[Elecraft] Noisy RX redux

[Don Wilhelm]

Mike,

The most important part of determining which AGC settings will work for 
you is in the statement that you should not be listening for the noise 
neither with a signal active, nor with no signal - you want to listen 
for the K3 audio response between breaks in the received signal.

To a certain extent, the AGC settings that you would prefer depend on 
your operating preferences.  A CW operator who is doing contesting or 
DXing would like to have a difference between strong signals and weak 
ones, while a ragchewer would probably prefer to have most of the 
signals at the same audio level.

73,
Don W3FPR
