Morse Code Reading Passage

Paragraph A: 

A new satellite-based system is being implemented to replace Morse code for sending distress calls at sea. Since 1992, when the Global Maritime Distress and Safety System was established, nations have been gradually retiring their Morse equipment with similarly solemn (though less lyrical) farewells as the world's shipping community transitions to the new satellite-based system. Many people consider February 1st the end of an era, as that is when the transition to GMDSS must be completed. Even while some people (amateur radio operators, spies, and some military personnel) will continue to utilise dots and dashes after the transfer to GMDSS, this will be the end of the final major international usage of Morse.

Paragraph B: 

However, the code has a solid background behind it. According to legend, Samuel Morse came up with the idea for Morse code while he was on a ship crossing the Atlantic, which is fitting for a technology so closely connected with radio operators on doomed vessels. Morse, who was a painter and occasional inventor at the time, became fascinated with the concept of creating the electric telegraph after hearing about recent developments in electrical theory from another passenger on the ship. For the better part of a century, other innovators have been striving to achieve the same goal. Morse's success and legacy as the telegraph's "father" might be attributed in part to his dogged determination; it took, for example, 12 years for him to gain funding from Congress to build his first telegraph line.

Paragraph C: 

Morse's design for the electric telegraph was much more straightforward than its competitors; all it took to transmit a message was a "key" (basically a spring-loaded switch), a "sounder" (an audible signal), and a wire. Morse's technology was straightforward, but it required operators to master a unique system of dots and dashes. Morse didn't set out to depict letters using combinations of dots and dashes. While crossing the Atlantic, he sketched up his first code, which used dots and dashes to represent the numbers 0 through 9. Morse proposed that messages be made up of sequences of numbers that would be mapped to words and phrases in a unique numerical lexicon. Later, however, Morse gave up on that plan in favour of developing the Morse alphabet with his friend and colleague Alfred Vail. This system allowed for the individual letters of words to be represented by dots and dashes. Morse's telegraph appeared insurmountably difficult at first because of the necessity to master this complicated-looking code, especially in light of previous, more user-friendly designs. With Cooke and Wheatstone's telegraph, for instance, five needles were employed to select individual letters from a diamond-shaped grid. This meant that anyone could use the telegraph, but it also necessitated the use of five lines to connect each telegraph station. Only one telegraph was required when using Morse's telegraph.

Paragraph D: 

As the use of electric telegraphy spread rapidly in the early 1850s, the Morse telegraph soon became the standard. In 1851, it was officially recognised as the European standard, paving the way for seamless cross-border communication via telegraph. (Great Britain opted not to update their language to account for regional variations and foreign influences.) By this point, Morse code was being used; however, it still relied on needle telegraphs for a few characters, which led to the ongoing division between American and International Morse.

Paragraph E: 

When transmitting data via international underwater cables, dots and dashes were represented by the leftward and rightward movement of a light beam reflected by a tiny spinning mirror. At the same time, a new telegraphic society was developing, complete with its own slang and a social order based on the operators' Morse code speed. In large cities, the highest-paying employment goes to first-class operators who can send and receive at speeds of up to 45 words per minute and hence, handle press traffic. Slow, incompetent rural operators, many of whom only operated the wires on the side, were at the bottom of the totem pole. However, as their proficiency in Morse code increased, rural operators discovered that their newfound expertise was a ticket to higher compensation in urban settings. As a result, telegraphers quickly became a significant part of the newly formed middle class. Work in telegraphy was likewise seen as acceptable for women. As early as 1870, women made up a third of the workforce at the Western Union branch in New York City.

Paragraph F: 

Morse personally bid farewell to the international network of telegraphists he had helped create in a dramatic ceremony in 1871. More than 650,000 miles of telegraph lines and 30,000 miles of underwater cables were pulsating with Morse code, and 20,000 towns and villages were connected to the worldwide network by the time of his death in 1872. The telegraph was once referred regarded as the "instantaneous highway of the idea," much like the Internet is today.

Paragraph G: 

However, the telegraph's time as a cutting-edge technology was coming to an end by the 1890s, thanks to the development of the telephone and the advent of automatic telegraphs, forerunners of the teleprinter, which did not necessitate any specialised training to use. But another innovation, wireless, was going to offer Morse code a second chance. Radiotelegraphy's potential maritime applications became immediately obvious after its creation by Guglielmo Marconi in 1896. Previously, ships were unable to talk to each other or the shore when the weather was bad, or they were too far away to see each other. Marconi used Morse code to communicate with an Italian cruiser located 19 kilometres (12 miles) away in 1897. In 1899, a lightship in the Dover Straits reported the grounding of the steamship Elbe, marking the first maritime rescue after a distress call sent via the radiotelegraph.
