Signal that replaced “CQD” :


The combination of three dots – three dashes – three dots, is a Morse signal first introduced by the German government as a standard distress call in 1905. The sequence is remembered as the letters SOS (three dots – pause – three dashes – pause – three dots), although in the emergency signal there is no pause between the dots and dashes, so SOS is in effect only a mnemonic. Similarly, the phrases “Save Our Souls” and “Save Our Ship” are also mnemonics, introduced after the “SOS” signal was adopted.

In the days of land telegraph, the letters “CQ” were used to alert operators to important messages. These letters were used as when pronounced in French they made the abbreviation “sécu”, short for “sécurité”. The Marconi company added to the letter D for “distress” to the “CQ” signal when they introduced their maritime radio distress signal “CQD” in 1904, which was transmitted in Morse code. The CQD signal never gained international recognition, and it was replaced by “three dots/three dashes/three dots” two years later in 1906 (having been introduced in Germany in 1905). This latter signal became known as “SOS”.
