The radio in User Mode enters PC Programming Mode through specific protocol based communication

with the programming software. In this mode, radio functions and adjustment parameters can be set


6

through the programming software (including User Version and Factory Version).

The operation procedures are as follows:

1) Install PC programming software and its driver dedicated for TC-320 before your initial use.

2) Connect the USB port of PC with the Mini USB jack of the radio using a programming cable.

3) Turn on the radio.

4) Launch the programming software to perform reading or writing operation.

Note:

1) When reading/writing data is in progress, red/green LED glows; when reading/writing data is

completed, red/green LED goes out.

2) During the operation, if any abnormal situation occurs or no reply is given within a period, the

reading/writing operation will fail and an error message window will pop up.

Wired Clone Mode

1. Description

Wired Clone Mode is an independent mode. To access other modes, you must restart the radio.

Wired Clone Mode covers User Clone Mode and Factory Clone Mode.

1） User Clone Mode:

Connect two radios using a clone cable. Power on the source radio while holding down SK, and it

will enter User Clone Mode after 2 seconds. The target radio can be directly turned on to enter user

mode. In this mode, data stored in EEPROM of the source radio will be cloned to EEPROM of the

target radio. The data transferred only involves channel data and common parameters, excluding

adjustment data, version and serial No. of the model.

2） Factory Clone Mode:

Connect two radios using a clone cable. Power on the source radio while holding down SK, and it

will enter User Clone Mode by default after 2 seconds. Press SK afterwards to switch to Factory

Clone Mode. The target radio can be directly turned on to enter the mode. The data transferred

covers all data in EEPROM other than serial No, with flag of manual adjustment switch included.

2. Process

Process of Wired Clone:

1) The LED flashes red once after the source radio enters Wired Clone Mode. Hold down PTT to clone

data to the target radio.


7

2) During communication, LED of the source radio glows red, and LED of the target radio glows green.

When communication finishes, LED of the source radio glows green and LED of the target radio goes

out, indicating that both radios are ready for another cloning operation.

3) If any abnormal situation occurs during cloning, the source radio will stop cloning and its LED will flash

orange, indicating both radios are ready for another cloning operation.

4) When the communication ends, the source radio goes back to standby status. Hold down PTT again

to begin another cloning.

Manual Adjust Mode

Hold down PTT and SK on the radio while powering it on, and the radio enters Manual Adjust Mode.

(Note: This operation is subject to the option Panel Test Mode in the programming software. When this

option is unchecked, the radio will be unable to enter the adjustment mode. It helps avoid change of

parameters and degradation of radio performance caused by user’s misoperations. )

Keep this option unchecked after values are well adjusted from factory, to avoid any unexpected change

of values. The adjustment values can be reset and changed in Factory Mode only.

Description of adjustment:

Figure 1

TX Section: The audio signal from MIC is sent to the MCU chip (U601) directly. The baseband signal

processing circuit in U601 converts the amplified audio signal to digital signal via A/D conversion, and

then converts the digital signal to modulation signal via D/A conversion after all processing procedures

such as filtering, signal compression, encryption, pre-emphasis, TX gain control and amplitude limiting

are completed. Then the modulation signal from MCU passes through the low-pass filter circuit and goes

to VCO for direct frequency modulation.

The modulated HF carrier signal passes through the buffer amplifiers (Q104 and Q406), and goes to the

amplifier (Q401) through the RF switching diode (D616). Then the amplified RF signal enters the

low-pass filter circuit through the switching diode (D401) after it is further amplified by the driver (Q402)

and final-stage power amplifier (Q403), and then it will be finally transmitted via antenna after high-order

harmonics are removed. The RX-TX switch circuit is composed of D401 and D501.


10

RX Section: RF signal received via the antenna is fed to the bandpass filter (composed of SAWF501

and SAWF502) to filter out unwanted out-of-band interference signal, and then amplified by LNA Q503.

The amplified signal is then fed to the bandpass filter (SAWF503) to further filter out unwanted

out-of-band interference signal. The desired RF signal is mixed with the first local oscillator signal

(output from VCO) by Q505. The newly generated signal is processed by the crystal filter (XF501) to get

the first IF signal (21.7MHz). After amplified by Q506, this IF signal enters U608 to be further mixed with

the second LO (local oscillator) signal and to generate the second IF signal (450 KHz). This second IF

signal is demodulated by U608 to output audio signal, which is sent to MCU for A/D conversion and

filtering. Afterwards, the audio signal is divided into two flows. One flow is processed by CTCSS/CDCSS

decoder; the other is restored to audio signal through filtering, de-emphasis, decoding, signal expansion

and D/A conversion. Then the restored audio signal is amplified by the audio power amplifier (U301) to

drive the speaker directly.

