As far as I'm concerned, allowing a signal to be broadcast, at a
frequency that is already allocated to something else, is always going
to be a bad idea (unless it is a system using very directional
antennas). From what I've read in this NG. HD-Radio does just that. It
ends up allowing digital signals to be transmitted on frequencies
already allocated to analogue signals. Whoever thought that would be OK,
obviously either doesn't understand radio, or simply doesn't give a sh*t
about the consequences.

The big boys pushed IBOC because they wanted to do whatever they
could to _prevent_ the creation of a new all-digital band. They
feared that such a new band would level the playing field so the
small broadcaster would have just as good coverage as they did. That
was an intolerable and frightening idea to them.
