Michigan DMR Repeater / Talkgroup Matrix

Borrowing an idea and format from our Hoosier friends to the south, there is now a Michigan DMR Repeater / Talkgroup Matrix. In a nutshell this is a one stop shop that lists every DMR repeater in Michigan, regardless of the ISPC network. This list indicates how to connect to each repeater and the talkgroup / timeslot configurations. Instead of scouring the vast internet for details on DMR repeaters around the state, this list has you covered.

Includes repeaters on:

  • BrandMeister
  • DMR+
  • Mi5 / W8CMN
  • TGIF
  • Chicagoland
  • Crossroads DMR
  • and more!
This data has been gathered from a variety of sources, include repeaterbook, BrandMeister, W8CMN, DCI / DMR-MARC,, and scores of various websites. The most valuable resource however is YOU, the regional experts and repeater owner / operators.


You can use the filter funnel to quickly show just a certain type of DMR repeater (e.g. Mi5 only, BrandMeister only, etc) or limit the list to just "on air" repeaters. More filters will be added as the list matures.

Something wrong? Report it!

If you don't find a repeater on this list, or you find information that needs added / corrected, use the link on the form to request the change. This will go to the regional admins so that the list can be updated.
