Yeah, different sites.
I'll check, because both sites have traffic from Copa Airlines (one site is the airport repeater and one site is a repeater on top of a hill), but I'll probably just program those two sites in two banks and ditch the rest, since they don't have interesting traffic.
So far I have one system similar to what you describe, LCN 05 is one site, LCN18 is a different site, the same people use those antennas, and work fine.
