiver
power ON.
5. Wait for 2 seconds. The LED will light orange and the
transceiver will announce "Clone".
6. Select the same channel table number as the clone slave/s.
7. Press [PTT] on the clone master to begin data transmission.
When the clone slave starts to receive data, the LED will
light green.
When the clone master finishes sending data, a
"confirmation" tone will sound.
If data transmission fails while cloning, an "error" tone will
sound from the Slave unit.
8. If the cloning fails, no data will be available in the Slave unit
when it is returned to User mode.
9. When the cloning is successful, the Slave unit's "Scan" and
"Key lock" functions will return to their default values (Scan
= OFF, Key lock = OFF).
Notes:
• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceivers Clone Mode is configured as "Disabled",
the transceiver cannot enter Clone mode.
• The table shown below will cover the frequency tables used
for wireless cloning.
• Clone mode cannot be entered in battery low state.
• A unit cannot be a "Master Unit" if it is unprogrammed. If
[PTT] is pressed, an "error" tone will sound.
• The language used in cloning depends on the "Model type"
setting, not the FPU setting. C, C2, C5 and C6 type
TK-3207 transceivers will use Chinese. Other types English.
• Once a unit is set to be the Master, it cannot be a slave
after the data has been transmitted. This protects the data
in the Master unit.
• Electronic interface may cause a failure in data transfer
during Wireless Clone, such as when waveforms or
electromagnetics are being performed at the workbench.
• Clone mode can be used ONLY by the authorized service
personnel.
• The Clone mode setting must be configured as "Disable"
before being delivered to the end-user.
• To clone, replace the antenna from both the master
transceiver and the slave transceiver with a dummy
load.
• The transmit output power is automatically set to Low
in Clone mode.

The first IF signal is passed through a four-pole monolithic
crystal filter (XF201) to remove the adjacent channel signal.
The filtered first IF signal is amplified by the first IF amplifier
(Q203) and then applied to the lF system IC (IC201). The IF
system IC provides a second mixer, second local oscillator,
limiting amplifier, quadrature detector and RSSI (Received
Signal Strength Indicator). The second mixer mixes the first
IF signal with the 38.4MHz of the second local oscillator
output (TCXO X1) and produces the second IF signal of
450kHz.
The second IF signal is passed through the ceramic filter
(CF201) to remove the adjacent channel signal. The filtered
second IF signal is amplified by the limiting amplifier and
demodulated by the quadrature detector with the ceramic
discriminator (CD201). The demodulated signal is routed to
the audio circuit.

1) Front End (RF AMP)
The signal coming from the antenna passes through the
transmit/receive switching diode circuit, (D103,D104,D106
and D122) passes through a BPF (L229 and L228), and is
amplified by the RF amplifier (Q205).
The resulting signal passes through a BPF (L214,L212 and
L211) and goes to the mixer. These BPFs are adjusted by
variable capacitors (D203,D204,D205,D206 and D210). The
input voltage to the variable capacitor is regulated by
voltage output from the microprocessor (IC405).

2) First Mixer
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q1 to
produce a first IF frequency of 38.85 MHz.
The resulting signal passes through the XF201 MCF to cut
the adjacent spurious and provide the opitimun
characteristics, such as adjacent frequency selectivity.

5) Audio Amplifier Circuit
The demodulated signal from IC201 goes to AF amplifier
through IC301.
The signal then goes through an AF volume control, and is
routed to an audio power amplifier (IC302) where it is amplified
and output to the speaker.

TK-3202/3206
CIRCUIT DESCRIPTION
6) Squelch
Part of the AF signal from the IC enters the FM IC (IC201)
again, and the noise component is amplified and rectified
by a filter and an amplifier to produce a DC voltage
corresponding to the noise level.
The DC signal from the FM IC goes to the analog port of
the microprocessor (IC405). IC405 determines whether to
output sounds from the speaker by checking whether the
input voltage is higher or lower than the preset value.
To output sounds from the speaker, IC405 sends a high
signal to the SP MUTE line and turns IC302 on through
Q303,Q304,Q305,Q306 and Q316. (See Fig. 4)

7) Receive Signalling
(1) QT/DQT
The output signal from FM IC (IC201) enters the
microprocessor (IC405) through IC301. IC405 determines
whether the QT or DQT matches the preset value, and
controls the SP MUTE and the speaker output sounds
according to the squelch results.

phase with the 5 or 6.25kHz reference signal from 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. 5)

2) VCO
The operating frequency is generated by Q4 in transmit
mode and Q3 in receive mode. The oscillator frequency is
controlled by applying the VCO control voltage, obtained
from the phase comparator, to the varactor diodes (D4 and
D7 in transmit mode and D5 and D9 in receive mode). The
RX pin is set high in receive mode causing Q5 turn on.
The TX pin is set high in transmit mode. The outputs from
Q3 and Q4 are amplified by Q6 and sent to the RF amplifiers.

(3) DTMF
The DTMF input signal from the FM IC (IC201) goes to
IC301, the DTMF decoder. The decoded information is then
processed by the CPU.

If a pulse signal appears at the LD pin of IC1, an unlock
condition occurs, and the DC voltage obtained from C4,
R5, and D1 causes the voltage applied to the microprocessor
to go low. When the microprocessor detects this condition,
the transmitter is disabled, ignoring the push-to-talk switch
input signal.

The PLL circuit generates the first local oscillator signal for
reception and the RF signal for transmission.

