Let's say you wanted to broadcast to a city that has a population of 50,000 people.
How many towers, transmitters, offices would you need?
How much would the infrastructure cost to put up?
Is there any government regulation at all?
How would you staff the talk show hosts, the support staff, and how much would it cost?
Could you solicit advertisers for the "station?"
Any problem with the broadcast frequency encroaching on a "normal" station and them taking action?
