Good morning/afternoon, Bill.
Don’t think anything is going wrong. Clearly, it’s working the way
it’s written.
My concern is that, in a crowded band situation, as stations spread
out, having the software automatically “split” TX and RX in the name
of spectral purity could lead to unintended interference to stations
operating perhaps several hundred Hertz away. In an environment where
there’s only one QSO in progress, this is pretty much a non-issue, but
when the passband fills, working with non-identical TX and RX tones
might lead to an effective 2-times congestion.
Practice appears to be in most circles (particularly on HF) for both
stations to use the same DF. That seems to be what most people expect.
Calling off DF can lead to click-chasing where stations ping each
other around the passband, leading to even more confusion.
Again, not saying this is the fault of the software, and keeping the
tones clean and well-centered is a good thing. Just don’t think it
will work well for the average operator under normal circumstances.
I’d vote for the software not to automatically make changes to
operator settings like DF, etc.
Thanks for all the amazing work you guys are doing….

Hi George,
one of us is misunderstanding the situation. There is no "split" of the
on-air signals, stations using split are transmitting exactly where the
red cursor is placed on the waterfall which is exactly the rig's dial
frequency plus the Rx DF.
