A rule of public speaking is to "know your audience", and this is true in politics, advertising and radio broadcasting.
Part 15 radio stations have the easiest opportunity to become familiar with their potential audience, because you can see their houses from your window.
Make a map of your coverage area showing the homes within your radiant circle, collect all the data you can about those houses... addresses, phone numbers, e-mail addresses, names, occupations, tastes and radio inventory.
Once compiled and collated the station operator will have some idea what format might best attract those people.
Otherwise do what I do and broadcast what you like and let them take it or leave it.
I'm my audience so I don't care...
A broadcaster never really knows who is listening or, at times, whether anyone is listening.
We can imagine an audience.
The most interesting woman in town is hearing me and hopes one day to meet someone like me.
The boss at the really large station, who tunes in daily, is wondering why he hasn't made me a job offer.
Upscale listeners consider my station a symbol of their high status.
Careers are being born as schoolers hope someday to have a microphone like mine.
CD sales are on the rise as people collect the music they've heard on my station.
Members at part15(dot)us are modeling their stations after mine.
Am I rich yet?
