Talkgroup 2505, appears to operate in the City of Tulsa, most likely a type of public works due to the discussion of traffic lights. Anybody with more information?
I do have two other TG that don't seem to match up in the old system. P25 1523 = TGID 24368 and P25 3443 = TGID 55088 both have popped up every now and then as well. If anybody knows what those could be, that would be great.
