Circuit Description. 5-1 Transmitter 1) MIC AMP Circuit Voice signal from the microphone are applied to microphone amplifier U303. U303 contains a low-pass filter that has a 6dB/oct response between 300Hz and 3kHz and eliminate above 3kHz. The pre-emphasized audio signal is applied to VR302 to adjust maximum frequency deviation.
E- TECH C o., Ltd 16/19 4) IF Circuit The first signals from Q102 are fed to the matched pair crystal filter FL101, then IF signals are amplified in Q103. And those signals are fed to U101 which is composed of the second local oscillator, second local oscillator, second mixer, limiter amplifier, quadrature detector and active filter circuit. The second local oscillator at 20.945MHz with X 101 and is fed to the second mixer with the first IF signals to convert into 455kHz second IF signals.

E- TECH C o., Ltd 18/19 6-2 Voltage Check 1) Set up the radio frequency to (136.025[Mhz]) then measure whether R/Tx voltage is over 0.8[v]. 2) Set up the radio frequency (173.975[Mhz]) then measure whether R/Tx voltage is under 5[v]. 3) When Un-Lock is display on LCD means defective goods. 6-3 Transmitter 1) At the frequency range of (146.025[MHz]), set up Tx mode then adjust frequency by using VR 301 at the level of ±150[Hz]. High power should be 3.8~5.5[W].
