Low-Power Radio's Voice Rises

Low-power noncommercial radio stations, which emerged about 10 years ago in a brief window of eased federal regulation intended to foster competition with the big corporate radio chains, might be soon about to roar, some communications experts say — or at least squeak loudly enough to be heard. A bill now before Congress, and considered by some low-power radio advocates to have a good chance of passage this year, would potentially double the number of licensed, low-power stations from about 800 now to perhaps 1,600 or more. At the same time, technology is shifting the boundaries and definitions of what it means to be local, and even what it means to be radio. Internet streaming and digital wireless reception are combining in ways that could allow almost any station, even one broadcast from a front porch, to be heard anywhere in the world from the next generation of hand-held devices and smartphones.
