The Q Code
Newcomers are often puzzled by the codes and abbreviations used by radio amateurs. These codes make international communication possible with operators with little knowledge of English and they save time conveying information.
A full listing of the Q Code can be found in publications of the International Telecommunication Union.
Listed below are some Q-codes used by radio amateurs.
The Q Code is used in two ways - with or without a question mark. Sometimes a figure, a callsign or a frequency, accompanies a Q-code. For example:
(the question mark) means "have you any messages for me?".
means "I have three messages for you".
