Besides the station’s program format, other factors that influence the announcer’s job include how large the station is and the number of technical and support personnel on staff. At a medium to large size station, the radio announcer can usually rely on a broadcasting technician to operate the electronic equipment and an engineer to cue the announcer’s broadcast actions and play pre-recorded commercials, messages and music. At small stations, the radio announcer is frequently required to perform all these jobs herself.
