Chapter 3 Electrocircuit
3.1 Frequency Configuration
Figure3.1 Frequency Configuration
This radio adopts the 2nd Mixer, the 1st IF 49.95MHz, the 2nd
IF 450kHz.
The receiver's first local oscillation is generated by the frequency synthesizer. The second local oscillation is generated by the crystal oscillator.
The transmitter signals are generated by frequency synthesizer.
The reference frequency of frequency synthesizer is generated by TCXO.
3.3 Receiver (RX)
IC5 inner circuit and X3 (49.5MHz) compose the 2nd local oscillator. The 2nd local oscillation (49.5MHz) and the 1st IF signal (49.95MHz) are mixed at IC5 to generate the 2nd IF 450MHz .
After the 2nd IF signal is amplified and its amplitude is limited at IC5, and then filtered at porcelain filter (CF1,450kHz), IC5 demodulates and sends out audio signals.
Figure 3.3IF System
Receiver Audio Signal Processing
IC6 and its peripheral circuit compose the receiver audio signal processing circuit. IC5 sends audio signals to IC6-C for amplification, and then to IC4 (CTCSS signaling filtering circuit) and IC6-D. After the signals are amplified, de-emphasized, filtered at IC6 and other cells, the HF (high frequency) and LF (low frequency) will be eliminated, and the remaining 300-3000Hz audio is sent to Q9 for amplification and then to volume potentiometer for adjustment and finally sent to the audio amplifier (Ic8).
Figure 3.2 Receiver Illustration
The Receiver Front Terminal
Signals from the antenna pass through the RX/TX switch (D1, D2, D4, D5); and then undesirable out-of-band signals will be filtered out at the band pass filter (BPF) consisting of C227, L8, L15, C70, C126, C218, L9, C217, L10, C127; then signals are amplified at the low noise amplifier (LNA) consisting of Q20 and its peripheral components.
The output from the LNA passes the BPF consisting of L5, L6, L7, C228, C124, and C132 for filtering and then is sent to the first grade frequency mixer (Q19).
MCU produces output voltages and alters the capacitance of the variable capacitor diodes D21, D22, D23, D24, D26, D30 to control the center frequency of the band-pass filter.
The First Frequency Mixer
After mixing the receiving signals and the first local oscillation signals from the frequency synthesizer, the 1st IF signals
49.95MHz are generated. The first IF signals pass the crystal filter (XF1, XF2) , which will filter the signals of adjacent channel and those out of band.
IF Circuit
The 1st IF signals from the crystal filter are amplified at the first IF amplifier (Q21), and then are sent to the IF processing IC (IC5, MC3361). The IF IC consists of the 2nd frequency mixer, the 2nd local oscillator, IF amplifier, limiter, phase frequency detector, and noise amplifier.
Figure 3.4 Receiver Audio Processing
Squelch Circuit
Demodulation output from IC5 is sent to the selection frequency noise amplifier, which consists of IC5 inner noise amplifier and C107, R124, R152, C33, and C35, to be filtered off the noise. After being amplified at Q7, noise is sent to D17 and D18 for wave checking and then sent to MCU, which determines the noise volume to control the squelch.
Audio Amplifier
IC8 and peripheral components construct the 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 control.
When AFCO is at the high level, Q37, Q8, Q33, and Q38 will be connected, and IC8 starts working and voice comes out from the speaker.
Q36: Receiving audio signal switch
Q35: Warning tone switch
Q25: Indication tone switch

