64 (DT-50) is fine if you live in East Charlotte, but with their 50kw signal, maybe not so great in other areas. Here in Fort Mill, 46 and 55 DT are rock solid, along with all other Charlotte DTs, except WTVI. WAXN also comes in fine, if I tweek my inside antenna just right--all the others are great no matter how my antenna is situated. BTW, it seems Charlotte is set for excellent DT reception (other than WTVI--What were they thinking). Despite what has been written elsewhere, Digital TV is real step forward, with improved reception and more channel selection for OTA viewers.
