Q codes were developed by Morse Code operators as a method of communicating quickly and accurately. Rather than send a complete phrase, Q codes were developed to cover most operational situations. Q codes can be used to ask or answer a question, and can be used by operators who speak different languages.

Q codes are approved by the International Telecommunications Union (ITU) for use on worldwide radio networks.

For instance if an operator wants to change to another frequency, he can simply advise the party he is speaking with “QSY 7050” meaning “I will change my operating frequency to 7050Khz”. Similarly he could ask “should I change to 7050Khz” by simply saying “QSY 7050”.

So the next time you hear an operator using a Q code, spare a thought for those old-time morse code operators and the time saved by using Q codes.
