My 2400-serial number K3 has begun to have a sporadic receive problem,
which has gotten much worse recently. It's really weird.
What happens is this - the receiver sporadically loses most of its audio
output level, until I move the AF pot a couple of degrees either way, at
which point it immediately restores the audio. Often, but not always,
this occurs right after a transmission (on CW), so I was initially
suspecting a failing relay, but the way it responds to a minute change
in the AF level setting makes me think something subtler. Any ideas?