PT4200 SERVICE MANUAL
CTCSS Signal Filtering
The IC5 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 IC4 can filter out the signals out of the CTCSS/DCS frequency spectrum to ensure MCU to decode CTCSS/DCS more precisely.
3.2 Transmitter (TX)
Transmitter Amplifier
Figure 3.5 Amplifier and Antenna Switch Diagram
The modulated signals from VCO are amplified at Q2, Q3, and Q12 and then are sent to Q11 for amplification. Q11 output power:
4.5W.
The Q11 and Q12 gate offset is controlled by APC circuit. Changing gate-offset voltage can control the transmitter output power conveniently.
APC (Auto Power Control)
Figure 3.6 APC Circuit
R167, R168, and R169 are the amplifier current checker; IC3A is the sample amplifier of the amplification current; IC3B is the power comparison amplifier.
If the transmitter output power is too big, the amplifier current will increase, IC3A output will mount, IC3B output voltage decrease, the offset voltage added to Q11 and Q12 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 IC3B to set the power.
Transmitter Audio Signal Processing
amplified, the amplitude of them is limited, and are filtered, they are sent to VCO together with CTCSS/DCS for modulation.
D13, D308, and Q24 constitute AGC circuit which decreases signal amplitude to avoid signal distortion when MIC signal is too big.
Q34 is the power switch of audio processing circuit. It supplies power to IC7 only when in transmitting and it is controlled by MCU.
J2 is the external MIC socket. When external MIC is used, the inner MIC will cut off automatically, but PTT will remain activated.
3.3 Frequency Synthesizer
Figure 3.8 Frequency Synthesizer
The radio adopts PLL (Phase Locked Loop) frequency synthesizer.
The frequency synthesizer consists of standard oscillator, voltage controlled oscillator (VCO), programmable frequency demultiplier, phase comparator, and low pass filter.
Q14, L30, C120, C88, C142, C180, D8, and D9 constitute RX VCO. D12 is the modulation circuit of VCO.
ICI (MB15E03) is PLL integrated circuit, including programmable reference frequency demultiplier, programmable swallowing frequency demultiplier, phase comparator, and charge pump.
R244, c193, R202, R40, C207, R141, C205, R2, and C204 construct the low pass filter.
The standard frequency is supplied by X4 (TCXO, 13MHz).
The standard frequency fromTCXO (Temperature Control Transistor Oscillator) are demultiplied by the programmable reference frequency demultiplier at IC1 to acquire 5kHz or 6.25kHz 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.

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 tome.
Q6: Power filter to supply more pure power to reduce the noise of the frequency synthesizer.
3.4 Voice Indication Circuit
The radio features voice indication, which is very useful at night or in the environment of dim light.
Page 6
IC15 is a voice memory chip which stores the voice indication of channels, and every time you change the channel, the speaker will sound voice annunciation of the current channel number. Press voice annunciation key will repeat the voice annunciation of the current channel number.
If the voice annunciation function has been set, press voice annunciation key in the stand by mode and the speaker will sound voice annunciation of the current channel number. If turn on the radio again with the voice annunciation key pressed, the voice type will be changed. Repeat turning on the radio with the voice annunciation key pressed, the voice type will change in the sequence Chinese Male--- English Male--- Chinese Female --­English Female ---- No Indication .
3.5 Power Supply
The radio is equipped with 7.4V, 1200mAh Li-Ion battery. The battery supplies power directly to the transmitter amplifier circuit (Q11, Q12) and the receiver amplifier (IC8). The power supply of other circuits is the regulated 5V power.

PT4200 SERVICE MANUAL
Memorizer E2PROM AT24C08
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 pin5) are filtered at R155, R156, C242, and C243, and then sent to VCO and TCXO for modulation.
CTCSS/DCS signals from the receiver are sent to MCU(pin1) 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 P56 output is sent to APC part 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.
39 groups of standard CTCSS frequency is available on the radio, see Table 3.1.
CTCSS signals generated by MCU pass the low pass filter consisting of RC to be filtered off the high frequency over 300Hz and then are sent to VCO for modulation.

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.

If you switch the channel to channel 1-15, the scanning function is inactivated.
4.1.2.1 Carrier Wave Control Scanning
If the radio scanning setting is carrier wave control scanning , switch the channel to channel 16 to set the radio in the scanning working mode.
Each channel can be set the scanning added/deleted function solely: if the setting is scanning added, the channel will be added in the scanning list; if the setting is scanning deleted, the channel will not be in the scanning list.
The radio starts scanning from channel 1 to 16 repeatedly in the consequence of the scanning list. If signals are detected on a channel ( if the channel is set with receiving signaling the carrier wave must match the signaling), the radio pauses on that channel and will restarts scanning 0.5~5 seconds (scanning delay time) after the signals disappear.
If you switch the channel to channel 1~15, scanning is inactivated.
4.1.2.2 Time Control Scanning
If the radio scanning setting is time control scanning , switch the channel to channel 16 to set the radio in the scanning working mode.
Each channel can be set canning added/deleted function solely: if the setting is scanning added, the channel will be added in the scanning list; if the setting is scanning deleted, the channel will not be in the scanning list.
The radio starts scanning from channel 1 to 16 repeatedly in the consequence of the scanning list. If signals are detected on a channel (if the channel is set with receiving signaling the carrier wave must match the signaling), the radio pauses on that channel and will restarts scanning 0.5~5 seconds (scanning delay time) after the signals disappear.
If you switch the channel to channel 1~15, scanning is inactivated.

