Page 23: Circuit Description
TK-3170/3173 CIRCUIT DESCRIPTION crystal filter (XF701) to remove the adjacent channel signal. 1. Frequency Configuration The filtered first IF signal is amplified by the first IF amplifier The receiver utilizes double conversion. The first IF is (Q703) and then applied to the lF system IC (IC701). The IF 49.95MHz and the second IF is 450kHz.
Page 24 TK-3170/3173 CIRCUIT DESCRIPTION 2-5. Audio Amplifier Circuit IC13 IC12 (1/2) IC13 (2/2) The demodulated signal from IC701 is amplified by IC10, AQUA-L and goes to AF amplifier through IC13. The signal then goes through an volume control (IC16), and is routed to an audio power amplifier (IC18) where it is MMUTE amplified and output to the speaker.
