CIRCUIT DESCRIPTION 1) Receiver 1. RX Method: Triple Super Heterodyne Method 1st IF. 248.45MHz 2nd IF. 38.85MHz 3rd IF. 450KHz 2. Front End 0.1 ~ 29.995MHz The signal input from antenna is switched at band switch D19, passing through the low pass filter, it is amplified at RF amplifier Q15. Then the signal is added to the 1st mixer IC3 through the band switch D17. - Page 4 The 2nd Mixer The input signal and the 2nd local signal is added or subtracted at mixer IC4, and switched to FM/AM receiving side or WFM receiving side at D24 or D25 . FM/AM At FM/AM receiving side, the crystal filter XF1 selects the signal of 38.85 MHz. The signal is amplified at the 1st IF amplifier Q22 after the adjacent signal is eliminated.
- Page 5 6. Audio FM/AM/WFM The audio output signal for receiving FM/WFM and AM is switched at IC9. The output audio signal is input to pin 1 of IC13 of stereo multiplex demodulator through AF amplifier IC17. When the input audio signal doesn't have a pilot signal, each audio signal is output from pin 9 and pin 10 to pin 1 and pin 16 of the audio amplifier IC14 equipped with the electronic volume.
- Page 6 vari-cap D15 and D16 to make the phases equal. In result the stabilized oscillation can be done at the desired frequency. The 2nd Local IC1 compares the frequency gained by dividing the signal added to pin 19 of IC1 by the control signal from IC7 with the frequency gained by dividing the reference frequency of 12.8 MHz inside IC1.
