I have a Dish 622 and a Channel Master 3017. I get 28 channels in the SW burbs of Chicago. One station, WCIU 26 Is only 15 miles away with nothing in the way. The signal strength meter on the 622 shows a strength of 99, yet the signal breaks up frequently. This station carries some of the local White Sox games in HD so I would like to clear this up. All other channels come in clear. Any ideas?
