No. It's that news/talk is mostly on AM so it is the band being
disrupted. I can't make any sense of the approach taken implemented HD
on the AM band so I'm grasping for a reason.

1. AM audiences are declining rapidly
2. AM listener age is increasing each year.
3. AM formats like news / talk, when put on FM, increase younger demos
almost instantly.

I don't see this happening.

4. This shows the main reason (as does all kinds of research) for the
decline of AM is that it sounds just so bad. HD is an attempt to make
it sound better and make it viable again.

Problem is HD doesn't sound any better.


It sounds worse. It has a greasy XM-like sound to it.


Actually, it has CD-like sound. The difference is that analog FM has a
preemphasis curve, which is not used for HD.


David,

What does "CD-like" really mean?

Is it...
same noise level?
same frequency response?
same dynamic range?
same freedom from compression artifacts?
same distortion?
same skipping and pausing as I drive down a rough road?

The hype says like a CD, but never defines what it means.
