I think The Wave is 94.7, if I remember correctly. I could never stand it when I lived there. Smooth, formulaic jazz. I moved out of the area in mid 1995, though, so that was ages ago.
Your right on the call numbers .. as far as the music when they switch to jazz in 85? they were unnique and I heard a lot of incredible new music on that station. Like I said I think now a days commerial but still a nice resource
