Hi-Fi AM demodulator testing w/IBOC

I.B. Iquity declared:

And again (for the hundreth time) who said a station is FORCED to convert to IBOC? No one is being forced to do anything.

Not yet. Working for a major broadcasting company, you should already know this is coming.

IBOCRocks echoed:

First, and most importantly, NOBODY is required to run HD, nor required to buy an HD Radio.

Thank you Tom Wells, zumahans, dbdigital and others for the voices of reason here.

You're welcome.

Granted Ibiquity and friends are not a cartel in the OPEC mold but look what we have here.

About half of Ibiquity's investors are media conglomorates who own the vast majority of stations in the major markets. Apparently that isn't enough for them. They have been urging the FCC to relax the already ridiculously liberal media ownership caps. And now they want to control, regulate and price fix the only FCC-approved method for terrestrial digital radio transmission and what they perceive will be the savior of their precious radio "properties".

In short, the media conglomorates won't be content until they control it all. Doesn't anyone else besides a few of us see a problem here?

Of course, they'll gladly throw back (or leave alone) the small minnow, non or low-revenue producing stations that are tucked away in some burg or are straining to rimshot a market. By the time they're through muddying up the airwaves with IBOC, those stations will have been forced to go dark anyway (or sell out). In the meantime, the NAB will loudly proclaim to the FCC and Congress that local ownership and competition is alive and well.

Yes, maybe I'm one of the Chicken Littles proclaiming doom prematurely. But it's better that than being one of the ostriches here who have their heads stuck firmly in the ground.

IBOCRocks proclaimed:

Problem is, you're sending mixed messages:

It won't get off the ground, yet it will kill analog radio.
Click to expand...

I never said that it won't get off the ground. I have said that I hope it doesn't get off the ground. I have also said that I THINK this technology will eventually kill analog radio if it becomes the chosen one. Perhaps not in my lifetime, but eventually.

Public won't buy it, yet the public will have to buy it.
Click to expand...

I have never said that the public won't buy it. I have said that it currently appears the public isn't interested in it and is presently not buying it. I have also said that the public will eventually be forced to buy it IF iBiquity is permitted to reach the point where it can have its public offering because at that point, its goals will have been realized.

The FCC won't approve it, yet the FCC will push it through.
Click to expand...

I haven't said the FCC won't approve it. I have said that I hope the FCC won't approve it. I also haven't said that the FCC will push it through. I have said that the IBOC cartel has lots of influence on the FCC and if the public permits them to get to the point where the FCC approves the technology as THE digital radio technology in the U.S., then it will, in fact, have been pushed through the FCC by the cartel regardless of its real technical qualifications for such.

There is simply too much money riding on the success of this technology for it to fail. iBiquity will do everything corporately possible to make sure it is ultimately accepted by the public.
 
"There is simply too much money riding on the success of this technology for it to fail. iBiquity will do everything corporately possible to make sure it is ultimately accepted by the public."

Never has a "technology" been met with such apathy and hostility - well, iBiquity is going to have to hold a gun to our heads in order to by HD radios. Nothing like having to force a "technology" on the public, when they could care less. Yes, this could fail, as iBiquity is already two years behind paying back to investors - iBiquity is reaching the make or break point, as the article has pointed out, and J .P. Morgan has determermined that HD Radio will not bring in revenue. Satellite Radio never had to sell itself like HD Radio.
 
"Satellite Radio never had to sell itself like HD Radio"

What are you talking about? XM & Sirius have been advertising and subsidizing car installs since they started.
 
No, it never had to forced on, or "sold", to the public they was HD Radio has - and HD Radio has been a big failure ! :D
 
Who is forcing HD on you? Is the government coming into your home and forcing you to listen to IBOC radio? I know the people behind XM and knew about it's creation and what went on behind the scenes long before you heard about it. The Sats are failing due to a terrible economy for one thing. Let's see where BOC is in five years. This Christmas will be telling when more radios are available on the general market. Any comment that HD is dead is the wishful thinking of people who obviously hold an agenda. Whatever that agenda it will have no effect on what actually occurs in the real world.
 
---->Who is forcing HD on you?

The companies that are screwikng up my analog radios by trying to increase market share with this halfbaked intgerference nightmare.

------>Is the government coming into your home and forcing you to listen to IBOC radio?

No, it allowing the major players in radio to act as if they are the goivernment.
 
The only people with an "agenda" are those peddling defective, expensive, HD Radio iBiquity system for fun and profit.
Those who are HD opponents are just asking for the newly added, destructive, HD Radio buzz and adjacent channel interference to be turned off, and disappear, from their analog radios, can hardly be said to have a profit motive or "agenda". HD Radio opponents just want back what they had before, and was taken away by an incompatible, destructive, unnecessary, unpopular, digital hybrid HD Radio system.
The only "agenda" is the plan by HD supporters to get a proprietary, destructive technology (HD Radio) approved for their benefit, at the expense of the public.
HD Radio approval, (to benefit the few, at the expense and inconvenience of the many) is certainly the only "agenda". Extensive lobbying, formation of the "HD Radio Alliance" cartel, and hundreds of millions of dollars have been mis-spent to promote an inferior, proprietary, incompatible, defective, digital system to profit a few large corporations, and interfere with analog broadcasts used by hundreds of millions of North Americans.
HD Radio iBiquity adjacent channel hybrid digital mixed mode broadcasting, does far more harm then good, or then can be justified by any slight over hyped fantasy benefits that are claimed to be public gains by HD supporters.
 
