So I can get 61,74(My true south),79,89,91,93,95,97,105. What I want is 72 for the nbc channels and 83 for RTV. My setup is fortec 36 dish, coolsat 5000,moteck 2100. I had the church channel on 72 but I never got nbc mux. I have tried both usals and 1.2 I am afraid to play with the elevation because even though it can be off by 5-7 degrees I do not want to lose any of the channels I currently have.
