General
Manual Scope
This manual is intended for use by experienced technicians familiar with similar types of
communication equipment. It contains all service information required for the equipment and is current
as of the publication date.
User Safety Information
The following general safety precautions as would normally apply, should be observed during all phases
of operation, service and repair of this equipment.
◇This equipment should be serviced by qualified technicians only.
◇Do not operate the transmitter of radio unless all RF connectors are secure and any open
connectors are properly terminated.
◇Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into
contact with your skin, a minor burn can result.
◇Turn off your radio prior to entering any area with a potentially explosive atmosphere.
◇To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any
facility where posted notices instruct you to do so. Hospital or health facilities may be using
equipment that is sensitive to external RF energy.
◇When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be
in accordance with airline regulations or crew instructions.
◇To avoid possible interference with blasting operations, turn off your radio when you are near
electrical blasting caps, in a blasting area, or in areas posted: “Turn off two-way radio.”Obey all
signs and instructions.
◇For vehicles with an air bag, do not place a radio in the area over an air bag or in the air bag
deployment area.
◇Do not expose the radio to direct sunlight over a long time, nor place it close to heating source.
◇When using your radio, hold the radio in a vertical position with the microphone 3 to 4 centimeters
away from your lips.
◇If you wear a radio on your body when transmitting, ensure that the radio and its antenna are at
least 2.5cm away from your body.

Circuit Description
Power Supply
Power supply of the radio is derived from the battery, which supplies battery B+ after passing through
fuse 3A and then feeds through power switch. The power supplies voltage for three AVRs. IC504
supplies 5V (M5V) voltage for the control circuit. And IC503 supplies 5V (C5V) voltage for the shared
circuit. IC502 supplies voltage for the transmit/receive circuit. In transmit mode, T5C becomes low
voltage and Q502 is turned on to supply 5V (T5v) voltage for the transmit circuit. In receive mode, R5C
becomes low voltage and Q504 is turned on to supply 5V (R5V) voltage for the receive circuit.
Fig. 1 Power Supply Block Diagram
PLL Frequency Synthesizer
PLL circuit generates the first local oscillator signal for reception and RF signal for transmission.
Fig.2 PLL Block Diagram

TC-700 Service Manual
10
1. PLL Circuit
Step frequency of PLL can be 2.5 KHz, 5.0 KHz or 6.25 KHz. A 16.8MHz reference oscillator signal is
divided at IC301 by a counter to generate a 2.5 KHz, 5.0 KHz or 6.25 KHz reference frequency. Output
signal from VCO is buffer amplified by Q301 and divided at IC301 by a frequency divider. The divided
signal is compared with 2.5 KHz, 5.0 KHz or 6.25 KHz reference signal in the phase comparator of
IC301. The output signal from phase comparator is filtered through a low pass filter to generate a level
D.C., and the level D.C. controls oscillator frequency by controlling VCO.
2. VCO
The operating frequency is generated by Q302 in transmit mode and by Q307 in receive mode.
Operating frequency generate a control voltage by phase comparator to control varactor diodes so that
the oscillator frequency is consistent with the MCU preset frequency(D301、D302、D303 and D304 in
transmit mode, and D307、D308、D309 and D310 in receive mode). T/R pin is set high level in receive
mode, and low level in transmit mode. The output from Q302 and Q307 is amplified by Q304 and sent
to buffer amplifier.
3. Unlock Detector
An unlock condition appears if low level appears at MUXOUT pin of IC301. Transmission is forbidden if
this condition is detected by microprocessor.
Receiver
The receiver utilizes double conversion superheterodyne (UHF)/(VHF).
Fig. 3 Receiver Section Configuration
1. Front-End RF Amplifier
The signal from antenna is amplified at RF amplifier (Q207) after passing through a
transmit/receive circuit and a band pass filter. Before passing the first mixer, the amplified
signal is filtered through another band pass filter to remove unwanted signals.
2. First Mixer
The signal from RF amplifier is mixed with the first local from PLL frequency synthesizer circuit at the
fix mixer (IC202) to create a 49.95MHz first IF signal. The first IF signal is then fed through a crystal
filter (XF203) to further remove unwanted signals.
3. IF Amplifier
The first IF signal is amplified by Q206 before passing through crystal filter and by Q204 after crystal
filter and then enters IF processing chip IC204. The signal from IC204 is mixed with the second
oscillator signal again in IC204 to create a 450 KHz second IF signal. The second IF signal then
passes through a 450KHz ceramic filter (wide band: CF201，narrow band: CF202) to eliminate
unwanted signals before it is amplified and detected in IC204.

