 Chattervox implements a minimal [packet radio protocol](#the-protocol) on top of AX.25 that can be used with a terminal node controller (TNC) like [Direwolf](https://github.com/wb2osz/direwolf) to transmit and receive digitally signed messages using audio frequency shift keying modulation (AFSK). In the United States, it's illegal to broadcast encrypted messages on amateur radio frequencies. Chattervox respects this law, while using elliptic curve cryptography and digital signatures to protect against message spoofing.

While I'm very excited to see that interest in the project is high, It's quite unexpected and I have spent very little time testing the software (aside from automated tests). If you have a problem, [please submit a detailed issue](https://github.com/brannondorsey/chattervox/issues) and I'll have a look. I'll be writing a tutorial explaining how to get up and running with chattervox very soon.
