Radio Re-Volt: Broadcasting For The Common Man
An anonymous reader writes "Well, almost for the common man. This Wired article describes a project of the Walker Art Museum in Minneapolis to teach people about the power of radio through the use of cheap low-power FM transmitters. Although each transmitter is limited to a range of about a block, they're cheap enough that I could see them being spread out across a city to cover it with a signal. It'd be interesting to do something like that and feed these inexpensive networks via a netcast. You could use something like this to air programming that commercial stations won't broadcast because it's not commercially viable or because it doesn't fit in with the interests of big media. You can read the above article or go directly to the Radio Re-Volt Web site."
That culture and new ideas can come from "that place you fly over on a SFO-JFK flight."

And I think you do need a license to operate a CB radio.
No you don't.
Citizens Band (CB) Radio Service is a private two-way voice communication service for use in personal and business activities of the general public. Its communications range is from one to five miles.
Licensing
License documents are neither needed nor issued and there are no age or citizenship requirements. As long as you use only an unmodified FCC certificated CB unit, you are provided authority to operate a CB unit in places where the FCC regulates radio communications.
