[RFI] RFI 80 through 10 meters every 10 KHz tracked down to neighbors house

[Michael Carter]

Don, you mentioned the suspected generator of RFI is the LED strip light 'controller.'  You replaced the power converter with a linear bench supply to no avail.

What features of the LED strip lights are governed by the 'controller' box?  Pulsing of the string and/or dimming by PWM would be obvious sources of RF emission.

Even though the problem was 'solved' by the owner discontinuing use of that LED strip light, I am curious about the mechanism of RF generation in the 'controller' box.

Thanks, and 73,
Mike, K8CN

One correction, I probably should have said they were LED strip lights
whereas I called them string lights.
