Morse code is a special way of coding various language characters - letters, punctuation marks, as well as numbers using sound signals. Two types of signals are used: short indicates a point, long indicates a dash. Initially, the Morse code was used in a telegraph.
Morse code was invented by the American Samuel Morse in 1838. Samuel came up with the idea of creating an information transfer system after the publication of M. Faraday's books, as well as Schilling's experiments. Morse worked on his brainchild for more than three years, until his work was crowned with success. The first signal was sent to him by a wire whose length was 1, 700 feet. The experiments interested Steve Weil, who funded the Morse experiments. It was thanks to him that on May 27, 1844, the first related message was sent, the text of which sounded like this: "Your deeds are wonderful, Lord."
Of course, over time, the system has changed and improved. The final version was proposed in 1939. An interesting fact is that Morse code itself began to be called only with the outbreak of the First World War. It was at that time that its “continental” version became widespread.
Like any sign system, Morse code has both advantages and disadvantages. Among the advantages of this code can be distinguished such as the ability to record and play back signals using the simplest devices, the ability to manually encode, as well as high immunity to interference, provided that the message is received by ear, even in the presence of strong radio interference.
As for the shortcomings, these include low telegraphy speed, the code itself is of little use for direct printing, and besides, the transmission of one such sign requires an average of about 9-10 elementary parcels, which is rather uneconomical.
The most famous signal that Morse code transmits is SOS. This signal can only be given in situations where there is an imminent threat to the life of people or a ship at sea. Despite the fact that many interpret the SOS signal as “Save our souls” (translated as “save our souls”) or, according to some, “Save our ship” (save our ship), this is absolutely not so. This type of signal was chosen only because of its simplicity: three points, then three dashes and again three points, which is quite easy to remember.
How to remember all the characters transmitted using Morse code? Chants are one of the best known and easiest ways to learn Morse code.
The tunes are the rhythmic pronunciation of various sets of dashes and dots. It is worth noting that syllables, which include such vowels as "a", "s" or "o", indicate a dash, and the remaining syllables, as well as the sound "ay" - a dot.
For example, the letter “i”, consisting of two points, is memorized by chanting the word “i-di”, and the letter “k” (-.-) is memorized using the phrase “kaaak-same-taaak”.
Today, there are many different programs with which you can study the Morse code, synthesize messages, encode and decode information using the ABC, as well as practice receiving and sending Morse signals using light.
Despite the fact that in our time there are many new systems and codes for transmitting information, Morse code is still popular among radio amateurs.
