First off, some radios like the GE Superadio series and other AM/FM/SW
portables are inherently noisier on AC power. Not much you can do about it
other than use batteries for serious listening. Receivers meant for AC power
only are usually better shielded and filtered.


Actually, the GE Superadio III is exactly the model where I discovered
that if I plug it into a computer surge protector rather than into the
wall socket I got much better performance.
