Correct me if I'm wrong, but my recollection is that ATSC in Mark's apartment worked perfectly well, at long last, after the CE vendors had designed a receiver as they should have done from the start. My rendition of this story is that early ATSC receivers were known to be compromised, early ATSC broadcasts were known to be compromised (low antenna height and sometimes egregiously low transmitter power), almost as if the CE companies and the broadcasters WANTED to see DTV fail. We might never know what exactly went into the "cold fusion" receiver that worked perfectly well in Mark's apartment, but we can make some educated guesses (tracking front end, dual IF, attention to noise figure). And we do know that early ATSC receivers could not even be bothered to use the 8-VSB training sequence, never mind complex demods, able to correct for phase as well as amplitude distortion. The single-carrier standard may not be ideal for everything, although it does have its advantages (e.g. even for co-channel interference, which will be a big deal with the repacking), but I think people then, and now, are making a bigger deal of "modulation" than it deserves. Just to rehash old posts. Did I mention that in analog TV days, I got only 3 channels "well," and the remaining 8 ghosty? And now I get 37 channels "perfectly," of which 11 are HDTV?
