  1. Re:Hams on Web Access Over Power Lines · · Score: 2, Interesting

    A very valid statement. Not one that most hams are willing to accept ;-)

    But then, hams are pretty vocal about keeping the status quo. The FCC has issued a statement that they intend to remove the morse code requirement from all levels of ham radio licensing.

    It's a firestorm in the hams-on-Internet world, as some are extremely vocal (with very poor grammar) about keeping "the rif-raf" out with the hurdle of a morse code test for the HF bands. You'd think the sky was falling...

    The FCC is discussing what kinds of tasks show that one is able to safely and lawfully operate a radio. Meanwhile, some curmudgeons want their little hobby to remain "elite" in their minds and I suppose having it die out is about as "elite" as you can get, eh?

  2. Re:Hams on Web Access Over Power Lines · · Score: 5, Informative

    The opposition, even with the offer of notching the offending frequencies, is that the notches that have been demonstrated don't do enough.

    You could say it lessens the interference by 50% or so, and that's not enough because ANY increase in the "noise floor" (the background signal that exists on a frequency which a signal must overcome in order to be heard) makes it more difficult for ham radio operators to use the frequency spectrum that they are licensed to use.

    One solution would be for ham radio operators to just increase the power they use. Unfortunately, most hams operate (on HF anyway) at their full power capacity. Also many hams enjoy the challenge of low-power communications of 5W or less (worldwide communications are possible on under 5W).

    The principle of the thing is that why should a commercial venture be able to do the things that, so far, no one has been allowed to do: emit RF across such an immense spectrum of frequencies, including those for which others have what the FCC calls "primary" usage granted to them.

    The ARRL has said that they do support a Motorola solution because it does not add any interference to the ham radio frequencies. So not all BPL is bad. Ham radio operators are opposed to those that are bad.

    The argument thought that because of these ISM bands, we ought to throw out the whole FCC is what's crap.

    I agree 100%. It's the little pockets of limited anarchy (a paradox if I ever saw one) that is the ISM bands that allow this great innovation.

    It's just too bad that it's too popular for its own good. Watch the cheap, cool, products kill themselves.

    The ISM bands (Industrial-Scientific-Medical, blocks of frequencies in which the FCC does not require each transmitter to be licensed) were created to allow low-power telemetry-like radio systems for commercial use. The idea was that they would be limited to very low power and would likely be physically seperated by a long distance and so interference would be minimized. The FCC says that in these bands, if there is interference, it's your own problem: you cannot complain to anyone -- we gave up micromanaging this stuff.

    This is what things were like before the FCC. People transmitted where they wanted, at what power they wanted, etc. It quickly became clear that some coordination was needed, and the FCC is that coordinator.

    Most of the FCC's dealings involve licensed operations, where each transmitter (not manufacturer, though they have their own obligations to the FCC) must have a license and a responsible person operating the transmitter. Most consumers only interacted (before the boom) with these systems in the form of TV and Radio, and then only on the receiving end.

    It's those ISM bands where consumer-technology companies saw a huge opportunity because they could allow regular folks to use wireless technology without needing to mess with this individual licensing stuff.

    One might look at these ISM bands (900 Mhz, 2.4 GHz, 5.8 GHz, etc.) as little unregulated, free-range wireless playpens. The bands aren't that big, but technologies like spread spectrum have allowed much use to be had within the boundaries of the regulation.

    Unfortunately, now nearly all consumer wireless equipment operates in the ISM bands, and the interference-mitigating technologies are being pushed to their limits. Hence your telephone and 802.11 system do not always play along. It's not just them talking, it's all the other cordless phones and 802.11 devices, telemetry devices, etc.

    The mess that is the ISM bands was not the "existing reality" that the FCC was created to manage. They allowed the mess to occur in a controlled environment (away from licensed transmitters). We should thank the FCC for handling it this way, though we should also probably ask for some bigger ISM bands in the useful spectrum (900 MHz, 2.4 GHz). Unfortunately, almost every slice of radio-land is spoken for by something.

  5. Re:Its not a business on Another View of the FCC and Spectrum Scarcity · · Score: 1

    That's just handling of the licenses. Part of the license for public broadcast services (TV, radio) says that the broadcaster must abide by the rules of the license, including prohibiting (profanity|obscenity) from being transmitted.

    The FCC is just applying the prescribed remedy for violations of the pre-existing licenses.

    If you want the FCC to stop "enforcing clean language", then convince the broadcasters to re-negotiate their licenses so that they don't have such objectionable clauses. The FCC has the power to do that.

    When they issue a license, the licensee agrees to the conditions set forth in the license. It doesn't have anything to do with the FCC being the polite-police.

    The proper method to dealing with unwanted laws/regulations is not to stop enforcing them, it's to get rid of them and allow the enforcement to follow the law. If the country worked that way, abuses of infrequently-enforced laws/regulations would be less likely to happen, and when they did happen, would be easier to handle, since everything is based on the written law.

    (Yes, that won't happen. It takes away too much control from law enforcement, who enjoy the ability to charge alleged offenders of the law in whatever degree they prefer.)

    Fusion power plants have neither of these problems. They use water for fuel and produce material that isn't fissionable and is safe after about 50 years.

    Is it reasonable to compare current power-generation technologies to Fusion? The reason Fusion power plants don't have either of these problems is that there aren't any fusion power generation plants in existence!

    The chances are that once we do have viable fusion power generation, there may be a down-side or two. But we won't know these negative aspects, or even if there will be any negatives at all to Fusion power until we actually have it delivered.

    I guess that's just common sense, though.

    This is what is supposed to happen. All (nearly all?) sewage treatment plants have a bypass to send the input straight to the output, which is usually a river or lake.

    They do it because when a treatment plant cannot accept any more sewage, whether due to excessive water input by rain, or by power loss, the customers are better served by *NOT* letting the sewage back up into their houses. The stuff has to go *somewhere* when all their holding tanks are full. This is the last-resort method of dealing with problems at such plants.

    But the more I thought about it, the more clever it becomes. It forces people to think about...

    Which brings up a point which is both off-topic and unrelated to this story, you, or your post (so please don't take this as a personal attack):

    Consider the set of people who think it is clever or just "not wrong" to, as stated, force someone to think about something. Now consider the set of people who get upset and/or offended when someone "forces" them to think about a religious faith. (The reason I use the word "force" is because the commonly heard complaint in this area is that one's beliefs are being "crammed down the throat" of the offended.)

    For example, one argument about prayer in school or the phrase, "under God," in the U.S. pledge of allegiance is that the mere hearing of religious words has somehow tainted one's freedom to practice or not practice any kind of ritual or belief.

    Consider the intersection of those two sets of people. I wonder how large/small it is.
