Well I thought this was interesting. The wireless falls over here in the caravan every now and then. To cut a long story short it’s when we run the microwave to cook things, yep that simple. 
I was reminded of the chance of that when I remembered years ago reading that a radio telescope was picking spurious signals randomly. It took them a fair while to work out that it was when the microwave in their kitchen was stopped before the timer ran out. Weird, but it helped me work it out.

The microwave turns the radio off and on again?

Yeah, it’s really confusing the aliens.