4.1.2.3 Priority Channel
You can set one channel in the scanning list as the priority channel, which has the highest priority during scanning. The radio scans the first non-priority channel in the canning list and then scans the priority channel, the next non-priority channel in the scanning list, and then the priority channel again. It goes on scanning in such sequence.
4.1.2.4 Revert Channel
If you press PTT button when the radio is in scanning state, the radio will transmit on the revert channel , which has 6 types:
Selected channel: The first channel in the scanning list.
Selected channel + current channel: If the radio is in the state of scanning pause, it will transmit on the current communication channel. Otherwise it will transmit on the first channel in the scanning list.
Priority channel: The radio will always transmit on the priority channel set in the scanning list when pressing PTT.
Priority channel + current channel: If the radio is in the state of scanning pause, the radio will transmit on the current communication channel. Otherwise it will transmit on the priority channel in the scanning list.
Last called channel: The last channel that received signals.
Last called channel + current channel: If the radio is in the state of scanning pause, the radio will transmit on the current communication channel. Otherwise it will transmit on the last called channel.
The current communication channel is the channel on which the radio pauses in the 4 following situations:
1 When the radio receives signals and does not restart scanning, the radio will stay on the current channel.
2 The radio will stay on the current channel during 0.5~5 seconds (scanning delay time) after signals disappear.
3 The radio will stay on the current channel when pressing the PTT during scan.
4 After releasing the PTT to end transmitting, during the preset transmitting dwell time, the radio will stay on the current channel. After the preset transmitting dwell time 0.5~5 seconds, the radio will restart scanning again.
4.1.2.5 Retrace Period
If the priority channel has been set in the scanning list and retrace period is also set, when the radio receives signals on a non­priority channel and pauses scanning, it will retrace the priority channel in a certain period (0.3~5s). If signals are detected on the priority channel, it will stay on the priority channel; if no signal is detected on the priority channel, it returns to the original channel it stays on.
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.
4.1.5 Auto Power Saving
When no signals are being received or no operations are being
Page 10
PT4200 SERVICE MANUAL
conducted for over 10 seconds, the battery power saving will be activated. When it is receiving signals or in operating state, battery power saving is inactive.
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.
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 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.
4.1.9 PC Programmable
You can program the radio functions and adjust some parameters by PC programming software KSP20.
4.1.10 Wired Clone
The radio can transfer the stored data to another radio of the same mode by a specified cable.
4.1.11 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.
4.1.12 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 and convenient Chinese/English programming software KSP20 for users to set parameters on the radio. The programming steps are as follows:

Chapter 9 KBC-58L Charger
9.1 Charger Specifications
A) Idling Input Current: 30mA
B) Charging Terminal Maximum Idling Voltage: 8.8V
C) Constant current charging: 200 270mA
D) Maximum Charging Time: 7 hours
E) Maximum Charging Voltage Limit: 8.45 0.1V
9.2 Charging and Charging Indicator
A) When DC inputs power voltage 14~20V, the indicator lights yellow.
B) When the battery is inserted into the charger, the red and yellow indicator lights. (The battery power is lower than 8.1 0.1 V. ) (When the voltage is lower than 6.0V, the red indicator become light slowly after about 20 seconds.)
C) When the battery voltage is lower than 8.1 0.1 V, the charger charge the battery with constant current. (Charging current is 200 270mA. It needs 3~4 hours to charge a battery that has been discharged completely.)
D) When the battery voltage is higher than 8.1 0.1 V, the charging current will decrease gradually; when the battery voltage is
8.2 8.4V, the charging current will decrease quickly; when the battery voltage is 8.4 8.5V, the charging current will close to zero (then the charger begins constant voltage output) and charging stops. This course takes about 2~3 hours.
E) When the battery voltage is 8.2 8.4V, the red, yellow and green indicator lights. When the battery voltage is 8.3 8.5V, the red indicator becomes dime and the green and yellow indicator light.
LED red: Charging indication
LED yellow: Power indication
LED green: Charging completion
Note: After putting the battery pack that has been discharged completely into the charger, its red indicator needs about 1~2 minutes to turn light.
