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.
