What kind of signals do I receive with my 622 and 522 Dish receivers and 1000 dish. I know I receive some analog only stations. Are these converted to digital at what point or not at all. These same analog stations do broadcast a DT signal according to their web sites but on a different channel number and Dish doesn't provide those. They are in my "Locals". I have three TV's that I assume are "Digital" being as they have HD tuners in them. Only one receives SD signals that are good and that is the one that the 622 supports HD programs on. I will add that have a fourth TV, that is an older CRT that receives all channels just fine(excluding HD's of course). Before I purchased 3 LCD digital TV's, I had crt's that had a good pictures on all of them. I am trying to figure out if reception will improve, when Dish starts using the DT signals of my locals? Or do I need to go to complaining to manufacturers? Yea, I know how much good that will do, but I have been surprised at times!! By the way, an antenna is not an option where I live. Smoke
