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", initially developed for commercial radio telegraph communication, and later adopted by other radio services, especially amateur radio. Although Q codes were created when radio used Morse code exclusively, they continued to be employed after the introduction of voice transmissions. To avoid confusion, transmitter call signs are restricted; while an embedded three-letter Q sequence may occur (for instance when requested by an amateur radio station dedicated to low-power operation), no country is ever issued an ITU prefix starting with "Q". The codes in the range QAA–QNZ are reserved for aeronautical use; QOA–QQZ for maritime use and QRA–QUZ for all services.

Senang cerita, Q codes ini memendekkan ayat-ayat menjadi kod yang senang difahami. Kalau masuk Continuous Wave [CW] senang nak tulis dan faham apa yang ingin disampaikan. Berguna juga ketika kecemasan dimana setiap maklumat kena pantas dan cepat.
