RF amplifier is mixed with the first local oscillator signal from PLL frequency synthesizer in the first mixer Q23 to generate a 45 050MHz first IF signal The first IF signal is then fed through two monolithic crystal filters XF1 to remove spurious signals from adjacent channels 3 IF Amplifier The first IF signal is amplified in Q22 and then enters the IF processing chip IC1 The signal is mixed with the second local oscillator signal in IC1 to create a 455KHz second IF signal The second IF signal is then fed to a 455KHz ceramics filter CF1 to eliminate unwanted signals before it is amplified and detected in IC1 4 Audio Amplifier The demodulated audio signal obtained from IC1 is amplified in IC7 1 4 and then filtered by low pass filter Q19 and high pass filter Q20 and then de emphasized by R130 and C156 The resulting audio signal passes through a volume control circuit and then is amplified to a sufficient level to drive the speaker by audio power amplifier IC8 5 Squelch Part of the audio signal from IC1 re enters IC1 and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level The DC signal goes to the analog port of the microprocessor IC11 IC11 determines whether to output sounds from the speaker by detecting whether the input voltage is higher or lower than the preset value To output sounds from the speaker IC11 sends a high level sign
