I disagree to a point.If DAB (digital audio broadcasting) were to catch on in Canada, AM and FM would have been on par. That's what AM may need in Buffalo.
The ability to be on par with FM and the freedom to flick a switch on the radio that makes AM sound AM, or FM if the listener chooses to have either sound for their choice of (mainly classic?) music.
Yezi, there are a lot of folks in the biz in the States who believe the Canadians and CRTC had the right idea by allocating a portion of the AM band to DAB so as not to cause interference with stations on co-channel frequencies near and far.
IMHO, AM will never be on par with FM as far as technical capabities, for any number of reasons, bandwidth and interference being foremost, emerging Internet technologies being the other threats. AM HD or DAB (call it what we will) isn't a panacea, it's a ruse (as I believe FM HD is), which I equate with what happened years ago with AM Stereo.
BTW, there are many engineers who strongly supported the benefits of AM Stereo, but felt strongly that the FCC should have stepped in and decided on ONE particular AM Stereo standard, as it did with FM Stereo many years earlier.
The FCC failed to make a decision as it was concerned about the potential of anti-trust litigation which might have been filed by companies which were not chosen as the "standard." The FCC held the opinion that such litigation would have held up the AM Stereo decision making process and hurt AM broadcasters and as a government agency, did not want to be caught in the middle of such litigation.
As it turned out, broadcasters were left to guess which AM Stero system worked best, and in casino-like fashion, placed their bets on the standard they felt would win the AM Stereo war and the public's preference. As it turned out, this lead to consumer chaos and many companies lost large amounts of money "betting on the wrong" AM Stereo process.
Although iBiquity has been chosen as the standard, I think AM HD is doomed and FM HD isn't far behind. I'm no Luddite, I just feel history can teach us some very important lessons.
Just my buck tree eighty.
