A specific frequency on the FM radio dial is often associated with a broadcasting station. Contacting such a station can sometimes be achieved through a telephone number connected to that frequency. As an example, a listener seeking to participate in a radio contest may need to dial the station directly.
The capacity to directly engage with a broadcast entity provides listeners with immediate access to on-air personalities and station services. Historically, this was a primary method for audience interaction and remains relevant for real-time communication, contests, and emergency broadcasts. The integration of telephone communication with radio frequency broadens the possibilities for user involvement and feedback.
