• 73! Morse telegraph ;)

    From Alexander Koryagin@2:221/6 to All on Wed Mar 3 13:24:06 2021
    Hi, All!

    Morse's code consists of letters, digits and punctuation marks. But punctuation marks are rather exotic Morse codes and many people don't use them. For instance, when I lived in the USSR, I could receive a telegram that looked like this:

    Great wishes for birthday ZPT hope you are well ZPT see you soon TCHK

    ZPT and TCHK are Russian abbreviation (written in Latin letters here) for a comma and full stop. Did you have in old times something similar when a postman brought you (paper) telegrams?

    I think it is not necessary to remind you that a paper telegram is a postcard with telegram lines glued on it.

    Bye, All!

    Wrong -- Morse code comprises but two symbols: the dot and
    the dash. It is a binary code.

    marks.

    Wrong -- Morse code comprises but two symbols: the dot and
    ??the dash. It is a binary code.

    First, it is not a binary code, BTW, I tell you as a programmer. Second, why it is wrong to say that, for instance, a language consists of words? Should I say it consists of letters?

    Bye, Anton!

    Wrong -- Morse code comprises but two symbols: the dot
    and the dash. It is a binary code.

    First, it is not a binary code, BTW, I tell you as a
    programmer.

    Can you explain to me why Morse code is not binary?

    Second, why it is wrong to say that, for instance, a
    language consists of words?

    Because in addition to words language has high-level struc-
    ture, i.e. grammar and syntax.

    Should I say it consists of letters?

    No. Even words do not consist of letters, because they ex-
    isted before writing was invented.

    When you write a Morse text you need three symbols -- the third symbol
    is needed to divide letters from each other. It is a ternary code. In
    binary code it is not necessary because every byte has 8 bits.

    Without a special signal all the Morse dots/dashes will merge into a continuous stream. So, a pause in Morse code is also a signal. We have short beep, long beep, and a long pause.

    Just for fun, we can invent a coding system using pause signals. For instance,

    A short beep - is a separator

    Between separators can be:
    one second pause implies 1
    two seconds pause implies 2
    three seconds pause implies 3
    ....
    nine seconds pause implies 9
    ten seconds pause implies 0

    And we have very a silent variant of "Morse" code for digits transfer. ;-)

    https://cs.stackexchange.com/questions/39920/is-morse-code-binary-ternary-or-quinary

    IMHO it is writen too much there on a simple subject.

    Can you explain to me why Morse code is not binary?

    in my mind, it is only binary because it has two symbols used in various patterns... however, silence is also a symbol, isn't it?

    the main reason why i see morse code as not binary is because it is not in sequential order...

    if you write ABC in morse it is .- -... -.-.
    not . .. ... like you might expect in binary...

    I thought Morse code was like variable-width Unicode in this
    regard, where the prefix is sufficent to decide whether a
    character is terminated or another dash or dot is pending.
    Now I see I was wrong.

    yeah, there is no prefix in morse... it is too old to have such concepts...

    FWIW: the above line i wrote without any silence spacing is ABCD but it could be decoded as one of several others depending on how one breaks it apart...

    .- -... -.-. -...
    A B C D

    speed is another factor with morse code... if you can easily hear 20WPM but have problems at 30WPM, you might miss some things and get a wrong decode...

    It may be interesring to construct an optimal Mosre-like
    code in which no letter-code is the prefix of another. Then
    it would be a truly binary code, albeit harder to decode for
    a human operator...

    Hi, Alexander! Recently you wrote in a message to All:

    I lived in the USSR, I could receive a telegram that

    I haven't seen a telegram for many years, but IIRC they were typed in capital letters by somebody in the telegraph office & delivered in an envelope. The word "stop" was used to indicate the full stop at the end of a sentence and there was an extra charge for sending more than ten words.


    I'd expect to see something like this:

    BEST WISHES ON YOUR BIRTHDAY STOP SEE YOU SOON STOP

    ARRIVING VIA EDMONTON FRIDAY DECEMBER 23 AT CN STATION STOP

    THE KING IS DEAD STOP LONG LIVE THE QUEEN STOP

    In other countries &/or other languages there may have been some variations. I imagine a lot may have depended on the content as well. When the idea could be reduced to short, simple sentences "stop" usually met most people's needs. :-)
