I have birdies appearing every 8.5 kHz (or so) on 40 through 10 meters on my

Hi Steve,

Thanks for the Q in IOTA.

If the birdies are a noise bump that drifts, it's probably from a switching power supply. If they are carriers that don't drift, it's probably some sort of digital clock or radiation of other trash from a digital device.
