Radio operators are individuals who use radio equipment to communicate with other people. The two most common types of radio operators are HAM and CBER. HAM stands for 'amateur radio operator' and is a person who uses radio equipment for non-commercial purposes, such as hobby or recreational activities. CBER stands for 'commercial broadcast engineer and radio operator' and is a person who operates radio equipment for commercial purposes, such as broadcasting music or news. Both HAM and CBER radio operators must be licensed by the Federal Communications Commission (FCC) in order to legally operate radio equipment.
