I was in Charleston from Sunday afternoon through Monday lunchtime and since it was a Federal Holiday on Monday with reduced MilCom activity, I decided to listen to some Charleston Port activity. I had the 159.855 Charleston Pilots repeater programmed in, but instead of analog activity I heard DMR activity on Slot 1, Color 1, Talkgroup 200. The radio traffic was definitely from Charleston Pilots and that Slot/Color/Talkgroup combination was the only one I heard used. Perhaps the local listeners will find some other talkgroups active over time.
