Your "editorial" is on track, IMO. The problems identified by the FCC are
mostly common receiver issues, which are easily and relatively inexpensively
solved. The latest 8VSB demods fronted by a good receiver, as described by
S. Birkill, would be a very good start, unfortunately that requires a
motivated CE community.....
