Howard:

I think I'll have to back the RF gain down on the TS480 at least somewhat in
order to effectively work with the noise bridge, based on my limited
experience with the device and my TS590.  Adjusting the RF gain on the 480
is, of course, a bit of a hassle, since you have to do it via the front
panel keypad and function knob, rather than a simple single knob adjustment,
but it is doable.  I seem to recall it is number 6, but will have to check
the manual.

In any case, I'm not going to go out into the RV today and try it, since
temps are in the single digits, wind chills are below 0, and since I'd have
to trudge through at least 12 inches of snow to get there.  (grin)

Tom, you got it right!
The minimum pulse is very accurate.  Any additional circuitry adds loss.
I am not sure if you can just attenuate the signal while listening on the
480, or if you will have to crank the rf gain back as well.
