[Elecraft] Attenuator and RF Gain Settings

[Lance Wilson]

Don,

Given how you have set up your K3 I am in agreement with the performance
you've noted. I'm experimenting on 20M, RF gain full on, preamp and att off.
I am also listening under SSB conditions. I have the RF gain fully on only
to experiment with the AGC.

Here is an example, with the AGC off my noise level on the S-meter is S2 to
S3. With the AGC on it is S6 to S7 with no signal present. If I listen to a
S8 signal with the AGC on my noise level is still S6. With AGC off that same
signal is S7 with a noise level again of S2 to S3. This is not normal AGC
behavior and perhaps there are some issues between the DSP and hardware AGC.
Changing AGC parameters has no effect on what I am seeing.

Lance, NR7N
