Q code in english

Full international Q-code

This is the complete Q-code as it was defined for maritime radio communication. Since CW communication has been abandoned for this purpose, this code is probably no longer in use.

Here only the "question" part is shown, but every code can either be a question or an answer.

See also the informal amateur radio Q-code.
