Helpful information before operating on DMR Repeaters

Definitions of Abbreviated Terms and conditions when using the DMR Repeaters:



Is a channel access method for shared medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots.[1] The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. This is the format of digital that you’ll be using why’ll on the Mototrbo network.



Time slots are two dividing signals within the fixed frequency that allow more than one user at a time to use the same frequency but only of opposite time slots.

Amateur Motortrbo DMR repeaters are equipped with (2) available time slots.


Talk Groups (TG)

Designated channels within each individual time slot.  Inside the two time slots, it's up to the owner or trustee of the repeater to have the ability to carry any of the many talk groups available based for that particular time slot. 

Talk groups can vary from local to worldwide coverage. With that being said virtually all DMR repeaters have certain TGs on a fixed timer and others TGs carry the full-time activity.


Note: Only one active TG per TS can be used within that assigned repeater without interfering to another user that could be using the same time slot. DMR repeaters will respond to any last transmission per any time slot. So before transmitting be sure to take notice of the desired TS to ensure that it's not being occupied by a different TG from another ham. Please be cautious and respectful, as we want this to be a positive experience to all.


Talk groups that are labeled (FULL-TIME)

When a TG is active at all times and never defaults to a closed timer. This is true with Local (ts2), Indiana Statewide (ts2), Midwest (ts2) and North America (ts1).


Talk groups that are labeled (PTT-ACTIVATED)

When a TG has been assigned to a closed timer and only becomes active when via PTT. Once PTT has been briefly pressed once and released that TG will then become open and active for the assigned minutes. The TG will remain open as long as it has incoming traffic from the repeaters local receiver but not from the network itself. Thereafter the TG will go back to rest until further activation.

The soul purposes of these timers are to maintain traffic control and allow Full-Time TGs and Activated TGs the ability to be used. As you’ll experience there are some TGs that are very active and can tie up the repeaters usage. This is not just a local repeater it’s apart of the whole World.
