Low-power nonprofit FM stations are the still, small voices of media. They whisper out from basements and attics, and from miniscule studios and on-the-fly live broadcasts. They have traditionally been rural and often run by churches; many date to the early 2000s, when the first surge of federal licenses were issued. But in the last year, a diverse new wave of stations has arrived in urban America, cranking up in cities from Miami to the Twin Cities in Minnesota, and especially in the Northwest, where six community stations began to broadcast in Seattle.
