IOBC clearly violates FCC Rules and causes severe destructive interference.

[SayNoToIBOC]

"The Commission has also received engineering analysis, using widely different procedures, from a number of independent prestigious engineers, both domestic and foreign, all reaching the same conclusion; the iBiquity System clearly violates FCC Rules and causes severe destructive interference. And, most importantly, the FCC has now received a number of reports from Engineers and Station Owners reporting that the theoretical determined interference is REAL and is being suffered wherever the iBiquity IBOC system is on-the-air."

Fixed your fraudulent subject line.

Obviously only the FCC can rule that something clearly violates their rules, and they haven't.

Nice try, though. Another opinion piece!

what is IOBC?

IOBC is a system which it's neysayers have never actually heard. Maybe they're confusing IOBC with IBOC.

If it's the case that no FCC rules will be broken, why don't any AM HD Radio stations broadcast at night? CAM-D stations broadcast 24-hours-a-day without any FCC consent. None is needed because no rules are broken.

Maybe they'r whining about IOBC then. We should ask our host site to create an IOBC forum for them so we can discuss IBOC.

Hmm, well Mr Kahn CAM D is a technology which promises a lot but doesn't deliver a thing. No radios (They're coming. Yeh right) We can get rid of the analogue carrier (What did Dionne Warwick sing? Oh yea, Promises Promises). You left out that CAM D will work on FM too (They want to use the same system on AM & FM so don't give me the FMXtra nonesense). The indusrty has settled on IBOC (And that's the way it is) and manufacturers are gearing up. Why Tivoli will have a IBOC radio (With 2nd generation chip) within a month or two. Meanwhile no CAM D or FMXtra radios on the horizon. BUT, they're coming. Soon a radio that will do both systems, we'll calll it, Smoke & Mirrors. By the way, any major market stations transmitting in either Cam D or FMXtra?

That's the point. They don't run IBOC at night, because they believe that a rule may be broken. The rest of the time? No rules are broken. They may try to get a rule changed. Again, it being a free country, they have the right to do that, and the FCC may accomodate them.

NEVER MIND that they have stood the original rule that defined the 'spectral mask' a station must confine its emissions within to 'allow' the IBOC (in-band on-channel) over-the-air broadcast protocol to be broadcast.

Simply put, that 'rule' used to be the stick that an over-modulated AMer could be slammed with to get them to clean things up, regardless of any incidental interference that someone might complain of (like another broadcaster) and thereby provide the means for the offending station to clean up a bit more (REMMEBER, I prefaced this paragraph with the caveat "simply put").

Everybody seems to have conveinently FORGOTTEN this bit of technical and legal history.

Actually the NRSC mask wasn't put into place to smack the over-modulators. It was put into place due to the effects of trying to cram way too many stations on the AM band. At the time the AM band was a mess, and they needed a good, efficient way to clean it up without deleting licenses. By cramming AM emissions into the mask, it effectively reduced interference.

I wouldn't say it's been forgotten. In the discussions I've had about AM IBOC, it's been discussed quite a bit. Now, there's no saying that that rule couldn't be changes, for better or worse. Everyone speaks of the NRSC Mask as something that is written in stone, and can't be changed. I'm not advocating it, nor am I saying it's a good idea, I'm just saying that there is no reason that it couldn't be changed.
