22. Thus the microprocessor blocks output from the audio amplifier and silences the receiver while no signal is be ing received and during transmission as well 4 Transmit Signal Path The speech input from the microphone MC1001 passes through the audio amplifier Q1027 NJM12902V which is adjusted the microphone gain The speech signal pass es through pre emphasis circuit to Q1027 NJM12902V which contains the IDC and low pass filter Then passes through VR1004 which allows manual adjustment of the transmitter deviation level The filtered audio signal is applied to varactor diode D1006 HVC306B which frequency modulates the VCO 01006 2565006 modulated signal from 01006 25C5006 15 buffered by 01004 25C5006 The low level transmit sig nal is then passes through the switching diode 01018 DAN235E to the buffer amplifier Q1018 25 5226 driver amplifier 01013 RQA0004PXDQS then ampli transmit signal is applied to the final amplifier 01012 RQA0011DNS up to 5 0 watts output power The transmit signal then passes through the antenna switch D1003 RLS135 and is low pass filtered to sup press harmonic spurious radiation before delivery to the antenna Circuit Description 4 1 Automatic Transmit Power Control Current from the final amplifier is sampled by C1012 amp C1020 and R1006 amp R1010 and is rectified by D1002 715 The resulting DC is fed back through 01014 LM2
