I live in Valparaiso and am having problems with receiving signals. Has there been some change that I am not aware of? Things were ok until two weekends ago and then I started to have issues. It seems that each year when the time changes in the fall these channels seem to have problems. I have a rooftop antenna. It is a Winegard CA 7082. I called WCIU on Monday 11/27 and the lady told me to rescan. That did not make any difference. I sure hope that someone knows why this happens. Thank you ever so much.
