[Elecraft] RF gain/AGC issue

[Dave - AB7E]

What were your various AGC settings?  Also, what bandwidth were you using?

I just performed an experiment on 40 and 20 meters.

I found a CW signal.

I turned the AF gain all the way up, and the RF gain all the way down.

Then, I turned the RF gain up slowly, with AGC on, and then AGC off.

With AGC off, as the RF gain was advanced, I heard the signal well in
advance of hearing the noise.

With the AGC on, as the RF gain was advance, I heard the noise well in
advance of hearing the signal.

I repeated this test on many signals, with the same results.
