The difference of opinion in this thread is mostly about different

Fred,
In CQPWIN, I did work out a way to measure the precise length of each

they are of differing lengths. If any logging software types are curious,

Yep. I did it in ARRL SS Phone with N1MM. You just have to set a

Dave,
You can *effectively* increase the AGC threshold by 10 dB very quickly -
just turn on the attenuator.
Actually, that is more effective than reducing the RF Gain because it

Need threshold higher than 8, and Slope with a number less than

With such settings, AGC would be used for hardware protection and
hearing protection only. The linear part of the curve would be

Are there engineering reasons why the AGC threshold level can be set no
