Interesting jorgek! I'm using a DMS SF-500 digital signal meter and always though I had to be very specific on my TP & frequency #'s. I have 39 inch dish locked on 97W and have 10750 lnb on side bracket. Can lock in 99W but can't pick up signal from 101W with the DOD channel?? Thats only 4 degrees differance and I thought the dish would pick it up only maybe at 55 %. Hmmm!!
