Yeah if you rig up a 1kw tube amp and start splattering a big chunk of the FM boardcast band, jam their cash cow mobile networks or run around with a GPS jammer near an airport you'll get a near immediate PP slap but beyond that they'll maybe send a car eventually. They don't have the ability to detect and locate this stuff in real time and, IMO, probably shouldn't for privacy reasons.
Marriott was jamming for years, until they were forced to stop. Keyword: years.
If someone is making temporary jamming attacks (even on GPS or cell), unless you do it at your house or stationary, you ain't getting caught.
I know 'a friend at the hackerspace' who did a .25w GPS spoof to make the city look like it was in Moscow, Russia. Nobody responded.
There's lots of types of jamming, not just white noise static.
"A first offense is a misdemeanor punishable by up to a $10,000 fine and/or up to a year in jail. Subsequent offenses are felonies punishable by up to 2 years in prison. In practice, this might result in only a civil action by the FCC. But it is forbidden by Congress and can be punished by imprisonment." https://law.stackexchange.com/questions/94617/is-deliberate-....
You can fuck with RF as much as you want, as long as you A: don't do it constantly, B: don't do it in the same location every time (at home), and C: don't do it in a band belonging to someone who has their FCC field office's number on a post-it note and has paid the FCC lots of money.
The FCC told the police they didn't care, it took a bunch of HAMs running around to find the source and politely ask them to maybe fix it or at least consider turning it off if someone else complains again.
