In the blizzard of activity Congress undertook at the end of last year, you might have missed one piece of legislation: The Local Community Radio Act was passed in December and signed by President Obama earlier this month. The act frees up the FM dial to make way for more small or low-power signals. One of those stations is serving Chicago listeners right now.

The Chicago Independent Radio Project, or CHIRP, has been broadcasting online for a little over a year. The new legislation will eventually make getting a broadcast license easier but CHIRP isn’t quite there yet. To find out more Eight Forty-Eight spoke to Shawn Campbell, president and founder of CHIRP. Campbell is also a former producer on Eight Forty-Eight.

CHIRP will hold a benefit concert Thursday night at the Hideout.
