Got home tonite and could'nt get my locals, had most of the other channels. Did a quick check switch and the 522 sat. tuner one had my 3 sats 110,119.129 but sat. tuner 2 only showed 110. Went to my 211 and 311 and did check switch and everything was fine with them. I have a DPP44 switch feeding them all. Is my switch going bad or is it the 522 or something else. Any ideas?
