Meaning of CQD

[WayneDraper]

I have read many books and read about the meanings of SOS.  I believe there are two but could be wrong.  Then I came across CQD and I think

the first part is Come Quick but what does D stand for

Land telegraphs had traditionally used "CQ" to identify messages of interest to all stations along a telegraph line, and CQ had also been adopted as a "general call" for maritime radio use. However, in landline usage there was no general emergency signal, so the Marconi company added a "D" to CQ in order to create its distress call. Thus, "CQD" is understood by wireless operators to mean, "All stations: distress." Contrary to popular belief, CQD does not stand for "Come Quick, Danger", "Come Quickly Distress", or "Come Quick - Drowning!"; these are backronyms.
