AWA Carphone FM Transceiver 70-85 MHz

IF 2.0 MHz, Rx = ( crystal * 5) - 2 MHz , 10.905Mhz for 52.525 Mhz, 1st IF 12.9 MHz

Tx = crystal x 24, 2.188 Mhz for 52.525

Orig: xtal = (Rx - 2Mhz) / 7, 10.3 to 13.2 Mhz

Orig: Tx = xtal x 36

As I remember from 1974 my MR10C, (16MHz x 9) +2 => 146.000 MHz Ch B
and I reground an FT243 crystal to 4055.555 for Tx
