Digital FM without the adjacent channel noise!!

[SUPERCASTER]

Dear 1q2w3e and others,
Here is your quote:
"There are no CAMD radios. I personally talked to Leonard Kahn. I was seriously interested in what he had to say. But after talking to him, he seems more interested in muddying the waters than really creating a solution."
"No one that I know of has heard the CAMD digital signal yet."

My reply:
One of the new "software radios" might be a good start. They are software programable.

Leonard called me also. I agree with much of what he had o say, but I might approach the marketing, and public relations somewhat differently. But who knows, Leonard may be right!

OK, now what is the average person to do with this? I mean will this thing work in the car where the vast majority of radio listening is done? Can I send the link to my parents in Florida and have them ready to receive programing in a few minutes? For all the neagtives, as you say about IBOC, as of today a person can purchase a radio, plug it in and tune to a digital station. Are we anywhere near that stage for any of the competing systems? At least when Armstrong was transmitting on the old FM band there were off the shelf receivers available (And I am very much pro Armstrong and anti Sarnoff. Armstrong was without a doubt a genuine genious). The major (pun intended) problem we have today (and had with the AM strereo debacle) is that many of these competing systems do nothing but cause confusion and limit progress. I do believe that a world-wide standard should have been developed (and from what I've heard DRM isn't the answer to that) but from where we are today if we have four competing systems, people won't know what system to purchase and we'll see the AM stereo scenario all over again. That serves no one.

The world standard should not be adjacent channel, incompatible, expensive, complex, interfering, still awaiting final FCC approval, ibiqity HD Radio.

That serves no one.

That's iBiquity HD Radio. The system that serves no one but a handful of excessively greedy cartel members.

The ONLY reason you have IBOC instead of a better system is that the big boys feared that lesser stations might get a better signal. With Eureka, all digital stations are the same from the mighty 50kw to the lowly 250 watter. The big boys would have nothing to do with that. So, we have a Rube Goldberg system that may or may not work....

I tend to agree on this last point. Until now the implementation of digital radio in the US was not like the AM stereo debacle at all. Until now there was one system being implemented by both broadcasters and radio manufacturers. However, if some of these other systems start to gain traction, the whole thing could go the exact same route as AM stereo.

The most likely scenario is that Ibiquity will continue to dominate the field and will ultimately be declared the digital broadcasting standard for FM.
I don't believe Ibiquity will become the standard on AM unless it can fix the nighttime skywave interference problem. This is where Kahn's system might come in to play.

I also agree with your comments. There is a problem with AM IBOC not the least of which is the artifacts present in the audio. I could deal with the sidebands if the audio produced had no issues and of course nighttime operation is a big question and daytime only use is unrealistic. That said, Kahn and his supporters would be wise to consider not offending eveyone with their overstatements and insults. Of course anyone treated in such a mannor is going to respond using the same kind of language and nothing is acomplished when that happens. As to FM at least here in NYC there is no interefernce cause by IBOC operation to any listenable radio station.
