Bob or anyone:

I wonder what would happen if I disconnected the ground wire between the
ground rod below my shack, and the ground on the electrical power box.  It
is only a short wire, and I can't believe it should make a difference, but
with this sort of thing, you never know, I guess.

I've tried some snap-on RF chokes on the output of my TS590, and the common
port of my Alpha Delta antenna switch, but so far nothing has changed
significantly.

Will keep at it here.

Tom,

That means that RF is coming down your coax lines from your antennas, and
that you have a long ground wire which will radiate that Rf.  You also could
be having a ground loop between your electrical and RF ground rod.

I would try a coax RF choke at each antenna and or connecting a second
ground wire that is a few feet longer which should lower your RF ground
reactance.
