Wall wart ferrite beads, maybe, but I'd try one of these...
DSL Phone line filter, from Home Depot
Or, this one, because I like the name. :hyper:

Those Home Despot things are for filtering out the DSL frequencies from the voice frequencies so you don't hear a buzz when you're using your telephone. They won't help with RFI issues at all.
Umm, yea, my bad. Not (and never have been) a DSL user.
The correct one would be a telephone RFI filter, like the "KY".

OK, I made some progress. I used a T130-2 torroid on the wall wart power cord. About 10 turns. 40M and down I still have problems with 5W. 20M and up it works FB at 100W. I no longer have problems on the dummy load on any band using 100W. I did not test on 160M or 30M.
id find a better built wallwort.
I already tried that. I used the wall wart that came with my D-Link WiFi Router which previously had no problem and it didn't help.Quote:

I think a project is in my future! I have everything I need except the meter.

That would be very cool. I was going to run down to the radio shack tomorrow but I doubt they have anything.
Well, you could always tear one out of their analog meters. Take the case and mb back and tell them it doesn't work. Probably be a week before they realize the movement is missing. They are 100ua FS as I recall.
