However, it does appear from observation that _reducing_
the bandwidth to the IBOC analog requirement makes the majority of the
narrowband AM receivers out there sound better.

Certainly not in my experience! The stations I've heard running IBOC
sound noticeably inferior to those not running it, even on a
narrowband receiver. It also seems to me that the interference
issues are not trivial, and interference from IBOC does affect the
primary service areas of adjacent channel stations, at least in some
cases. And the whole nighttime issue is a major problem.

Let's face it -- AM IBOC is a kludge. It's a very technically
impressive kludge, but a kludge nonetheless. It creates bigger
problems than it solves. If AM can't survive without this, then AM
probably can't survive. And maybe in the 21st century, it shouldn't.
Maybe we're trying to make a horse-and-buggy compete with the
automobile by putting the horse on steroids. It won't make the horse
fast enough, and it will be harmful to his health.

Next time I'm in L.A. I'll have to check out KTNQ. However, the Delco
AM stereo tuner in my car is not narrowband.
