# codec2 | FreeDATA
My attempt to create a free and opensource TNC with a GUI for [codec2](https://github.com/drowe67/codec2) to send data over HF channels. 
The TNC itself will be completely controllable via network.

## Under development
The project is still a prototype and not usable at this time.