1) PLL
The frequency step of the PLL circuit is 5 or 6.25kHz.
A 12.8MHz reference an oscillator signal is divided at IC1
by a fixed counter to produce oscillator (VCO) output signal
which is buffer amplified by Q2 then divided in IC1 by a
programmable counter. The divided signal is compared in

CIRCUIT DESCRIPTION
4. Transmitter System
1) Microphone Amplifier
The signal from the microphone passes through IC301.
When encoding DTMF, it is turned OFF for muting the
microphone input signal by IC301.
The signal passes through the Audio processor (IC301) for
the maximum deviation adjustment, and goes to the VCO
modulation input.

2) Drive and Final Amplifier
The signal from the T/R switch (D101 is on) is amplified by
the pre-drive (Q101) and drive amplifier (Q102) to 50mW.
The output of the drive amplifier is amplified by the RF power
amplifier (Q103) to 4.0W (1W when the power is low). The
RF power amplifier consists of two MOS FET stages. The
output of the RF power amplifier is then passed through
the harmonic filter (LPF) and antenna switch (D103 and
D122) and applied to the antenna terminal.

3) APC Circuit
The APC circuit always monitors the current flowing through
the RF power amplifier (Q103) and keeps a constant current.
The voltage drop at R127, R128 and R129 is caused by the
current flowing through the RF power amplifier and this
voltage is applied to the differential amplifier IC101(1/2).
IC101(2/2) compares the output voltage of IC101(1/2) with
the reference voltage from IC405. The output of IC101(2/2)
controls the VG of the RF power amplifier, Drive amplifier

There are four 5V power supplies for the microprocessor:
5M,5C,5R, and 5T. 5M for microprocessor is always output
while the power is on. 5M is always output, but turns off when
the power is turned off to prevent malfunction of the
microprocessor.
5C is a common 5V and is output when SAVE is not set to
OFF.
5R is 5V for reception and output during reception.
5T is 5V for transmission and output during transmission.

(1) QT/DQT
QT,DQT data of the QTTCXO Line is output from pin 28 of
the CPU. The signal passes through a low-pass CR filter
and goes to the TCXO(X1).
The QT,DQT data of the QTVCO Line is output from pin 24
of the CPU. The signal passes through a low pass CR filter,
mixes with the audio signal, and goes to the VCO modulation
input. TX deviation is adjusted by the CPU.

(3) MSK (Fleet Sync)
Fleet Sync utilizes 1200bps and 2400bps MSK signal is
output from pin 6 of IC301. And is routed to the VCO.
When encoding MSK, the microphone input signal is muted.

(2) DTMF
High-speed data is output from pin 2 of the CPU. The signal
passes through a low-pass CR filter, and provides a TX and
SP out tone, and is then applied to the audio processor
(IC301). The signal is mixed with the audio signal and goes
to the VCO.
TX deviation is adjusted by the CPU.

and Pre-Drive amplifier to make both voltages the same.
The change of power high/low is carried out by the change
of the reference voltage.

The control circuit consists of a microprocessor (IC405) and
its peripheral circuits. It controls the TX-RX unit. IC405 mainly
performs the following:
(1) Switching between transmission and reception by the
PTT signal input.
(2) Reading system, group, frequency, and program data
from the memory circuit.
(3) Sending frequency program data to the PLL.
(4) Controlling squelch on/off by the DC voltage from the
squelch circuit.
(5) Controlling the audio mute circuit by the decode data
input.
(6) Transmitting tone and encode data.

1) Frequency Shift Circuit
The microprocessor (IC405) operates at a clock of
7.3728MHz. This oscillator has a circuit that shifts the
frequency by BEAT SHIFT SW (Q407, Q408).

TK-3202/3206
CIRCUIT DESCRIPTION
A beat sound may be able to be evaded from generation if
“Beat Shift” is set to ON when it is generated in the internal
spurious transmission modulated sound of a transceiver.

(1) The red LED blinks when the battery voltage falls below
the voltage (1) shown in the table during transmission.
Note:
The transceiver checks the battery voltage during reception
even when, in the FPU, the Battery Warning status function
is set to “On TX” (default setting).
However, the LED does not blink during reception. During
transmission, the LED blinks to generate the warning tone
of a low battery voltage.
(2) The transceiver immediately stops transmission when
the battery voltage falls below the voltage (2) shown in
the table. A message tone beeps while the PTT switch
is released.

■ The following parts are required for
adjustment
1. Antenna connector adapter
The antenna connector of this radio uses an SMA terminal.
Use an antenna connector adapter [SMA(f) – BNC(f) or
SMA(f) – N(f)] for adjustment. (The adapter is not provided as
an option, so buy a commercially-available one.)

2. Repair Jig (Chassis)
Use jig (part No.: A10-4086-03) for repairing the TK-3202/
3206. Place the TX-RX unit on the jig and fit it with screws.

Connect the power cable properly between the battery jig
installed in the transceiver and the power supply, and be sure
output voltage and the power supply polarity prior to switching
the power supply ON, otherwise over voltage and reverse
connection may damage the transceiver, or the power supply
or both.
Note: When using the battery jig, you must measure the
voltage at the terminals of the battery jig. Otherwise, a slight
voltage drop may occur within the power cable, between the
power supply and the battery jig, especially while the
transceiver transmits.

The jig facilitates the voltage check and protects the final
amplifier FET when the voltage on the flow side of the TX-RX
unit is checked during repairs.

• Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the unit
to a suitable power supply.
Whenever the transmitter is tuned, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
