The last 2 days, NBC 39 HD stopped and was shown on 79-356. Today, many more channels were lost on my QAM tuner. KUSI is 79-359 today rather than 51. 8-1 (CDS HD is gone. 10.1 is gone. So I did another full rescan and 51 and 39 are still missing but most channels are elsewhere again. Up in the 77 to 79's or so. Anyone map these out yet. Anyone else have the same QAM issues?
