What is CQ?

CQ code is generally used by radio operators especially those contacting in MORSE CODE for making a normal call, you can say it a “CQ call”. The transmission of CQ letters is actually a request for any radio operator or voice operator to respond the frequency. It is still far used in amateur radio.

History & Usage of CQ

The CQ call was basically used by the UK and French landline telegraph operators, and still, they are using. It is an authoritative language for foreign postal services. And the word which they were using was sécurité. “When a marine radio transmission begins with the phrase “Sécurité, sécurité, sécurité it means that what follows is important safety information.” It is still used in the sense of foreign telecommunications.

The CQ word was derived from the French word and it also sounds like French “c’est qui?”  Which means who is there? In America or in other countries where English is common, the motive of abreaction was changed so rapidly to the phrase “seek you” or later, when used in CQD (Calling all distress).

The first code used as a distress signal was the “CQD” which was the alternative of CQ call. It was approved in 1904 and was suggested by Marconi Company. But was recouped b/w 1906 & 1908 by SOS code.

From history

When the Titanic sank in 1912, however, it initially transmitted the distress call CQD DE MGY, MGY being the ship’s call sign. (The Titanic’s radio operator alternated between SOS and CQD afterward.

When we use amateur radio, at that time, the CQ call can be certified by appending more letters. Like in CQ DX which means “calling all stations located in a different continent to the caller”. Or you the ITU call sign prefix which is for specific homey. E.g. “CQ VK for “calling Australia” The begetter of a call can be analyzed by conjoining the alphabets DE (French for “from”, also means “this is…”) and the call sign of the transmitting station.
