I am still in violent disagreement with you here, Bert.  The digital
transition would have been much better off if the Sinclair petition were
accepted in 2000.

8-VSB, perhaps just the current ATSC implementation of it, still produces a
net negative atmospheric pressure.   These 5th generation Zenith chips
finally have (mostly) reproduced 1999 COFDM reception performance, and
nothing more.  They do not reproduce 2004 COFDM performance, and by the time
they can (if ever), Moore's law predicts that COFDM would have moved the
goalposts back even farther.

Why do I say that?  Because we have been broadcasting ATSC for just over 6
months now, and we own a first generation Sony, a first generation Unity
Motion, a recent vintage Samsung, and a few 4th generation Zeniths, all
consumer receivers.  In addition, we own Sencore and Videotek professional

There is something in our ATSC exciter that goes wacky once every two weeks
or so, and the Sony and Unity Motion receivers will not even acknowledge
that our signal even exists.  Sometimes the Samsung will work, sometimes
not, while the Zenith and the professional monitors seem to think that
nothing is wrong.  The fix is usually rebooting the exciter, even though the
manufacturer cannot find anything in any of the operating parameters that
causes some receivers to choke.

We literally have to confirm with 5 different receivers before we can be
confident that our signal is "on the air" and receivable by all of our
viewing audience.
