18.1. Receiver RF IF Circuit
18.1.1.
Circuit Operation:
The signal of 46 MHz band (43.72 MHz~44.20 MHz) which is input from ANT is filtered by
DUP101, and is input to Pin 42of IC101.The RX VCO which oscillates at T201 and IC101 is locked
to 1st Local frequency by PLL inside IC101. (PLL is controlled by serial data output from Pin 28 ,
29 and 30 of IC901.)An input signal from Pin 42 of IC101 and 1st Local frequency output from RX
46
