Josh,
See if you can find a monitor with an external power supply that
produces 12 volts.
If you can accomplish that, connect the monitor to the shack 12 volt
power system instead of using the switching 'wall-wart' that comes with
the monitor.

That's a good clue, Bert!
So turning off the monitor should kill the noise. Easy to test.
Funny you mention it. I'm going to test a prospective new monitor today. I'm
trying a smaller one so I can fit 2 on the operating desk. I find lots of them
are unusable, either the monitor or it's PS generates noise, or they are
susceptible to RF.
