NATO Phonetic And Morse Code Alphabet, from the US Navy Signalman 3 & 2 training manual, 1996. This table combines the ICAO international spelling alphabet and the ITU International Morse Code. The Allied military phonetic spelling alphabets prescribed the words that are used to represent each letter of the alphabet, when spelling other words out loud, letter-by-letter, and how the spelling ...
Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [ 3 ][ 4 ] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy.
Code talker. Checked. Choctaw soldiers in training in World War I for coded radio and telephone transmissions. A code talker was a person employed by the military during wartime to use a little-known language as a means of secret communication. The term is most often used for United States service members during the World Wars who used their ...
Morse code mnemonics are systems to represent the sound of Morse characters in a way intended to be easy to remember. Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds. Amateur radio clubs can provide resources to learn Morse code.
The Allied Translator and Interpreter Section (ATIS), also known as the Allied Translator and Interpreter Service or Allied Translator and Intelligence Service, was a joint Australian / American World War II intelligence agency which served as a centralized allied intelligence unit for the translation of intercepted Japanese communications, interrogations and negotiations in the Pacific ...
World War II cryptography. Cryptography was used extensively during World War II because of the importance of radio communication and the ease of radio interception. The nations involved fielded a plethora of code and cipher systems, many of the latter using rotor machines. As a result, the theoretical and practical aspects of cryptanalysis, or ...
Morse code abbreviations are used to speed up Morse communications by foreshortening textual words and phrases. Morse abbreviations are short forms, representing normal textual words and phrases formed from some (fewer) characters taken from the word or phrase being abbreviated.
M-209. The M-209. In cryptography, the M-209, designated CSP-1500 by the United States Navy (C-38 by the manufacturer) is a portable, mechanical cipher machine used by the US military primarily in World War II, though it remained in active use through the Korean War. The M-209 was designed by Swedish cryptographer Boris Hagelin in response to a ...