And here we go around in a circle again. Which IBOC station is interfering with your operation? Here in NY we currently have four 50 KW IBOC stations operating and they cause no interference to any of the non IBOC stations I've always heard. The stations are on WFAN 660 KHZ (I can still hear the 620 in our market with no trace of IBOC interference and the same for 690, a low power out of market Conneticut station) and WOR 710 KHZ, (I can still hear 740 on Long Island with no trace of noiise from IBOC) WABC 770 KHZ (800 KHZ WLAD in out of market Danbury Conn. is also clean here with no IBOC interference) WCBS 880 KHZ ( 1KW WRKL at 910 had not been effected by the WCBS move to IBOC. I can still here it in NYC with the 88 IBOC exciter operating). In fact I think the fear mongering isn't warrented. I say let them turn on their exciters and deal with any problems one at a time. By the way if you have an IBOC radio you don't hear any "buzz". Saying that IBOC audio is noise is like trying to receive FM audio with an AM receliver using slope detection. The audio sounds fuzzy, but use an FM radio and the sound is a clear with full fidelity. This is not a cut & paste from an opinion piece, this is a real world observation and one I can and have backed up with audio demonstartions and my demos didn't contain left channel buzz and marginal fidelity.
 
Good question. I can say this, WABC has turned their IBOC exciter on pre sunrise and I still can hear everything I normally do. Stations such as WLAD are not audible in my area pre sunrise but on 800 I get a excellent interference free signal from CKLW on 800 Khz. As a matter of fact with my Receptor and its DSP I can listen to WLW 700 Khz even when WOR is running IBOC during critical hours. I have noticed minimal service disruptions to out of market signals at least here in NY. I have more problems with WNYC's switch to 820 (formally 830 central limited). WGY used to be easy here near NYC now all you hear is annoying analogue splash on 810 and we used to hear WCCO every evening on 830 And WBAP (820) was pretty easy here on 820 Khz too. No longer though. To much WNYC QRM. Same for 1190 staying on 24/7. WOWO is no longer an easy catch in my area and lastly for now, 1160 Khz used to bring in KSL at night but no longer. Now WVNJ in Oakland NJ covers any chance of hearing KSL. Deregulation caused more problems for the listener than IBOC could ever cause.
 
I'll have to talk with Tom Ray about that. I know him personally, He's the head of our local SBE chapter and he's just turned on a new transmitter plant. Where was the interference, central PA? WLW never caused any interference to those of us in NY. If i could attach pictures I'd show you some from the SBE field trip to WOR's new facilities prior to the new site becoming operational.
 
By the way if you have an IBOC radio you don't hear any "buzz".

And if you have an analog radio, you do hear a buzz.
Until everyone rushes out to replace all their existing analog radios with crappy HD Radios (about the same time hell freezes over) there will be buzz.
 
I have numerous analogue radios and when tuned properly I never hear the digital sidebands and I have a few analogue super radios. Sorry I can't help it if an idiot doesn't know how to tune in their radio properly. In my area IBOC is not an negative issue and by the way, I've been a professional for over 30 years in major market radio.
 
Looks like you are in the minority - you must be in a fringe, or low-IBOC area. Of course, you are pro-IBOC and nothing you say can be believed.

Tell me, maestro, how is it that I am an idiot for tuning my radio PROFESSIONALLY?

Does someone need a resume as impressive as yours to go from 750 to 760?

How exactly do you tune in a radio professionally? I mean, the days of slide-bar analogs are largely over. All my radios are PLL tuned, digital.

I mean, it's either on 1070 or not. And when 1070 is IBOCing, 1090 goes to hash, and that 100kw station (in Mexico) is less than 140 miles from here, with 1070 between us at 30 miles distant.
 
Again and again I live 25 miles from manhattan and have posted IBOC demos. I don't have the problems you are talking about and I was talking about good oldfashioned analogue tuning on a GE superradio. That radio does not have PLL nor does it tune in steps and yet the only stations I can no longer hear are first adjacents on my analogue radios. There are no first adjacent stations who's protected contour are effected. I don't care if I am alone or in a mass. I know what I hear and I know when I read a line from a group of people who have no idea what they are talking about when it comes to what is and what isn't protected coverage. A Mexican station 140 miles away is not protected at your location. Buenos Noches.
 
So an AM station from 140 miles away that puts a 7mv/m contour over the desired city is NOT protected from HD hash? Where do they send the listener complaints?

Also, I find it most interesting several FM stations carrying NFL games are turning off HD because of the delay. Interesting trend there wouldn't you say?

Not really. There is a "sports flag" built into the HD spec so that radios fall to analog during sporting events.

So it's working as planned.
