Radio Modes
User Mode
User mode is conventional communication mode. Turn the power on while disconnecting the two SELF
points, the radio enters user mode. (Refer to “TC-500 Owner’s Manual”for details about operation in this
mode.)
Model Set Mode
1. If the radio is in standard model, short out the two MS2 points on PCB and then operate following the
steps (3), (5) and (6). If the radio is in non-standard model, please disconnect the two MS2 points on
PCB and then operate the following steps.
2. To select MS1 (See the initial data table) according to the radio model, if MS1 is 1, short out the two
MS1 points on PCB and continue the following operation. If not, disconnect the two MS1 points and
continue.
3. Short out the two SELF points on PCB and then turn the power on. Two beeps sound.
4. Turn Channel Selector Knob to the corresponding position (1-11) according to the radio model (Refer
to the initial data table).
5. Press PTT key while holding down MONI key to set the model. Channel data and settings are
initialized (Refer to the initial data table).

TC-500 Service Manual

6. Turn off the radio and then disconnect the two SELF points on PCB to complete the model setting.
For example, if MS1 of TC-500-U (450.000~469.995MHz) is 0 (See the initial data table) and its
number refers to 7, then it is unnecessary to short out MS1 and MS2. To initialize its model and
channel data, you can operate as following:
(1) Short out the two SELF points on PCB;
(2) Turn on the radio and turn the Channel Selector Knob to the position 7;
(3) Press PTT key while holding down MONI key;
(4) After data reset, turn off the radio, disconnect the two SELF points and restart to use the radio.
Remarks: The old data (frequency, CTCSS/CDCSS, channel function settings) will be changed
once the model is set, and part of functions will also be changed. Therefore, do not make this
operation unless it’s very necessary, such as changing the EEPROM, etc.

Circuit Description
Frequency Configuration
The receiver utilizes double conversion superheterodyne. The first IF is 21.4MHz and the second is
455KHz. The first local oscillator signal is supplied from PLL circuit. Frequency needed in the transmitter
is supplied from PLL circuit. Figure 1 shows the frequency configuration.
Frequency Range: 136-150MHz 150-174MHz 350-370MHz
370-390MHz 400-420MHz 450-470MHz
Figure 1 frequency configuration
Receiver
The receiver utilizes double conversion superheterodyne.
1. Front-end RF Amplifier
The input signal from antenna is amplified in RF amplifier (Q27) after passing through the
receive/transmit switch circuit and a 3-stage LC band pass filter. The amplified signals are
filtered by a band pass filter (a 3-stage LC BPF) to eliminate unwanted signals before they
go to the first frequency mixer.
Figure 2 receiver section configuration
2. The First Mixer
The signal from RF amplifier is mixed with the first local oscillator signal from PLL frequency

TC-500 Service Manual
10
synthesizer in the first mixer (Q23) to generate a 21.4MHz first IF signal. The first IF signal is then
fed through two monolithic crystal filters (XF1) to remove spurious signals from adjacent channels.
3. IF Amplifier
The first IF signal is amplified in Q22 and then enters the IF process chip IC1. The signal is mixed
with the second local oscillator signal in IC1 to create a 455KHz second IF signal. The second IF
signal is then fed to a 455KHz ceramics filter (CF1) to eliminate unwanted signals before it is
amplified and FM detected in IC1.
4. Audio Amplifier
The demodulated audio signal obtained from IC1 is amplified in IC7 (1/4), and then filtered by low
pass filter Q19 and high pass filter Q20, and then de-emphasized by R130 and C156. The resulting
audio signal passes through a volume control circuit and then is amplified to a sufficient level to
drive the speaker by audio power amplifier (IC8).
5. Squelch
Part of the audio signal from IC1 enters IC1 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 IC1 goes to the analog port of the microprocessor (IC11). IC11 determines whether
to output sounds from the speaker by detecting whether the input voltage is higher or lower than
preset value.
To output sounds from the speaker, IC11 sends a high level signal to the MUTE and AFCO lines and
turns IC8 on through Q12.

matches the preset value and controls the MUTE and AFCO and the speaker sound output
according to the squelch results.
PLL Frequency Synthesizer
PLL circuit generates the first local oscillator signal for reception and the RF signal for
transmission.
1. PLL Circuit
The step frequency of PLL circuit is 2.5KHz or 6.25KHz. A 12.8MHz reference oscillator
signal is divided at IC2 by a fixed counter to produce a 2.5 KHz or 6.25 KHz reference
frequency. Output signal from voltage control oscillator (VCO) passes through buffer
amplifier Q14 and is divided at IC2 by the dual-module programmable counter. The divided
signal is compared in the phase comparator IC2 with the 2.5 KHz or 6.25 KHz reference
signal. The output signal from phase comparator is filtered through a low-pass filter and
passed to the VCO to control the oscillator frequency. (See figure 4)
Figure 4 PLL circuit
2. VCO
The operating frequency is generated by Q16 in transmit mode and by Q8 in receive mode.
The operation frequency generates a voltage through the phase comparator to control the
varactor, so as to keep the oscillator frequency consistent with the preset frequency in
CPU (D2 and D3 in transmit mode and D7 and D8 in receive mode). T/R pin is set high in
receive mode causing Q6 to turn off Q16 and turn Q7 on. The T/R pin is set low in transmit mode.
The output from Q8 and Q16 is amplified by Q14 and sent to the buffer amplifier.

TC-500 Service Manual

Transmitter
1. Transmit audio
The audio signal from microphone is amplified through IC3, and then pre-emphasized , and then
filtered by another low-pass filter（separate filter）(Q25 and Q24) to eliminate the frequencies over
3KHz. The resulting signal enters the VCO for direct FM modulation. (See figure 5)
2. CTCSS/CDCSS Encoder
The necessary frequency for CTCSS/CDCSS encoder is generated by IC11 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 splitter. (See figure 5)
Figure 5 transmit CTCSS
3. RF amplifier
The transmit signal obtained from VCO buffer amplifier Q14 is amplified by Q15 and Q17. This
amplified signal is passed to power amplifier Q32 and Q31, and is capable of producing a 4.0W RF
power.
4. Antenna Switch and LPF
The RF amplifier output signal is passed through a low-pass filter network and a transmit/receive
switch circuit before it is passed to the antenna terminal. The transmit/receive switch circuit is
comprised of D11 and D12. D11 and D12 is turned on in transmit mode and off in receive mode.
Power
The 5V reference power supply for the control circuit is derived from an internal battery. The reference
power provides a 5V supply in transmit mode [T_V], a 5V supply in receive mode [R_V], and a 5V supply
shared in both modes based the control signal from the microprocessor.
Control System
The IC11 CPU operates at 7.3728MHz.
