"it sounds like the fcc really doesn't care about anything"
Oh, they care. But they are a government agency and they care about 1) Their budget and 2) Mandates. So when it comes to "civilian" "free" radio services?
One of the stated purposes of amateur radio, and a reason for complying with the Morse Code requirement, was to "ensure a pool of trained radio operators" for military draft. Often swept under the rug, that was one reason for tolerating pesky hams, so Uncle could draft some morse operators in the next war, which was expected to be an atomic one with the USSR.
Move past that and the question is, well, "Go away boy, you bother me" as WC Fields used to say. The FCC doesn't have the time or budget to care if some ham is bugging some other ham who can't figure out a way to experiment, improvise, and overcome while ragchewing on his drive home every evening. (To put it bluntly.)
You want them to step in? OK, first you have to do the heavy lifting. That's part of what ham radio is about, the hams are supposed to keep their own house in order, and actually DO everything they can (like their own RDF) before bothering the FCC. That's what you get with a cheap license. ("Free").
Personally, I'm less than amazed at the many folks who will ***** ***** ***** about jamming (and I'm not talking about anyone here) but they can't find any time or money to bother DOING something about it. Like DF'ing, or even innocently calling the suspected party, to see if the jamming stops while the phone call is in progress.
So build or buy some foxhunting gear, get in a car, and start drawing lines on a map. Who knows, you might be able to pin one down, but until you've done that....
