Q Codes
The "Q" code is a standardized collection of three-letter message encodings, also known as a brevity code, all of which start with the letter "Q". Q codes are commonly used in voice communications as shorthand nouns, verbs, and adjectives making up phrases. Q codes can be used to confer information, or when followed by a "?" used to ask a question.
Initially developed for commercial radio-telegraph communication, these codes were later adopted by other radio services, such as marine, aviation, and amateur radio. The codes are broken down into 3 catagories for use in different radio services:
