An amateur radio contact, more commonly referred to as simply a "contact", is an exchange of information between two amateur radio stations. The exchange usually consists of an initial call, a response by another amateur radio operator at an amateur radio station, and possibly a signal report. A contact is often referred to by the Q code QSO. It is often limited to just a minimal exchange of such station IDs. Stations who have made a contact are said to have worked each other. An operator may also say that he has worked a certain country. Amateurs use the slang expression ragchew or ragchewing to refer to an extended, informal conversation, a variation of the common idioms "chewing the fat" and "chewing the rag".[1][2] Sometimes, a contact in person, between two ham radio operators, is humorously referred to as an "eyeball QSO".

An All-Time New One (ATNO) is an operator's contact with an amateur station that he/she has never worked before on any band or mode.
