'''CQD''' (transmitted in [[Morse code]] as {{morse|noindent=yes|dash|dot|dash|dot}}{{morse|dash|dash|dot|dash}}{{morse|dash|dot|dot}}) is one of the first [[distress signal]]s adopted for [[radio]] use. On 7&nbsp;January 1904 the [[Marconi Company|Marconi International Marine Communication Company]] issued "Circular&nbsp;57", which specified that, for the company's installations, beginning 1&nbsp;February 1904 "the call to be given by ships in distress or in any way requiring assistance shall be 'C&nbsp;Q&nbsp;D'&nbsp;".<ref name="CQD">{{cite book |url=https://babel.hathitrust.org/cgi/pt?id=mdp.39015064554713&view=1up&seq=368 |chapter=Distress Signalling |first=G.E. |last=Turnbull |title=The Year-book of Wireless Telegraphy and Telephony |year=1913 |pages=318–322 |access-date=21 August 2019 |archive-date=5 January 2021 |archive-url=https://web.archive.org/web/20210105080658/https://babel.hathitrust.org/cgi/pt?id=mdp.39015064554713&view=1up&seq=368 |url-status=live }}</ref>
