With Hawaiian, reggae, blues, world music, women's voices, KUNV is much more than jazz. The weekend programming is where it's at. Start listening around 10 AM on Saturdays and keep listening until late Sunday night. You will hear a new program about every 2-3 hours. It's really hard to pick favorites, but mine are Grass Shack, CQDX, and Latin Nights.
KUNV's local hosts are knowledgeable volunteers who care about their genres. They actually talk about the songs and artists they play.
I've listened every weekend for the past 6 years. During the weekdays they play pretty much jazz only. 91.5 is UNLV's radio station and it's available online at http://kunv.unlv.edu/streaming.htm
