SPLIT works in Diversity like it does with a single RX. Press SPLIT, and
hold REV while you set your TX frequency, release REV and you are back on
the DX frequency. I also LOCK VFOA so I don't lose the DX if I accidentally
bump a knob. I operated for years with a TS-930S and learned to press REV
while tuning the pileup with my left hand (index finger on TF-SET in TS-930
nomenclature and pinky on the VFO).
I'm in Diversity 99.9% of the time but set up a macro to be able to quickly
switch from Diversity mode to split pileup mode with the RXs separated (on
the pileup and DX frequencies). K6KR documented this in his K3 Utility
examples of macros. There is also a macro to go back into Diversity from
Dual RX split mode. As you discovered manually, the macro must first exit
SUB and then enter Diversity. I only need to go into split pileup mode for
truly massive pileups spread over many kHz. If it's a smaller pileup, I
just stay in Diversity-Split and use REV to find the station the DX is
working.
