2m AM rig

Many years ago I used a homebrew 2m AM rig. It was about 500mW out from memory. When I bought a second-hand Liner-2 SSB rig it was abandoned. I think it was scrapped for parts. I think the meter is still being used today as part of an antenna current meter on 630m! I can see an old Pye Telecom PF2AMB speaker/mic.

For several months I had a regular sked on CW with G5UM who was about 80km away. As I recall I used an external 455kHz "gimmick" BFO to resolve him. On RX the oscillator drifted! On AM it mattered little. He always gave me 559.

The rig was crystal controlled on TX.  It had a metal case covered in wood effect fablon. For its time, it was a decent rig and got me to France in a lift. Happy days!
