Did anyone try out a single-conversion COFDM receiver in
Mark's apartment? Apparently, the current crop of Freeview
receivers are single conversion. The first gen was not.

The answer is likely simple enough, John. Our transmitters
are often not co-located. In places like NYC, where the
spectrum is full, this becomes especially problematic.

And, of course, there's no one on this list willing to tell
the whole story on COFDM reception issues.
