Hi folks, looping back to my situation where I had installed Amico LED Wafer
lights in my shed that were generating 6 db of noise to my antenna. Based on
Scott’s suggestion I installed Corm 20VK6 line filters on each circuit as close
as possible to the first light in the chain (1 on each of 3 circuits). The RFI
is now completely eliminated. Thanks to all and Scott for the suggestion.
