What is a good Jazz/Swing Radio Station?

I think it's FM 88.5
I know it's in the 80's

in the Seattle area, it's 88.5 KPLU. half the time it's news (NPR) but it has a lot of good jazz.

Try this: The Jazz http://www.the-jazz.co.uk/

It seems pretty good....

The only one that I have found that I really like is the Yahoo radio station titled as Big Band/Swing.

Since you have a computer I think the best overall Jazz radio is AOL.com or the AIM6 radio.
