    Sorry, I am now extremely interested and frustrated about how the
    wristwatch can be so tiny yet receive so long-wave signals.

    Just how does such a magical device work? It seems to defy laws of
    science that such a small device can operate at such long-wavelengths
    of radio waves.

    I suspect it's probably something those FBI/CIA bastards are going to
    keep secret from us.

    Sick government f---scums. USA citizens should turn against the FBI/
    CIA and molest the f---ing s--- out of their colons using bubbas' c--

    I want to know how such a tiny device can operate at such a long
    wavelength. Unfortunately, that info is classified by the FBI/CIA, and
    then won't let me or any USA citizen find out about it.

    I am getting so pissed off right now.

    I am so interested in this wristwatch question yet I am so angry about
    it because the FBI/CIA won't let me know about it.

    F--k the CIA/FBI, may they be raped by big bubbas.

    No offense but please respond with reasonable answers & keep out the
    jokes, off-topic nonsense, taunts, insults, and trivializations. I am
    really interested in this.

    Have you ever seen a portable AM radio, e.g. a Walkman?

    Normally they can coil the aerial inside the device either as a real
    coil or on an IC. This takes a lot of space however.

    $DEITY, man, get a grip on yourself, OK? This is *old* technology - a
    similar method has been used in AM radios for decades, dating to back
    before the transistor was invented. There is nothing at all tricky,
    or hidden/concealed about it.
    So, go "back to the source" just as the previous poster did.

    A quick Google on the phrase "wwv watch antenna ferrite" turns up, as
    its very first alternative, the following:

    which is a very nice overview of radio controlled clocks, courtesy of
    the United States Government (specifically, the National Institute of
    Standards and Technology).

    On Page 11 you'll see a clear photo of the sort of antenna used in a
    WWVB-capable desk clock. It's a standard ferrite loop antenna.

    On the following page you'll see a photo of the innards of a
    WWVB-capable watch. It has a similar (although smaller)
    ferrite-loaded loop antenna.

    If you go to you'll find
    the web site (with data sheets) for WWVB receiver chips. Download the
    MAS9180 data sheet. You'll see schematics, which show how a
    ferrite-loaded antenna is combined with a capacitor, creating a
    resonant circuit tuned to the 60 kHz (or whatever) radio signal.

    The trick is fundamentally no different that the one used in an
    ordinary battery-powered AM broadcast radio, which (in the older
    designs) uses a ferrite-core multi-turn loop antenna, tuned to
    resonate at AM broadcast frequencies using a variable capacitor
    (typically a 365 pF maximum). The WWVB frequency is about 10% that of
    signals at the low end of the AM broadcast band, so it's necessary to
    use a larger-value capacitor to tune any given amount of ferrite
    antenna inductance to the desired frequency, but it's the same method.

    As to how it works... well, think of it this way (and this is just an
    approximation). The high magnetic permeability of the ferrite acts as
    a sort of "concentrator", so that more of the transmitted EM field
    flows through the antenna than would be the case if the antenna had an
    air or plastic core. And, the large number of turns of wire on the
    antenna both increases the amount of signal produced by the EM field,
    and adds enough inductance that it's possible to tune the antenna to
    resonance with a reasonable-sized capacitor.

    Google on "small loop antennas" for more background.

    In the thread where I talk about analog cell phones using AM radio
    between 40 KHz - 285Khz, responders told me that it is impractical
    because the receiver would need to be too big to be portable.

    Then the topic of how wrist-watches can receiver long-wave while still
    being so small began.
    seemed that there just wasn't any explanation as to how wrist-watches
    could operate in long-wave.

    Usually with weird gadgetry like this, I tend to believe someone [or a
    lot of someones] is/are attempting to cover up a new type of
    technology that somehow exists and functions despite defying
    conventional laws of science.

    I then get extremely curious, jealous, and angry and want to forcibly
    get information as to how it is possible for that device to work. I
    want to torture the designers -- who I believe are the CIA/FBI -- into
    providing me the information. Its only human nature to be interested
    in things that seem too good to be true yet are still possible and
    existing with full functionality.

    I start to believe only the CIA/FBI could be doing something like this
    because they are the smartest and most evil bastards in the universe.
    Cold-hearted CIA f-kfoams.

    I get the feeling that the exploitative sadistic CIA/FBI know about
    science that ordinary USA citizens are not allowed to know about.

    I then want the CIA/FBI to suffer for what I perceive as their


    So I guess it is possible to have analog AM cell phones operating
    between 40 KHz and 285 KHz that are the same small size as today's
    cell phones. Right? If it's not possible then why not? If a wrist
    watch can do it, then why not a cell phone?

    Actually, this thread or logic reminds me of a redneck wanting me to
    connect his 40 watt car stereo amplifier to his CB radio 30 years ago.

