Have you ever wondered where the 3127 talk group number and the beginning of radio ID’s in Minnesota originated from? The simple answer was the DMR-MARC group (Digital Mobile Radio Motorola Amateur Radio Club). However the origin actually can be traced back to the beginning days of the cellular radio networks and their need for identification numbers for each radio network. Check out this link and notice the similarity to our assigned numbers. https://en.wikipedia.org/wiki/Mobile_country_code. The MARC website also has a description of where it all began.

Minnesota MARC Std TalkGroups
Talkgroups
- PTT (On Demand) talkgroups do not carry traffic on the local repeater until a user “Activates” them by clicking their PTT button or “kerchuking” the group. Once activated, the PTT group will carry traffic until communications cease for a set period of time.
- Always On talkgroups are continuously active across all repeaters regardless of local traffic.
