Thanks for the insight. I would have hoped that my antenna (a remote coupler
SGC-230 which feeds a 135 ft longwire sloper against an 80 ft tower with
direct guy wires as an counterpoise) would be tuned enough and have
suficient rejection to work but does not seem to make any difference as
compared to my other antennas.

As I have been informed, is a consequence of using a single conversion
receiver, of which all of the others mentioned are not.

Thanks Tim, I will look at that. I should note that none of the other radios
that I have (ProII, MarkV, HQ-170, FT-847, etc.) exhibit this problem. It is
unique to the SDR-5000.

Yep. A highpass BCI filter inserted in the RX signal path using the RX
loop.
Like this one. I have never used it, so I do not know how well it works,
but this is the type of filter you are looking for.

Subject: [Flexradio] AM Broadcast on SDR-5000
Whenever I am on 75 meters AM during the day and it is quiet, I can hear an
AM broadcast station that is about 5 miles from me which runs 5000 watts. It
is not a spur, but rather just a signal that I can hear no matter where the
SDR-5000 is tuned. The signal will disappear if the antenna is disconnected
and is definitely ingress to the SDR-5000 and not the external speakers. It
is present on all bands. Not a big deal just can be rather annoying when all
is quiet and I am on AM. It is not as if I am in the near field of a 50KW
powerhouse. Any ideas?
