I've put chokes in all light dimmers and all LED fixtures.  The switching supplies create enormous noise that feeds through the entire electrical system of the house.  I have to unplug battery chargers and some wall warts to listen to any AM receivers.  Thank goodness for FM!  Love my Scott 16A in my shop for that reason.

I found my interference was coming from my neighbors LED lighting and dimmers. I walked over, called my wife on speaker phone near the radio, and had him turn his lights on and off. He was shocked that his lights would bother my radios across the street. Same transformer for 3 houses, I’m doomed. Too expensive to replace all his lights. Plus every room has a dimmer. Double doomed!
