Do you have a solid ground wire between the supply and the radio? If not
the radio is about 1/8 to 1/4 volt above DC ground.
You haven't chopped the 3rd pin ground have you? For safety reasons, it
must be in place.
Some have reported with the supply on the left it makes noise, on the right
it does not. I may have my left's and right's reversed. Anyway, I think
you get the idea.
The ONLY noise I have from a switching supply is from the charger for my
laptop computer. I've purchased three different ones. All produce noise.
As to the station supply, I use Astron SS-30M's or SS-25's. Have three and
all are quiet.

I have four TT switching power supplies I use for various rigs including
Ten-Tec and Elecraft. Never a noise issue. One is a recently acquired
940,
a perfect match for the Omni VII, in my opinion.
