If you're struggling with am reception, keep trying, it is possible to get it back. I can get stations which have been lost in noise for years, and the sound is good now.

I was surprised to have interference on the FM band due to LED lamps. They aren't exactly TOTL R40 lamps. They're the Sunbeam badged from Dollar Tree. Two for a buck! This house has those can lights, popular in the early 2000's. The switch is on the other side of the wall from the radio.
The FM reception is great when the lights aren't on.
