History:
The Q-code was originally instituted at the Radiotelegraph Convention held in London, 1912. The Q-codes then grew over the years and decades.
The following list of current Q-codes is compiled from various sources.
The QAA...QNZ series are reserved for the aeronautical service.
(ICAO Procedures for Air Navigation Services, Abbreviations and Codes (PANS-ABC) [Doc8400])
The QOA...QQZ series are reserved for the maritime services.
(ITU RR1990, Appendix 14)
The QRA...QUZ series are for use by all services.
(ITU RR1990, Appendix 13, 14)
The QZA...QZZ series for other usage.

ICAO PANS-ABC Doc8400 :
The ICAO Q Code
Editor's note: The following codes have been found in an older editions of Doc8400 up to Doc8400-4 (4th edition 1989).
The Q-codes have been deleted and are no longer part of revised editions since Doc8400-5 (5th edition 1999), so it is historical stuff now.
1. The meanings of the Aeronautical Code signals were assigned by ICAO.
Since, in general, only stations of the Aeronautical Service will have available copies of the Aeronautical Code it should not be used in communications with stations of other services unless it is known that the station concerned is familiar with the code.
2. Q signals may be amplified or completed by the addition of appropriate location indicators, approved abbreviations, signals, call signs, figures or numbers.
2.1. The information necessary to complete a signification, as indicated by a blank space, shall be given except when:
(a) The blank spaces are enclosed within parentheses to indicate that their completion is optional.
(b) an alternative meaning shown in parentheses is selected and the blank space in this alternative meaning is completed.
2.2. The information used to complete the blank spaces shall be sent immediately after the Q signal in the sequence shown in the signification.
2.3. Expressions or words in parentheses which do not include blank spaces have the following significance:
(a) when following a blank space, the explanation of the information to be used in filling in the preceding blank.
(b) when following a word or expression, an alternative to the word or expression.
2.4. Q signals shall be read as a question when followed by a note of interrogation signal (IMI). When a signal is used as a question and is followed by additional or complementary information, the note of interrogation signal shall follow this information.
2.5. Q signals that are capable of being given an affirmative or negative sense shall be read in the appropriate sense when immediately followed by the signal YES in the case of the affirmative or the signal NO in the case of the negative.
2.6. Q signals used in the aeronautical service that are capable of being given the sense of an order shall be read in this sense when immediately followed by the signal ORD.
2.7. Q signals with numbered alternative significations shall be followed by the appropriate figure to indicate the exact meaning intended. This figure shall be sent immediately following the Q signal.
2.8. All times shall be given in Greenwich Mean Time (GMT) unless otherwise indicated in the question or reply.
