Their transponder is very weak. A few days ago something happened to it, and the signal strength got cut in half what it seemed like, and it was perfect blue skies in my viewing area. Then, a day or so later, it went back to normal, and my normal is around 25 in quality with a 30 in dish and viewsat ultra, in north Fl. The only reason I noticed is because I programmed it into my favorites and flip through it all the time.
