Firstly, our testing of the new DMRPlus interconnection talkgroups, which include DMR USA (TG133), DMR UK (TG143) and DMRPlus South Pacific (TG153) has been very successful and we have decided to roll these talkgroups out to all repeaters connected to our network. We have also added DMR+ Quebec – French (TG131), and DMR+ Latin America – Spanish (TG134). This will allow any device connected to the DMRPlus network, including commercial Motorola or Hytera repeaters, homebrew MMDVM repeaters or base stations, the upcoming DV4mobile and DV4mini users worldwide to access users on either the DMRPlus or DMR-MARC networks. The rollout has already started and will be completed over the next few weeks.

Secondly, we have decided to allow all of our US regional talkgroups (TG3169, TG317x), and Canadian provincial talkgroups (TG302x) to be interconnected with the DMRPlus network as well. By combining the stable and robust nature of DMR-MARC network with the flexibility and experimental nature of the DMRPlus network, we hope to create a combined global DMR network that suits the needs of all ham DMR users.

With regard to the traditional DMR-MARC talkgroups, we have heard numerous concerns expressed by our users around the potential impact of experimental devices on these talkgroups, so accordingly these talkgroups will remain exclusive to the DMR-MARC network for the time being. These talkgroups include:

– Worldwide (TG1)
– Europe (TG2)
– North America (TG3)
– Oceania (TG5)
– Worldwide German (TG10)
– Worldwide French (TG11)
– Worldwide English (TG13)
– Worldwide Spanish (TG14)

We believe that by providing a two tier approach to talkgroups with some designated as robust and reliable, while others open to experimentation and feature development, we can provide our users with the best possible DMR experience.

In addition, we would like to thank all of our loyal users for their generous contributions to our network over the last seven years. Many of you have invested time, hardware, and financial resources to our network, which has helped us to build the world’s largest DMR network consisting of over 500 repeaters in 60 countries that is used by over 10,000 hams every day. Most importantly, your efforts have helped to change the face of ham radio digital communications forever and we hope the hobby is all the better for it.

Again, we appreciate all of your support and look forward to making DMR great for the benefit of the entire ham radio community.
