I have a dish 500 and I put my receiver on a dish 1000 and the channels were different. I thought the channels you receive are programed on the receiver it self. If you stay on a channel that the 1000 doesnt pick up it shuts of the box and it starts trying to find the signal and then goes to a channel it can get. Will this hurt the receiver for me to switch it back and forth between two different dishes. The ID location changes too. Can dish tell if that receiver is being used on another dish besides the one it is supposed to be on? The receiver has not be hooked to a phone line since 07-2005. I would appreciate some help because I am trying to learn some of this stuff. I dont want to change any programing in the receiver just want to kniow some of what can happen switching it back and forth
