It's nice to see some recognition that the issue is not the same for
people using two receivers as for people using a single receiver, but I
am not sure how well the proposed solution will actually work in the
two-receiver "sub-RX implied split" (or "reverse split") situation.
When I am using "sub-RX implied split", the K3's SPLIT indicator is off,
because I am transmitting on VFO A. The proposed solution would show
"NON.SPLT" on the VFO B display, which is not correct in this situation
(I am actually operating split, listening on VFO B and transmitting on
VFO A). If I manage somehow to leave my K3 in SPLIT mode with the DX in
the subRX, I will be transmitting on the DX frequency but the VFO A
display will show "SPLIT" even though in this case I am erroneously
operating non-split.
I also operate SO2V in many contests, meaning that I have two logging
windows open in my contest software, one for each VFO. If I choose to
work someone non-split from the VFO B logging window, the software
automatically puts the K3 into SPLIT mode in order to transmit on VFO B.
The VFO A display would show "SPLIT" while I am transmitting, but
actually I am not operating split.
The real problem is that the rig cannot read my mind. It has no way of
knowing whether I am listening to the other station on the main RX or
the subRX, hence whether I am actually operating split or non-split. My
solution to this is to ignore the K3's display and never use the SPLIT
button on the radio, i.e. to do all split- or VFO B-related operations
from software. The software knows my intention because it gives me a way
to tell it what I want to do, whereas until someone comes up with a
mind-reading module, the radio cannot know my real intention.

This method also works whether you're doing "real" split (RX on VFO A, TX on
VFO B) \
