The Multimode Digital Voice Modem project, which supports most of the digital voice modes used in amateur radio, is about to get a software upgrade through the efforts of Jonathan Naylor, G4KLX, and with funding from ARDC, the Amateur Radio Digital Communications foundation.
According to Newsline, the open-source modem project supports D-STAR, Yaesu System Fusion, NXDN and more than 80% of the hotspots and repeaters on the Brandmeister-DMR network. In addition, Naylor is working on developing high-speed packet modes that will support narrow-bandwidth digital voice signals.
