Chapter 3 Electrocircuit

3.1 Frequency Configuration

Figure 3.3 Frequency Configuration

This radio adopts the 2nd Mixer, the 1st IF 51.65MHz, the 2nd IF
450kHz.
The receiver's first local oscillation is generated by the frequency
synthesizer. The second local oscillation adopts the 4th harmonic

51.2MHZ of TCXO.
The transmitter signals are generated by frequency synthesizer.
The reference frequency of frequency synthesizer is generated by
TCXO.

3.2 Receiver (RX)

PT5200 SERVICE MANUAL

IF Circuit

The 1st IF signals from the crystal filter are amplified at the first IF
amplifier (Q204), and then are sent to the IF processing IC (IC204,
TA31136FN).
The IF IC consists of the 2nd frequency mixer, the 2nd local
oscillator, IF amplifier, limiter, phase frequency detector, and noise
amplifier.
After amplifying TCXO (X301), the 4th harmonic 51.2MHz is made
as the signal source of the 2nd local oscillation. The 2nd oscillation
signal（51.2MHz）and the 1st IF signal（51.65MHz）are mixed at
IC204 to generate 2nd IF（ 450kHz） . After the 2nd IF signal is
amplified and its amplitude is limited at IC204, and then filtered at
porcelain filter (wide band CF201/ narrow band CF202， 450kHz),
IC204 demodulates and sends out audio signals.

Figure 3.5 IF System

Receiver Audio Signal Processing

IC404， IC405， IC407， and IC408 and their peripheral circuit
compose the receiver audio signal processing circuit. IC204 sends
audio signals to IC404 for amplification, and then one route goes to
IC405 (CTCSS signaling filtering circuit) for waveform shaping and
then to IC6-D; one route goes to IC408 where the signals are
amplified, de-emphasized, filtered and the HF (high frequency) and
LF (low frequency) will be eliminated, and then for the remaining
300-3000Hz audio, one route is sent to volume potentiometer for
adjustment and finally sent to the audio amplifier (IC401), and the
other one route passes IC407 (2-Tone/5-Tone filter ) to MCU.

Figure 3.4 Receiver (RX)

The Receiver Front Terminal

Signals from the antenna pass through the RX/TX switch (D102,
D103, D104); and then undesirable out-of-band signals will be
filtered out at the band pass filter (BPF) consisting of C260, L756,
L732, C259, C750,C731,D700,C730,L212,C256， C257， D210，
C255， L211，C253， and D209; then signals are amplified at the
low noise amplifier (LNA) consisting of Q26 and its peripheral
components.

The output from the LNA passes the BPF consisting of L207，
L206，L720， C248， C702， D207， C245， C244， and C733 for
filtering and then is sent to the first grade frequency mixer (Q21).

The First Frequency Mixer

After mixing the receiving signals from LNA with the first local
oscillation signals from the frequency synthesizer, the 1st IF signals
（ 51.65MHz） are generated. The first IF signals pass the crystal
filter (XF203), which will filter the signals of adjacent channel and
those out of band.

Figure 3.6 Receiver Audio Signal Processing

Squelch Circuit

Demodulation output from IC204 is sent to the selection frequency
noise amplifier, which consists of IC204 inner noise amplifier and
C121，R252，R211，C209，and R212 to be filtered off the noise.
After being amplified at Q205, noise is sent to D299 for wave
checking and then sent to MCU, which determines the noise
volume to control the squelch.

Audio Amplifier

IC401 and its peripheral components construct the BTL audio
amplifier.
Receiving audio signals, voice indication signals, indication tone
signals and warning tone signals are collected for audio
amplification to drive the speaker. Warning tone has no volume

Speaker Impedance: 16Ω
Q405: Receiving Audio Signal Switch
Notice: Any terminal of the speaker cannot be connected with the
ground!

