10. The signal is heterodyned again with a second local oscillator signal within 1 200 to create a 450kHz second IF signal The second IF signal is then fed through a 450kHz ceramic filter CF200 to further eliminate unwanted signals before it is amplified and FM detected in IC200 XF201 L71 0522 05 Nominal center frequency 38 850MHz Pass band width 5 0kHz or more at 40 stop band width 20 0kHz or less CF200 L72 0958 05 Nominal center frequency 450kHz band width 6 0kHz or more band width 12 5kHz or less 4 AF amplifier The recovered AF signal obtained from 1 200 is amplified by IC300 1 4 filtered by the 00 low pass filter 2 4 and IC300 high pass filter 3 4 4 4 and de emphasized by R303 and C306 The AF signal is then passed through a WIDE NARROW switch Q303 The processed AF signal passes through an AF volume control and is amplified to a sufficient level to drive a loud speaker by an AF power amplifier 1 302 1 3107 CIRCUIT DESCRIPTION 5 Squelch Part of the AF signal from the IC enters the FM IC again 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 from the FM IC goes to the analog port of the microprocessor 1 403 403 determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset valu
