How to Activate the SOS Feature on iPhone? In 1844, Morse sent the first message “What has God wrought” on this line using this code.īecause of its simplicity the Morse Code continues to be used even as mobile wireless telephones are replacing telegraph transmission. In 1843, the United States Congress approved the first telegraph line from Baltimore in Maryland to Washington DC. The code can be used to read these dots and dashes and translate the message. The electric signals move a metal point to print these dots and dashes on a paper tape.
The dots and dashes travel across the wire and are picked up by a receiving set. These codes were easier to send over the telegraphic line. In 1838, Morse also developed a code that consisted of dots and dashes representing alphabets and numbers. Morse developed the first successful telegraph instrument in 1837.Ĭalled a transmitter, the telegraph instrument converts a message into electrical signals. In 1787, M Lammond, a Frenchman invented the first telegraph line that could send messages over a distance by means of electricity. One can tap it on the telegraph or signal with a torch or even with a flag.īefore the invention of the code, long distance communication consisted of lamp signals from hilltops, smoke signals and shouted messages. The code consists of three dots, three dashes and three dots. SOS is the easiest code to transmit and recognise. The Morse code, as it came to be called, is used to send messages through a telegraph line or the wireless. It is a coded signal for help that continues to be used by ships, planes and stranded people around the world even 162 years after it was invented by the American Samuel Morse, who invented the first successful telegraph instrument in 1837. There are many explanations for what the words stand for: Save Our Souls Save Our Ship Send Our Succour… The meaning of all three is the same – it is a plea for help by someone in distress. Luckily their radio operators knew the Morse code and were able to communicate by knocking on the sides of the ship.
Recently, sailors on the nuclear submarine that sank in the Baltic Sea were isolated from rescue workers as their radio set got damaged.
