iBiquity's IBOC System Dead?

V

vsa

Here's a provocative announcement on Leonard Kahn's website/blog. I know Kahn filed a lawsuit against iBiquity and others early this year.

http://www.wrathofkahn.org/

"10/3/2006 - On Opinion and Belief the iBOC System is Dead.

You know how we hate to brag, but Cam-D is the winner, as is the free marketplace.

Dear broadcaster, you are the real winner. You are now free to enter the twenty first century digital/analog world.

What happened? We cannot at this point say more."
 
Ummmm....how can it be "dead", with stations broadcasting it and radios available?

If someone tries to start a rival system now, well, just turn out the lights and let's all go work for XM.

But then again....didn't CBS sell color wheel TVs in the 50s...and we recovered from that! ;D
 
I noticed that Kahn used KDYL 1060 in Salt Lake City for his demonstration for CAM-D. That area has excellent groundwave propagation and KDYL is relatively free of co-channel and 1st ajacient interferers. My point is this: How would the CAM-D system work, for instance, on a graveyard station in a crowded area of the country?

Interesting point. I'd love to find out. I still think that like HDTV, we will end up with more than one standard for digital radio. These days FCC is run by political appointees, not engineers. I don't think they are capable of making any technical decisions based on sound engineering principles. I think that is really sad.
 
I would like to think Mr Kahn was able to finally make the engineering issues clear to the few engineers left at the FCC.
It is more likely that ibiquity et al have been conspiring to derail radio as we know it, and this is becoming openly evident in the courtroom as this case unfolds. This could be the only reason for the limited nature of the announcement.
As this was to be a jury trial, and I don't beleive the jurors would be sequestered in such a case, they must have heard about the recent reports regarding the FCC report that was suppressed. Hopefully the jury is angry at the FCC, and this couldn't come at a better time for Mr Kahn.

I will be only mildly sorry for those on the ibiquity train, if it is derailed. As with Enron, how could the people involved beleive
that it is an honest venture, to steal your neighbor's radio's usefulness, and then sell him one-half or third of the usefulness in a new service, which requires replacing every radio in use.. bedside, kitchen, basement, garage, living room, cars, etc. The new radios then won't do any of things I and many others expect of radio, and the new service stomps on its neighbors toes and inflicts the host signal with hiss?
If ibiquity truly beleives they are entitled to jam destructive interference into the public's airwaves, and that they're gonna "own"
the IP for access to electromagnetic propogation they are due for rude awakening. I hope they choke to death on their malicious patent.
Let us hope we can now proceed implementing the truly compatible system.


The AM flamethrowers and FM buzz will probably continue as long as the appeals process.
I listened to the CAM-D clips and sure would like to hear the real thing on a radio with wide IF bw.
I don't think the receiver used shows how good it probably does sound.

Congratulations to Mr Kahn for taking the bull by the horns.

"Digital Signals Spark Static From AM Radio"

http://online.wsj.com/public/articl...7Nti_dn3Fo_20070302.html?mod=tff_main_tff_top
 
Sorry in advance if this is the wrong section for these questions but... With all the hub-bub about HD stations, why is it that AM stations can only broadcast in HD during the day?? Will this change in the near future?? Also can FM's broadcast in HD 24 hours?? Seems to me that it wouldnt seem worth the $$ for buying a HD radio if one can only listen to it during the daylight hours. :-\
 
The FCC has not approved IBOC for nighttime use, because just like daytime AM/FM, it causes adjacent-channel interference, and at night, skywave propagation carries the interfence much further. Yes, I believe FM is 24/7. Save your money and get Satellite Radio, WiFi Radio, iRadio, etc...
 
Also because Industry Canada has objected to nightime..
