Transmit and receive commercial amateur radio digital voice protocols


I’d like to gauge interest of the community in using the LimeSDR for some common amateur radio modes: Yaesu’s C4FM and D-star. There exists an opportunity to make them work with the LimeSDR however the development and testing effort is quite large. Would like to know if people are willing to volunteer time for development and testing and their own hardware to make this work.
The scope of the project would be to integrate the OP25 GNU radio libraries with a simple graphical user interface. First steps have been done in this direction and task estimation has been performed.
