Title: Designing An FM Broadcasting Radio Station
Objectives:
• Be able to appropriately design a radio station for FM broadcasting.
• To be able to specify the desired design equipment .
• Be able to effectively reach the required target coverage area through appropriate
design and proper project implementation.
Background:
Radio is a form of sound communication that uses radio waves to transmit music, news,
and other programming from a single broadcast station to a large number of people who
have radio receivers. Broadcast radio has astonished and pleased the public since its
inception in the early twentieth century by offering news and entertainment with a speed
and immediacy never previously imagined. Between 1920 and 1945, radio became the
first electronic mass medium, monopolizing "the airwaves" and defining an entire age of
mass culture alongside newspapers, magazines, and motion pictures.
It is a highly personal medium, based on the human voice, inviting the listener's
imagination to fill in mental imagery around the broadcast sounds. Radio can calm
listeners with pleasant talk or background music more easily and widely than any other
medium, or it may jolt them back into reality with polemics and breaking news. To engage
and fascinate listeners, radio can use an infinite number of sound and music effects.
Commercial broadcasters and government agencies have made deliberate use of this
medium's unique characteristics to develop programs that grab and hold listeners'
attention since its inception.
Radio is very crucial in our life. When other forms of communication fail in an emergency,
it remains accessible.
According to a Kantar Media poll conducted in 2018, 62 percent of Filipino respondents
said they have accessed media via radio or audio in the previous 12 months. And FM is
one of the most effective radio broadcasting transmission methods in the Philippines.
