What is ClearDMR?
ClearDMR is open source, community-maintained firmware for a family of Baofeng, TYT, and Retevis DMR handheld radios. It provides a clean, actively-maintained alternative to the factory firmware, with an emphasis on usability and ongoing compatibility with modern DMR networks.
ClearDMR is a continuation of the OpenGD77 project, originally developed by Roger Clark VK3KYY and contributors. OpenGD77 entered archive/read-only status in 2026. ClearDMR carries that work forward for the amateur radio community.
Supported Radios
- Baofeng DM-1701 — standard and Japanese market editions
- TYT MD-UV380 — standard, 10W+ hardware, and Japanese editions
- Retevis RT84 — standard and Japanese editions
All variants share the same STM32F405 processor and are flashed using the same Web Flasher tool. Choose the correct firmware variant for your specific model.
