Thoughts about HD Radio

I got the Boston Acoustics HD this past week, and although I think it's a good unit, I have some questions about whether or not HD Radio will be accepted by the listening public. Here are my observations:

-The one and only HD2 channel on the only HD FM station (so far) in this area signed on a day after I received the unit. Even though it's just an automated jukebox at this time, at least it's another listening choice. However, after observing the sound quality, the HD2 has as many digital artifacts as listening to an XM music station, and is not as good as Sirius (this is my observation and opinion). Is this going to be the case with all HD2 stations?

-A bulk of radio listening is done in cars. Many new models have radios in which aftermarket units are difficult or impossible to install. iBiquity will need to work hard to secure the OEM market, which may be hard since GM and Honda are major investors in XM, and the same with DaimlerChrysler's involvement in Sirius. These companies most likely would like see a return in their investment with the satellite companies, so they may be resistant to add HD to their radios.

-In order for there to be sub-$100 HD receivers for the new technology to be adopted by more people, iBiquity will need to reduce licensing fees. Is this going to be a problem for them, or do they make much of their revenue through the broadcast equipment industry?

Other than that, the sound quality on the main HD1 FM is great, while I don't think AM HD has a future. I bought the Boston based on my experience with the analog version of the Recepter, and if HD fails, then there is always a good analog tuner to fall back upon (as well as inputs for satellite). I'm trying to make a fair observation on HD, which has its fans and detractors. Any other comments are welcome.
 
You will see more and cheaper HD radios flooding the market soon. They will become "ibiquitous"!
I say this with all the vigor and enthusiasm with which I said it about AM stereo radios, several years ago.<P ID="signature">______________

It sounds like they may not have the split configuration set properly. They may not be running an even data rate for HD1 and HD2. Also I have found the processing for HD2 is totally different than HD1 or analog. If they just came on with the HD2 signal give the engineer some time to work with it. It may take over a month to find that sweet spot.

Some of the HD READY radios required an external box (like satellite radio). Some of the newer units are all in one units which should be much easier to install.

in that case do i need to say you were wrong about that :)..most people even today dont know am stereo even exists..i took a poll about hd at work the other day.guess how many co workers knew of it?? yep..none!!

note to the NAB..satellite radio..its worth paying for!!</P>
 
Of course I was dead wrong about AM stereo, but I was dead right when I made two other predictions, both in the mid to late nineteen sixties:
1) Some day, FM radio will replace AM radio as the dominant music source.
2) Some day, I will listen to radio directly from a satellite to my car.<P ID="signature">______________

Don't be so hard on yourself!

On a related note. Can HD-AM be stereo? Maybe you could still be right?

HD-AM is in stereo.

Sorry to belabor the point- are any AM stations broadcasting in stereo? I had heard that WOR was not some time ago. How does it sound?

Tom Ray, Buckley's Director of Engineering, tells me WOR is in stereo when IBUZ is on. I haven't heard it. He says it sounds great.

We could give IBOC all the time in the world, but to some people it will still sound like crap. No audio codec is perfect at IBOC's bit rates (32 to 96 kbps). In fact, no audio codec is perfect at any bit rate -- some listeners will always detect artifacts with any kind of lossy compression scheme.

However, most consumers could care less about audio quality, just as long as the programming is something they enjoy. That's why XM and Sirius are taking off, despite their truly horrendous audio (both in terms of audio processing and codec artifacts).

WBYU AM 1450 (Radio Disney) in New Orleans has their IBOC running and it sounds equal to analog FM stereo. Also, no buzz on the analog signal.
