The audio derived AGC in the older T-T radios has always bugged me,
but I have never had much success in getting rid of the "pop".
Replacing the 4.7 mfd AGC electrolytic cap with a tantalum cap does
improve things. W3TS built a little MC1350 based, RF derived AGC
voltage generator for his Corsair II, but the one I built works like
many of my RF projects (either not at all or self oscillation).
I am experimenting with an Analog Devices SSM2165 compressor/limiter
just before the AF gain pot and it helps, but there is still a "peck"
on strong CW signals. I guess I should just live with it since my
ears are better protected, but it's irritating, like having a small
stone in my sock.
Does anyone else have any suggestions?
