Looking for a solution to an annoying problem.  I am based at SC99, a private airpark.  Each time I take-off or land, my Chelton fires off a barage of warnings.  (terrain, obstruction)  Warnings start in the pattern, and don't end until shutdown.  SC99 is entered in as a waypoint.  What are some of the possible solutions to this issue?

Thanks,
