Just like the 220 line in my ham shack...the same circuit as the tablesaw in my workshop..I told the electrician that I don't machine wood while operating. He looked at me kinda funny.73,Gary K9GS

But its not worth the effort to fix it since I never operate while shaving! tks 73 Frank W3LPL ----- Original Message -----From: "Jim McCook" <w6ya at cox.net> To: rfi at contesting.com Sent: Friday, July 10, 2020 5:14:50 PM Subject: Re: [RFI] RFI Solved After 2 Years Frank, I don't have access to the Lutron dimmer model. The electrician simply stated that it's designed for dimmable LEDs. Perhaps you're dealing with the switching power supply for the LEDs, an entirely different problem. Do the LEDs have a separate PS or are they contained within the actual light? I have had to deal with RFI from many pendant or chandelier LEDs, and even the dreaded strip LEDs, all which have switching power supplies that are radiating monsters. For pedants and chandeliers the little PS (POS) is usually in the back box. I've had luck with installing Corcom filters between the line and that PS. For tough cases or with strip LEDs you have to go to the attic to install a "magnetic" PS, readily available on Amazon. This is just one example: https://www.amazon.com/LEDwholesalers-Dimmable-Magnetic-Transformer-Flexible/dp/B00J1ZVKSQ/ref=sr_1_8?ie=UTF8&qid=1516573754&sr=8-8&keywords=magnetic+transformers+for+LED+lighting In any of those cases the switching PS must be first discarded (smashed or burned works well). 73, Jim W6YA _______________________________________________ RFI mailing list RFI at contesting.com http://lists.contesting.com/mailman/listinfo/rfi _______________________________________________RFI mailing listRFI at contesting.comhttp://lists.contesting.com/mailman/listinfo/rfi
