Just got my Kenwood SM-220 monitor scope hooked up and running to keep an
eye on my exciter and final signal quality.  Which display do I use, and
what do I look for to detect rf feedback in the signal without putting a
trashy signal on the air?  I know my TS-430S has a case of rf feedback, and
I'm working on that.  The thing I want to do is to be able to know that by
looking at the scope, therefore avoiding putting out a bad signal and having
someone tell me it's bad.  My rf plumbing from the transceiver and final run
through the back of the scope.

I assume the trapezoid would be the display of choice here.  If so, do I use
a one or two tone test, and what should I see if there is rf feedback?  Or,
is there another display/test for that purpose?  Would appreciate guidance
on this as it is my first exposure to using a monitor scope.
