The more I test things, the pot doesn't work correctly when I feed the AF from the gen into the radio's audio/amp section. Basically for lower 3/4 of the volume knob I really don't hear anything until I get to the upper 1/4 of the pot.
But if I use the RF signal from the radio into the pot, and feed the signal to my tracer, the pot controls the volume all the way through like it should. So maybe the audio section is t clear after all.
I can also faintly hear the station I have tuned out of the radio speaker, even though nothing is feeding the audio section. Have to put your ear right up to it, but you can hear it. Not sure if it's just picking it up inductively, or if that's tied to my problem.
