What frequencies do they use there Larry? I assume all simplex, but any other frequencies? I'm not too far from there, usually listen to Atlanta's TRS but I'm interested in what else I can hear.

172.15, 172.90. Definitely simplex. Heard them on MARTA when we were leaving the airport. Hit on each frequency. Very rare to catch them talking.
