What is the reason that you are so ticked off about HD/IBOC? Your many negative posts make me think it is somehow personal.
A lot of people are ticked off because it is jamming both bands with adjacent channel interference. It is a thinly veiled attempt to jam smaller broadcasters and rim shots right off the dial. Once in a while an advocate actually slips up and states that plainly.
It is a "fix" to something that wasn't broken - the sound of radios. Fixes to the sound quality have been around for decades - AMax, diversity antennas, stereo blending, etc. FM could also adopt the Canadian equalization curve and sound MUCH better - I've heard 20 Hz to 18 kHz on some Canadian stations. Broadcast radio is in trouble due to competition from satellite and iPods. The problem is bland formats approved by corporate legal - and people want none of them. I don't know how many times I've heard a local DJ say "I can't say that, the legal department wouldn't like it." Or "I have to get that approved through the head office in New York." Fix that problem, radio will get listeners back.
The whole thing sounds like high pressure (brainwashing) sales pitches. I can almost reconstruct the sales pitch stations must be getting - a lot of advocates sound like they have been cloned, spouting out the same words over and over again like invasion of the body snatchers or something. It freaks me out a bit - what's in that coffee the IBOC sales people undoubted serve station owners and engineers. Any attempt to criticize the technology based on sound engineering is met with anger, arrogance, and denial. This is a sure sign that Ibiquity knew from the start it was going to be an uphill battle, there was something inherently wrong with the technology (it jams adjacents), and they needed high pressure brainwashing sales techniques to sell it.
It ignores existing AM listeners by making AM sound horrific on all existing radios - which accounts for 99.99% of the audience right now. And any attempt to prove that is met by denial - no matter how many radios I buy and do an engineering tear down of to prove my point that virually all new designs are subject to IBOC self jamming noise, I am met by the same arrogant denial I just talked about above. Get used to it - all new AM radio designs are wideband because of their cheap IF design and sound like a waterfall mixed with a million angry crickets when you tune an HD station!
It ignores the interests of perhaps hundreds of thousands of NPR listeners on the East coast, who are listening to first adjacents in tightly packed metro areas. There are account after account of people being disenfranchised from listening to a public radio station because of IBOC on a station slightly closer. Not everybody lives under a tower, and metro areas of the East often are closely spaced, people living out in suburbs are equidistant from two or more city centers. All I get from arrogant IBOC advocates is the nonsensical statement "you were never supposed to listen to first adjacents". Yeah - with 1940's technology. And in THEIR dreams, you ought to be listening to their glorious station(s) instead of a first adjacent. To them, legalized jamming is a good thing. The reality of the technology is that now, with adaptive IF, listening to first adjacents is easy - commonplace. If broadcasters were smart, they would be lobbying right now to lower the spacing requirements so they could put more stations on the air (that they would own), and make more money.
HD-2 is going to become pay-per-listen - the technology is out there, it was demonstrated, and the chance to rake money in from niche audiences is too tempting to pass up, especially when ad revenue is falling. Good luck with that ---- personally I think it will backfire and drive even more defections to satellite. But why the pretense that HD radio will always be "free" - when the technology to make it subscription is already being announced? We KNOW its all about money, at least do us the favor of announcing it.
Some of us "outmodes" who DX are working over time trying to help a new generation of DX'ers, some only 12 to 15 miles from towers, get enough signal into HD radios to get reliable decode. We see the folly of a system that forces consumers to do something it has been proved they will NOT do - become antenna tinkerers. A percentage might tinker with antennas for a format. But the system is defective when it doesn't work with internal antennas - which for decades have been adequate for local stations. You want to attract younger audiences who are always "on the go"? MAKE IT WORK, the first time out of the box. Box open - radio on table top - turn on - HD with no hassles. Or else: market failure!!!
Put something on HD-2 people care to hear. Not clunkers like Spanish top 40, pride (gay) radio, all Beatles, etc. You program to tiny niche audiences like that, nobody will buy a radio for it.
