the signal is filtered through a band pass filter (L203 and
L214) to eliminate unwanted signals before it is passed to
the fi rst mixer. Band pass fi lters (L208, L209, L210, L203
and L214) have varactor diodes (D203, D204, D205, D202
and D201).

The voltage of these diodes are controlled by to track the
MPU (IC403) center frequency of the band pass fi lter. (See

2) First Mixer

The signal from the RF amplifi er is heterodyned with the
fi rst local oscillator signal from the PLL frequency synthe­sizer circuit at the fi rst mixer (Q202) to create a 38.85MHz
fi rst intermediate frequency (1st IF) signal. The fi rst IF signal
is then fed through two monolithic crystal filters (MCFs :
XF200) to further remove spurious signals.

3) IF Amplifi er

The fi rst IF signal is amplifi ed by Q201, and then enters
IC200 (FM processing IC). The signal is heterodyned again
with a second local oscillator signal within IC200 to create
a 450kHz second IF signal. The second IF signal is then fed

6

through a 450kHz ceramic fi lter (CF200) to further eliminate
unwanted signals before it is amplifi ed and FM detected in
IC200.

4) AF Amplifi er

The recovered AF signal obtained from IC200 is amplifi ed
by IC300 (1/4), fi ltered by the IC300 low-pass fi lter (2/4) and
IC300 high-pass filter (3/4) and (4/4), and de-emphasized
by R303 and C306. The AF signal is then passed through a
WIDE/NARROW switch (Q303). The processed AF signal
passes through an AF volume control and is amplifi ed to a
suffi cient level to drive a loud speaker by an AF power am­plifi er (IC302).

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, IC403 sends a high
signal to the MUTE and AFCO Iines and turns IC302 on
through Q302, Q304, Q305, Q306 and Q307.(See Fig. 3)

3. PLL Frequency Synthesizer

The PLL circuit generates the fi rst 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 oscillator signal is divided at IC1 by
a fi xed counter to produce the 5 or 6.25kHz reference fre­quency. The voltage controlled oscillator (VCO) output signal
is buffer amplifi ed by Q6, then divided in IC1 by a dual-mod­ule 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 fi ltered through a low-pass fi lter and passed to the
VCO to control the oscillator frequency. (See Fig.4)

TK-2102G

CIRCUIT DESCRIPTION

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 (D1 and

3) Unlock Detector

If a pulse signal appears at the LD pin of IC1, an unlock
condition occurs, and the DC voltage obtained from D7, R1,
and C1 causes the voltage applied to the UL pin of the mi­croprocessor to go low. When the microprocessor detects
this condition, the transmitter is disabled, ignoring the push­to-talk switch input signal. (See Fig.5)

D2 in transmit mode and D3 and D4 in receive mode). The
T/R pin is set high in receive mode causing Q5 and Q7 to
turn Q4 off, and turn Q3 on . The T/R pin is set low in trans­mit mode. The outputs from Q3 and Q4 are amplifi ed by Q6
and sent to the buffer amplifi ers.

1) Transmit Audio

The modulation signal from the microphone is amplifi ed
by IC500 (1/2), passes through a pre-emphasis circuit, and
amplifi ed by the other IC500 (1/2) to perform IDC operation.
The signal then passes through a low-pass filter (splatter
fi Iter) (Q501 and Q502) and cuts 3kHz and higher frequen­cies. The resulting signal goes to the VCO through the VCO
modulation terminal for direct FM modulation. (See Fig. 6)

2) QT/DQT Encoder

A necessary signal for QT/DQT encoding is generated by
IC403 and FM-modulated to the PLL reference signal. Since
the reference OSC does not modulate the loop characteris­tic frequency or higher, modulation is performed at the VCO
side by adjusting the balance. (See Fig. 6)

3) VCO and RF Amplifi er

The transmit signal obtained from the VCO buffer am­plifi er Q100, is amplifi ed by Q101. This amplifi ed signal is
passed to the power amplifi er, Q102 and Q105, which con­sists of a 2-stage FET amplifi er and is capable of producing
up to 5W of RF power. (See Fig.7)

5) APC

The automatic power control (APC) circuit stabilizes the
transmitter output power at a predetermined level by sens­ing the drain current of the fi nal amplifi er Field Effect Tran­sistor (FET) . The voltage comparator, IC100 (2/2), compares
the voltage obtained from the above drain current with a
reference voltage which is set using the microprocessor.
An APC voltage proportional to the difference between the
sensed voltage and the reference voltage appears at the
output of IC100 (1/2). This output voltage controls the gate
of the FET power amplifier, which keeps the transmitter
output power constant. The transmitter output power can
be varied by the microprocessor which in turn changes the
reference voltage and hence, the output power.

6) Thermal Protection Circuit

When the thermistor (TH100) reaches about 80˚C, the
protection circuit turns on Q107 to protect transmitting fi nal
amplifi er (Q105) from the over heating.

5. Power Supply

A 5V reference power supply [5M] for the control circuit
is derived from an internal battery. This reference is used
to provide a 5V supply in transmit mode [5T], a 5V supply in
receive mode [5R], and a 5V supply common in both modes
[5C] based on the control signal sent from the microproces­sor.

6. Control System

The IC403 MPU operates at 7.37MHz . This oscillator has
a circuit that shifts the frequency according to the EEPROM
data.

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 con-

nected 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.
