WBEZ's experimental station, Vocalo, has been a long time coming to Chicago airwaves, but they cleared a big barrier last week when their proposal to build a 595-foot transmission tower near Chesterton, Indiana was approved, which will allow them to bump up from 7,000 watts to 50,000; a previous proposal to build a smaller tower at a nearby site had been delayed. Meanwhile, you can listen to them online, check out their open blog, tell them your favorite cuss words, or read WBEZ general manager Torey Malatia's manifesto for the station: "It will air a continuous, seamless talk-based stream completely devoted to Northwest Indiana and Chicago metropolitan area culture, issues and selected music. It is not a news station. There are no newscasts."  (h/t Andy)