Power Supply Section: The 3.8V battery voltage is converted to two flows of 3.0V DC voltage by the

LDO module (U602), that is, VCC and V_SAVE. VCC powers CPU while V_SAVE controls VT and VR.

VT goes through Q604 and Q601, and outputs 3V voltage for TX circuit under the control of TX-CTRL;

VR supplies 3V voltage for RX circuit under the control of Q604 and Q602. VDD (3V) supplies the PLL

U101 and XT101.

2. Realization Methods of Basic Functional Modules

2.1 PLL Frequency Synthesizer

The PLL circuit mainly provides the local oscillator signal for RX and RF carrier signal for TX. It is

composed of VCO and PLL processor, allowing frequency tracking and channel switching under the

control of MCU signals.

1） PLL


11

Figure 2

The PLL circuit generates RF carrier signal for TX and the first local oscillator signal for RX.

PLL: Step frequency of the PLL circuit is 6.25 KHz, 10.0 KHz or 12.5 KHz. In U101, the 21.25MHz

reference oscillator signal is divided into 6.25 KHz, 10.0 KHz or 12.5 KHz reference frequencies via a

fixed counter in PLL. Processed by the buffer amplifier, the signal output from the VCO (TX/RX VCO)

enters PLL. The amplified signal is further processed in PLL by the variable frequency-divider. Then the

signal is compared with the reference frequency in the phase detector (PD) of PLL. The signal from the

PD passes through a low-pass filter, and then is sent to the varactors (D101 and D102) of VCO so as to

control output frequency. Then the RF signal is processed by the buffer amplifiers (Q104 and Q406),

and controlled by D616 and D617 to only serve as RF signal or RX first local oscillator signal.

2） VCO

VCO section is realized by the oscillator circuit of three-point capacitance. TX VCO and RX VCO share

the same oscillator circuit. In TX mode, Q103 is cut off and C130 gets invalid; in RX mode, Q103 is

turned on and C130 gets valid.

Note: If the PLL is unlocked, the LD pin of U101 outputs low level. If the microprocessor detects such

situation, TX/RX operation is prohibited, and an alarm sounds.

2.2 RF Power Amplifier Circuit (TX Section)

The modulated carrier signal from VCO is pre-amplified by Q104 and Q406, and controlled at D617 and

D616. Then it is processed by the front-stage amplifier Q401, the pre-driver amplifier Q402 and the

final-stage amplifier Q403 respectively. Afterwards, the amplified RF signal enters the low-pass filter

(LPF) circuit through diode D401, and then is transmitted via the antenna after ultroharmonics are

removed.

APC circuit is composed of Q404, Q405 and U401. U401 controls the bias voltage at the gates of Q402

and Q403, to control TX current and to further regulate power.

2.3 RX LNA and Mixer Circuit (RX Section)

The block diagram of the RX circuit is shown as below:

Figure 4


13

Desired and undesired RF signals received via the antenna are fed to the bandpass filter (composed of

SAWF501 and SAWF502) to filter out undesired out-of-band interference signal. Then the desired RF

signal is amplified by LNA Q503, and goes through the bandpass filter ( to filter out undesired

out-of-band interference signal. The desired RF signal is mixed with the first local oscillator signal

(output from VCO) by Q505. The newly generated signal is processed by the crystal filter (XF501) to get

the first IF signal (21.7MHz).

After amplified by Q506, this IF signal enters U608 to be further mixed with the second LO (local

oscillator) signal and to generate the second IF signal (450 KHz). Then the second IF signal is

demodulated by U608 to output audio signal, which is sent to MCU for A/D conversion and filtering.

Afterwards, the audio signal is divided into two flows. One flow is processed by CTCSS/CDCSS decoder;

the other is restored to audio signal through filtering, de-emphasis, decoding, signal expansion and D/A

conversion. Then the restored audio signal is amplified by the audio power amplifier (U301) to drive the

speaker directly.

2.4.1 MCU Control Circuit

MCU control circuit is composed of MCU, EEPROM, keys and etc. This section has the following

functions: to initialize data of the radio and save data to EEPROM; to detect battery voltage and signals

from external keys, LD and VOX, and to make response; to transmit required data to PLL based on the

channel encoding status; to switch and control RX/TX based on the input PTT signal; to switch the

squelch circuit on/off based on the input signaling decode signal and squelch level signal; to control

circuits of high/low power switch, audio power amplifier, VCO power supply, RX power supply and TX

power supply; (for programming) to communicate with PC via RXD/TXD based on the RS232 protocol,

and transmit/receive data to/from PC.

