Instead of doing that, why not simply hijack the VFO B display and
flash "TX TEST" when in test mode?

I know we're not supposed to post "ME TOO" comments, but this is a
great idea.  I would limit hijacking the VFO B display to ONLY when
actually "transmitting" (even though in TEST you are not really
transmitting).  While in RX, let the VFO B display just be the VFO B
"normal" display.

Yup...I REALLY REALLY REALLY like this idea.
