Figure 3.5 IF System
The receiver front terminal
Signals from the antenna pass through the low pass filter
consisting of L104, C546, L103, C545, L102, C534 and the RX/TX
switch (D51); and then undesirable out-of-band signals will be
filtered out at the band pass filter (BPF) consisting of L104, C546,
L103, C545, L102, C534; then signals are amplified at the low noise
amplifier (LNA) consisting of Q81 and its peripheral components.
The output of LNA is sent to the first mixer (Q79) through the
BPF filter consisting of L115, C541, D63, C528, C591, L114, D62,
C527, C590, L113, D60 and C526.
The First Frequency Mixer
After mixing the receiving signals and the first local oscillation
st
signals from the frequency synthesizer, the 1 IF signals (51.65MHz)
st
are generated. The 1 IF signals pass the crystal filter (XF2), which
will filter the signals of adjacent channel and those out of band, and
are sent to the IF amplifier.
IF Circuit
st
The IF signals from the crystal filter are amplified at the 1 IF
amplifier (Q78), and then are sent to the IF processing IC (U9,
nd nd
TA31136FN). The IF IC consists of the 2 frequency mixer, the 2
local oscillator, IF amplifier, limiter, phase frequency detector, and
noise amplifier.
th
TCXO (X4, 12.8MHz) selects the 4 harmonic wave 51.2MHZ
nd nd
as the 2 local oscillation signal source after amplification. The 2
st
local oscillation (51.2MHz) and the 1 IF signal (51.65MHz) are
nd nd
mixed at U9 to generate the 2 IF (450MHz). After the 2 IF signal
is amplified and its amplitude is limited inside U9, and then filtered
at porcelain filter (wideband CF4/Nattowband 3, 450kHz) and then
sent to U9 to demodulate the output audio signals which are finally
th
output from the 9 pin of U9.
Receiver Audio Signal Processing
IC13, IC12, IC16, IC15 and their peripheral circuit compose the
receiver audio signal processing circuit. After being sent to IC13
from U9 for amplification Audio, the audio signal is sent to IC15
CTCSS signaling filter circuit for waveform shaping and then sent to
MCU; and it is simultaneously sent to IC12 and through IC12
amplification, deemphasis, filtration to remove high frequency and
low frequency elements in the audio, only audio components of
300--3000Hz are kept to be sent to audio power amplifier (U9) after
volume potentiometer adjustment, and simultaneously sent to MCU
through IC15 (2 tone/5 tone filtration circuit).
Squelch Circuit
The audio signal output from the demodulation of U9 is sent
back to U9 internal noise amplifier and composes the frequency
selection noise amplifier together with C320, Q77, R167, C439 and
C319. Filtered from the demodulation signals, the noise is changed
into DC level by D57 demodulation after amplification by Q77 and
then sent to MCU, which distinguishes the noise volume so as to
decide whether to enable the squelch, which achieves the control of
the squelch.
Audio Power Amplifier
Q92 and peripheral compose the BTL-audio and power
amplifier.
The audio receiving signals, voice indication signals, indication
tone signals and warning tone signals are converged to be
amplified by the audio power amplifier to drive the speaker.
Speaker impedance: 16Ù
Q95: Receiving audio signal switch
Note: No terminal of the speaker can be grounded!
CTCSS signaling filter
The U9 Demodulation output audio signals may contain CTCSS
(continuous tone coded squelch system) or DCTCSS (Digital coded
squelch) signals. The frequency spectrum of CTCSS/DCS is 20-
250Hz. The filtering circuit constructed by IC16can filter out the
signals out of the CTCSS/DCS frequency spectrum to ensure MCU

Figure 3.9 Transmitter Audio Circuits
R512, R513, R514 are the amplifier current checker; IC10A the
sample amplifier of the amplification current. IC10B is the power
comparison amplifier.
If the transmitter output power is too high, the amplifier current
will increase, IC10A output will mount, IC10B output voltage
decrease, the offset voltage added to Q67 and Q68 will decrease,
and then the transmitter output power will decrease. Vice versa,
such can ensure steady transmitter output power in different
working circumstances.
MCU changes the voltage input to IC10B to set the power.
Transmitter Audio Signal Processing
IC14, IC12 and the peripherals components compose the
transmitter audio processing circuit. The audio signals from MIC are
amplified to be sent to MCU after the demodulation (VOX signal);
simultaneously they are amplified after preemphasis, amplitude limit
and filtration in the C12 where they have been sent there through
the ACC circuit and finally sent to VCO modulation together with
CTCSS/DCS for modulation.
