Old Walla Walla Radio History

Two Walla Walla radio stations had downtown business offices and studios before moving to their transmitter sites.  KUJ was well before my time and I'm not sure of the exact location, although the sign was up well after it's departure and I have faded memories of it.
I remember KTEL in the Book Nook Building (officially known as Die Brucke Building), the station would broadcast it's daytime programming downtown and it's evening and weekend programming at it's tower and transmitter site.  In the early 1970s, the station added on to it's transmitter studios and moved out of it's downtown location.
