Brutal, thank you for confirming my actions. However your adminoishments also apply to me because I learned the Radar procedure a long while back and really just kept applying it to each new box we were equipped with.
Like I said for me the simpler the better. Start with max gain WX mode point at the sea and trim the radar up until the picture is clearer and reduce the gain to remove sea clutter. Served me well but maybe I should have read the books a little more.
