I'm starting to get the DMR bug a bit after finding a DMR system just went on the air in my area. I'd like to understand a bit better how this works.
Specifically:
It appears the repeaters support multiple talkgroups, split between two timeslots. Does the subscriber unit affiliate with the repeater when it's turned on (without the user keying up)?
If I key up a radio on the right talkgroup, it makes sense that it could be routed to the right place, but if I'm just monitoring, how does the repeater know which talkgroups to transmit?
I monitored the local frequency on my drive in today and heard nothing (on an analog radio). I expected to hear digital noise. But maybe there's only noise if there's an affiliated subscriber unit in the area?
Just trying to sort this all out.
