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.)

73,
