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 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.
