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.

When using DATA A or AFSK A, you are normally working from a waterfall
display, and the computer application software can work SPLIT. I do
not see the need to operate SPLIT using VFO A and VFO B, but someone
can enlighten me to why that is useful.
A different situation exists for those using FSK D, but I don't think
that is what is being discussed.

My K3S does this on all bands regardless of wheter it has been power
cycled. Pressing the tune button while split in data mode keys the
transmitter but produces no output. Do nothing else but cancel split
mode and pressing tune will then key the transmitter and produce normal
tune output. I thought it was a strange feature ...