CTCSS Signal Filtering

The IC204 demodulated output audio signals may contain CTCSS
(continuous tone coded squelch system) and DCS (digital coded
squelch). The frequency spectrum of CTCSS/DCS is 2-250Hz. The
filtering circuit constructed by IC405 can filter out the signals out of
the CTCSS/DCS frequency spectrum to ensure MCU to decode
CTCSS/DCS more precisely.

3.3 Transmitter (TX)

Transmitter Power Amplifier

Figure 3.7 Power Amplifier and Antenna Switch Diagram

The modulated RF signals from VCO are amplified at Q101, Q102,
and Q103 and then are sent to Q104 for amplification. Q104 output
power: 4.5W.
The Q103 and Q104 gate offset is controlled by APC circuit.
Changing gate-offset voltage can control the transmitter output
power conveniently.

transmitter output power will decrease. Vice versa, such can ensure
steady transmitter output power in different working circumstances.
MCU changes the input power to IC3B to set the power.

Transmitter Audio Signal Processing

Figure 3.9 Transmitter Audio Circuit

IC402 and IC408 and their peripherals components construct the
transmitter audio processing circuit. After the audio signals from
MIC are amplified, one route is sent for demodulation (VOX signals)
and then sent to MCU; the other one route passes AGG circuit to
IC408, where the amplitude of signals is limited, and signals are
filtered and amplified, and then are sent together with CTCSS/DCS
to VCO for modulation.
J2 is the external MIC socket. When the external MIC is in use, the
inner MIC will be cut off automatically, but inner PTT will remain
activated.

If the transmitter output power is too large, the amplifier current will
increase, IC101A output will mount, IC101B output voltage
decrease, the offset voltage added to Q103 and Q104 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 input power to IC101B to set the power.

The standard frequency is supplied by X301 (TCXO, 13MHz).
The standard frequency from TCXO (Temperature Control
Transistor Oscillator) are demultiplied by the programmable
reference frequency demultiplier at IC301 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 swallowing 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.
N=FVCO/FR
N： Frequency demultiplication times
FVCO：VCO oscillation frequency
FR： Reference frequency

Check Loss of Lock: When PLL is in loss of lock, IC pin14 sends out
low level signal to MCU, which controls the transmitter not to
transmit and initiate warning tome.

3.5 Voice Indication Circuit

The radio features voice indication, which is very useful at night or
in the environment of dim light.
MCU stores the voice indication of channels. If Channel
Annunciation function has been activated, every time you change
the channel, the speaker will sound voice annunciation of the
current channel number.

3.6 Power Supply

The radio is equipped with 7.4V, 1200mAh Li-Ion battery. The
battery supplies power directly to the transmitter amplifier circuit
(Q103, Q104) and the receiver amplifier (IC401). The power supply
of other circuits is the regulated 5V power.
IC502: 5V low voltage difference, micropower regulator, together
with Q10, and Q30 supply big current 5V power to the whole radio.
Q502: T5V switch, controlled by MCU.
T5V: Supplies power for the front terminal of the transmitter.
Q505: R5V switch, controlled by MCU.
R5V: Supplies power for the receiver RF amplification, mixing, IF
processing, audio signal processing.
Q503: C5V switch, controlled by MCU
C5V: The 5V power controlled by power saving supplies power for
the frequency synthesizer.

Memorizer （E PROM，AT24C64）

Memorizes the radio channel data, CTCSS/DCS data, and other
data of function setting and parameter adjustment.

CTCSS/DCS Encoding and Decoding

CTCSS/DCS signals generated by MCU (output form pin20 and
pin26, PWM wave) are filtered at the filter circuit and then sent to
VCO and TCXO for modulation.
CTCSS/DCS signals from the receiver are sent to MCU for
demodulation. MCU determines whether the signals contain the
same CTCSS/DCS as that set on the radio and decides whether to
turn on the speaker.

Power Adjustment

MCU PIN2 sends DC signals to APC to control the transmitter
output power.

