I used to live in an apartment building. The landlord said that a tennant was complaining that his brand new TV had horrible interference each night at 10PM, and since I am a ham, was it due to my radios?
It turns out the tennant had a new TV (which defaults to CATV) plugged into the building's master antenna and was trying to watch a UHF channel. I had him flip the setting to "antenna" and the problem went away. Oh and why did the problem show up at 10PM? That's when he turned the TV on to watch his show. No interference problems when it was off :-)
