CF XF1 and unwanted signal components are eliminated The resulting signal is amplified by the IF amplifier Q26 and goes to the FM IC IC5 The FM IC heterodowns it to the second IF of 450 kHz In FM mode the signal passes through a 12 0kHz external ceramic filter CF3 and goes to the FM IC The signal amplified by the internal IF amplifier is demodulated by the quadrature FM demodulation circuit using a coil L19 and converted into an audio signal and output In AM mode the signal passes through a 4kHz external ceramic filter CF1 and goes back to the FM IC It is amplified by the AM AGC amplifier built in the FM IC an audio output from the FM IC as an audio signal 2 1 4 AM bar antenna receiver circuit This unit incorporates an AM bar antenna and either the bar antenna or the supplied antenna can be selected in the 520kHz 1 8MHz SW and 3 5MHz 10 1MHz MW bands the initial value bar antenna The bar antenna has two kinds of tuners for SW and MW tuning one of which is selected with a switching FET Q32 Q48 Q52 The antenna is tuned with a varicap D60 for AM tuning to select a desired signal The signal from the bar antenna is amplified by and its impedance is converted by the buffer amplifier Q59 and the resulting signal goes to the common mixer Q28 for the B band The signal is routed over the same path for AM demodulation as for the supplied antenna after leaving the mixer 19 05MHZ FINE2 D20 24 KV1566J TUNE
