I think they would . . . might be a combination of both. But I suspect power surges are the more immediate culprit. Depending on how your radio is wired, it could set up induction in the circuitry andthat would give it enough power to switch on . . . a bit like hot-wiring a car.

And you will do better. You're already doing a lot better, and you're doing something about it, which is even more heartening.
