I originally had a Dish 1000 dedicated for 129, and replaced with a Dish 500 for better signal... lately I have repeaked the 500 several times but still lose TBS and rarely get my recently added KRQE from LIN... I put the 1000 back up today and just got through peaking it on 129. I am getting 2-3 points lower on the signal strength, but have no problems accessing any of my Mpeg4 HD locals or TBS so now am thinking the LNB is going south on the dish 500 ( a DP Single)and am using same on the 1000 as the DPP was DOA when I took this dish with me Deer hunting... I took down my 148 Dish 300 to put up the 1000, so thinking of moving the 500 to 61.5 ( I have my deactivated 811 outside now with a monitor)
