Well, thanks for that summary. That was quite insightful. If you can
actually get better AM reception wtih HD or IBOC then it would be a
great addition to AM radio. Personally, it seems somehow scareligous
to listen to XM or Sirius. I just miss the commercial aspect of radio.
So, anything to keep AM/FM viable would be great. Do you mean by
fidelity sister stations that they can actually run separate
programming -- we have a station near me that broadcasts on like 94.7
and then also has a second transmitter located nearby that broadcast on
94.9 - but they are the same programming sounds.

Thanks for your insight.
