Cracking the Code Morse Code as an everyday communication device may have been superseded some time ago, but it leaves a lasting legacy for today’s boaters.

In reality
However, having the idea was one thing, putting it into practice would be more difficult until, with US Government backing, in 1844 Morse as able to construct an experimental network that ran alongside the railroad tracks between Washington and Baltimore, a distance of some 38 miles. The first demonstration transmission was a biblical quotation (“What hath God wrought”), and with the combination of the Morse Code and the line repeater, the telegraph network was launched the following year. In less than five years, some 12,000 miles of wire were erected.

Already, though, the development of ‘wireless’ communication (i.e. radio) was already sweeping away what just a few years earlier had been leading edge technology. By the end of the 19th century, although the wireless transmission of voice was still a technical challenge, Morse code was working well, not just for ground based stations but at sea on ships. By 1905 the outcome of the SinoJapanese war was in part determined by ship borne radio, with the use of a scouting screen of warships able to report back on the location, speed and direction of the enemy fleet. Such was that pace of change that just five years later, messages were being

part from the stunning Barrington Pheloung theme music to the TV Detective series ‘Morse’, which features the letters of the lead character’s name being tapped out repeatedly to underscore the main musical notes, the chirpy dots and dashes of the Morse Code are virtually unknown today. Even the famous ‘SOS’ signal comprising three dots, followed by three dashes, then three more dots, has been replaced by the DSC Distress call, as today the idea of Morse Code fades like fax machines into the category of ‘how we used to do things’. Such is the pace of technological change that the commercial use of Morse Code would last for just over 150 years. However, that period would encompass the whole history of long-distance communications, from the earliest days of electromagnetic telegraphy to the almost infinite capacity of today’s connectivity, either via fibre optics or increasingly courtesy of a satellite link. There would be some amazing innovations surrounding the very first telegraphs, with clever combinations of electrical pointers that together indicated a letter in the alphabet. What was needed, though, was a faster and more robust method of sending the characters more quickly, along fewer wires.
Changing times
Art of inventing
The big surprise is that the innovative mind that would solve this issue would not be one from a classic engineering background, but instead would come from the fine arts. For the first 40 years of his life, Samuel Finley Breese Morse had developed from his early life at home at Charlestown, Massachusetts into a painter of extraordinary talents. At the age of 20 he came to study in the UK, where he would be admitted into the Royal Academy. As his talents and reputation as a painter grew, Morse would travel, firstly home to the US, then back to the UK and Europe. It was on a return voyage home in 1832 that he encountered a fellow traveller, Bostonian Charles Jackson, who was conducting a number of experiments in the field of using electro-magnetism to transmit messages. Morse became involved in the topic and over the next few years he worked to develop a code that could be used for transmitting numbers, but not letters. Each three or four digit number would refer to a word, which would have to be looked up in a dictionary so that the received message could be decoded. Morse also completed further work in conjunction with another American innovator, Alfred Vail, who some believe is the true author of the dot and dash code, although in 1838 Vail wrote to his father that “Morse has invented a new plan of an alphabet and has thrown aside his directories”.

successfully transmitted in Morse from an airship. Wireless telegraphy would become so engrained into the military that it is hard to envisage how a modern, mobile mechanised war such as the 1939-45 conflict could have been fought without the use of Morse’s code. The key thing was that it did not matter which language the original message was in, as for Morse code they are all one and the same, as the dots and dashes just represent the letters of the alphabet.
Going digital
Yet the demands of wartime would also drive the rapid development of more practical radio sets that come peacetime would be small and robust enough for use at sea in the leisure yachting market. All that was left was for the world to go digital and the end would be in sight for Morse’s wonderful code, though amateur radio ‘hams’ would still reach out across the airwaves with their dots and dashes. On 12 July 1999, the final US commercial message transmitted by Morse code was sent, which was then followed by the same “What hath God Wrought” that had introduced the service some 155 years earlier. The ‘dit – di – dah - dit’ sounds may be no more, but we are left with one addition to our everyday vocabulary: back in the days of Morse, the dash was often referred to as an ‘umpty’ from which today we have the word ‘umpteen’. This may be a small reminder, but it is one of a big development that was the start of us All images: Andrew being connected, wherever we are.Wiseman
