Ama­teur radio (also called ham radio) is the use of des­ig­nat­ed radio fre­quen­cy spec­trum for pur­pos­es of pri­vate recre­ation, non-com­mer­cial exchange of mes­sages, wire­less exper­i­men­ta­tion, self-train­ing, and emer­gency com­mu­ni­ca­tion. The term “ama­teur” is used to spec­i­fy per­sons inter­est­ed in radio tech­nique sole­ly with a per­son­al aim and with­out direct pecu­niary inter­est, and to dif­fer­en­ti­ate it from com­mer­cial broad­cast­ing, pub­lic safe­ty (such as police and fire), or pro­fes­sion­al two-way radio ser­vices (such as mar­itime, avi­a­tion, taxis, etc.).
