For purists, yesterday I took the effort to tweak my dish such that now the USALS coordinates I enter are precisely my exact dish lat/long coordinates as confirmed using a GPS at the dish. Result? Reception is no different than before when I cheated by manually touching up the USALS longitude just a little. Except I do have a rosy sunburn from standing in the sun for some time yesterday. I still can't get 15W anymore presumably due to summer putting leaves on the tree sticks that I like in winter time.
