Mmdvm repeater.

The MMDVM software is a fabulous development realised by Jonathan G4KLX allowing to built a multimode digital hamradio repeater. Indeed, it can manage the three digtal modes DSTAR,DMR and C4FM. MMDVM is composed of two physical parts.The DVM Host (dvmhost) software suite, provides the primary host computer implementation of a mixed-mode DMR, P25 and/or NXDN or dedicated-mode DMR, P25 or NXDN repeater system that talks to the actual modem hardware, and the networking core (dvmfne) that provides a centralized network service that interconnects DVM Host (dvmhost) and other endpoint applications allowing networked communications.1a) Background. This is an article about personal, low-power hotspots, also known as personal access points 1, not repeaters.(For info about digital repeaters, see: How to make a MMDVM Digital Repeater by N5AMD and Repeater Builders.)

Uncategorized.

and a MMDVM board is a digital only device. on the flip side you can use AllStar on GMRS to link repeaters together and I suppose simplex nodes as well (no repeaters allowed on MURS) there is plenty of GMRS linking going on via AllStar. but you must run it on a private network as you cant cross GMRS and Amateur services.
