Oh, there's no doubt it is a matter of personal preference. Still, SWR
is kind of meaningless when you are trying to check out changes to a
PA. Forward power is the meaningful measurement in that case.
I use CW, SSB, and JT65. I don't see where the mode has much to do with
whether SWR is a meaningful measure to see or not. What most people see
on an SWR meter is a *reverse* power measurement even if it is
calibrated in "SWR". Even with a dual-movement meter you adjust
your tuner for least reverse power, not for maximum forward power.
For a rig with no power control, forward power is going to be whatever
you have set RV1 to provide.
If the nano had unlimited resources to offer, this discussion wouldn't
happen. But it does have limited resources. If having to calculate SWR
and do near-real time measurements to do the calculation is a
requirement then at some point something else is going to wind up
getting cut.
My preference would be to cut SWR first.

I would say that is a matter of personal taste and preference Tim.
Some people just want reflected power or a blinking led. Others will
want to see meaningful numbers to compare with others when they make
mods to the PA chain. There are people that use the uBITx here just
on CW. Some just on SSB. Do you have a preference for that as well?
