Hello-
People that want a good AM receiver for 2 meters :
I have a bunch of GRR-23 units, they are FAA VHF AM receivers built
by ITT Aerospace. Very sensistive and has a sharp dual section tunable
cavity filter in the front end. Dual gate MOSFET RF amp, mixer. Has a 2N5109
post-mixer amp, followed by crystal filter and 4 stage 20.6 Mhz. IF amp.Unit
is single channel crystal control, has dual 600 ohm audio channels, squelch,
good AGC.
Anyway, I have a couple crystalled up on 144.400. There is a synthesizer
available that replaces the crystal osc. module, however it hits every 25
Khz. only, but 144.400 is one of the frequencies it will cover.
CUL, Byron WA5THJ
