It's been a while since I've looked into this, but last I knew it was legal to listen to any band you want, but illegal to transmit on any band for which you don't posses the required license, if any.
Then there's all kinds of rules about transmit power. For instance, last I knew you could transmit unlicensed on the public FM and AM radio bands so long as you're under some minimal threshold - I think it was 1W.
- VLM 13y ago"I think it was 1W." LOL no, you know .gov they make it as complicated as possible. If I recall the AM is DC input power limited and the FM limits are some weird field strength which is non-trivial to measure. Google for 47 CFR 15 and you're looking for part C 15.221 and .239 probably. You can read this stuff for free at gpo.gov. There are about a zillion other part 15 bands you can legally operate under if you're willing to bother figuring out how. If you're smart enough to figure out how to legally operate part 15, you're certainly smart enough to get a license to operate part 97, which doesn't have even a fraction of those goofy restrictions and is the original techie social network.
