Call Signs
special words, signs, or combinations of letters or numbers assigned to officials, command and control agencies, communication centers and stations, and other bodies so that they can be quickly identified in conversations through signal means and their actual designations kept secret. Conventional sound signals or melodies may also be used as call signs for radio transmitters. Call signs are assigned for the duration of a mission or for a definite period of time, after which they are changed. Want to thank TFD for its existence?
