Titanic NOT the first user
By Brian J. Ticehurst

OVER the years many myths and fallacies have grown up around the Titanic. Not least the myth that the Titanic was the first vessel to use the International Distress Call 'SOS'.
This is not so - the facts are these:-
The first Radio Distress Signal was transmitted from the East Goodwin Lightship on 17 March 1899 when the merchant vessel Elbe ran aground on the Goodwin Sands. The message was received by the radio operator on duty at the South Foreland Lighthouse, who was able to summon the aid of the Ramsgate lifeboat.
The Goodwin Sands again featured in another 'first' when on 30 April 1899, the East Goodwin Sands Lightship sent a distress message on her own account when she was rammed by the SS R. F. Matthews. This was prior to the introduction of the 'SOS' and the recognised call sign for ships in distress then was 'CQD'. This signal had been devised by the Marconi Company, it was intended to mean 'All Stations - Urgent', but was popularly misinterpreted as 'Come Quick - Danger' or 'Come Quickly Down'.
The 'SOS' signal was established as an International Distress Signal by an agreement made between the British Marconi Society and the German Telefunk organisation at the Berlin Radio Conference, 3 October 1906. The signal was
formally introduced on 1 July 1908. The first time the 'SOS' signal was used in an emergency was on 10 June 1909, when the Cunard liner SS Slavonia was wrecked off the Azores. Two steamers received her signals and went to the rescue.
This was nearly three years before the Titanic made her famous signal!
Fact from: The Shell Book of Firsts. By Patrick Robertson. Elbury Press & Michael Joseph Ltd. London.
 
Did the Titanic actually send an SOS or did the stick to CQD?
The Titanic send an SOS and CQD during the sinking, she started with an CQD in her first distress call at 12:27/00:27 and kept it as the main distress signal up until a half hour later, at 12:57/00:57 she send out the SOS Signal. Despite the use of the SOS from a transcript from the messages send out they still used CQD a lot more than SOS.
 
FYI, I believe the second SOS was sent by, the steamship Arapahoe in late summer 1909, after shedding a propellor shaft. She ran a route between New York and and Florida (Jacksonville)
