Well he's partially in luck. At least for the time being.
For most of the state GSP uses a base-mobile arrangement without even going through repeaters. Of course this can be tricky to listen to the mobile side without a good antenna and a high location. In the Atlanta area however, they do use the Atlanta TRS although I don't know what the talkgroup(s) is/are or any of the specifics are so maybe someone else can help there.
I can hear the dispatch on 154.680. It's not all that much activity compared to local police.
As someone else pointed out, Roswell is just a matter of time before they switch over to a new system. I don't know that its confirmed yet that it will be encrypted but I think it's a pretty safe bet that it will be. Cities like that aren't real big on transparency.
