How would I go about getting this job?

I’ve always wanted to be a radio DJ. Not like a DJ at parties but an actual radio DJ. I love music and for some reason that job always seemed like the perfect one. It always seemed fun and what not. But I’m not sure how to go about finding information about the requirements and about what kind of education one would need. Its always been an idea I’ve toyed with and I’m wondering if I could make it a reality.
