Morse Code FactsMorse code is used to send telegraphic information through twosignal durations as dots and dashes that correspond to thealphabet, numbers, and punctuation. It transformed how peoplecommunicated with each other across long distances.HISTORY AND DEVELOPMENT Samuel F. B. Morse, along with LeonardGale and Alfred Vail, was able to develop atelegraph with a single circuit. Using thistelegraph, the operator key is pushed down,sending an electrical signal to the receiverthrough a wire.Around 1837, Morse and Vail developed acode that assigned a set of dots and dashesto the alphabet and numbers based on howoften they are used in the English language.Samuel Morse, theinventor of Morse codeKIDSKONNECT.COM
Morse Code Facts Simple codes were assigned to letters that are frequently usedand those that are not used as often had more complex andextended codes. For example, the letter E, which is commonlyused, is represented by while the letter Q is.On May 24, 1844, Samuel Morse sent the first Morse telegraphfrom Washington, D.C., to Baltimore, Maryland.In Samuel Morse's telegraphsystem, a paper tape isindentedwithastyluswhenever an electric current isreceived.Duetoitsmechanical components, thereceiver makes a clickingsound whenever the stylusA telegraph sounder (left) and key (right)moves to mark the paper tape.The operators initially translated the message based on theindentations on the tape but soon they realized they couldtranslate these clicks directly into dots (dits) and dashes (dahs)without the need to look at the paper tape.The earliest version of the code only included numerals thatrepresent words compiled in a codebook. Alfred Vail expandedthis code in 1840 to include letters and special characters. Thiscode became known as the Morse landline code or the AmericanMorse code and was used since 1844.In 1848, Friedrich Clemens Gerke proposed a more refinedversion of the code, which became known as the "Hamburgalphabet." This alphabet was later on adopted by theGerman-Austrian Telegraph Society in 1851. In 1865, theInternational Morse code was standardized in Paris at theInternational Telegraphy Congress in 1865.KIDSKONNECT.COM
Morse Code FactsMODES OF TRANSMISSION Using a phone’s torch lightto send Morse code Morse code was initially transmitted aselectrical pulses on a telegraph wire, but itcan also be sent in many ways. It can becarried as an audio tone, as short andlong radio signals, or as visual code likeflashing light. Some mine rescuers pulledon a rope to send a Morse code: quickpull for dots and long pulls for dashes.Historians have called the Morse code thefirst digital code.Experienced operators are faster in sending and receiving Morsecode messages. Slight variations in the duration of dashes orgaps are introduced by the skill of the operators. This is calledtheir "fist," and the more experienced ones can recognize theindividuals who sent the particular message by the fist alone.RISE AND DECLINE OF THE CODE Journalists and newspaper businesses greatly benefited inelectric telegraphy. Pieces of news can be transmitted in Morsecode between stations almost instantly.During World War II,radiotelegraphy or electrictelegraphy was used forlong-rangeship-to-shipcommunication. Encryptedmessages using Morsecode was favored againstMorse code was used extensively to sendmessages to armed forces during Worldthe unsecured voice radioWar IIKIDSKONNECT.COMsystems on ships.
Morse Code Facts Morse code was also used by long-range patrol planes that weretasked to scout enemy cargo ships, troopships, and warships.The famous S.O.S., though it mayseem to be an abbreviation, is actuallyjust a distinctive Morse code used as adistress signal. This Morse code istransmitted with no spaces betweenthe sequence of dots and dashes.SOS was chosen in the firstBecause it is highly used inInternational RadiotelegraphConvention as the standardemergencies, S.O.S. has been usedmaritime distress signalinformally to indicate a crisis.On January 31, 1997, the French Navy stopped using Morsecode and transmitted the final message "Calling all. This is ourlast cry before our eternal silence."On July 12, 1999, the final commercial Morse code transmitted inthe United States signed off with Samuel Morse's 1844 message.The Morse code S.O.S. was an international standard formaritime distress until 1999 when the Global Maritime DistressSafety System (GMDSS) replaced it. The development of newtechnology for communicationmade the regular widespreaduse of the telegraph fall down.It was soon replaced with moreconvenientwaysofcommunication.
