I was more worried about PWM controllers and harmonics, even with a
conventional power supply. I guess I'll have to demand to listen to an
installation to see if it generates RFI or not.
The slides for my tutorial talk at Visalia and Pacificon lists several
battery powered receivers that are very useful in evaluating devices and
systems for RFI. k9yc.com/publish.htm The title of the piece is about
building contest scores by killing noise. The most useful is a vintage
Kenwood TH-F6A VHF/UHF talkie that has wideband RX. I've seen other
talkies with this capability. There's also a very nice consumer
AM/FM/shortwave RX that WA6NMF turned me on to 6-8 years ago.
