Well I'll make an effort to go thru 10 every time I am on the boat, but I swear it has been dead as Monty Python's parrot for years. I almost always give a CQ on 28.400 to no results. You know how to keep freebanders off 10? The real way? USE IT. They'll stick to <28 Mhz where it is quiet then, at which point it will not be a ham problem.
