Yes could be the reason. Unfortunately. If it makes you feel any better the set up you have is the "correct" one in your situation, it gets you your locals in SD and all the other available channels for whatever package you have. It also is not impossible that Roanoke HD will move to 61.5 at some point.There is a steep hill behind the house the way the dish points. Direct Tv could not even get a signal. Could this also be the reason I can't upgrade to the hopper3? They said it's not compatible with my dish.
