We moved this summer and took Dish with us. The installer hooked us up (he was another story), but no HD channels for Chattanooga, TN local networks. We had the HD local channels from Bristol and Roanoke. Are they not available here? I tried talking to someone, but they were more than willing to send a tech I could pay for with either their protection plan or by the hour for something they should be able to handle. If I get HD, do the local networks here in Chattanooga provide it through Dish?
