They belong to the new one, the "Central Georgia Regional blah blah" system. I've been trying to get someone local to help us out and give us some descriptions, but no one seems interested. I'm not local, and don't have any way to monitor now that my local radio is dedicated to the fire feed. @maw originally reported them - maybe he's been listening and can offer us a little more.
If anybody isn't sure what we're talking about - we have 5 talkgroups - 100, 102, ... 106, but no description of what each one is. i.e. - what is talkgroup 102? If you're been listening, what do they typically talk about on 102? License lookups? Is that the tactical channel they move to for large incidents? Is the the meter-maid channel? The same for the rest of the talkgroups. Are all the dispatches on 100?
I would guess so, but purely a guess.
