Hi. I have a cabin 75 miles away from my home. I installed a dish on the cabin and took one of my receivers from home and it worked fine...except for one thing. When I went to the local channels, it said I haven't paid for those channels. Now the local channels where my cabin is are different from the local channels at my home. Is there any way I can get local channels to work in both places? Do I just need to program the receiver with the zip code of wherever I am?
