Funny, I live in Morgantown and spend alot of time in Martinsburg.
I used to be able to access WAJR on my on my old 6700. I think I did it through IE, but I'll have to try to remember the site. Maybe LisaT96 has already found you a solution though.
Edit: I think it was WVAQ and not WAJR. They also cover the Eers. In case you're interested in that one, you should be able to listen at
www.thestreamcenter.com
And you might also look into radiotime.com. WAJR is on there. Good Luck!
