    We didn't have a TV till I was 11. I'd make a bed of blankets and pillows,
    with books, coloring books, and such around me in front of the big cabinet
    radio. Listen to the radio shows (some were later TV shows) Listen to the
    shortwave bands at night. Radio Free Europe and Radio Havana with it's
    on-going talk. People talking on shortwave, or in foreign countries (I
    couldn't understand).
    Do people still have shortwave and CB radios? Now with the internet, cell
    phones, smart phones, etc. Just thought of that.
    I'm surprised someone hasn't lectured us here about being OT (LOL)
    But, at least it's a good discussion and not mean-spirited. Well, maybe it
    is on-topic, about trolls.

  2. Carrie,

    We still have shortwave radio.
    CB radio is in the shorwave radio frequencies.

    The reason SW is popular is because the signal travels for miles.

    And bounces off the moon... the original communication satellite.

    Wrong!

    The signal bounces off the ionosphere, part of the upper atmosphere.
    The ionosphere is ionized by solar radiation, and it plays an important
    part in atmospheric electricity. It is practically important because
    it influences radio propagation around the Earth.
    It is also the reason those SW radio signals are effected with
    electrical noise (which most folks referred to as "static") and why
    phenomena such as "Sun spots" effect short wave transmission.
    It is also the reason for FM, and why it is so noise free as it uses a
    line of sight transmission completely avoiding the ionosphere.

    I liked the idea of them bouncing off the moon LOL

  6. Shes only 5% wrong :)

    It does bounce off the ionosphere like you correctly said.

    Every 7 years the sunspot cycles create havoc on certain RF ( Radio
    Frequencies )

    SW frequencies bouncing off the Moon is only 5% wrong?
    Please explain that logic.
    I think you should reevaluate your understanding of propagation of
    radio waves in the usual SW RF bandwidths. The Moon has no involvement
    at all with shortwave radio.
    I'm glad you agree.
    Yup!

    The effect of solar radiation on the ionosphere is also the reason
    shortwave reception is better at night.

  10. My Brother-in-law was a shortwave fanatic all his life. He had an
    antennae stretched over 100 yards over his farm, and shorter ones at odd
    angles. He used to bring us news that was shocking, some of it debatable
    as first-person.

    Four years ago he said that the Internet has taken over the same role,
    however just recently he said that short-wave has become the internet's
    undernet. Life has resumed its interesting communication.

    That is disingenuous of you, considering that I have been nothing but
    courteous in this discussion.

    When I have knowledge of a subject, be it an issue with Photoshop, or
    when I see somebody who has the wrong idea of a concept, such as that
    brought up in this sub-thread regarding SW RF propagation, I try to
    bring some clarity to the muddied information.
    When a statement is made and it is undoubtably wrong, I will challenge it.

    ....but if you would prefer to remain blissfully uninformed, who am I to
    intrude on your ignorance.

  12. Now, computing and amateur radio works together.

    Its called packet radio, and has been around for a long time.

    I have managed to speak to someone nearly 2000 miles away on a 1/4
    watt hand held, which was hard to believe at the time

    My uncle had a "radio shack" in his yard. Long time ago, when I was a child
    (and that was a long time ago), I didn't realize at the time he was involved
    in starting the first radio station in MA. It might be the first one in the
    country, but they had a fire in the 50's (the station) that burned a lot of
    the records so they can't prove it. I learned this when I inherted a lot of
    his pictures and papers, and got in touch with a radio historian, who was
    very interested in them, and I donated them. Though nothing in them could
    prove it WAS the first radion station in the country. Had info and stories
    about how they had to maintain the towers and actually climb up them to fix
    things. I don't understand all that, but to do with transmitting and
    frequencies, and such. Radio-electronics it might have been called.
    Hard to imagine what a big deal it was at the time. And being in touch like
    that. When I first got online and learned there was an instant message
    program called ICQ I realized that was from radio talk. C-Q looking for
    someone to talk to.
    Later, when I was in my teens/20's I had a short wave receiver and got into
    listening to the calls, and wanted to get a license and a transciever. I got
    to know some of the people who did, and was a SWL. I used to make attempts
    at learning morse code, which was required for the license (first step)
    Don't remember much, and never did learn to read/send it very fast.
    Makes one wonder what will be next, if the internet and cell phones, etc
    is like short wave and radio was "back then". I've read the some think the
    next step will be having communication devices implanted so we can
    communicate without having a computer, phone, etc.
    I used to love listening to people from around the country and world.

    Not long ago, I worked aboard the USS Battleship Missouri, a tourist destiny
    now. People are still communicating with morse code! I watched the radio
    operators a few times using the "vibroplex" to tap out their communications
    amazingly fast in a form of short-hand. There is a website where radio
    operators can punch in a call sign, and if listed, details about the
    destination is specified. Morse code is preferable in some cases as it is a
    universal language around the world.

  17. Yep True,

    I think skypes trying to take over the world ;-)

  18. In fact, amateur radio people invented the first proofed protocol called
    at the the, "aloha". Way before the internet.

    Okay, the ionosphere does reflect some radio waves back to Earth,
    but not all. Many amateur radio operators use moon bounce to send
    signals, but it's more of something to play with. You need a very
    high frequency transmitter and an antenna array to accomplish
    this....something along the lines of a helical array.
    The term ICQ means what it stands for...I seek you, just like in
    ham radio, the CQ means seek you.
    While amateur radio is still active around the world, there have
    been lots of changes in it. Now, with a walkie-talkie and using a
    duplex repeater, you can talk to other amateurs all over the world. (I
    once talked to a guy in Nagasaki, Japan and I was in passing through
    Maryland.)
    Ham operators were the ones to develop what is now the cell
    phone. Many years before we had cell phones, hams had touch tone pads
    on their walkie-talkies, and by punching in a three digit number, they
    were tied in to a phone line through a local radio club's repeater.
    Once they had a dial tone, they just punched in the phone number of
    whoever they wanted. When they were finished the call, they punched
    in one digit and the phone line was disconnected.
    As for Morse Code, this was a requirement to get your Ham
    license. The purpose of the goverment issuing ham licenses was so
    that if a war broke out, the government would have a source of trained
    radio operators that knew how to operate a radio station and could
    understand Morse Code. The reason they use Morse Code is because it
    takes up little bandwidth to send and that allows it to be sent
    further than voice communications.....especially when there is
    interference on the airwaves, either man made or naturally occuring.
    Morse Code will punch through when voice can't....even single
    sideband.

    (ps. I'm not a know-it-all, I've just been an amateur radio operator
    for 46 years.)

    Hey, fucktards. PHOTOSHOP. Take your douchebag radio conversations to an
    appropriate group.
