My daughter gave me an abandoned Dish 500 with DP twin lnb that I want to use for 61.5. I subscribe to Americas Everything Package,local package and HD package. I own an 811 & 501 on a Dish 500,DP twin for 110 & 119. I bought a DP 21 switch to hook up the second dish to the 811. I used an inexpensive satelitte finder to point the dish initially. I got a strong signal from the meter but nothing on the check switch screen or the signal screen. Do I have to call E* and tell them I am doing this so my receiver will recognize the 2nd dish?
