[Elecraft] K3S audio board for K3 upgrade?

[Barry N1EU]

I agree with Vic - I want minimal AGC action, only kicking in on the
strongest signals to keep the audio level below the ear's attenuation
reflex (see http://n1eu.com/K3NA_rx_audio.pdf )

I have my threshold set at 14 (along with AF Gain at approx 9 o'clock and
RF Gain adjusted so I can just hear band noise).  (btw, you might try
mysettings if you ever experience pileup mush when on the receiving end of
packet pileups).

73, Barry N1EU
