Mac,I have not had the opportunity to get out there and search for activity since Donjon Marine lost the contract, but when they had the contract they were using Marine VHF Ch. 78, 156.925. Of course, there was also related traffic on Marine VHF Ch. 13, 156.650, which is a common Marine VHF for any port area. I'm hoping to get a chance to get out to St Simons or Jekyll after they get back to work and do some searching for activity.
