Fredbox 2m AM mini-rig

There have been a few recent posts on the VHFam Yahoo group from people building versions of my Fredbox 2m AM rig. This rig was first designed back in the 1970s and rebuilt a couple of years ago.

Best DX worked was 160kms across the channel to Brittany from South Devon using just a whip antenna - not bad for 10mW. A proposal for a Fredbox 2 is shown in the files section of the VHFam group. This is a DSB version based on the NE/SE602 double balanced mixer.
