CITADEL DUMPS NIGHTTIME IBOC

From Amateur Radio Newsline....this is just a snippet of the article.

RADIO TECHNOLOGY: CITADEL TURNS OFF IBOC

Citing many complaints from listeners, Citadel Broadcasting, the parent
company of ABC Radio network, has instructed all 10 of it's A-M
affiliates who had already converted to In Band On Channel or IBOC
digital, to cease night time use of the modulation scheme.

We can only hope this is the end of IBUZ....and maybe something better willl come along.

It already has, by way of Leonard Kahn's CAM-D technology. Alas the FCC is listening only to Ibiquity (and probably Ibiquity's legal team). Kahn had a great AM Stereo product, but Motorola's lawyers silenced him.

What a damn shame.

Leonard's big mouth and his own ego killed his ideas...CAM-D is NOTHING....have you listened to it?? I have....all it does is carry the higher freq components in the digital stream..other than that, its still analog AM with snap, crackle and pop!
His AM stereo ?? well I was a fan of it....but he never sold or licensed decoders for it....STUPID!!! And it did have issues...poor sep above 5 kHz and if the tower reactance wasnt flat across, one sideband had better freq response than the other....thus level offsets in L and R........could have been fixed with the same techniques needed for AM IBOC bandwidth.....

Personally I like Radio Mondale.........but it doesnt seem to be getting attention in the US as long as IBQ is paying the FCC.
 
Radio MONDALE?? HAHAHAHAHAHA...that's hilarious!!! ;D :D :) I think it's actually "Mondiale" instead. I guess Radio Mondale would be big in Minnesota, especially amongst the Democrats who supported Carter and who liked the idea of a woman vice-president. (or are we talking Eleanor Mondale here?)

I agree on your assessment of Kahn. Naysayers jumped on his flakiness long ago and wrote him off as an idiot. His ideas are never taken seriously anymore. Sad, as I think there was something there with his AM Stereo. All I've heard about CAM-D is that it's a rehash (sorry for the pun) of his AM Stereo idea. I've heard Europe's Eureka 147 model is the best, hands down. Problem with it, is that it doesn't have the benefit of lobbyists or Ibiquity pounding the FCC and Congress to get it approved.

Well at this point you can have either I-BUZZ or CAM-D. Which one is the lesser of two evils?

Wondered if anyone would notice the typo and play on the name ;)
Glad it got a chuckle for ya........hehehehe

CAM-D acutally is more like PowerSide (which IS and ISNT Independant sideband like his AM Stereo)....In Powerside, one sideband has more energy than the other...the undesired sideband is basically down to a min...all you need is one sideband and carrier for an envelope detector to work)....In CAM-D, the unused sideband is fed with the digital info instead...
ALL this is similar to his AM Stereo....but no stereo pilot and one sideband is fed L+R, not just L or R.....BTW Powerside DOES work and can reduce adj channel issues...since you now reduce bandwidth from 20kHz down to 10 kHz of the actual transmitted signal...by concentrating all the audio into one sideband, the reactance curve of a directional array can be used to the best side...thus producing the best audio response...except the rcvrs are crap!

Neither or both.....CAM-D can give you better MONO audio but it is analog....IBUZZ can give you stereo and digital audio but at the cost of adj channel trashing...Analog AM is still a useful mode since it is EASIEST to receive....but it is the worst in reception due to noise issues....No consumer radios ever had a Noise Blanker added to help..The only decent bandwidth receivers were those for AM stereo...like my Sony XRA-33...which had a selectable wide/narrow filter....even in mono mode..NOW THAT worked nice when in range of a blowtorch of a signal where I could go wide and WOW....it was FM quality audio....(Listening to KKBQ AM&FM in Houston back in the 80s with Kahn AM stereo on 790 was better sounding to me than the FM!! Go figure)

CamD has a problem that it has an analog base and digital implants to convey the high frequency and stereo data. It is not immune to static, and man made interference, one of the big problems facing AM. It's not a true digital age solution.

Receiver manuafacturers will never spend a cent to enhance AM reception, as they perceive most of the consumer market has no interest in AM, and they are right. So a system that requires separate design and components will never have a chance.
 
Well I don't know about the rest of you, but I like hearing signal breakup on the AM dial! Give me those cracklin' noises when mother nature is dishing out storms full force! :D

Guess this makes me a grumpy old man?
