IBOC - Redefining AM Radio Service As We Know It
For One and All,
IBOC - Redefining AM Radio As We Know It : To properly implement IBOC in the AM Radio Band both Day and Night would require that AM Radio Station Service in the USA be reclassified as a "Local Voice Media Service". Reduced - The Power of all Major Market AM Radio Stations down to 25 KW Day and 10 KW Night Fix - Regional AM Radio Stations at 10 KW Day and 5 KW Nights Allow - Local AM Radio Stations to be rated at 2.5 KW Day and 1 KW Nights. Low Power - Educational, Community and Translator AM Radio Stations limited to 250 Watts Day and 100 Watts Night. ok - so it's another stupid idea ~ RHF |

Which, for all practical purposes, it is. Night listening to AM is less than 2% of the population to start with. Night listening beyond the groundwave contour is restricted to a handful of stations as most US AMs have vastly reduced night coverage compared ot day coverage. So, there are very few listening to AM at night and very few stations capable of getting a skywave outside the local coverage area that is consistently listenable. The FCC has considered stations to be exclusively local for nearly 5 decades. Reduced - The Power of all Major Market AM Radio Stations down to 25 KW Day and 10 KW Night Wrong. In many larger cities, 50 kw is a minimu on anything but the lowest frequencies to cover the market and overcome the interference level of computers, dimmers, flourescents, and all manner of other man made interference. Your idea neglects the fact that different parts of the AM band have different coverage for the same power: 50 kw on 1600 covers less than 1 kw on 540. And it neglects the fact that different parts of the US have vastly different ground conductivity. 500 watts in Iowa covers better than 50 kw on Long Island. Fix - Regional AM Radio Stations at 10 KW Day and 5 KW Nights In LA, all but one 5 kw station (KLAC) does not cover the entire market day or night. Allow - Local AM Radio Stations to be rated at 2.5 KW Day and 1 KW Nights. Not enough to cover much of anything at the high end of the dial. Low Power - Educational, Community and Translator AM Radio Stations limited to 250 Watts Day and 100 Watts Night. 100 watts today is not usable 2 miles from the transmitter in, let's say, Florida, above 1200 on the dial. ok - so it's another stupid idea ~ RHF Agreed. |

IBOC - Redefining AM Radio Service As We Know It
IBOC will be just another failed attempt to "save" AM radio. AM radio died
decades ago as a viable medium. In 1985 I was in the industry and at that time CQUAM AM Stereo was gonna save AM Radio. It didn't and IBOC won't. In about five years we'll be listening to WIFI on our walkmans and car radio's. "RHF" wrote in message oups.com...

"IonSpot" wrote in message ... IBOC will be just another failed attempt to "save" AM radio. AM radio died decades ago as a viable medium. I see. then why are two of the top 3 billing stations in San Francisco AM? In fact, a quarter of the top 100 billing stations in the USA are AM. In 1985 I was in the industry and at that time CQUAM AM Stereo was gonna save AM Radio. It didn't and IBOC won't. AM swtereo was supposed to launch in 1978. A nasty old man, Leonard Kahn, sued to try to get his system approved, and it was 1983 before a decision was made. By that time, AM had gone form 60% of all listening to 40%, and there was no chance to revive it. Plus, the early C Quam was not a particularly good system, especially in cars. |

Rush Limbaugh and ethnic saved AM. Urban legend. Rush did not start generating big numbers until the early 90's. What saved AM was a combination of factors.... 1. Repeal of the Fairness Doctrine, allowing more agressive talk radio. 2. Several big companies, like Jacor, Clear Channel, ABC and Infinity supported news and talk on AM. 3. Most FMs, after programming deregulation in the 80's, dropped most news and content for music and entertainment. This allowed AMs to be unique in offering news and content. By the late 70's, the big Black stations were on FM. So this sector did not help AM. And Spanish language stations started moving to FM in the very early 90's, to the point that, as an example, today there are less than 2 shares of Spanish listening on AM in LA and 27 shares on FM. Hispanics don't use AM much at all, unless ther eis no alternative. Religious broadcasting did help make marginal AMs viable, though. The real issue is that a huge percentage of urban located AMs do not cover the entire market. Some were licensed before the suburban growth of the US after W.W. II, and others are just bad facilites. In washington DC, there is not one station that fully covers the entire metro on AM, for example. Interestingly the AMs with good signals have always been successful. |

Yep, BMW starting next year is the first. Ut till a few months (11/05) ago, there was no design spec for receivers, so that is why there are few today ant it will grow as we now have the second version of the spec, and furhter development is being done. I think you mat have already mentioned a brand but what would you recommend for a home radio. None. Wait 90 days for the spec. #2 receivers. |
