There's also KATS Yakima in the question of upgrading KRXY. And CFBT. Before KTTH (and KMIH previously, Hot Jamz Radio) were on 94.5, CFBT and KRXY had expanded fringe coverage areas. I remember being on the Mukilteo and Edmonds beaches with solid, loud 94.5 the Beat.
I think I only heard KATS *once*, maybe twice, in my younger years on the 'green' side of the Cascades. Even at 100,000 watts, the Cascades blocked it all, minus KPQ-102.1 and hints of KXLE-95.3. If I were to head back to Thrashers Corner and Canyon Park, I wonder if I'd still pull in KPQ? Or is that Seattle University LP (or whatever) too strong?