2.4.2 Signal Processing Section

a. TX Baseband Processing The audio signals input from MIC are divided into two flows. One flow

serves as the signal of VOX detection by Q508 and D612; the other enters U601, and then is converted

into digital signal by analog-to-digital conversion (ADC). Afterwards, the digital signal will go through a

series of processing including low-pass filtering, AGC, companding, high-pass filtering, encrypting and

pre-emphasizing. Finally, the signal is processed by the active low-pass filter and then sent to VCO for

modulation after it is converted by digital-to-analog conversion (DAC).

b. RX Baseband Processing

After entering U601, the DEMOD signal derived from IF demodulation is converted to digital signal via

analog-to-digital conversion (ADC), and then is sent to the digital low-pass filter. The signal is divided

into two flows. One flow is processed by CTCSS/CDCSS decoder; the other is processed by high-pass

filter, and then is subject to processing procedures such as de-emphasis, decryption, and signal

expansion, and finally is output as audio signal after digital-to-analog conversion.

2.4.3 Audio Power Amplifier

The audio signal output from U601 is amplified by the audio power amplifier (U301) to drive the speaker

directly.

Adjustment Description Required Test Instruments:

Radio communication test set (HP8921) 1 set

10V/3A regulated DC power supply 1 set

Digital voltmeter 1 set

Ammeter 1 set

Preparations:

Place the board to be tested on the test fixture (please ensure good connection between each test point

and the fixture), and connect the board to a power supply with DC voltage of 3.8V.

Wired Clone

1. Operations:

1) Connect two radios using a clone cable. Power on the source radio while holding down SK, and it will

enter Wired Clone Mode after 2 seconds. The target radio can be directly turned on to enter user

mode.

(2) In Wired Clone mode, press SK of the source radio to switch between User Clone Mode and Factory

Clone Mode (check the Factory Clone Mode option when programming or you will fail to switch.).

3) Hold down PTT key of the source radio to clone data to the target radio. You can clone the data to

multiple target radios in the same way.

2. LED Indications:

Status of the source radio:

During the cloning process, the LED solidly glows red. Once it finishes, the LED will solidly glow green.

Clone errors:

(1). User clone. Once clone begins, frequency band and radio ID (Model ID) will be checked. The LED

glows orange for 2 seconds and then goes out to indicate a failed check. If the check is successfully

carried out but error occurs during data cloning, the LED will flash orange. In this situation, press any

key other than the Power Switch to turn it off.

(2) Factory Clone: If error occurs during data cloning, the LED will flash orange. In this situation, press

any key other than the Power Switch to turn it off. Hold down PTT to initiate a new clone process.

Status of the target radio:


34

The LED solidly glows green during the cloning process and goes out once it finishes.

3. Differences between Factory Clone Mode and User Clone Mode:

(1) User Clone Mode: Only clone the data of user mode. Test parameters like adjustment frequencies,

adjustment items and baseband parameters will not be cloned.

(2) Factory Clone Mode: Clone all the data excluding serial No.

4. Instructions:

(1) Error will occur when data is cloned without cable connection. Please refer to 2-(2).

(2) Error may occur during test data clone in Factory Clone Mode if you wrongly press the side key and

switch into User Clone mode (LED flashes red once).

(3) If battery of the source radio runs low in clone mode, red LED will flash and low battery alert will be

given as well.

Adjustment

1. Description of Adjustment Procedures:

(1) Power on the radio while holding down PTT and SK for more than 2s to enter adjustment mode (the

LED flashes orange). After the keys are released, the radio will enter the adjustment item in this mode

(the item entered depends on the position where the Channel Selector knob locates). And the LED will

glow red/green for adjustment items in TX/RX groups respectively.

(2) Or connect the programming cable to the radio for real-time adjustment in PC mode.

2. Description of Adjustment Items:

(1) Switch of Wide/Narrow Bandwidth and Frequency in an Adjustment Item:

In an adjustment item, short press SK to switch between wide and narrow bandwidth. The default

adjustment point is the first frequency (low frequency) of current bandwidth. Short press PTT to switch

among different frequencies after selecting a bandwidth.

(2) Adjustment Items Include:

TX Items:

TX Frequency Tolerance and VCO Lock Voltage.

Note: These items are adjusted outside the adjustment mode via hardware.

TX Low Power, TX High Power, CDCSS Waveform, CDCSS Deviation, CTCSS Deviation (low), CTCSS

Deviation (medium), CTCSS Deviation (high), TX Low Voltage Threshold and Max. Deviation.

Note: These items are adjusted inside the adjustment mode.


35

RX Items:

VCO Lock Voltage (outside the mode), Squelch and RX Low Voltage Threshold.

3. Specific Operations and Requirements: (1) Conventional Adjustment Items (outside the adjustment mode): TX Frequency Tolerance, VCO Lock

Voltage.

(Note: The configuration file has preset CH1, CH2 and CH3 as wide bandwidth with low, medium and

high frequency respectively and CH4, CH5 and CH6 as narrow bandwidth with low, medium and high

frequency respectively. Make sure the antenna or load is connected before adjustment.)
