[Elecraft] No Tune Power Output While Split in Data Mode

[Michael Eberle]

Don,

WSJT-X has a feature that uses SPLIT to keep the audio frequencies in a 
more usable range.  For example if someone is calling CQ at 300 Hz on 
the waterfall, instead of trying to transmit a 300Hz audio tone, WSJT-X 
will tune VFO-B down 1 KHz, enable SPLIT, and transmit a 1300 Hz tone.  
I find that this keeps me from having to re-adjust the audio levels when 
operating near either end of the waterfall. Working SPLIT like this 
keeps your TX audio between 1500 and 2000 Hz.
