''...a draft Report and Order to allow all U.S. AM
stations to use HD Radio at night is reportedly sitting on the FCC Chairman's desk. Insiders say the document will allow all stations (with equipment in place) to light up simultaneously. Hopefully an interference resolution mechanism is included in the paperwork. Broadcast engineers surveyed on the floor of the NAB were not optimistic about the long-term prospects of AM HD at night, but iBiquity investors will undoubtedly make a concerted effort to make it work.''

[...] ACCORDING TO V-News.org Editor-in-Chief Kevin Alfred Strom, IBOC is an inferior, interference-prone system designed primarily to ensure the dominance of the corporate broadcast media and limit or prevent the rise of new, independent voices on the radio dial. He states: 'IBOC (In-Band On-Channel) digital -- AM or FM -- is essentially a turkey, technically. It's inferior in almost every way to a dedicated digital system in a dedicated digital band. 'The main reason IBOC is promoted is because a new dedicated digital band would level the playing field: the present 250-Watt AM daytimer, once ensconced in the new band, would have just as clear and clean a signal as the 50-Kw clear channel or the high-power FM -- just as good fidelity, the same coverage, and 24-hour operation. Just as your Web site is equally clear and accessible as NBC's. 'A dedicated digital band might also be scalable and allow many more channels for the listener -- hundreds, thousands perhaps. Probably enough to allow public access (in which anyone can be a broadcaster for free or nearly free) on an even greater scale than does cable television. 'And that would mean more competition for the big-money men. 'And it would mean that competition would now be purely on the basis of programming, not the sheer signal superiority which the money-men have paid for. 'They want to preserve the _inferiority_ of their smaller competitors. IBOC does that. They want to maintain the high economic hurdle to becoming a broadcaster. IBOC does that.' |

This is as it should be. AM stations will never discover or correct nighttime IBUZ interference until they can hear it. Daytime only use of IBUZ won't work. The quality difference between AM analog and digital is more dramatic than FM, especially when loudness wars are likely to continue and the alleged quality improvement will get lost in the dust. The real advantage of the FM system isn't improved quality, it's secondary channels that will compete with their main channels for ad dollars. In 3006 when there are enough receivers to make a difference, listeners won't tolerate the dramatic drop in audio quality. That would, effectively, make all AMs using the system daytimers as listeners tune away when muddy analog comes back at 6pm.. Now is the time for stations to do whatever rebuilds they need rather than waiting until everyone has to do it at the same time. I've proposed that the first stations to make the required transmitter plant improvements be granted priority over others that might interfere with them. No station should have to modify its plant multiple times as adjacents light up. Rich |

3006? Huh?

You all may think Rich is a bit off-the-wall about urging 24-hour AM
HD _RIGHT NOW_, but why sit around and agonize? Turn it on and the squeaking wheel of night interference will either get fixed or hybrid mode AM HD will be proven unworkable. But the situation needs resolving as soon as possible. Waiting for the laws of physics to change is misguided. bob c. |
