[Elecraft] Computer Noise ruining 20 & 30m

[Alan D. Wilcox]

Hello,
I gave away the feeble old PC I had by my radio equipment and replaced 
it with a newer one ...

Now I have S9+ noise wiping out 20 and 30 meters.

Using same keyboard, mouse, monitor; just the PC in a new case. 
Evidently it has a
noisy switcher supply in it. Tried 110V in-line filter, also different 
110V house circuit,
but still have noise. Grounds don't help. Don't happen to have a box of 
toroids for chokes.

I've got an old PC supply or two in the junk box, but hoping something 
else might fix.

Any thoughts on an easy fix?

Thanks,
Alan
