Colorado Digital Multiprotocol: democratizing digital by bridging modes

You’ve found your way to the web home of Colorado Digital. We are a group of digital amateur radio enthusiasts who experiment with, build, and maintain a system of multiprotocol talkgroups. We bridge together D-STAR, DMR, YSF (C4FM), NXDN, and P25 under different talkgroups, helping to make it possible for amateurs to talk to each other no matter what digital mode they are using.

We specialize in using hotspots as access points to these systems, although we use terrestrial repeaters as well. Be sure to check out our blog section for posts from our group, and our net page for information on the Colorado HD net. Also join our Telegram Group which carries a lot of useful conversation.
