It's a good idea, but too severely limiting since almost all monitors
now run on 19V. Thus far the HP 23es is fine. I ran RTTY with it next to
KPA500 on several bands with no issues. Final test will be pointing the
6m EME array at the shack and listening. The monitors look really good
and were on sale at Best Buy for $119!

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.
