I know this has come up but I think this problem is unique. I have an SL 3 and I can recieve 101 at 97 % , 99c at 90 % 103cb at 88 % but cannot recieve 99s,103s, or 103ca my zip is 12842 and when I used dishpointer I am set to specs I have tweaked the dish every way I can, but still do not get all the channels. I have a tree stationed to the southeast of the dish could these other sats be blocked by this tree. Any help is appreciated. Thanks