J2 is the external MIC socket, when the external MIC is used,
the internal MIC will be off automatically while the internal PTT will
remain activated.
Figure 3.10 Frequency Synthesizer
The radio adopts Phase Locked Loop (PLL) frequency
synthesizer.
The frequency synthesizer consists of standard oscillator,
voltage controlled oscillator (VCO), programmable frequency
demultiplier, phase comparator, and low pass filter.
IC9 (ADF4111) is PLL integrated circuit, including
programmable reference frequency demultiplier, programmable
frequency demultiplier, phase comparator, and charge pump.
R334, C464, R333, R311, C448, C484 and R336 construct the
low pass filter.
The standard frequency is supplied by X4 (TCXO, 12.8MHz).
The standard frequency from TCXO (Temperature Control
Transistor Oscillator) is demultiplied by the programmable reference
frequency demultiplier at IC9 to acquire 6kHz or 6.5kHz reference
frequency (controlled by MCU according to the preset channel
frequency).
The oscillation frequency from VCO is sent to IC1, and
demultiplied by programmable frequency demultiplier and
compared with reference frequency to acquire the error signals.
Then pass the low pass filter and are sent to VCO to change VCO
oscillation frequency to the preset value, and then VCO is locked.

Check Loss of Lock: When PLL is in loss of lock, IC pin14
sends out low level signals to MCU, which controls the transmitter
not to transmit and initiate warning tone.
3.5 Voice Prompt Circuit:
The radio features voice prompt, which is very useful at night or
in the environment of dim light.
The internal memory IC of MCU is provided with voices like
channel indication, etc., each time switch a channel, the speaker
will prompt the current channel number by voice prompt.

The radio stores 16 channels.
4.1.2 Scanning Channel Function (this function can be
disabled by the programming software)
1) Press the key set to the function of scan to enter the
scanning function. During the scanning, the radio will check signals
of each channel to the signal is found, and then the radio will stay
on the channel with signals till the signal disappear. If the time delay
between the signals disappearing and the scan is set, the radio will
remain on the channel when any signal is received during the
delayed time.
The scanning function can be used only when at least one
channel is programmed and the scanning is valid.
2) Response channel (the transmitting channel when scanning)
during the scanning set by the dealer has the following options:
. The start channel
Press PTT or the CALL key or enable VOX transmitting during
the scanning or when the scanning stays, the radio will transmit
signals on the channel under scanning.
. Start channel + current channel (when response channel is
enabled)
If pressing PTT or the CALL key or enabling VOX transmitting
during the scanning, the radio will transmit signals on the channel
under scanning.
If pressing PTT or the CALL key or enabling VOX transmitting
when the scanning is staying, the radio will transmit signals in the
current channel.
. Designated channel
If pressing PTT or the CALL key or enabling VOX transmitting
during the scanning or when the scanning stays, the radio will
transmit signals in the designated channel.
. Designated channel + current channel (when response
channel is enabled)
If pressing PTT or the CALL key or enabling VOX transmitting
during the scanning, the radio will transmit signals at the designated
channel.
If pressing PTT or the CALL key or enabling VOX transmitting
when the scanning is staying, the radio will transmit signals in the
current channel.
1 . Last received call channel
When pressing PTT key, the radio will transmit signals on the
channel of the last received call.
2 . Last used channel
When pressing PTT key, the radio will transmit signals on the
channel where the last transmitting was made.
3 . Last used channel + current channel (when response
channel is enabled)
If pressing PTT or the CALL key or enabling VOX transmitting
during the scanning, the radio will transmit signals on the channel
where the last transmitting was made.
If pressing PTT or the CALL key or enabling VOX transmitting
when the scanning stays, the radio will transmit signals in current
channel.
Priority scan:
During the scanning, if priority channels of the radio have been
set, even if the normal channels are receiving signals, the radio will
scan the priority channels according to the preset time of scanning,
when the priority channels receive signals, the radio will
automatically switch to the priority channels and stay there till the
signals disappear, the dealer has set the time delay between the
signal disappearing and the continuing scanning, if the scanning
nd st
stays on 2 priority channel, it will scan back 1 priority channel, on
which if it stays, no channel will be scanned back.
Excrescent channel (temporary) deletion
If the scanning stays on a certain channel, you can press the
key programmed for deletion of excrescent channel (temporary) to
temporarily delete the channel for the scan list, if you press the

CTCSS/DCS signals as being used in your radio can receive the
signals you transmit.
