Subj : Ham Radio History (C) To : ALL USERS From : DARYL STOUT Date : Thu Feb 04 2016 12:03 am CQ The telegraph call CQ was born on the English Telegraph nearly a century ago as a signal meaning "All stations. A notification to all postal telegraph offices to receive the message." Its meaning was close to the present meanings of QNC and QST. Like many other telegraph terms which originated on the landlines, CQ was brought over into radio and used as a general call to all ships by the Marconi Company. Other companies used KA until the London Convention of 1912, which adopted CQ as the international general call or "attention" signal. CQ still means, literally, "attention" but in amateur radio its meaning is perhaps more accurately described by Thomas Raddell who compared it to yelling "Hey, Mac!" down a drain pipe. But why the letters CQ? It's apparently from the French word for safety... or, as intended here, pay attention. --- BgNet 1.0a12 - The Thunderbolt BBS wx1der.dyndns.org Little Rock, AR .
