Not sure if this is related, but I have been getting "noise" on my radio
when I have some of my lights on. I switched out most of my incandescent lights to LED's. I've found the ones near the radio will cause interference when they are turned on. Since I typically only listen to radio during the day, I just turn the lights off when using the radio. Like I said, I'm not sure if this is related to what you're experiencing, but it's worth a try.
