What Are Q Codes?

Q Codes are a collection of 3 character codes each one having a particular definition. Q Codes are much more commonly used on SSB Radio than on regular AM/FM CB Radio and over most other bands.

Q Codes are commonly used in voice modes but can just as easily be deciphered as Morse code, deriving from the history of navel and other and marine long range radio communications.
Standardised around 1909 it was developed into forty-five Q codes which were published in 1912.

The main appeal of Q Codes is the fact that it could be globally made use of. Anyone can recognise the communication transmitted regardless of what the nationality of the operator or the receiver.

Since initially entering onto SSB Radio for the very first time last year I have become intrigued by the use of Q Codes. Certain codes are used more than others but they typically form part of making a contact in the first place.
