OpenRTX

Modular Open Source Radio Firmware

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:

• TYT MD-380/390
• TYT MD-UV380/390
• TYT MD-9600
• Radioddity GD77

This firmware is highly experimental and is not in a usable state right now, however contributions and testing are welcome and accepted.

For information on currently supported radios and features, see the Development status wiki page.

For hardware and software documentation visit openrtx.org

Compile and flash

For instructions on how to compile and flash OpenRTX to your radio, or just run OpenRTX on Linux see the How to compile wiki page.

OpenRTX was created by:

• Niccolò Izzo IU2KIN n@izzo.sh
• Silvano Seva IU2KWO silseva@fastwebnet.it
• Federico Amedeo Izzo IU2NUO federico@izzo.pro
• Frederik Saraci IU2NRO frederik.saraci@gmail.com

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