TC-700 Service Manual
11
4. Narrow band/Wide band Switch Circuit
Pin WCON and NCON of IC500 outputs wide band (high level) and narrow band (low level) controlling
signal respectively to turn on corresponding diode-connector, and to choose ceramic filter CF201
(wide band) or CF202 (narrow band) to filter useless spurious signal.
5. AF Amplifier
The resulting AF signal from IC204 enters base band processing chip IC408. The processed AF signal
is then amplified by an AF power amplifier (IC401) to drive the speaker.
Transmitter
1. AF and Signaling
AF signal from the microphone is amplified and low-pass-filtered in IC402 before it enters base band
processing chip IC408, which also enters CTCSS/CDCSS/DTMF/5-Tone etc signaling generated by
CPU. The IC408 processed mixing signal enters VCO for direct FM modulation (see fig.5).
2. RF Power Amplifier
The transmit signal from VCO buffer amplifier (Q111) is amplified by Q101 and Q102. The amplified
signal is then amplified by the power amplifier Q103 and Q104 (including a two-stage FET amplifier) to
create 4.0W (UHF)/5.0W (VHF) RF power (see Fig. 6).
Fig. 4 APC System
3. Antenna Switch and LPF
Output signal from RF amplifier passes through a low-pass filter network and a transmit/receive switch
circuit comprised of D102，D103 and D104 before it reaches the antenna terminal. D103 and D104 is
turned on (conductive) in transmit mode and off (isolated) in receive mode.
4. APC
The automatic power control (APC) circuit stabilizes the transmit output power by detecting the drain
current of final stage amplifier FET. IC101 (2/2) compares the preset reference voltage with the voltage
obtained from final current. APC voltage is proportional to the difference between auto detect voltage
and reference voltage output from IC101 (1/2). The output voltage controls FET power.

Base Band and Signaling System
The block diagram of signaling section is shown as figure 5.
Fig. 5 AF and Signaling Circuit
1. CTCSS/CDCSS
Transmit: CTCSS/CDCSS signaling produced by CTCSS-PLL pass a low pass filter and then enters
VCXO. CTCSS/CDCSS signaling produced by CTCSS-OUT pass a low pass filter and then mixed with
AF before enters VCO.
Receive: Demodulated signal enters MCU after pass IC404、IC405. MCU then judges whether
CTCSS/CDCSS matches the preset values or not. According the result, the out tone will be controlled
by AFMUTE.
2. 5-Tone and DTMF
Transmit: The signal produced by MCU provides a TX and SP out tone, and is then applied to the
base band processing IC. The signal in mixed with the audio signal and goes to the VCO.
Receive: Demodulated signal is filtered after passing base band processing IC, and then enters
MCU for decoding.
3. MSK
Transmit: MSK signal produced by base band processing IC enters VCO together with AF signal for
modulation.
Receive: MSK input of demodulating IC is sent to AK2346 for demodulation after being amplified. The
demodulated signal is then sent to MCU for decoding.
4. AF
Transmit: AF signal from MIC enters base band processed IC for amplification, pre-emphasis etc.
after being amplified. And then it enters VCO for modulation.
Receive: Demodulated AF signal enters the base band processing IC for amplification, de-emphasis
etc. after being amplified. And then it enters AF power amplifier drived speaker.
Base band processed chip provides functions for processing signal as amplifying, filtering,
emphasizing, scrambling, companding, and amplitude limiting.
