That was my thought, as well, Dave.... but as a retired engineer that was
dormant in amateur radio for over 20 years before "coming alive" again in
retirement and as an engineer that got shoved into paperwork during the
last 13 years of my career, I've lost the "edge" I once had (if I had it!).

It seems though, that if I could cause the sweep to vary within reason for
audio presentation and then get the vertical to respond to detected RF,
I would have what I want.  Is that reasonable?  I'm asking because I am
no longer competent in those matters.
