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 DMR repeater and installed it at 601 Osborne Street. The repeater has excellent coverage area well outside of the City of Winnipeg.

Please join the Winnipeg Digital Repeater Group and enjoy noise free communications with cutting edge DMR digital voice!

The DMR repeater is linked into BrandMeister Canada server. We have set up a static talk group on
Time Slot 1 - 3024 Manitoba. We have Static talk group NorthStar (31273) on Time Slot 2. Time Slot 2 can also be used as a local repeater and is set up as Local 2 – ID 9. Time Slot 2 can also be used dynamically to bring up other talk groups from around the world. We also host various nets throughout the week.

Please remember to keep TS 1 only for Manitoba 3024. TS 2 can be used for linking etc...

The repeater identification is VE4DMR with a frequency of 443.675+ using color code 4.
If you require help with code plugs please contact ve4wdr@gmail.com and one of our members will be in contact.

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.
