RF and AF Gain

[Edward A. Dauer]

I believe there is another reason to reduce the RF gain with the AF above
what it otherwise would be; and I don¹t know that it has anything to do
with AGC or the evolution of detectors over time.  I have been doing it
for over a half century and I still do it with my KX3 on CW.  In casual
rag chews where the S/N ratio is robust, backing off the RF gain is
another way to get rid of externally-created noise relative to audio
output.  It just makes for more comfortable copy.  (I almost never do it
with the K3, since that rig is used almost exclusively for DX and contest
work, where comfort isn¹t an asset.)  Maybe it¹s a purely subjective
phenomenon, but it works for me.


Ted, KN1CBR

Funny Ted,
I am starting to use the RF gain more now in the last few months then ever before… Maybe just tired to listening to the noise floor, hi hi.
