I live in rural Iowa close to a county line that divides between to DMAs(Des Moines and Cedar Rapids). I can view my Cedar Rapids locals by entering the the four digit numbers(example 9155 ABC). But cannot enter 9 for ABC. I have installed other 522s that were not close to county line and was able to see and enter 9 ABC from the guide. Is this a common trouble with spot beam so close to 2 different DMAs?
