I used to be an OPB devotee. I still listen to KMHD and KBOO a decent amount. But more and more these days, the local radio I most want to listen to is XRAY.FM.
In the two years since its founding, the station's massively expanded its broadcast territory, and brought on a slate of progressive programming and local DJs that play a delightful array of cuts at all hours of the day. True, the Mercury has a weekly slot on XRAY—for 15 minutes or so at 8:30 am on Thursdays—and we've cosponsored events with them, but my affinity for the station extends well beyond any of that.
The station's on the last day of a fundraising drive, today. You should donate or become a member.
