I've got an unusual situation that I'm hoping someone here will know more about than Dish CNS. I currently have dish HD from satellites 110, 119, and 129. I take one of my Dish DVR 622 receivers from my house tailgating but have never had success hitting 129. Is it possible to buy a Dish 1000.4 and use the 61.5 instead to get my channels? I can't figure out if the receiver can be switched back and forth at will. My other option is to get a Dish 1000.2, but i'm still wary of that 129 satellite.
