I am new to scanning and receiving DMR.
I have been monitoring a local school system that has a one frequency DMR repeater.
I understand that the color code is similar to a NAC in a P-25 system.
I have received 3 talk group ID's, 1000, 2000, and 3000.
I have identified TG 1000 as the buses and 3000 as teachers at dismissal time.
My main question is the time slot.
The scanner has always displayed the color code (9) and one of the above TG's.
The thing that changes is the time slot. The TG's are showing as being in slot 1 and 2.
When I see a posting on radioreference it usually shows a CC # folowed by a TG # then by an SL #.
Do the TG's on a single frequency DMR repeater change time slots? No data such as GPS is being transmitted in the apposing slot, at least from what I can tell.
Thank you for your responses.
