2.2 Licenses

It is requested by rules that each radio installation site (for

mobile station or base station) should be provided with a license.

The license carrier should guarantee that the Tx power, frequency

and deviation comply with the license requirements.

Transmission adjustment can only be conducted by

license-authorized technicians. Installation or operation of the

radio does not need a license.

2.3 Check before Installation

Every radio has been adjusted and checked before shipment.

Before installation, it’s better to check if the radio’s

transmission and receiving are normal to make sure its proper

operation.

The test should be performed with all cables and accessories

correctly connected.

Tx frequency, deviation, and power output should be checked,

as should Rx sensitivity, squelch, audio output, and signaling

operation.

2.4 Installation

1) Preparation

Check the vehicle and decide how and where to install the

radio antenna and accessories. Make sure that the cable will not

be extruded. And pay attention to the heat dissipation of the radio

to avoid overheating.

2) Antenna

The best position for the antenna is in the center of an open

and flat conduction region, usually the center of the vehicle roof

or the cover of the luggage trunk. Connect one end of the earth

wire to the cover of the luggage trunk and the other end to the car

outer shell so that the cover of the luggage trunk is grounded.

3) Connection of Power Cable

* First of all, please check whether there is a hole for the power

cable on the insulating board. If no, please bore the board with a

suitable drill bit and fix a rubber grommet on it to protect the

cable from abrasion.

* Afterwards, please pass the cable through the insulating board

and lead from the car into the engine room. Connect the red

conductor to the positive terminal of the accumulator and the

black conductor to the negative terminal.

* At last, ring the remained conductor and fix it.

Note: Please guarantee sufficient relaxation of the power
cable in the car so that the radio can be conveniently
disassembled, assembled, and repaired in the state of power
connection.

4) Installation

Warning: For passenger safety, please install the radio
securely using the supplied mounting bracket so that the
radio will not be loosened in case of collision.

* Take the mounting bracket as the sample to draw the position of

the four holes for screws. Then drill the holes on the instrument

panel, and then install the mounting bracket with 4 M5*16

self-tapping screws. (Note: Please install the radio at a position

convenient for operation, and leave enough space for connection

of the cable.)

* Slide the radio into the mounting bracket and fix it to the

bracket with 4 M4*10 SEMS screws (with flat washer and spring

washer). (Set an appropriate height and angle for the radio by

using different screw holes of the bracket.)

* Connect the antenna and the power cable to the radio.

* Install the microphone hanger at an appropriate position using 2

M4*16 self-tapping screws. (It should be made sure that the

microphone and its cable will not affect safe driving.)

* Connect the microphone to the MIC jack on the front panel of

the radio and put the microphone on the hanger.

Front end

The signal coming from the antenna passes through the

RX/TX switch circuit (D3 and D37), and passes through a BPF

consists of two LCs to remove unwanted out-of-band signals, and

then is routed to the low noise amplifier (LNA) consists of Q18

and its peripheral components where it is amplified.

Output signal from the LNA passes through a BPF consists of

three LCs to further remove unwanted out-of-band signal, and

then goes to the first mixer (Q19).

AGC circuit

AGC circuit, which consists of Q16 and its peripheral circuit,

will work to reduce the gain of Q18 only when the input signal is

too large.

First mixer

The Rx signal from LNA is mixed with the first local

oscillator signal from the frequency synthesizer to produce the

first IF signal (49.95MHz).

IF circuit

The first IF signal passes through the crystal filter (XF1) to

remove the adjacent channel signal and signal outside the

adjacent channel. Then the filtered signal is amplified by the first

IF amplifier (Q20), and is sent to the IF processing IC (IC6,

TA31136).

IF IC consists of the second mixer, IF amplifier, limiter,

discriminator, noise amplifier, and audio low pass filter.

Signal (16.8MHz) from X1 is multiple-amplified by Q11 and

its peripheral circuit to produce the second local oscillator signal.

Then the second local oscillator signal (50.4MHz) is mixed with

the first IF signal (49.95MHz) in IC6 to generate the second IF

signal (450kHz). And then the second IF signal is amplified and

limited in IC6, filtered by its ceramic filter (CF1 or CF2,

450kHz), and then demodulated in IC6. After that, the

demodulated signal is routed to the audio circuit to output audio

signal.

The selection circuit of the second IF filter consists of CF1,

CF2, D20, D21, and the peripheral circuit. When the mobile radio

is set to wideband, CF2 is put through and takes effect, while

4

PT8100 Service Manual

CF1 is cut off; when the mobile radio is set to narrowband, CF1

is put through and takes effect, while CF2 is cut off.

Squelch circuit

The demodulated signal from IC6 is sent to the internal noise

amplifier in IC6. Then the resulting signal is further amplified in

Q21 and demodulated in D25, and then the resulting DC level is

sent to the MCU squelch control circuit. This voltage is in inverse

proportion to the input signal.

The modulated RF signal from VCO is amplified by Q1, Q2,

Q4, and Q5, and is sent to IC1 for power amplification. Output

power of IC1: 25W.

Grid bias of IC1 is controlled by the APC circuit. Through

changing the grid bias voltage, the Tx output power can be

controlled conveniently.

APC（Automatic Power Control）circuit

D9 and D10 are RF detector diodes. The output power of the

RF amplifier is detected by RF detector diodes and converted into

DC level. Then the DC level is compared with the signal from

MCU and amplified in IC4, and is sent to grid in IC1 to control

the power output.

