If you are just broadcasting online then you all you need is a server. Depending on your internet upstream speed and how much bandwidth you allocate to each stream you could probably set it up at home and host 5, 10, 20 listeners or more.
If broadcasting on FM then you need a license. I've looked into it and even after you obtain the license it is a huge pain in the ass and pretty expensive. A bare minimum station in a small area will be at least $3,000 a month.
