I am a video and sound engineer. There is clearly AM radio coming from my wall heater. An earlier thread on this topic discussed the possibilities but ultimately left the subject with an assumed crazy old lady's false perception. I assure you this is happening. There is a 50,000W AM station (6x 150' antennae) within a half mile and interference from this station is pronounced in the area. My speakers and recording equipment are useless here. Now the radio is clearly audible out of the wall heater. I've attempted to ground it better, shield it with sheet metal, disconnect all the wires, to no avail. The incessant RF bombardment is a concern but the consistent annoyance of hearing the unwanted radio all night is truly horrible. The wall heater started acting as a radio receiver around the same time we had solar panels installed on the roof. Maybe the panels/added wires are adding to the building's electrical load and exacerbating the already insufficient grounding? Help please!
