I'll try to make this story as short as possible: KCIV(Roman numerals for "104")began broadcasting in 1968 with Classical music. I visited there sometime in the late 70s or early 80s. The owner was the only announcer and lived there with his 90+ year-old mother. He was on the air from something like 7AM til after 10, six days a week and went into town on Sundays. All announcements were done live. There were no cart machines. He employed one salesman in town. This went on until he sold the station and it became KMCQ(mid Columbia) in 1982.That 'mountain' was likely Stacker Butte where KACI 93.5 and KYYT 102.3 are located. There's about a 2mi pipeline on I-82 just below the Manastash Ridge heading south where they come in well.
