[Elecraft] AGC Setting for PSK-31

[Julian, G4ILO]

I recently purchased an SB Live 24 card to use for datamodes, so I could use
the built-in Realtek sound for normal computer purposes. I can honestly say
I have not noticed any difference either on TX or RX in ordinary sound card
operation. I imagine there might be a benefit if I was using it with an SDR
(SoftRock, etc.) but I haven't tried that.

Although the K3's receiver may have the dynamic range to handle working with
the AGC off I think you would increase the risk of clipping or distortion
somewhere in the audio path that would result in "ghost" signals. I prefer
to operate with AGC on and use the filtering to exclude other signals that
would affect the AGC to the detriment of the one I am trying to copy.
