You would never be able to monetize whatever small group of fringe listeners you attracted. Sorry to sound harsh, but it's a business and that summary as the start of a business plan will not result in a viable operation.Right....my station would be geared to people who enjoy music and would love to relive the great times, with great classics. They don't need to listen 24/7. An hour or two every now and then would suffice to my target, people who lived the day. My target audience is not yours. My target would enjoy and rarely, if ever complain. It's a concept that needs to return to the airwaves and if I had the money, I'd do it in a heartbeat, even as a small 50 watter.
There's a reason things work the way they do. People whose ability to "put food on the table" for their families and invest their careers in understanding those reasons know more than hobbyists with an axe that always seems to need grinding.
