As I said before, some things it does better, other things
not as well. I repeat that the 15.1 dB C/N threshold is not
sporadic in my case, it is repeatable, and in this case,
better than COFDM can do.

MediaFlo, from Qualcomm, is primarily W-CDMA, which is a
single carrier scheme. It looks like they added a COFDM
option, but I don't know which is being deployed first.
Vcast is W-CDMA, a single carrier scheme.

You are making a bigger deal of this than it deserves. I
suggest that an attractive package from broadcasters will
go a lot further in making DTT popular than any lame excuse
about the RF standard.
