PT6808 Service Manual 

 

amplified by IC4 (2/2). The output signal is filtered by IC13 high pass filter, low power filter; high 

power filter and frequency band eliminator and is de-emphasized. 

 

Then the signal passes through audio amplifier IC7 (2/2), volume controller (IC8) and audio 

switch (Q25 and Q24 is connected), and then is sent to audio power amplifier (IC23). The amplified 

signal is output by built-in speaker.   

   

4.3.5 Squelch circuit 

 

The output of IC12 passes through FM IF chip, and then passes through BPF. The noise output 

from IC12 is amplified by Q4, and is commuted to DC voltage similar to squelch level by D4. The 

DC voltage is sent to the analog port of CPU (IC19). IC12 generates DC voltage (RSSI) similar to 

the voltage input by IF amplifier. CPU reads RSSI through pin 93.   

 

IC19 compares the voltage input from pin91 and pin93 with the default value, and then decides 

whether to output the signal through the speaker. 

 

4.4 Principle of Transceiver (Tx)

 

4.4.1 Speaker amplifier   

The signal coming from the built-in speaker passes through mute switch (Q26).   

 

If the speaker does not match with the microphone, the voltage of MSW on the universal 

connector becomes high level, and the mute switch (Q26) is connected. If the speaker matches with 

the microphone, MSW connects with the GND wire in the speaker and microphone. Therefore, Q26 

is disconnected; the built-in microphone is mute, and only the external microphone input signal to 

the speaker amplifier of TX-RX circuit.   

 

The signal coming from the microphone passes through MIC mute switch (Q26 in TX is 

disconnected), and then passes through low pass filter (IC25:1/2), high pass filter, ALC circuit, low 

pass filter, high pass filter, amplitude limit circuit and pre-emphasis/IDC circuit of IC13 in turn. 

When DTMF is encoding, mute switch (Q13) is disconnected to mute the MIC input signal.   

 

The signal passes through digital/analog conversion IC8 to make the maximum deviation 

adjustment. Then the output signal comes to the summation amplifier consisted of by IC7 (1/2), and 

mixes with the low speed data receiving from CPU (IC19) and 9600bps data receiving from the port 

of optional circuit board.   

  The output signal coming from the summation amplifier passes through digital/analog 

conversion (IC8), and then comes to VCO to modulate.   

 

The other signal coming from the summation amplifier passes through digital/analog conversion 

(IC8) again to begin BAL adjustment, and then passes through the buffer amplifier (IC1 2/2), and
