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.

Instructions for DV4Mini Software Configuration



1. Download and install Visual C++ 2013. (both x86 and x64 for 64-bit machines and x86 for 32-bit machines).

2. Download and install the DV4mini software

3. Follow the screenshots to configure your personal information in the DV4mini software in the DV Control tab.

4. Go to the Expert Settings tab and select you nearest server and adjust the DMR - QRG Correction in the Expert Settings tab to show the lowest error rate. Red is high error, Yellow is medium, green is low error. You need to transmit to see the bit error rate (BER) bar. We have seen +150 to +300 Hz be optimal, depending on the type of radio you use.

5. Choose the nearest DMR Server with an IPSC2 or IPSC2m prefix.

6. Choose a talkgroup after selecting the TS2 radio button. Then Choose "Connect" on the DV Control tab.

7. Go to TS2 TG9 on your radio for all calls. (This is similar to what D-Star does with the "T" channel profile.)











Configuration of MMDVM on DVMega/Raspberry Pi

1. Purchase a Raspberry Pi and a DVMEGA
2. download the latest Jessie Western D-Star Widget Image
3. Follow these helpful instructions.
4. Below is an example MMDVM.ini file that works well. Our partners in the UK, Phoenix, are hosting this service for Europe. You may use their server in the event ours is down.
