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.
•Aunit 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.
•Clonemodecanbe 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.

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.
Fig. 3 Wide/Narrow switching circuit
CIRCUIT DESCRIPTION
1. Frequency Configuration
The receiver utilizes double conversion. The first IF is 38.85
MHz and the second IF is 450 kHz. The first local oscillator
signal is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the necessary
frequencies. Fig. 1 shows the frequencies.
Fig. 1 Frequency configuration
1) Front End (RF AMP)
The signal coming from the antenna passes through the
transmit/receive switching diode circuit, (D103,D104,D105
and D106) passes through a BPF (L214 and L213), and is
amplified by the RF amplifier (Q205).
The resulting signal passes through a BPF (L209 and L211)
and goes to the mixer. These BPFs are adjusted by variable
capacitors (D203,D204,D205 and D206). 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.
Fig. 2 Receiver section
2. Receiver
The frequency configuration of the receiver is shown in Fig. 2.
3) IF Amplifier Circuit
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.
4) Wide/Narrow Switching Circuit
Narrow and Wide settings can be made for each channel
by switching the demodulation level.
The WIDE (low level) and NARROW (high level) data is
output from IC405, pin 45.
When a WIDE (low level) data is received, Q202 turn on.
WhenaNARROW (high level)data is received,Q202 turn off.
Q202 turns on/off with the Wide/Narrow data and the
IC201 detector output level is switched to maintain a
constant output level during wide or narrow signals.

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.
(2) MSK (Fleet Sync)
The MSK input signal from theFM IC goes to pin 31 of IC 301.
The signal is demodulated by MSK demodulator in IC 301.
The demodulated data goes to the CPU for processing.
3) Unlock Detector
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.
4. Transmitter System
1) Microphone Amplifier
The signal from the microphone passes through the 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.

CPU.
3. PLL Frequency Synthesizer
The PLL circuit generates the first local oscillator signal for
reception and the RF signal for transmission.
1) PLL
Thefrequencystep of the PLL circuit is 2.5,5,6.25or 7.5kHz.
A 12.8MHz reference oscillator signal is divided at IC1 by a
fixed counter to produce an oscillator (VCO) output signal
which is buffer amplified by Q2 then divided in IC1 by a
programmable counter. The divided signal is compared in
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.

CIRCUIT DESCRIPTION
Fig. 6 Microphone amplifier
Fig. 7 Drive and final amplifier and APC circuit
3) APC Circuit
The APC circuit always monitors the current flowing through
the RF power amplifier (Q106) 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
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.
4) Encode Signalling
(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).
2) Drive and Final Amplifier
The signal from the T/R switch (D101 is on) is amplified by
thepre-drive(Q102)andthe drive amplifier (Q103) to 50mW.
Theoutputof the drive amplifier is amplified by theRFpower
amplifier (Q106) to 5.0W (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
D104) and applied to the antenna terminal.

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,
mixeswiththe audio signal, and goes to theVCOmodulation
input. TX deviation is adjusted by the CPU.
(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.
(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.
5. Power Supply
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.
6. Control Circuit
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) Controllingthe audio mutecircuitby the decodedatainput.
(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).
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.

2) Memory Circuit
Memory circuit consists of the CPU (IC405) and an EEPROM
(IC406). An EEPROM has a capacity of 64k bits that contains
the transceiver control program for the CPU and data such
as transceiver channels and operating features.
3) Low Battery Warning
The battery voltage is checked using by the microprocessor.
Thetransceivergenerates a warning tone when itfallsbelow
the warning voltage shown in the table.
(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.
7. Control System
Keys and channel selector circuit.
The signal from the keys and channel selector are directly
input to the microprocessor, as shown in fig. 11.
