does the fairness
doctrine have any effect on the viewer? The Fairness Doctrine no longer exists. Reagan Administration. First Time Users May Be asked To Do A 1 Time Setup. "Bob Haberkost" wrote in message ... "Frank Dresser" wrote in message ... "Doug Smith W9WI" wrote in message ... It's commonly not understood by non-engineers that a radio station (broadcasting or otherwise) causes interference over a much wider area than it provides service. This is especially true on AM where multiple signals on the same frequency mix together. The open frequencies I mentioned aren't silent, but are a mish-mash of low power signals. They aren't useful in this area. Then they're not "open". And adding another signal, even a low power one, in this space would then interfere with the otherwise serviceable coverage closer in to these stations. The new Chicago X-band station moved from downstate - Johnson City IIRC. A station on that frequency in Chicago would not have been allowed if WRLL had been operating downstate. I live within 15 miles of WRLL, and it's almost unlistenable at night after they drop power to 1 kW. Skywave comes in from all over. A much larger number of daytimers could be worked out, however. That doesn't make the area unserved by WRLL's nighttime pattern "open". A facility allowed to fill in this "unserved" area would interfere with the stations whose skywaves come in from all over. And the FCC no longer licenses daytimers, and all attempts to apply for one will be rejected on this criteria. As it is, the FCC is looking for daytimers below 1600 (and encourages, through policies in place) to move to the X-band, in order to clear out the congestion and permit more regional service by the full-time stations on those frequencies. That's the point. The allowable amount of interference isn't really a technical consideration. At one extreme, we could have a very small number of true clear channel stations. Or we could have super saturated radio markets in which the only clear reception would be within the shadow of the station's antenna. Allowable interference is a political consideration, not a technical one. Actually, no. The interference standards provide for usable coverages to the limits of receivers (very few radios will provide a listenable output at 500uV, the current protection limit for nighttime service, which affords a 26dB signal to noise ratio, give-or-take). But protecting out to that limit means that for every 20dB increase in signal strength for the desired station (by moving closer to the transmitter) also means at least a 20dB boost in the signal to noise ratio...thus, the rural-grade 5mV/m contour would be a listenable signal. Allowing increased interference (by raising the protected contour to, say, 2mV/m) means that a listenable signal would be obtained at the 20mVm contour....which is a metro-grade signal-strength. So, in the interest of expanding coverage, you'd actually be reducing it. For both the new, as well as the existing, stations. All the details about how this is done can be found at http://kauko.hallikainen.org/FCC/FccRules/2003/73/182/ and http://kauko.hallikainen.org/FCC/FccRules/2003/73/37/ IMHO the FCC has grounds to regulate both services on content if they chose to do so. IMHO they need to either do so, or lift content regulations on OTA. Maybe so....but, for the former proposal, would you want a situation where the FCC can delve into the private affairs of these operations? You know, the next step would be censoring telephone conversations, as the analogy holds. Subscription services, and other non-broadcasting licensees, are not public entities. Better that if the FCC feels obliged to limit what can be said on OTA, they feel that it's the only area where such pervue exists. While I'm not so keen to remove those restrictions on OTA, the Canadians and other democracies have no such limits (although there's some discretion in how often the ability to say anything is exploited) and they haven't come to the end of the world. -- -------------------------------------------------------------------------- --- If there's nothing that offends you in your community, then you know you're not living in a free society.