CTCSS

CTCSS (continuous tone control squelch system) is a squelch
control system modulated on carrier wave with continuous subaudio
frequency as pilot frequency. If a channel is set with CTCSS, only
when both the CTCSS of the receiver and that of the transmitter are
identical, communication is available, which avoids interference of
other signals.

DCS

DCS (digital code squelch) is a kind of continuous digital code
modulated with voice signals on carrier wave to control squelch.
83 groups of standard codes (positive and inverse code) are
available. See table 3.2.
DCS signals generated by MCU (PWM wave shape) pass the low
pass filter to be filtered off the high frequency over 300Hz and then
are sent to VCO and TCXO for modulation. VCO modulates the
high frequency of DCS signals; TCXO modulates the low frequency
of DCS signals.
CTCSS/DCS signals from the receiver are sent to MCU for
modulation. MCU determines whether the DCS encoding of the
receiving signals is identical with that set on the radio and decides
whether to turn on the speaker.

Chapter 4 Function Description and Parameter
Setting

4.1 Major Functions

4.1.1 16 Channels

The radio stores 16 channels.

4.1.2 Scan Channel (programmable by PC software)

a) Press the key designated as “ Scan” to activate scanning.
While in scanning, the radio checks every channel and stops on the
channel on which a signal is detected until that signal disappears. If
the delay time between signal disappearing and continuing
scanning has been preset, the radio will remain on that channel in
the delay time even receiving any signals at that time.
Only when there are two channels added in the scan list and the
scan function has been activated, the radio can start scanning.

b) The dealer can set the revert channel (transmitting channel) in
scanning among the following options:

1) Selected: The radio always reverts to the channel selected
before scanning when pressing PTT.

2) Selected + Talk Back: When the radio is in scanning, press the
PTT button and the radio will transmit signals on the selected
channel.
When the radio is in scanning pause, press the PTT button and the
radio will transmit signals on the current talk back channel.

3)Priority: When pressing PTT, the radio will transmit signals on
the priority channel in the scanning list.

4) Priority + Talk Back: When the radio is in scanning, press the
PTT button and the radio will transmit signals on the priority
channel. When the radio is in scanning pause, press the PTT button
and the radio will transmit signals on the current talk back channel.

5) Last Called: When pressing PTT button, the radio will transmit
from the last channel that received a call. If it has never received
any calls, it will revert to the first channel in the scanning list.

6) Last Used: When pressing PTT button during the scanning, the
radio will transmit from the last channel that you used to transmit. If
it has never made any calls, it will revert to the first channel in the
scanning list

c) Priority Scan

During scanning, if the priority channel has been set on the radio,

8

when the priority channel receives a signal the radio will
automatically switch to the priority channel even the normal channel
is receiving signals at that time. And the radio will stay on the
priority channel till that signal disappears. The dealer can set the
delay time between signal disappearing and continuing scanning.

d) Temporarily Delete

When scanning pauses on a channel,channel, press and hold the
button programmed as “Temporarily Delete” or “Scan +
Temporarily Delete” for 1 second to delete this channel temporarily
from the scanning list.
Note: The priority channel cannot be deleted. And when the number
of scanning channels is less than 2, you cannot delete any channel,
either.
After exiting scanning mode and entering it again, the temporarily
deleted channel will be added in the scanning list again.

4.1.3 CTCSS/DCS

CTCSS/DCS can realize selective calls and group calls. On the
same channel, only the two parties whose CTCSS/DCS are
identical can communicate. CTCSS/DCS signaling code on the
channel is preset.

4.1.4 TOT

The purpose of the time-out timer is to prevent any single person
from overlong using a channel to transmit and affecting the whole
group communication.
If the radio transmits longer than the preset TOT time limit, the radio
will stop transmitting and warning tone sounds. To stop the warning
tone, release the PTT button. Press the PTT again you can resume
transmitting.

TOT Pre-Alert:

You can set the time when the radio generates a "Pre-Alert tone",
before the TOT (Time Out Timer) expires. TOT will expire when the
selected time passes after a “Pre-Alert Tone”.

