Introduction

The Q code is a list of signals that summarize a question or a detailed answer. The code, as decided by the International Telecommunication Union, is used all over the world in terrestrial, maritime and aeronautical telecommunications. Born for radiotelegraphy, it is also used in telephony for its conciseness and for standardizing communications. The use of these international signals is mandatory in all types of communication, military and civil.

Each Q signal consists of three letters, of which the initial is the letter Q. Some groups of codes do not exist; of the others I tried to draw up the most complete list possible, including the codes that are now obsolete or out of order.

The meanings assigned to the abbreviations of the Q code can be extended or supplemented with the addition of other groups, call names, names of places, digits, numbers, etc.

Data in square brackets [] are optional and must be transmitted in the same order in which they appear in the text. Three dots ... indicate a part that must be completed. The italic character indicates the type of information to be given name or quantity.

The abbreviations of the Q code represent a question when they are followed by the question mark. If the abbreviation has additional information, the question mark must follow the latter.

The abbreviations are contained in Appendix 9 of the Radio Regulations Annex to the International Telecommunications Convention (Atlantic City) 1947 (codes from QRA to included QUZ) and in the ICAO publications Dec 6100-COM / 504/1 (codes from QAA to included QNZ).
