H22 - I learn something every day! However, I just repeated the experiment with the very same result, so suspect it's not just coincidence. What I don't know is where the interference is happening. Is it with my indoor antenna or with the cable or connection to the TV? Whatever it is, I do know it is worth trying switching off a nearby appliance. One of the telescopes we run on Mauna Kea has exactly the same problem; if someone tries to use their cell phone at the summit it can really screw up observations...
