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.)
