LOL! That’s certainly one good way of dealing with it. Maybe an unmarked van with antennas parked across the street might also encourage some circuit breakers to get pulled!

We went around the neighborhood with some very intimidating-looking antennas, electronics, and laptops.  The interference ceased after about 30-minutes of 'being obvious' on the hunt for the problem location.  We suspect whomever was conducting the operation saw us and got scared.  It's never come on again, even after 5 months.  Take all the geeky equipment you can, even if it doesn't work anymore, lots of antennas, even a few things that go 'click' or squeal.
