I had a similar problem. My neighbor in Bowie, Md. kept complaining about me making his stereo, TV, etc.. talk while it was even turned off.
He complained to me countless times so I called the FCC to see what I could do. They told me to work with the guy and install filters and the like on the devices in question and as long as I was operating legally there was nothing to worry about and If he refused help tough luck.
Consumer Beware!
He refused my help, even refused the help of a friend that I asked to help (Bob, KC3VO) who happens to be the engineer for a TV station. After several complaints and his refusal to accept any help I turned the tables on him. He had an electrostatic air cleaner attached to his furnace. So every time his furnace interfered with my enjoyment I went knocking on his door. When he asked how I knew I told him I can hear it, and he prevented me from listening to my radios.
After a few times of knocking on his door like he did mine, the complaints stopped. I guess he was still baffled how I could actually tell his furnace was on.
Although I can relate. Every time I operated 160 meters my phone in the shack would ring off the hook. Evidently I was adding enough induced voltage in the telco line to make the telephone think it was ringing.
An inline filter solved that.
