My problem with stray RF isn¹t the TV or other electronic appliances, but with the exterior motion sensor lights. 500 Watts on 20 meters turns one of the three pairs on (always the same one). Since they are hard-wired into the house, clip-on ferrite would be hard to do. I can live with it if I have to. . . only effect is to scare the wildlife. But, suggestions, anyone?
