Editing CQD (section)

==Background==
Landline and submarine telegraphers' [[telegraph]]s had adopted the convention of using the station code "[[CQ (call)|CQ]]" to all stations along a telegraph line. As the first wireless operators were taken from the already trained landline telegraphers, the current practices carried forward and CQ had then been adopted in maritime radiotelegraphy as a "general call" to any ship or land station.<ref>{{cite journal |url=https://babel.hathitrust.org/cgi/pt?id=mdp.39015076479271&view=1up&seq=725 |title=Stranger Than Fiction |author=E.

The Marconi company added a "D" ("distress") to CQ in order to create a distress call. Thus, "CQD" was understood by wireless operators to mean ''All stations: Distress''.{{efn|Contrary to popular belief, CQD does not stand for "Come Quick, Danger", "Come Quickly: Distress", "Come Quick – Drowning!", or "C&nbsp;Q Danger" ("Seek You, Danger"); these are [[backronym]]s.<ref name=Campbell2008/>{{rp|page=218}} }} Although used worldwide by Marconi operators, CQD was never adopted as an international standard, since it can easily be mistaken for a mere general call "CQ" when reception is poor.<ref>{{cite book |url=https://babel.hathitrust.org/cgi/pt?id=uc2.ark:/13960/t12n52m8w&view=1up&seq=372 |title=Steamship Conquest of the World |author= Frederick A.
