I am in northeastern michigan, and I've had a Turbo HD/ 722k setup for about 3 years. My dish is tuned to 110,119,129. I just found out that I can get my locals in HD on 61.5. Can I retune to this satellite, and if so, what other ones are required for the to tier programming. Also, i'm not sure if I'll have to get dish to reprogram my receivers. Any help is appreciated.
