Atlanta Fire Talkgroups

[KD4YGG]

There are four (4) talkgroups listed for Atlanta Fire with "unknown" or "?" in descriptions.

Can anyone identify these as to specific use?

AFD Unk Resp 19660
AFD Unk Tac 19653
AFD Talk? 19662
AFD Unk Alt 19656

Thanks in advance...

19660 is used by Arson investigators.
I have 19653 listed as MED2 but have no listing for 19655.
