SOS is a Morse code distress signal ( ), used internationally, originally established for maritime use.In formal notation SOS is written with an overscore line (SOS), to indicate that the Morse code equivalents for the individual letters of "SOS" are transmitted as an unbroken sequence of three dots / three dashes / three dots, with no spaces between the letters.

Morse code. 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 .
To station S2YZ from station S1ABC: Over to you only. S2YZ transmits Morse message: S1ABC DE S2YZ = TNX FB RPRT DR OM JOHN UR 559 = QTH BARCELONA = NM IS ANDY S1ABC DE S2YZ KN. To station S1ABC from station S2YZ. Thanks for the good report. (FB or Fine Business means "good") 'dear old man' John. You are [RST] 559.
SOS is just that—SOS. It was derived from Morse code and recognized as an international standard signaling danger, or the need for aid. Using wireless telegraphy, it would sound like three-dits ...
By 1908, the triple dot-dash-dot code became the official international radio distress signal and remained that way until 1999, when Morse code was declared all but dead.
By 1908, the code we know and love took effect as the official international radio distress signal, and remained that way until 1999, when Morse code was declared all but dead.
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 ...
The procedure signs below are compiled from the official specification for Morse Code, ITU-R M.1677, International Morse Code, [1] while others are defined the International Radio Regulations for Mobile Maritime Service, including ITU-R M.1170, [8] ITU-R M.1172, [4] and the Maritime International Code of Signals, [5] with a few details of their ...
