Figure 3.1 Receiver Diagram
Receiver Front End
The signal coming from the antenna passes through the
RX/TX switch circuit (D11, D12, D21, D17), and sends into IC1
(RDA1845) to demodulate, and then output audio signal.
RX Audio Signal Process
The audio signal demodulated by IC1 (RDA1845) passes
through the volume potentiometer, and comes to audio power
amplifier U31 (TA7368F).
Squelch Circuit
The third pin of IC1 (RDA1845) sends out signal to MCU
which can identify the noise level and control the squelch circuit.
Audio Power Amplifier
IC1 and the periphery components consist of BTL audio
power amplifier circuit.
Base electrode of Q31is the control end. High level: On; low
level: Off.
Receiving audio signal, voice annunciation signal, alert tone
signal and emergency alarm signal gather together and are
amplified by audio amplifier to drive the speaker. Among these
signals, the emergency alarm cannot be adjusted by the volume key.
The impedance of the speaker is 8 Ω.
CTCSS Process
The 33rd pin of IC1 (RDA1845) outputs CTCSS/CDCSS signal to
MCU to decode.

R231, R232 and R233 are used to test the power amplifier
current. IC3A is the sampling amplifier for the power amplifier
current. IC3B is the power comparator amplifier.
If the TX output power is too high, the power amplifier
current and IC5A output voltage increase; IC5B output voltage
decreases, and the offset voltage added to Q21 and Q22 decreases,
which cause the TX output power decreases and vice versa. Thus,
the TX output power can keep stable under different working
conditions.
By changing the voltage inputting to IC5B, the MCU can
adjust the power.
TX Voice Signal Process
MIC signal passes through the inner and outer MIC Switch
Circuit. This signal first is sent to U32U for filter and amplifier, and
then is sent to the 5th pin of IC1 (RDA1845) for carrier modulation.
3.4 Principle of Frequency Synthesizer
13MHz reference frequency signal provided by X1 is sent to
the internal reference divider of IC1 (RDA1845) for division, and
then is sent to the internal discriminator and the internal VCO to be
divided by decimal fraction divider, and then this signal comes to
phase comparator. The internal VCO is controlled by the output
control signal to make the frequency of VCO equals to the
designed frequency.
3.5 VoiceAnnunciation Circuit
This product has voice annunciation function, which is
especially useful at night or in the dark environment.
IC2 is the voice storage chip, which stores voices such as
channel annunciation and so on. When switching to the next
channel, the radio will annunciate the current channel number.
When pressing “Voice Annunciation” Key, the radio will
annunciate the channel number again.
If Voice Annunciation is enabled, press “Voice Annunciation”
Key in the standby state, the radio will annunciate the current
channel number. Press and hold that key to restart the radio and
change the type of voice annunciation. When repressing the key to
restart the radio, the radio will annunciate again and again in the
order of “Chinese woman voice-English woman voice-no sound”.
3.6 Power Supply
The radio uses 7.4V, 1100mAh Li-on battery as the power
supply. The transmitter power amplifier circuit (Q21, Q22) and the
receiver audio power amplifier (U31) directly adopt the battery for
power supply. Other circuits are powered by 3V regulated voltage.
IC6: 3V low dropout, micro-power regulator, supplies 3V
voltage for the radio.
Q12: 3T switch, controlled by MCU.
3T: Supplies power for front end of the TX.
Q27: 3R switch, controlled by MCU.
3R: Supplies power for RF amplifier, mixer, IF processing
unit, and audio signal processing unit etc. of receiver.

CTCSS/DCS Signal Encoding and Decoding
The CTCSS/DCS signal (output from pin 17, PWM wave)
generated by MCU passes through R624, R623, C616 and C617
filter and is sent to RDA 1845 for modulation.
The CTCSS/DCS signal from the receiver is sent to MCU for
modulation. The MCU will judge whether the CTCSS/DCS signal
in the receiver matches with the preset CTCSS/DCS signal of the
radio, and determines whether to turn on the speaker or not.
CTCSS
CTCSS（Continuous Tone Control Squelch System, CTCSSS
for short）is the squelch control system which is modulated on the
carrier, and uses the continuous sub-audio signal as the guide
frequency. If CTCSS is set, the communication between the
transmitting and receiving radios can be realized only when the two
radios have set the same CTCSS frequency. In doing this,
disturbance from other signals can be avoided.
This radio has 39 groups of standard CTCSS frequencies for
your selection (these CTCSS frequencies are compatible with any
of the CTCSS within 67-254.1Hz). See table 3.1.
The CTCSS signal (PWM wave) generated by MCU passes
through the low pass filter consisted of by RC to remove high
frequency components (above 300Hz). Then the resulting signal is
sent to VCO for modulation.

DCS
DCS (Digital Code Squelch), which is used to control
squelch, is a series of continuous digital codes modulated on the
carrier together with voice signal. If DCS is set, the speaker can
only be opened when the radio receives signal with the same DCS
to avoid disturbance of unwanted signals.
This radio has 83 standard codes (normal and inverse) for
your selection. See table 3.2.
DCS signal (PWM wave) is generated by MCU. It passes
through the low pass filter consisted of by RC to remove high
frequency components (above 300Hz), and then the processed
signal is sent to VCO and TCXO for modulation, with HF
components of the DCS signal being modulated by VCO, and the
LF components of the DCS signal being modulated by TCXO.
The DCS signal coming from the receiver is sent to MCU for
decoding. MCU checks if the DCS code in the received signal
matches the preset DCS of the radio, and determines whether to
open the speaker or not.

4.1.3 CTCSS and DCS
CTCSS/DCS is a kind of sub-audio and digital sub-audio
signal, which can realize the function of call selection and group
call. On one channel, the communication can only be realized when
the radios have the same CTCSS/DCS code. CTCCS/DCS code is
preset.
4.1.4 TOT Transmitting Timeout
TOT can prevent the user from continuously talking overlong
and prevent the current channel from being occupied overlong so as
to affect the group communication.
If you continuously transmit longer than the preset TOT time,
the radio will stop transmitting and make an alert tone. To stop the
warning tone, release the PTT button.
4.1.5 TOT Pre-alert
The radio will make an alert tone in advance before the TOT
terminates the transmission. If the continuous transmitting time
exceeds the time preset by the dealer, the radio will send out an
alert tone, but the communication can be continuing until the TOT
time is over.
4.1.6 TOT Repress
The function can be set to stop transmitting after the TOT
time is over. When the TOT time is over, and press the PTT button
again during the pre-set time, the radio will send out an alert tone
and stop to transmit.
4.1.7 TOT Reset
This is the interval between the pre-set TOT time is over and

sends out, and the transmission is disabled.
4.1.12 PC Program
The user can set the functions and adjust the parameters of
the radio through the program software KSP260.
4.1.13 Wired Clone
The data stored in the radio can be transmitted to the radio
with the same type with the wire.
4.1.14 Squelch Circuit Level
The squelch circuit is used to mute the speaker when no
signal is received or the receiving signal is very weak. If enabled,
the sound from the speaker will be heard; if disabled, no sound will
be heard. The squelch level determines when the squelch can be
turn on or off during the receiving. If the squelch level is set too
high, the weak signal cannot be received completely; if it is set too
low, your radio will often be interrupted by the noise or other
irrelevant signals. The squelch level can be set to 0-9.
4.2 Functional Parameters Setting (PC mode)
