Lou:

Both the TS590 and TS480 have an AGC function that is very easy to control,
and I've already played around with that a bit as I've worked with the TS590
and the noise bridge I have temporarily borrowed.

So, no worries on that score.

Tom,

Turning down the RF gain is a good idea and turning off the AGC, if
possible, is an even better one.  Of course, the AGC activity would make it
difficult if not impossible to hear the null.  I turn mine off when trying
to orient the beam on a signal but I know not every rig has this function
available.  Good luck.
