Morse - a special way of encoding different language characters - the letters, punctuation, and numbers using audio signals.Use two types of signals: a short denotes the point, long - dash.The original Morse code used in telegraphy.
Morse code was invented by Samuel Morse American in 1838.The idea to create a system for transmitting information, visit after Samuel M. Faraday's books, as well as experiments Schilling.Morse worked on his brainchild for over three years, until his efforts were not successful.The first signal was sent to them on the wire, the length of which is 1,700 feet.Experiments are interested in Steve Weil, who financed the experiments of Morse.It is thanks to him 27 May 1844 sent the first bound message, the text of which was: "marvelous are thy works, O Lord."
Of course, over time the system changed and improved.The final version was proposed in 1939.An interesting fact is that Morse code itself began to call only the beginning of the First World War.It was at the time widely spread its "continental" option.
Like any system of signs, Morse code has both advantages and disadvantages.Among the advantages of this code can be identified such as the ability to record and play back signals by using simple devices, the possibility of manual coding, as well as high immunity to interference, provided receipt of the message at the hearing, even with the presence of strong interference.
the negative side, these include low-speed wiring, the code itself is unsuitable for receiving direct-printing, and also to the transfer of one such sign takes an average of about 9-10 chips, which is quite uneconomical.
most famous signal that transmits Morse code - SOS.This signal is allowed to submit only in situations where there is an imminent threat to human life or the vessel at sea.Despite the fact that many of the SOS signal is interpreted as «Save our souls» (translated as "Save Our Souls"), or, according to some, «Save our ship» (save our ship), it is absolutely not true.This type has been selected only because of its simplicity: three dots, three dashes, and then again three points, which is quite easy to remember.
How to remember all the signs transmitted using Morse code?Tunes - one of the most well-known and easy ways to learn Morse code.
tunes are rhythmic pronunciation of the different sets of dashes and dots.It is worth noting that the syllables composed of vowels such as "a", "s" or "o" denote the dash, and the rest of the syllables and sound "ah" - point.
For example, the letter "i", which consists of two points, using the tunes memorized the words "and di" and the letter "k" (-.-) - using the phrase "same-kaaak soooo."
Today, there are many different programs that can be used to study Morse code, synthesized messages to encode and decode information using the alphabet, as well as to train and receive Morse signals are fed with light.
Despite the fact that nowadays there are a lot of new systems and codes of information transmission, Morse code was still popular among radio amateurs.