4.1.4 TOT function
1) TOT timer:
a) The purpose of the time-out timer is to prevent any person
from overlong using a channel to speak and to prevent radio from
too long continuous transmitting.
b) TOT timer indicates the time allowed for the radio to
continuously transmit signals. If the allowed time is exceeded, the
radio will alarm and stop transmitting.
2) TOT key:
a) It regulates the time span of prohibited transmitting after the
action of the TOT timer.
B) During the time span of prohibited transmitting, if pressing
the PTT key or the CALL or starting the VOX, indication tone will be
generated and the transmitting will be prohibited.
3) TOT Pre-alarm
a) The radio will alarm in advance before the TOT timer stops
the transmitting.
b) After the alert, if the transmitting time exceeds the preset
time, the TOT timer will act.
4) TOT Reset:
a) It regulates the time delay from PTT key releasing to the TOT
timer resetting.
b) If the time of releasing the PTT key is shorter than that of the
resetting time, the countdown will continue.
4.1.5 Auto Power Saving
The dealer can set the power-saving mode of the battery by
programming.
Provided that the function is enabled, the radio will be in the
power-saving mode in 10 seconds if no signal is received or no
operation is carried out. When any signal is received or any
operation is carried out, the radio can automatically quit this mode.
Power-saving modes: short, med, long and off.
Setting the power-saving function of a battery can reduce the
power consumption of the battery.
4.1.6 Low Power Warning
Receiving low power warning: If the battery power is lower than
the preset value during receiving, the radio will produce a alert tone
of Doo every 15 seconds.
Transmitting low power warning: When the battery power
appears low, the indicator flashes. If the battery power is lower than
the preset value during transmitting, the status indicator flashes red.
If the battery level is too low, the radio cannot transmit signals.
4.1.7 Squelch enabled function
If no signal is received, the squelch circuit of the radio will
prevent the speaker from making any sound.
Press the function key for squelch off switch ,you can disable
the squelch control circuit and the speaker will produce continuous
sound (whether signals are received). This operation is very useful
for adjusting volume or receiving weak signals (avoiding
discontinuous sound due to weak signals).
Press the function key for squelch on switch , the green light
will be on and the radio is in the monitoring status.
4.1.8 5TONE signaling
5Tone has 9 encoding formats: CCIR1, CCIR2, ZVEI1, ZVEI2,
ZVEI3, EEA, EIA, USER DEFINED1 and USER DEFINED2. The
last two formats are customized modes.
1. 5tone decoding
The decoding template is the 5tone decoding template. If the
decoding template is the same to that of encoding, the decoding will
be successful.
When the radio receives correct 5tone signaling, turning on
squelch according to the receiving squelch mode set by the user,
you can receive the call and the orange LED will flash.
After successful decoding, the radio will operate according to
the decoding call response set by the dealer.
2. 5tone encoding
The ending template is made of 1-3 encoding sequences. Each
encoding sequence can be set to 5tone or DTMF. If 5tone is
selected, you need to set its content.
If the PTT ID of the selected channel is set to 5Tone , 5Tone
will be transmitted when calling.
Or, when pressing the side key for Call1/2/3/4 , 5tone
signaling will be sent, this function is programmed by the dealer.
4.1.11 PC Programmable
You can program the radio functions and adjust some
parameters by PC programming software KSP7200.
4.1.12 Squelch Level Selection
The purpose of the squelch is to mute the speaker noise when
no signals are received or the signals are weak. When the squelch
is activated, you can hear noise from the speaker; when the
squelch is inactivated, you will not hear noise form the speaker.
Selecting the squelch level is to select which the signal strength
level is strong enough to enable the squelch or weak enough to
disable the squelch. Over high squelch level will make the radio
unable to receive signals efficiently when signals are weak; over low
squelch level will make the radio communication affected by noise
or other irrelevant signals. The squelch level has 0-9 options..
4.1.13 Beep Tone Volume
This setting controls the power on tone, channel busy tone and
TOT tone, etc..
4.2 Parameter Setting (PC Mode)
The radio parameters have been programmed in the factory.
The user can reset the radio parameters such as working frequency,
channels, CTCSS/DCS and auto scanning. We designed a user-
friendly and convenient programming software KSP7200 for users
to set parameters on the radio. The programming steps are as
follows:
a. Install the programming software KSP7200.
b. Connect the radio to the computer serial port with the
