Two resources for getting on an audio station or generating any other kind of PR:
1. Joan Stewart -
http://www.publicityhound.com/
2. Book - Guerilla Publicity -
http://www.amazon.com/Guerrilla-Publ.../dp/1580626823
Both will show you how to create a quick media kit. With your Q&A, biosheet and a few samples.
Both give you some ideas on how to approach the media people.
Then there is Paul Hartunian's PRKit too - which I recommend - but its more expensive. -
