Not so good.

The above is a picture of the test setup. I used 5 turns of #20 magnet
wire left over from the PA-100 Filter Module, attached them to 6' of
RG-58U coax through a bannan plug-to-BNC adapter, and draped the coil
over the picoPSU-60-WI. The other end of the coax went directly into my
SDR-1000.

The above is the test result at 160m. Noise floor goes up 30db. Nuts. I
could do more, but is there any point?

P.S. - Any other ideas?
