Does anyone recognize this moving QRM? Last evening 6:30pm. Band is dead. Ambient noise pretty calm. But notice the slowly moving noise bumps on the K3S SVGA display. Might this be weather radar? https://vimeo.com/157616344
Nope. It's a switch-mode power supply, the sort of thing that powers almost anything we buy nowadays -- it's in the wall warts for all sorts equipment, battery chargers, computers, even built into home electronics.
