DMR Division

WikiPedia: Digital mobile radio (DMR) is a limited open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) and used in commercial products around the world. DMR, along with P25 phase II and NXDN are the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division and TETRA uses a four-slot TDMA in a 25 kHz channel.

Getting started in DMR can be a bit scary but once you get the concept of how to program a DMR radio, you will be able to concur DMR. We are working on some videos and things to add, but with DMR that’s the one thing you can find pretty easily so do use youtube to find some great videos! Please hang with us as we are building out this section of the site!

Talk Groups

  • Local TG 2 – Stays on the same repeater and isn’t routed to any other repeater. This talkgroup stays local to each repeater, so it is not available to hear on the Brandmeister Hoseline. NB: Tulsa, Ketonville, Bixby, Mounds are NOW in cluster mode with TG 2.
  • Oklahoma TAC TG 31400 – This talkgroup is to be used for special event activities. An example of this would be the OKC Memorial Marathon or some other ARES event. This talkgroup should be used on Time Slice 1, and during actual events, the repeater owners will make these static on the repeaters in the affected areas.
  • Central Oklahoma TG 31401 – This talkgroup links the Depew repeater and everything west of there into this channel. This static talkgroup is in Time Slice 2, in the Central Oklahoma Standard assignments.
  • Eastern Oklahoma TG 31402 – This talkgroup links the Depew repeater and everything east into this channel. This talkgroup is a static talkgroup in Time Slice 2, in the Eastern Oklahoma Standard assignments.
  • OK Statewide TG 3140 – This talkgroup links all of the Oklahoma repeaters into one group. This talkgroup is used for the Monday ARES net. This talkgroup is a static talkgroup in Time Slice 2, in the Oklahoma Standard assignments.
