CBS/Infinity and IBOC-AM?

Here in Los Angeles, we've implemented HD Radio on AM 1110, Radio
Disney - a children's formatted music station. I would describe the
aural result as "startling" - 14 kHz stereo, very low noise, no
obviously noticable artifacts, no multi-path in an automotive
environment - in short, it's *very* hard to believe you're hearing an
AM station.

Compare this to a *typical* AM receiver (not necessarily a Drake R8B or
Eton E1/XM) with a mono 3.5 kHz response and loud buzzes evey time you
drive under a power line, and you can see the attractivness to the
Broadcasting community. "Here, finally is a way to compete with new
technologies" [programming issues aside!].

This is my main contention that this digital technology does not sound
better. It is still way to low a bit rate for me to call it "good
sounding." Yes, you don't get the static and power line noise but the
trade off is low quality sound filled with digital artifacts. Basically
you trade background noise and interference where it exists and trade
it for low quality sound all the time. Other trades are drop outs
instead of selective fading for example. This is just a mixed bag of
good and bad at the cost of obsoleting all receivers made since radio
began. I can't think of a worse trade off and it is just plain stupid to
try and cram it down the general publics throat.
