This term is part of the Q-code, which is a standardized collection of three-letter codes used to convey specific meanings in radio communication. In this context, a QSO typically involves two ham radio operators exchanging information, such as their call signs, signal reports, and other details relating to their locations and equipment. This interaction can occur in various forms, including voice, Morse code, or digital modes.
