There is an extensive User Guide however becuase the firmware is evolving very rapidly, sometimes the User Guide does show the latest features or functions. This does not mean that new non-core functionality changes will be rejected, but bug fixes and core functionality PR's will take priority User guide New developers are welcome to participate, but currently the focus is still on getting the core functionality working and existing bugs fixed. The project is under active development by several developers.


Some functionality like Dual Watch may also not ever be implemented, because its equivalent to the Channel / Zone scan function. Not all functionality provided in the official firmware is likely ever to be part of this firmware, because some features like encryption are explicitly prohibited for Amateur Radio operators. However it does currently support some core functionality that the official firmware supports, including sending and receiving of text messages, or Dual Capacity Direct operation, or Dual Watch operation etc The firmware is relatively stable and provides DMR and FM audio transmission and reception, as well as a DMR hotspot mode. The AMBE codec is not open source because of potential copyright problems, and instead uses binary sections from original manufacturers firmware. Open source firmware for the Radioddity GD-77 (aka TYT MD-760), GD-77S, Baofeng DM-1801 (aka DM-860) and Baofeng RD-5r, dual band DMR / FM handheld transceievers, for Amateur Radio use.
