The flex backend in hamlib which WSJT-X uses is just using the standard Kenwood
calls to set split.
All that does is the SP1 command which should simply turn on split
It also sets the freq and mode for VFOB using the standard kenwood commands.
It knows nothing of slices.
So it's really "assuming" your Flex is setup up as a simple rig with two VFOs
on one slice that can be controlled via the standard Kenwood commands.

Thanks for the replies everyone.
I’m trying to understand what WSJT-X is assuming about Flex 6xxx radios that
results in the odd behavior I described. WHY I want to operate split is
irrelevant to the question but just for information, I am trying to experiment
with different ways of using WSJT-X, mostly just to understand it. I’ve read
the documentation through and this aspect is not well covered. My experience
is use cases often follow (the suggestion regarding JA operation on 160 is
potentially a good example). Another is it appears to BE doing something that
doesn’t make sense and it may be helpful to report a bug but, again, that’s
irrelevant to my post.. All I’d like to know is if anybody actually KNOWS what
WSJT-X does or is trying to do in split mode when set to a Flex 6xxx radio.

Bill, Mike and others,
You do realize that JA on 160 meters is restricted to using FT8 at 1908 khz?
Practice has been for JA to call for DX at their allocation and listen for NA
stations transmitting at 1840. Widening the bandwidth window is not very
eloquent. Surely using a split VFO option with 2 slices would be more feasible.
My 2 cents…

Hi Jay,
I see no mention of top band in the OP, although there may be issues using
traditional split operating to work stations in a separate sub-band I don't
think that is related to the OP's query. Currently the use of SPLIT mode on a
rig by WSJT-X is incompatible with working stations on a separate sub-band as
SPLIT is used for a different purpose i.e. to extend Tx coverage up to the
bandwidth of the receiver and to ensure cleaner Tx signals free of unwanted
audio harmonics.
