z RDA Chip Circuit
This chip is highly integrated. Its function includes voice signal
processing/modulation/demodulation, DSP, VCO, PLL, LNA and RF IF. The voice signal from MIC
goes to RDA chip for amplification. Next, the amplified voice signal will undergo a series of
processing including A/D conversion, filtering, pre-emphasizing, gain control, amplitude limit and D/A
conversion. Then the analog voice signal is delivered to VCO and amplified to a signal with 8dBm.
When the RX RF signal enters this chip, it would experience demodulation, filtering, de-emphasizing
and gain control. Finally, the signal is output to the audio amplifier.

Service Manual
Circuit Description
z TX Circuit
The modulated RF signal from RDA chip goes to Q407 and Q402 for amplification, and then further
amplified by Q403. Then the amplified signal is delivered to low-pass filter to filter out the high-order
harmonics. Finally, it is sent via the antenna.
z RX Circuit
After going through LPF and amplitude limiter, the RF signal received from the antenna enters Q501
LNA for amplification. Then the BPF will filter the signal to remove other unwanted signals. The
resulting signal is delivered to RDA chip for demodulation. After that, the voice signal from
demodulation is output U301 for amplification, which is finally output from the speaker.
z Power Circuit
LDO U619 and DO U621 convert the 3.8V power supply into two 3.3V power supplies, powering
VCC and VDD respectively. VCC powers CPU, while VDD powers RDA chip. Then Q409 converts
the 3.3V power supply to VT to power the TX circuit.

After entering RDA chip via MIC, the voice signal will undergo A/D conversion to get digital
signal, which will be delivered to DSP for further processing such as filtering, amplification,
amplitude-limiting and pre-emphasizing. Then the resulting voice signal is modulated to the internal VCO
and output after being amplified by the driver amplifier. At the RX end, the received RF signal will go to
LNA for amplification first, and then go to IF demodulation circuit to get demodulated voice signal. After
gain control, such signal is converted into digital signal, which will enter DSP for further processing such
as filtering, amplification and de-emphasizing.
The function of RDA is subject to MCU U622 and its reference clock signal is from 26MHZ crystal
oscillator. This chip is applicable to UHF (400~520MHZ) and VHF (134~174MHZ). The NF can be up to
3dB and IIP3 up to -6dBm, meeting GB and FCC requirements. Its RF output may reach up to 8dBm.

7.2 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
7.2.1 Instructions:
z Connect two radios using a cloning cable. Simultaneously hold down SK (Side Key) to power on the
source radio so that the wired clone mode will be entered after 2 seconds, and then press SK to
switch to factory wired clone mode (when the wired clone mode is entered, the user wired clone
mode is defaulted); then directly power on the target radio to enter the user mode.
z The Status Indicator flashes red once after the source radio enters Wired Clone mode. Press PTT to
clone data to the target radio.
z During communication, the Status Indicator of the source radio glows red, and the Status Indicator of
the target radio glows green. When the communication ends, green LED of the source radio glows
and the green LED of the target radio goes out, which indicates the preparation for another clone.
z If any abnormal situation occurs during communication, the source radio will flash orange Status
Indicator and will stop communication for another cloning.
z When cloning ends, the source radio goes back to the standby status. Press PTT again to begin
another cloning operation.
7.2.2 LED Indication during Cloning
z Orange LED flashes: an error occurs during cloning. In this case, press any key other than the power
switch to turn it off.
z Green LED glows: the cloning is done successfully.

Service Manual
Description:
z Squelch On/Off: to set the threshold value for enabling/disabling the squelch function.
z Calibrate Wide/Narrow SQ Open/Close: to tune the squelch threshold to compensate the circuit
difference. It is recommended to apply the same value to one model. Increasing the value may
tighten the squelch, while decreasing may loosen it.
z Skip RX/TX High/Low Pass: to configure the audio filter (0: not skip; 1: to skip one filter; 2: to skip the
other filter; 3: to skip two filters).
z Pre-emphasis: to configure the pre-emphasis function.
z Skip CTCSS/CDCSS High/Low: to set whether to skip CTCSS/CDCSS filter.
z CTCSS/CDCSS High Pass Filter: to configure the parameters of CTCSS/CDCSS filter.
z Wide/Narrow Noise Detect High/Low: to configure the noise detection threshold.
Note:
It is recommended to set the Squelch Off to -121dBm (Wide) or -120dBm (Narrow), and set the
Squelch On to -122dBm (Wide) and -121dBm (Narrow). When the values from your actual test vary
greatly with those in the above table, you can calibrate this problem by making Wide/Narrow SQ
Open/Close.
7.4 Method and Procedure:
7.4.1 Description of Tuning Procedures
Simultaneously hold PTT, SK and Power On/Off Key for more than 2s to enter tuning mode (Status
Indicator flashes orange). After the keys are released, the radio will enter the tuning item in this mode
