Every want-to-be microbroadcaster is going to run into the same inevitable needs, questions and shopping list for pieces.
Arguably, aside from the content itself, the most important needs are a transmitter, an antenna and place to effectively mount the equipment.
I settled on the Talking House V transmitter solely because it is widely available and affordable. At $99 + shipping for a new unit or half that if you watch for used units (Ebay, Craigslist, etc.), it makes the daydream of broadcasting a cheap thing most of us can actually do.
