Well, I see what you are saying, but the offset is the problem. And.
intuitively I will assume that the TX follows the mode set on the VFO.
Anything else is just plain weird.

Hi Randy,
I notice here that when you changed TX from VFO A to B, you assumed
the TX mode would become the same as the SUB RX mode because it was
assigned to VFO B too. My first thought is of course it should. But
should it? With a normal split situation, I'd think you'd want it to
be the same as MAIN RX. Tricky. TX mode is set indirectly, and not
always as expected.

This IS a problem - consider this scenario (this is how it happened
to me...)
I was listening to 30 meter CW (Main Rcvr) and also listening to a 60
meter channel (USB) on the Subrcvr. A station I wanted to talk to
came on the 60 meter channel. I selected the TX to use VFO B. They
reported that I was well off frequency. I immediately signed and
investigated and found that when the Main rcvr/VFO A was set to a CW
mode, the transmitter set to use the B VFO for USB was not on
frequency during transmit only. During rcv it was on frequency.
What this means is that there is a "booby trap" if your modes between
the two vfo/rcvrs is different (even though you are not operating
split) that could cause you to transmit outside the band or in the
case of 60 meters, well off frequency - which is very bad.
I wasn't trying to operate split with two different modes. I was
listening on two different bands with different modes.
