Welcome to the Winnipeg Digital Repeater Group -
DMR information page

After a successful fund-raising drive, the Winnipeg Digital Repeater Group purchased a Hytera RD-982 UHF DMR repeater and installed it at 601 Osborne Street. The repeater has excellent coverage well outside of Winnipeg. The repeater has now been moved to our 55 Nassau Street North main site. The Winnipeg DMR repeater identification is VE4DMR with a frequency of 443.675+ using Colour Code 4.

The Winnipeg Digital Repeater Group has expanded! After another successful fundraiser we installed a Hytera RD-982 UHF DMR repeater in Selkirk, Manitoba, July 2021. The call sign is VE4DMS with a frequency of 443.725+ using Colour Code 4.

We expanded our system again! A new Hytera RD-982 UHF DMR repeater was installed in Portage la Prairie, November 2021. The call sign is VE4DMS with a frequency of 444.800+ using Colour Code 4.

All our DMR repeaters are linked to BrandMeister Canada. All use Colour Code 4. Time Slot 1 carries the Static Talk Group Manitoba (3024). Time Slot 2 hosts Local (9), True North (30241), and NorthStar (31273), along with dynamic talk groups upon request. We host various nets primarily in the evenings on Time Slot 2. Please refrain from activating other Talk Groups on Time Slot 2 during these nets. Note that Time Slot 1 is exclusively for Manitoba (3024). Time Slot 2 is available for Local (9), Dynamic Talk Groups, Private Calls, Parrot (302997), and D-APRS (302999 with 300-second beacon intervals). Remember to pause for 3 seconds between transmissions. If you need assistance with your code plug or have questions, contact the Winnipeg Digital Repeater Group. Your support through club membership is appreciated if you utilize the system.

Stay tuned for more projects in the future!

What is DMR?

Digital Mobile Radio (DMR) is a land-mobile radio network standard developed by the European Telecommunications Standards Institute (ETSI).

DMR uses Time Division Multiple Access (TDMA) to provide two 30 ms “slots” per 12.5 kHz radio channel.

Each slot can carry independent voice conversations – this means that each DMR repeater provides two simultaneous voice channels – illustrated in the diagrams below:

Each slot can also have an almost unlimited number of “talk groups”, which effectively function as discrete channels within that slot. Users on one talk group will not hear those on another. I like to think of Talk Groups as “Conversation Labels or Tags”. When the label or “Talk-Group” matches what your radio is programmed to receive, you hear this conversation. Anyone else doesn’t.

DMR provides better noise rejection and weak signal performance than analogue systems by using advanced Forward Error Correction (FEC) and codecs to remove noise and reconstruct signals that would otherwise be lost – depicted in the following diagram:

There are many advantages in using DMR over analog and other digital modes. It's cutting edge and is the same codec used in P25 Phase II Public Safety Systems around the world. Linking is as easy as connecting a LAN cable to the repeater for worldwide communications.
