You should have the 1000 reinstalled and the DishPro dual used for 129 replaced. These lnb's give intermitent signal loss at variable times and read only half the transponders on their way out. Also try another check switch test as Dish issued a signal meter software upgrade that also resulted in a similar problem. You will also notice that a signal strenght that used to read 110 will now read around 75.
