Radio stations for Jazz....


I've just found KNTU for Jazz. I like it.
ptss
I listen to http://www.jazz24.org and http://thejazzgroove.com quite a bit. The Jazz Groove is lighter jazz (not smooth jazz) and is often the way I start my mornings.
You can sign up for a free service on www.tunein.com and stream FM stations from all over the U.S., save off your favorites.  Great sound quality and you can't beat the price.
A few I listen to and like. All available from tunein
