FreeDATA

[!NOTE] Development has slowed due to limited maintainer time.

[!WARNING] Latest release accumulated many changes towards the 0.18.x release, including a new broadcast feature for group chats. If you run into issues, please fall back to the more stable release, v0.17.8.

FreeDATA is a versatile, open-source platform designed specifically for HF communications, leveraging codec2 data modes for robust global digital communication. It features a network-based server-client architecture, a REST API, multi-platform compatibility, and a messaging system.

Please keep in mind, this project is still under development with many issues which need to be solved.
