Rocky Mountain Ham Radio’s DMR MARC Repeaters:

Lee Hill/Boulder North Repeater: Repeater TX 445.0500/Repeater RX 440.0500 MHz, Color Code 1, DMR MARC (Motorola Amateur Radio Club)

Colorado Springs: Repeater TX 445.0625/Repeater RX 440.0625, Color Code 1, DMR MARC (Motorola Amateur Radio Club) Offline until further notice. Repeater system is looking for a new site. Unsure as to exact restoration time.

Regarding TAC talkgroups and other DMR-MARC talkgroups: Rocky Mountain Ham Radio doesn’t have any plans to add TAC or additional talkgroups to the DMR-MARC presence in Colorado.

We have installed these systems linked to the DMR-MARC (Digital Mobile Radio – Motorola Amateur Radio Club) system. This is a system of approximately 130 TRBO repeaters worldwide. You can find more info on DMR-MARC from their website:
There are some significant differences between the existing RMHR system and DMR-MARC.
1) Users of the DMR-MARC repeaters MUST obtain a radio identifier issued by DMR-MARC. You can request an ID here:
2) Please note that DMR-MARC does NOT use “ALL CALL” on their system. They utilize “TALK GROUPS” for Worldwide, North American and Local traffic.
3) They have an inverted structure for timeslots to RMHR. On their system Timeslot 1 is for Wide Area Traffic, and Timeslot 2 is for Local Traffic.
You should program your radio only to use the following talk groups:
On time slot #1:
World Wide – Talk Group 1
North America (U.S. / English Speaking Countries) – Talk Group 3
World Wide English – Talk Group 13
On Time Slot #2:
Local – Talk Group 2
Mountain Regional Talk Group – Talk Group 3177 (Please see map below for states covered by the 3177 Mountain Region network.)
