We bought a dozen or so average consumer radios, from a walkman to a boom
box to a clock radio, and whatever is in between. On every one, the music in
analog sounds as good as it did before, and switching the IBOC on and off
produced during several days of testing no significant differences on
average radios.

Try it on a GE Superadio III. It's an "average" radio that you can
buy for $49 at Sears. If you can't hear the difference in quality
with the IBOC on, then a hearing check is in order.

Mark my words... IBOC on AM will be a flop. In addition to the
horrendous interference, degraded analog audio, and artifact-laden
digital audio, who would spend $500+ for an "HD Radio" setup, just to
hear the same local stations, when XM or Sirius costs less than half
as much and delivers 100 channels of new, exciting, and often
commercial-free programming? And when the radio stations realize that
consumers aren't going for it, who would spend the $75,000 - $100,000
per station to convert to IBOC?

Arthur Liu's Multicultural Broadcasting tried IBOC on 930 WPAT and
1480 WZRC in the NYC area. But they gave up on it after only a few
weeks on the air, because of the degradation of audio and signal
quality, and because none of these stations' listeners would ever care
to own an IBOC receiver, even *if* they were available in stores. But
it's funny -- you never hear about these kinds of negative experiences
in Radio World or other publications that are rabidly pro-IBOC. And I
know things are really strange when even _David Eduardo_ is speaking
favorably of IBOC. What is the world coming to?
