Morse Code And The Phonetic Alphabet

Morse Code and the Phonetic Alphabet

Both Morse Code and the Phonetic Alphabet have been used by the military world over for almost a century now, and for good reason! Along with the many other things you as a prepper should learn and memorize, memorizing Morse Code and the Phonetic Alphabet should be on that list. Although Morse Code is no longer used in it’s traditional form, it can still be used as an unconventional method to communicate with others long or short distance using radio, lights, sound, and a variety of other methods. As for the Phonetic Alphabet, it’s primarily only used when communicating over radio/digital devices to prevent confusion between similar sounding letters. The Phonetic Alphabet is especially useful when communicating over choppy signals or when in loud environments. Several hours of studying is all it will take to memorize these codes, and it’s very likely you’ll one day need this information.

Now You Can Write Morse Code

Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals as standardized sequences of short and long signals called “dots” and “dashes”, or “dits” and “dahs”. Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.

Each character (letter or numeral) is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots. The dot duration is the basic unit of time measurement in code transmission. To increase the speed of the communication, the code was designed so that the length of each character in Morse varies approximately inversely to its frequency of occurrence in English. Thus the most common letter in English, the letter “E”, has the shortest code, a single dot.

Morse code is most popular among amateur radio operators, although knowledge of and proficiency with it is no longer required for licensing in most countries. Pilots and air traffic controllers usually need only a cursory understanding. Aeronautical navigational aids, such as VORs and NDBs, constantly identify in Morse code. Compared to voice, Morse code is less sensitive to poor signal conditions, yet still comprehensible to humans without a decoding device. Morse is therefore a useful alternative to synthesized speech for sending automated data to skilled listeners on voice channels. Many amateur radio repeaters, for example, identify with Morse, even though they are used for voice communications.

SOS, the standard emergency signal, is a Morse code prosign.

In an emergency, Morse code can be sent by improvised methods that can be easily “keyed” on and off, making it one of the simplest and most versatile methods of telecommunication. The most common distress signal is SOS or three dots, three dashes and three dots, internationally recognized by treaty.

Jeremiah Denton Jr. Blinking Morse Code

Jeremiah Denton Jr., a Navy Captain and also a former US Senator, spent almost 8 years as a prisoner of war in North Vietnam. Denton is best known for the 1966 televised press conference that he was forced into as an American POW by his North Vietnamese captors. He used the opportunity to communicate successfully and to confirm for the first time to the U.S. Military that American POWs were being tortured in North Vietnam. He repeatedly blinked his eyes in Morse Code during the interview, spelling out the word, “T-O-R-T-U-R-E”

What an amazing hero!
