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.

It sounds to me like the noise you're hearing is externally
generated. IE when you turn on the ATT the noise drops. The ATT
is almost the first thing that the signal sees and if it's
working the rest of the rig is working. Does the noise go away
when the antenna is removed? I would think it would since the ATT
drops it.
What power supply are you using? Is it a switcher? Have you added
any battery chargers since your previous rig? I had a battery
charger that I used in the basement and it drove me batts for a
couple of weeks until I figured out that the switcher in it was
causing the problem.
The Paragon I belive tunes the broadcast band. The signals there
should be well above the S7 noise level. See if you can pick up
signals between 530Khz and 1700 Khz.
