[Elecraft] K3 and WSJT-X Split operation.

Fri Jun 29 20:45:18 EDT 2018

Agreed.  So to make it simpler for me, I keep the tones within the 1500 
to 2200 Hz window, which is very nearly flat and I don't have to adjust 
anything.  To go from 1500 to 500 Hz is a lower output of the audio 
(card most likely), requiring adjustment to compensate (to avoid hunting).

(I've set 'fake it' so we'll try that in hound mode).
