Thanks for the reply Jim.
In one of my tests last night, I turned off all circuit breakers in
the house except the one powering the rig's power supply and the
problem remained. I have been suspecting the power supply since day
one and I will probably pull the battery out of my car tonight to test
this theory. Nothing has been added to my house or neighborhood since
I was last on the air that would make this kind of noise. The noise
does go away when the antenna is removed.
I was finally able to tune in WWV this morning but it wasn't as good
as it usually is.
The power supply is a 25A TrippLite unit and I don't recall off the
top of my head if it's a switcher or not.. it may very well be.
