i am getting a lnb drift message when i check the details box. it says 0x0d,0xat,61.5(e-11) what does this mean and how do i fix it? 61.5 gives me the strongest signal of all my readings.79-80while 110 and 119 run about 52. it is on a dish 500 while everything else is on 1000.2, which has trees at the bottom of the elevation arc. could the trees be why i get low numbers on 110 and 119?
