Hi Pete,
It did help to put a couple ferrites on the PS control cable. It's now
barely perceptible, but that's with an urban noise level. It's
definitely coming in via the antenna, something over 100 ft away.

I just tried that with my KPA-1500, Scott, and could not hear any
change. Another one of those RFI gremlins!

I guess it just shows how little I've been on 10, but I've had the
KPA1500 for over a year now, and I just noticed that when I turn it
on, my noise floor on 10 goes up about 3 dB. (And that's from an
urban noise floor.) It's pretty flat over much of the band, not
typical switching supply noise. Has anyone else experienced this and
found a cure? (Other than using the old amp tube.)
