I have airchecks from KWWA from the CHR loop days--maybe. I recorded it on a low-quality K-Mart tape, and I haven't checked it in a while. I kept listening to the loop wondering when it began and ended. Whoever did this sure liked .38 Special's Tour de Force album.
I discovered KWWA when my dad car radio auto-scanned the FM dial. I had an empty preset in the wake of KYYX ending, so I filled it. And when they switched to KHIT, Stephen Raybow showed up, so it must be fate. (Then when he left, I filled in C-89, and he showed up there.) Also, Gold Mountain KHIT was the only Seattle station available at Paradise, Mt. Rainier. You could also get all the Portland FMs from there.