    Actually, most likely, the reason these work, is
    because you (and most people) live under the
    Biggest Long-Wave Antenna around (Power lines,
    telephone cables, TV cables, ect)! And, those
    that doubt, tell me the range with a lousy
    antenna, that Jim Creek, and Ect. can be copied!
    this is around 18 KHz ! Corse, doent hurt
    to have a massive antenna, and beaucoup power
    ! BTW, THAT signal is also used to sync
    generators on the Power Grid (wonder what
    would happen in a power co got even 1%
    out of phase? Answer: Meltdown! Jim NN7K

  12. Oh, miniaturization is easy. I prefer the laundry method. Throw the
    laundry into the washer, add boiling water, and everything shrinks. Do
    it often enough and your clothes become miniaturized. It's the same
    way with electronics. Boil the watch in water and it will shrink.
    Try it.

    You can also manipulate the waves. Long waves are nothing more than
    short waves, that have been passed through a medium that slows them
    down (e.g. slow glass). Slow down the short waves enough, and they
    become long waves. So, the WWVB watch is really working with
    stretched short waves.

    There are other methods of component and size reduction. For example,
    simply leaving the watch in an exposed location will often make it
    disappear completely, the ultimate form of miniaturization.
    It works quite well. If it didn't, there's always the limited
    Yeah, that's a problem. Breaking the laws of science is quite common
    and generally accepted. Just watch any action movie and see how many
    physical laws are broken. If you defy a huge number of physical laws,
    it's called science fiction. The problem is that there is no physics
    police to enforce the laws and apply appropriate penalties to the
    violators. The last time that was tried was during the Inquisition.
    It failed. I wouldn't worry about defying the laws of science as it's
    unlikely that you'll serve any time or pay any fines.
    It's secret for your own safety and welfare. Were you to be properly
    educated, informed, and receive a diploma at public expense, I suspect
    the required effort and cost would bankrupt the country. Therefore,
    keeping you ignorant is economically justifiable. Try not to take it
    Well, I guess it's safe to tell you. Please don't redistribute the
    arcane knowledge to the GUM (great unwashed masses).

    The WWVB watch is not really miniaturized. The greater bulk of the
    circuitry is hidden in another dimension. String theory postulates 10
    or 11 dimensions, so there are plenty of spare places (branes) to hide
    bulky and awkward circuitry. What you're carrying on your wrist is
    only a small part of the receiver, as the rest is invisible. I hope
    this helps.
    Off? I don't think it would help if you tried getting pissed on.
    Yeah, that's a problem when the government controls your brane.

  13. All this for 245kHz of band space in a frequency area of high noise and
    long propagation paths.

    Engineering would dictate looking elsewhere.

    But hey, you want to try, go ahead. I believe there are allocations in
    the above spectrum for transmitting a couple watts into a antenna less
    than three feet long. I would think a wrist watch transmitter would qualify.

    Google up VLF, melt some solder, and let us know how you do.

    WWVB stands for W's World Vengeance Bureau

    Giving, so-called, accurate time is a trick to get people to wear WWVB
    watches and have WWVB clocks in their homes.

    They are actually AMPLIFIERS and REPEATERS! They amplify and repeat the
    hidden embedded mind-control signal that originates from Bush's Hurricane
    and Earthquake Machine.

  19. Well, it's not exactly a conspiracy, but it's close. The problems
    caused by excessive radio clock accuracy are quite serious. After
    all, time is natures way of keeping everything from happening at once.
    That's exactly what's happening when everyone carries an accurate time
    piece. Instead of a random timing of events caused mainly by the wide
    variations in older mechanical and power line sync clocks, we how have
    nanosecond accuracy on our wrists. Instead of a wide dispersion of
    event timing, such as arriving late to work, we have everyone arriving
    at exactly the same time. This has resulted in parking lot crunch,
    the packing of the elevators, collisions in the doorways, and instant
    depletion of the office coffee dispenser. This is repeated at
    quitting time, when everyone leaves at the exact same nanosecond.

    The obvious solution is to reduce the accuracy of WWVB or introduce a
    random dither (selective availability?) into the watch timing. Time
    accuracy will vary a few minutes one way or the other, and the peak
    load on the facilities will be reduced and dispersed over a wider time

    Chris, the antenna used in wrist watches can only be used to store
    Since the antenna is based on superconductors the watch has to be
    cooled to a extremely low temperature
    before the data becomes accessable.That method has not been made
    public outside the military.
    One can consider the analogy of cold weather antennas generally known
    where under certain environmental conditions transmission can be
    stored, and with the onset of warm weather ice particles in the shape
    of dots and dashes gradually emerge in data form so the transmission
    can be decoded.
    If you wash your arms and hands with your watch strapped on then time
    is on your side as decoding is near impossible.
