The OpenRTX project

OpenRTX is a free and open source firmware for digital ham radios, top-down designed with modularity, flexibility and performance in mind.

Currently OpenRTX is being actively developed for the following radios:

  • Tytera MD-380/390
  • Tytera MD-UV380/390
  • Tytera TYT MD-9600
  • Radioddity GD-77
  • Baofeng DM-1801

A detail of the project's current development status is available in this page.

To run OpenRTX on your device, look at the users' guide.

To experiment with OpenRTX or just take a peek under the hood, go to the developers' page.

If you just want to take a look at the code, go to the GitHub repository.

OpenRTX was created by:

All this was made possible by the huge reverse engineering effort of Travis Goodspeed and all the contributors of md380tools.

A huge thank goes to Roger Clark, and his OpenGD77 which not only inspired this project, but as a precursor, provided a working code example for the GD77 radio family.

A warm thank you goes to SP5WWP and the M17 community for bringing their libre protocol into our obscure undocumented hardware.

Also thank you for donating hardware to the project:

  • M17 Project
  • laurivosandi

And thanks to everyone who donated via LiberaPay.
