I agree with that. What would attract people to HD Radio is seeing
their favorite stations (like mine: FM97) multiply into 3 or 4
channels..... thus giving more choices to the listener.

For every additional channel a station adds in IBOC, their main
channel bitrate MUST suffer, as bandwidth is taken away from
it, so it of necessity MUST cut back the bitrate.


Oh well. Somebody else in this forum just got done telling me,
"Listeners don't care about quality", so it shouldn't be an an issue.
People want variety, and lots of stations. And that's what IBOC-FM
provides.

BTW:

IBOC does have an advantage over DAB. DAB only has room for ~100 kbps
per station. IBOC provides each digital FM station with 300 kbps.