If the Tx output power is too high, the voltage detected by the

detector diodes will increase; IC4 output voltage will decrease, so

the bias voltage imposed on IC1 will also decrease, which causes

the Tx output power to be lowered, and vice versa. Thus, the Tx

output power can keep stable under different working conditions.

MCU can set the power through changing the voltage input to

IC4.

VCO OUT

The frequency synthesizer consists of reference oscillator,

voltage control oscillator (VCO), programmable divider, phase

comparator, and low pass filter (LPF).

Tx VCO unit consists of Q6, D1, D4, D5, and D6. D8 is the

modulation circuit of Tx VCO.

Rx VCO unit consists of Q12, D14, D16, D17 and D18.

IC3 (MB15E03SL) is the PLL integrated circuit, which

consists of programmable reference divider, programmable

divider, phase comparator, and charge pump.

The low pass filter consists of R54 and C113.

The reference frequency is provided by X1 (TCXO,

16.8MHz).

Reference frequency from TCXO (Temperature-Controlled

Crystal Oscillator) is divided by the programmable reference

divider in IC3 to produce reference frequency of 5kHz or

6.25kHz (determined by the preset channel frequency and is

controlled by MCU).

The oscillation frequency from VCO goes to IC3 where it is

divided by the programmable divider and is then compared with

the reference frequency to obtain the error signal. The signal is

then filtered by a low pass filter and is sent to VCO to change the

oscillation frequency of the VCO, enabling the frequency to

reach the set value. Then the VCO is locked.

Unlock detection: When PLL is unlocked, pin14 of IC3 will

output low level signal to MCU. Then MCU prohibits the Tx

from transmitting and makes an alert tone.

4.5 Audio Processing Circuit

Figure 4.5 Audio Processing

MIC signal processing:

Voice signal from MIC is sent to IC13A for amplification

(IC13A, D32, Q32 and other components form the AGC circuit to

improve the dynamic range of the circuit). Then the resulting

signal is pre-emphasized by C322 and R267 and goes to the IDC

circuit consists of IC13B. After being limited, the signal is

switched into wideband or narrowband in Q30 and then passes

through the low pass circuit consists of IC13C and IC13D to

remove signals above 3000Hz. Then the filtered signal is sent to

VR2 to adjust the deviation and modulated by D8, and then is

5

PT8100 Service Manual

sent to Tx VCO.

Rx audio signal processing:

Voice signal from IC6 is divided into two parts. One branch

of the signal is routed to the low pass circuit consists of IC8,

where it is amplified and filtered (to remove the voice signal) to

obtain more purified CTCSS/DCS signal, which is then sent to

MCU for processing. The other branch of the signal goes to IC9.

After being amplified by IC9C (Q29 is the gain switching circuit

which is used to switch volume between wideband and

narrowband), the signal is divided into two branches again. One

branch is sent to the 2-tone (5-tone) shaping circuit consists of

Q8, Q52 and IC10, where it is shaped into better square wave

signal, and then is sent to MCU to judge the 2-tone (5-tone)

signal; the other branch passes through the high pass circuit

consists of IC9D to remove the sub-audio signal and passes

through the de-emphasis circuit consists of R173 and C245. Then

the de-emphasized signal is passed through the low pass circuit

consists of IC9A and IC9B and the high pass circuit consists of

Q26. After that, the resulting signal goes to the volume switch

where the signal volume will be adjusted. After being amplified

in IC7, the signal will be output to drive the speaker.

Impedance of the speaker: 16

Note:

* None of the terminals of the speaker should be grounded.

* The emergency alarm sound has no volume limit.

4.6 Power Supply:

The radio uses 13.8V battery, and the Tx power amplification

circuit (IC1) and Rx audio power amplifier (IC7) directly adopt

the battery for power supply.

IC17: 3V, LDO, micropower regulator, which supplies power for

MCU, DTMF decoding unit etc.

IC16: 8V, LDO, micropower regulator.

Q38: 8T switch, which is controlled by MCU.

8T: Supplies power for front end of transmitter.

Q40: 8R switch, which is controlled by MCU.

8R: Supplies power for RF amplifier and mixer of the receiver.

PROM, A T24C512)

The memory is stored with channel data, CTCSS/DCS data,

other data for function setting, and parameter adjusting data.

CTCSS/DCS signal encoding and decoding:

CTCSS/DCS signal (output from pin97, PWM wave)

generated by MCU is sent to TCXO for modulation; and the

CTCSS/DCS signal (output from pin98, PWM wave) is sent to

VCO modulation.

CTCSS/DCS signal from the receiver is sent to MCU for

decoding. MCU checks if the CTCSS/DCS signal in the receiving

signal matches the preset value of the radio, and determines

whether to open the speaker or not.

CTCSS

CTCSS (Continuous Tone Control Squelch System) is a

squelch control system which is modulated on carrier and is

guided by a continuous sub-audio signal. 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.

PT8100 has 39 groups of standard CTCSS frequencies for

your selection. See Table 4.1.

CTCSS signal (PWM wave) is generated by MCU, and is

passed through low pass filter consists of RC to remove the high

frequency components (above 300Hz). Then the resulting signal

is routed to VCO for modulation.

DCS

DCS (Digital Code Squelch), which is used to control squelch,

is a series of continuous digital codes modulated on carrier

together with voice signal. If DCS is set, the speaker can be

opened only when the radio receives signal with the same DCS to

avoid disturbance of unwanted signals.

PT8100 has 83 standard codes (inverted and non-inverted) for

your selection. See Table 4.2.

DCS signal (PWM wave) is produced by MCU. It passes

through the low pass filter consists of RC to remove the high

frequency components (above 300Hz). Then the resulting 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 routed 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.
