A HAM license doesn't help you: you cannot legally use the amateur radio bands to transmit an internet connection.

I suspect the Amateur HAMmers would detect and enforce that: I imagine there are HAM goonsquads.

I thought the rule was no encryption. They theoretically have an entire ip block available.

The rules also prohibit commercial communications (i.e. pecuniary interest). There are some limited exceptions which depending on your use may be enough.

That said, ham radio is a fun hobby regardless. If you are into IP stuff on ham radio, it's not too hard to get an ip on the ham IP block /8.

Amateur radio does have a tradition of self enforcement which is part of my the FCC continues to grant privileges. People practice RDF for fun but I know people who have used to to find people intentionally interfering with other stations.
