    greetings all

    I was wondering if there is any type of receiver I can find/purchase that would be
    capable of tuning above the FM band, like from say 100 to 130 MHz. In this range I
    would still want to be able to receive and demodulate FM signals (not the AM signals
    of the aircraft band), but not necessarily to go so high as to be in the 2 meter ham
    band. I've been looking all over the web but haven't found any receiver like this.
    Does such an animal exist, or would I have to retune a standard FM band radio for
    this job? Any advice/feedback/comments much appreciated.

    Why would you want to receive and demodulate FM signals in that frequency
    range? It appears that you may be wanting to transmit signals in that
    frequency band. If so, don't. You should not mess around in the aircraft band
    at all. Just because you can't hear a signal, doesn't mean the frequency isn't
    in use.

    If this isn't correct, what is your plan?

    There are receivers able to function with AM and FM in that frequency range.

    I have several transmitters around my house that transmit in this range. It's an
    experiment in creating an electronic proximity net. The transmitter outputs are
    < 5mW. What receivers do you know of (hopefully not much $$) that will receive in
    this range? Thanks.

  4. The freqs from 109 MHz up to the 144 MHz ham band are all used by
    aircraft for both navigation and communication. In the U.S.
    unauthorized transmitting on these freqs is a real big NO-NO, and will
    cause the FCC to jump on you like flies on dog doo-doo. If you're going
    to screw around with low power RF, do it in the low part of the FM BC
    band, 88 to 92 MHx, or the 82 to 88 MHZ TV channel 6 if it's not used in
    your area. If TV Ch 6 is used, then Ch 5 should be free. And there is
    also the band for radio control of toys somewhere in the 72 to 76 MHz
    band.

    Unless you're someplace like Escondido. LA has 2, 4, 5, 7, 9, 11, and 13,
    and San Diego has 6 and 8 that I know of, and probably 10 and 12.

    Good Luck!

    Don't forget that 75MHz is used for marker beacons on aircraft Instrument
    Landing Systems.

    Playing around between 108 and 136MHz is a sure way to get into serious
    trouble - probably even make the news media when you get arrested.

    Steve,

    That is "you're" not "your." As in - you're a dipshit, Steve.

    I'm sure you mean well. But get a life!

    Usage defines correctness, and it is in very common use!
     
  13. The english language is still strongly dominated by people who have
    english as their native language, but that will soon change.

    English will become the international language, and will change in
    that process. It will be simplified, and special expressions will not
    work in an international environment.

    Greece was the dominating world power when chemistry was founded,
    and we still see greek terminology in the field of chemistry.

    Rome was the dominating world power when medicine was developed,
    that is why latin is the language of medicine.

    USA/Britain was the dominating world power in the era of electronics,
    and in the era when the need for a common international language became
    very strong, so english is the language of electronics and the international
    language for the future.

    The language english will be reformed in this process, simplified and
    cleansed from strange expressions which americans use today.

    English is no longer the property of americans/brits, it is now the property
    of the world, and we will change it to suit our purposes.

    Common use or not, the use of "you're" for "your" is *ABSOLUTELY,
    TOTALLY, COMPLETELY WRONG*. It's a lovely barometer for how piss-poor
    our educational system is here in the US, but it's still *WRONG*.

    English is the language for the future because it's already been been
    so changed by other languages that it would be difficult to find
    another language more readily adaptable to change yet so readily
    understood everywhere in the world.

    You're a fucking idiot. English has never been and never will be
    "cleansed", and the only reason you think some of the expressions we
    use are strange is because you're so provincial you can't or don't
    want to see the reason or the humor behind the expression. Which
    expression(s) did you have in mind, anyway?

    Not only a fucking idiot, but an envious, pompous little bitch as
    well, huh?

    English never has been our "property", it never will be, and by being
    used it'll evolve all by itself with or without the help of goons like
    you who'd like to think your "edicts" will have anything to do with
    its evolution.

    ISTM that you need to learn how to be grateful for the gifts that
    you've received instead of begrudging where they came from.

    Actually your wrong, you just can't admit it!
    Pitiful attempted insult aside, you ARE acting childishly!
    Stamp foot and cry loudly. No one cares!

    I somehow doubt it. you will adopt the current state of English as
    devoured by your poor and huddled masses as directed by our popular
    culture. We will tell *you* what to (and how to ) think!
     
  18. French used to be a contender. It appears to me that French lost ground
    due to France being in some way hostile to the Internet back in the early
    and mid 1990's.

    The way I remember things, I saw sometime around 1995 a map of the world
    with the nations being color coded by some measure of how established the
    Internet was. France had the lowest color, same as most nations of
    Africa. France looked like a hole in cut out of western Europe on that
    map.

    A major reason was, if I remember correctly, France being hostile to
    privacy of electronic communications to such an extent that one had to
    have a license for a modem.

  19. The native english speaking world has had a strong influence for many
    years and still does. But the number of non-english people who use
    english is steadily rising, and there are 5.5 billion more people to come.

    I have seen how the situation has evolved over the last decade.
    In the beginning I was very alone among loads of americans and a few
    brits. Today the non-native english speaking participation in many
    newsgroups is around 25 percent, and it is growing.

    I predict, based on the current tendency, that the situation will be
    50/50 within 2 years, and after that the native english-speaking will be
    in a quickly shrinking minority. And they will have to think about how
    they speak english to be fully understood by the majority of the
    participators.

    The production of movies and tv-shows was totally dominated by americans
    between 1945 and now, but now we see how the rest of the world is
    producing more and more programs and movies. The american dominance of
    the world's media channels is quickly disappearing.

    scary! the iinternet may be the leakage path whereby the sum total of
