AM HD TURNOFF PACE ACCELERATES

*snerk*
Yeah. That explains why the number of AM stations near me broadcasting is smaller than the ones that are off the air in some form or another (some without any STA or anything). And this is in a region with fair to very good ground conductivity.

Please tell me who "touted" HD as a "savior"?

Former FCC Chairman Kevin Martin and Commissioner Kathleen Abernathy, commenting on formal approval of IBOC in October 2002:
"We support today’s decision selecting in-band, on-channel (IBOC) as the technology to be used by AM and FM broadcasters for the introduction of digital broadcasting. Digital radio... holds great promise for the revitalization of AM service."

Then, Ms. Abernathy added this stunning endorsement, which reminds me of a QVC sales pitch:

Might be interesting to interview her again and ask if she's actually satisfied with HD Radio, now that she's back in private practice and has had the chance to try it. Wouldn't surprise me if the HD Receptor or Directed Electronics set (compliments of NAB) is gathering dust in a closet and she spends much more time listening to analog radio and the iPod.
For that matter, let's ask all those former commissioners what they really think, now that eight years have passed.
The real knee-slapper was Abernathy's comment about being "sure that broadcasters will work cooperatively with adversely affected parties" in the "few cases" of interference.
Much like giving someone the finger and referring them to your lawyer comprises "working cooperatively" with them.

No, AM is doing fine all on it's own....in a death spiral! LOL!

So, in other words....2 people (actually 1) in 2002 mention it could help AM.
Hardly "touting it endlessly".
HD is simply an additional feature that adds some extra function to radio broadcasts. Take advantage of it if you like, don't use it if you don't.
I have never heard anyone, even those who are proponents of HD call it a "savior".

fficial&client=firefox-aThe only people who keep mistakenly keep touting that line are HD Haterz.
So much for "endlessly touting".

Who's a troll? Anyone who presents an opinion (or fact) that you don't like?
I think they call that denial.

Denial is a defense mechanism postulated by Sigmund Freud, in which a person is faced with a fact that is too uncomfortable to accept and rejects it
LOL!

WGCI hiss noted back on this morning.
As far as the turnoff on AM is concerned; the sooner the better as far as I am concerned. It doesn't work very well, nobody is listening, and it just causes massive interference. If stations turn it on and off for random periods (sometimes for days at a time) and only industry insiders notice, what does that tell you?
I fear that we will have a long wait to be rid of HD on FM. It may have to wait until terrestrial radio broadcasting ceases to be relevant.

I sure hope not. I think that companies that drank the Kool-Aid early on will tire of shelling out piles of money for the latest generation of HD equipment when nobody heard the previous generations of HD gear. As I've said before, HD is pretty much isolated to large markets, HD Alliance stations, and larger public radio stations. Unfortunately this small group of stations creates an insidious amount of interference to stations outside their markets. Interference is at the top of my list of why HD needs to go away, but there are several other reasons why it will go away. And probably sooner than later. The relevance of terrestrial radio is diminished by precious few things; one of them is HD Radio.

I'll give you interference on AM HD during the night, which is a good reason HD should not be run on AM after sunset. But as for daytime operation or FM HD, what interference? I've been a lot of places in this country and heard a lot of stations running HD on AM and FM and have yet to hear any interference within a station's protected contour that I could directly attribute to another's HD sidebands.
While it's true that the sidebands wipe out everything on either side of a channel on FM, there is not a single market I'm aware of where two stations' contours overlap when they're first adjacents. As much as out of market listening is a part of our lives as radio geeks and insiders, that listening is simply not guaranteed to anyone, and any station that's been milking fringe reception is subject to losing that for one reason or another at any time.

Stop Zach stop! You're making too much sense! HD Haterz can't handle anyone that doesn't tout their gospel! LOL.

gr8oldies.....didn't you know that's their mantra...and the whole message of this board? ;-)
Zach, I think you're missing the point. I'm not talking about DXing or interference outside a station's protected contour. I'm also talking about the commercial FM band, although I agree with audioguy that the reserved band has its own brand of HD trouble due to its D/U protection scheme and the fact that there are a lot of public radio stations that received "grants (laundered tax dollars)" to easily acquire and install their HD interference generators. But I digress. I completely agree with you that fully-spaced, first-adjacent, commercial FM stations almost always do not have intersecting protected service areas (KATY/KRTH is a notable exception) -- a scheme which works well when each of the stations is transmitting a signal that is ONE channel wide. Adding HD creates a signal that is THREE channels wide. Believe me, you don't want to be a Class A seventy miles down the road from a full power Class B running one of its HD sidebands ON YOUR CHANNEL at -10 dBc. It gets even worse if the culprit is a super-powered Class B. As my example stations are separated by 70 miles, they are NOT in the same market. Interference doesn't respect Arbitron market boundaries -- it can and usually does come from outside one's own market.
