As I have said before, radio is not the hot media it is in North America. CBC in Canada is excellent and listed to by a large percentage of the population. In isolated rural areas of the country it is highly valued. North Americans still mostly drive cars to work and they listen to the radio while driving. Not so much on the train. The point of this being that there is an excellent 'How to' from NPR and This American Life in America:Radio: An Illustrated Guide store.thisamericanlife.org :it's a step-by-step primer on how to make a radio story. The book includes detail on where we find our stories, how to structure a story, how to do an interview, how to hold the microphone, how to edit sound, how to write a script...really everything you'd need to get started And as a PDF to download it costs $2.00 a bargain.
