my guess is a bad power line transformer. track it down like CK said and call the power company. they will come out and fix it. (when they can get to it)
i wanted to make a quick point on grounding since it was mentioned.
you need to be careful about how and where you are grounding your equipment.
you can make things worse, and even dangerous by creating new paths to ground right through your equipment.
i know this sounds counterintuitive, but its better to not mess with grounding unless you're going to do it right.
sticking a ground rod in the ground with a wire running up to the base of your antenna may help cut down on some static, but its not gonna do squat if your antenna takes a hit, or if lightning strikes near it.
if that happens, that electricity will be looking for any and all paths to ground.
it will use ALL available paths in order to get there.
if you have a piece of equipment that you think is "grounded" but its not at the same ground potential as another ground, like say that ground rod that is connected to the antenna; then your radio becomes the connection between them. you dont want that!
ALL your grounds, including the AC mains ground, need to be tied together.
there's more to it than that, but i just wanted to get people thinking about safety.
hijack over.
