[Elecraft] K3 and WSJT-X Split operation.

[Bob McGraw K4TAX]

If it power hunts, this is a clear indication that the audio level is 
not correct.  Be sure to set the level such that you have 4 bars solid 
on the ALC meter and the 5th bar flickering.   Now, with that said, this 
is not ALC, but is audio level.  For others to advise you and even the 
instructions in the software manuals, unless they have set up and 
operated an Elecraft radio, the topic of adjusting for no ALC is 
incorrect and thus DOES NOT apply to Elecraft radios.