TOT Rekey Time:

TOT Rekey-Time sets the "penalty" time in which the radio cannot
be re-keyed for transmitting after the Time Out Timer setting is
exceeded. During the Rekey time, if you press PTT, warning tone
sounds and transmission is prohibited.

TOT Reset Time:

TOT Reset Time sets the minimum "wait" time allowed between
transmissions that will reset the Time Out Timer. After setting this,
TOT continues even after PTT is released unless the TOT Reset
Timer has expired.

4.1.5 Auto Power Save

When no signals are being received or no operations are being
conducted for over 10 seconds, the battery power saving will be
activated to reduce power consumption. When it is receiving signals
or in operating state, battery power saving is inactive.
Power Save Type: 1:1, 1:2, 1:4, and OFF.

4.1.6 Low Battery 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. When the speaker sounds warning
tone, the radio will stop transmitting.

PT5200 SERVICE MANUAL

4.1.7 Monitor

When no signals are being received, the radio squelch circuit mutes
the speaker.
Press the MONI key to cut off the squelch control circuit, and you
will hear noise from speaker (no mater whether there are signals).
Such operation is very useful when you want to adjust voice volume
or receive weak signals (to avoid voice intermittence when in weak
signals).
When you press the MONI key, the green indicator lights, and the
radio is in the state of monitoring.

4.1.8 、 5-Tone Signaling

The dealer can activate or inactivate this function by programming.
5-Tone Signaling has 17 coding formats: CCIR1, CCIR2, PCCIR,
ZVEI1, ZVEI2, ZVEI3, PZVEI, DZVEI, PDZVEI, EEA, EURO
SIGNAL,NATEL, EIA, CCITT, MODAT, USER DEFINED1, and
USER DEFINED2. The last two are customized models.

1) 5-Tone Decoding
When receiving proper 5-tone signal, squelch will be activated
according to the “SP unmute” set by the user, and the radio can
receive the call and orange LED flashes.
The dealer can program the response way after decoding
succeeds.

2) 5-Tone Encoding:
If the PTT ID on the channel you select has been set with 5-Tone, 5­Tone signal will be transmitted when making a call.
Or transmit 5-Tone signal by pressing the PTT button and CALL1 or
CALL2 button, which can be set by the dealer.

4.1.9、 2-Tone Signaling

The dealer can activate or inactivate this function by programming.

1) 2-Tone Decoding
When receiving proper 2-Tone signal, squelch will be activated
according to the “SP unmute” set by the user, and the radio can
receive the call and orange LED flashes.
The dealer can program the response way after decoding
succeeds.

2) 2-Tone Encoding:
If the PTT ID on the channel you select has been set with 2-Tone, 2­Tone signal will be transmitted when making a call.
Or transmit 2-Tone signal by pressing the PTT button and CALL1 or
CALL2 button, which can be set by the dealer.

4.1.10、 PC Programmable

You can program the radio functions and adjust some parameters
by PC programming software KSP5200.

4.1.11、 Busy Channel Lockout

If “busy channel lockout” has been activated, transmitting signals
is prohibited on the busy channel. If you press the PTT to transmit
on the busy channel, the speaker will sound busy channel lockout
tone, and you cannot transmit signals.
The dealer can set one of the following BCL types:

1) OFF: BCL is inactive and you can transmit on the busy channel.

2) Carrier wave: If carrier wave is detected, the radio is unable to
transmit.

3) CTCSS/DCS: The radio is allowed to transmit when the
CTCSS/DCS signalings are identical.

4) Selective signaling: The radio is allowed to transmit when the

selective signalings (2-Tone or 5-Tone) are identical.

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

This option controls power on tone, channel busy tone and TOT
tone.

4.2 Parameter Setting (PC Mode)

The radio parameters have been programmed in the factory. The
user can program the radio parameters such as working frequency,
channels, CTCSS/DCS, auto scanning. We designed a user friendly
