Among the most revolutionary devices in terms of telecommunications is, without a doubt, the telegraph. By allowing people in different parts of the planet to communicate in near real time for the first time, it is considered to have been a key to globalization and a precursor to the methods we use today, such as the telephone, mobile phones and the Internet.
However, to get to that point, the telegraph, which first appeared in 1774, had several versions. And they weren’t always so practical. Before Samuel Morse created his famous Morse Code in 1837, the telegraph had 26 wires, one for each letter. It was thanks to this “alphabet” that it could be reduced to a single line, which facilitated the transmission of messages xnxx.
Morse was not a scientist, but rather a painter. However, after belatedly receiving the letter announcing the death of his wife, he decided to create a telegraph that would have a national reach. With the help of Leonard Gale, a professor of science at New York University, they achieved their goal between 1832 and 1837.
Since then, Morse code, based on a system of dots and dashes to represent each letter, has been used in official communications for more than 150 years. Although it is no longer the main means of communication, it is still used in certain areas such as Boy-Scouts, radio amateurs (until 2005 it was mandatory to pass a Morse test to get a license) and instrumental aviation.
Likewise, the International Morse Preservation Society is an organization with thousands of members that is in charge of keeping this means of communication alive. If you’re curious about how to read Morse code, keep reading.
HOW IS THE MORSE CODE USED?
As we mentioned earlier, Morse code is a binary system that uses two symbols to represent each letter: the dot and the dash. For example, E is represented by a point and it is the simplest letter. However, others have up to four symbols like the Y, which is dash, point, dash, dash.
To convey a message in Morse, time is key. The point is transmitted with a minimum pulse. For its part, the line must be three times longer than a point. Likewise, spaces are key to being able to emit a readable message. Between letter and letter a time equivalent to three points must be left, while between word and word it is three lines.
Without a doubt, learning Morse code is not just anything. But there are some tricks that can help make the task easier. One of the most used in the world consists of associating a keyword with each letter or number and this will give us its equivalent in Morse. An example is the word “tree” for A. And it is used like this:
- The initial of the keyword is the corresponding letter.
- The number of vowels that the keyword contains indicates the number of digits in Morse code.
- If the vowel is an O, it is replaced by a dash (—). While if it is any other vowel it is replaced by a point (·).
- When substituting, only dots and dashes obtained up to the full length in Morse code will be taken into account.
- Thus, the word “tree” has two vowels: a and o, which would be a point and a dash respectively. That means that the “a” in Morse code is represented by a dot and a dash.
