I do not see any reference to AM HD in those documents... nor would I expect to, since I have not heard anything about IBOC being modified to be compatible with 9 kHz channel spacing. In fact, I am not aware of any HD receivers which even support 9 kHz channel spacing mode on AM.

Why would anybody think the AM HD mode supports 10 khz spacing?

In actual practice the ibiquity AM HD mode would properly require 30 khz spacing to keep its broadtrashing out of other signals.
As long as the carrier is the reference, there is no reason for such signals to park on even 10khz steps.
Now if the carrier osc cannot be set to any other than 10 khz steps, that would limit it.
Would ibiquity be clueless enough to design this for the 10 khz steps only?

I doubt Thais buy many NTSC televisions.

THe AM iboc was designed for North American standards but in a sparse MW band environment I expect that additional sideband space could be accomodated on some channels. As in America, am iboc probably won't be practical in every instance.

We have seen that separate digital bands are, at best a middling success, in-band atleast offers a better chance for developed radio markets to transition to digital.

And now, ladies and gentlemen...back to today's episode of "Dancing With The Insane."

Wasn't the subject of this thread: HD-AM?? Or was it DAB as implemented in Europe (DRM et al) ?? NTSC color TV? AC Line frequency standards? Steam versus diesel? Whether laetrile really works?? Area 51??

If you guys keep up the ducking and weaving, you'll have to provide Dramamine with your posts.

Well, I guess it's weirdly reassuring to see that Mr. Gleason doesn't save all of his contempt for this poster and for AM radio. He also takes a dim view of the United States of America, as is evident from the long list of perceived grievances in his last post.

The Harris and webwire links posted at the beginning of this IBOC detractor-baiting thread have NOTHING to do with HD-AM. Absolutely zero.

And I repeat: if the dozen or so iBiquity defenders left on the planet (and apparently all of which contribute here) have been reduced to pointing to third-world backward countries in their search for HD success stories, they're tacitly conceding the argument about whether the system is succeeding.

I note your lack of response to my comments about what's happened with HD-AM since 9/14. Readers can draw their own conclusions.

My only first hand experience with AM HD is when I drive into Dallas, and then it is based on observations using an analog radio. Some might say that isn't a valid test, but considering that 99.99+% of all radios are still analog, I think it counts for a lot.

Yesterday afternoon I drove into town, and switched my GM-Bose radio from a decent sounding AM station in Tyler to KAAM in Dallas. I couldn't believe what I heard. The fidelity was absolutely awful. It was a jarring shock going from the Tyler station that sounded "round and full." I actually had to switch back and forth a couple of times to make sure I wasn’t hearing things, thinking maybe I had tuned in when KAAM was playing some horrible sounding recording. It wasn’t.

KAAM - a music format station that runs in HD- sounded thin and brittle. There was absolutely no low end. There were no discernable highs either. All that was left was a screechy midrange with a hard to listen to peak about 3-4 KHz. Cymbals sounded like breaking glass and even voices sounded like a message left on your cell phone. Before HD, this station actually sounded pretty good on most radios. They even broadcast in C-Quam stereo.

Perhaps the HD version of KAAM sounds great. That's nice, but most people are not benefiting from this "improvement." Even though I wanted to listen, I simply couldn't stand the way this thing sounded and soon tuned into the analog version of WRR, a classical station, which sounded great.

If this is the price everyone will need to pay to make IBOC work on AM, it is simply too great. In the five or ten years it takes to get enough radios to make this worthwhile, there won't be any listeners for many of these stations. They will have gone elsewhere. There are plenty of other choices.

This looks to me like an incredibly bad business decision. Good Account Executives can probably keep things rolling for a while selling time, even if the station has a TSL of five minutes, but they can't keep juggling forever. I just don't see this working from a business point of view if the technology gets in the way. They'd do themselves a big favor if, at least for now, they'd go back to all analog.

One of KAAM's big advertisers is a hearing aid company. Maybe they are trying to drum up some business for their sponsor? ;D

I'm gonna fly, thank you. Good day and best wishes to all.

Oh, don't leave, this won't take long.

It's ironic how IBOC supporters gleefully pile onto a successful AM operator, screeching repetitively "AM is dead, AM is dead, nothing can save AM but HD, AM is dead" about a guy who turns a BCF every year that impresses appraiser/consultants/bankers

-By renting out much of his airtime and pretending that the soundtrack of a local TV station is his "news dept".
I know you are providing a vital public service,, too bad none of those legions of listeners ever seem to get Arb diaries.

BTW: Is O'Reilly paying you as he does WOR?

(I know, dear visitor. Why, oh why, did I bother to post in a thread started by Lino with "IBOC haters" in the subject line? WHAT was I thinking??)

Simple, so that you can derail the discussion with mocking glib derision. SOP.

all the while ignoring how their pet digital system is absolutely, utterly, dead in the water. .

New receivers coming into market, a whole line of new chips out early next year. Upatate New York, now that's dead.

No new station installs.

Facts?

Major groups turning it off.

Citadel:10 stations These geniuses just hired 67 year old Don Imus.. for syndication. A month ago they hired the 78 year old snapping turtle Bob (Gigante) Grant. Their target listener still uses an Atwater-Kent.

And, now, the formal FCC interference complaints are beginning.

You mean the one you just filed? As we say down here in the City that pays your bills "That and two dollars will get you a ride on the subway" -That's a type of train that runs mostly undergroun,,,never mind.

But atleast you got mentioned in that bastian of accuracy, Wikipedia. I guess they couldn't find any other filings yet, right?

Now, go on and whine about how you and your station have been personally attacked. Atleast this time it'll be true.

Hey now. A-K made some serious radios! I sure wouldn't mind having one -- those peeps have good taste in receivers. ;D

My Part 15's ATU uses an Atwater Kent TRF tuning cap, and a Duck Co. tapped inductance, both from the 1920's.
