At time signal will mix with second root flap, switch to second IF signal. Through 450K filter, except that all disturb signals will be unchained, then be blew up and inspected. Audio frequency amplifier The audio frequency signal comes from inspected filter and be aggravated, then input to MCU(U811), then through adjust potentiometer, blow up by U460, get the audio frequency power, contact with MIC via T463. Squelch circuit and signal intensity list Check by U261: Output yawp signal, then put it into CPU (U811) and deal with it by the 25 feet interior. According to the electricity level signal which MCU get, one side, it can control SP MUTE, APX and AFC, to complete to control audio frequency output circuit (The level of CPU inside control system is from 1 to 9 grades, it can program by software or by keyboard). On the other side, it can control the signal strong list of LCD screen.

3. Transmit system (1). Speaker amplifier As show in Chart 4, audio frequency signal comes from MIC will be aggravated, then limited blow up by U411-A, all distortion audio frequency signals will be unchained by adjacent filter which makes up with U411-B caused by limited blow up. Modulate circuit The signal comes from speaker amplifier modulated by adjust potentiometer VR382, then modulating changeable reactance by varactors tube D348.

As shown in Chart 5. Output transmit signal will pass transmit and/or receive switch circuit and low-pass,

then send to antenna. Transmit and/or receive circuit has made up of D146 D145 D216. Start during

transmitting and stop during receiving, switch transmitting system and receiving system.

Auto power control circuit APC, use for get a reliable transmit power and transmit control output. This circuit

check out power discreteness end terminal current exhaust and control transmit output. Two reference

voltage from U170, one is give birth to the voltage which use for adjust the power output(AD1 give birth to ),

the other one is get the R171-R173 two terminal and end terminal exhaust current be direct ratio check out

voltage. On the output terminal of U181 can get a reference voltage and check out voltage dispersion be

direct ratio voltage signal. This signal by reverse then as APC voltage. This voltage be use control power

discreteness’ power control feet and make transmit output level off.

Circuit Description

5. PLL Circuit (1) PLL 19.25MHz reference oscillator output through PLL IC(U311) reference frequency then bring 5KHz and 6.5

KHz reference frequency. VCO output signal blew up by T337, then bring compare frequency by U311 dispart frequency. Use different dispart frequency ratio by CR311, and get different inspect posture consult frequency. According referenced frequency and comparable frequency value, then bring 5, 6.25, 10, 12.5 and 25KHz for step frequency value of PLL synthesizer. According referenced frequency and comparable frequency discrepancy value, the output correspond pulse voltage from the fifth feet of U311, change it to direct current signal direct current signal by filter after through Charge Pump, then bring lock voltage. (2) VCO Goal frequency is make up of FETT355 and T350 directly produced by Rapids oscillator. Lock controllable

voltage and then modify oscillator frequency by D353, D352, D346 and D345. (3) Lose lock detection circuit When PLL is on lose lock, one pulse will be plastic by R312 D312 C312 and R313, then add to LD side of

PLL (tenth LD side), and the voltage of LD side will be rose, CPU will control transmitting and receiving by

detecting the voltage of LD side. (4) Digital control circuit Conformation of Keyboard circuit: Directly input the signal come From the keyboard to CPU (U811).
