For those who are unfamiliar, encrypted or not radio signals can still be tracked down. Normal communication is like everyone in a room speaking English and we all understand each other. Encrypted communication is like speaking in gibberish that only a few can understand. BUT everyone in the room can still hear that a person is saying something.
Triangulation is a thing. If you become a pest licenced operators (see radio fox hunting) and maybe the FCC themselves will be able to direction find you easily if you aren’t careful. $7-10k is the base rate for fines for this stuff if it came to that. If you fuck around near aviation, police, fire, or other similarly important radio frequencies you will find out VERY quickly.
fun fact lora bands (the ones meshtastic uses) are mostly outside of amateur bands and have encryption enabled by default. They don’t transmit very far on their own though, they need other meshtastic devices to relay messages over longer distances. Business band licences allow encrypted radios too.
Maybe if you are in a rural area you can try it with basic FRS/GMRS walkie talkies where there isn’t a licencing requirement and by extension maybe a bit more leniance if you claimed you didn’t know it was against the rules.
True, thank you!
