Welcome to DMR Plus North America

DMR Plus is the original network that developed tools to interconnect ETSI Tier 2 DMR repeaters. It has been popular in Europe for years but now, with the cooperation of DMR-MARC, it has finally arrived in North America and the South Pacific. The DMR Plus architecture is similar to D-Star. Users have talkgroups to converse, to disconnect, and to monitor channel status. Users choose from a large pool of reflectors and move back to the converse talkgroup for all QSOs. The DMR-MARC and DMR Plus partnership is ideal. The DMR-MARC network is robust and reliable. The DMR Plus network is more aligned with experimentation and interoperability of technologies. Think of DMR Plus as the best possible implementation of the former DMR-MARC Sandbox. DMR Plus also supports a configuration that features the traditional DMR-MARC talkgroups like Worldwide English, North America, Latin America, etc. on TS1 and the DMR-Plus reflectors on TS2. The USA Regional talkgroups and the Canadian Provincial talkgroups are now connected to the TS2 reflectors. DMR Plus supports connectivity via the DV4mini USB hotspot and the DVMEGA add-on board for the Raspberry Pi. DMR Plus also features MMDVM connectivity. Be sure to visit the Contact Us link at the top of the page and join either Traditional DMR-MARC or DMR Plus North America. You asked for more control over your repeaters and now you have it!

DMR Plus Reflectors

Dongle Access is Here!

DMR-MARC is excited to announce remote access with the DV4Mini from Wireless Holdings, the DVMEGA using MMDVM, and the Open Spot from Shark RF. You may access any of the below DMR-MARC talkgroups on your traditional repeater or via a hotspot connected to DMRPlus. Somone locally must PTT the talkgroup to ensure the connection is made between the stable portion of our network (DMR-MARC) and the experimental (DMR Plus). The inactivity timeout to disconnect is 10 minutes.
