Sorry, here goes one of those "back when I was..." posts.
Back when I was a college freshman in the late 70s in rural southern Iowa, the local FM stations weren't very good. And the good top-40 AMs like KIOA, WLS and KAAY were beginning to decline. Then one fall afternoon, I was messing with the radio in my Datsun, and there was a silent stereo carrier on 93.9 . I thought it was going to be a local station because it seemed quite strong and not very hissy. Turned out it was Iowa City's KRNA. A bunch of twenty-somethings with a little money behind them put KRNA on the air in 1975 at 93.5, a class A channel. They continued to pursue the class C channel of 93.9 for several years. And this was in the days before they considered mutual exclusivity. If you had a station at 93.5, and wanted to move to the more powerful 2nd adjacent 93.9, you'd be subject to competing applications. So KRNA was taking a big gamble pursuing 93.9. They had a good track record in their previous years on 93.5, and so they got the nod to move to 93.9. By the early 90s, they floated up to 94.1, in a Docket 80-90-fueled two station frequency swap. Anyway, what a breath of fresh air they were. A lot of really good talent got started on 93.9 KRNA back then as a top 40 station.
Today in southern Colorado, 93.9 is a translator for one of the Pueblo Radio Group stations. It was sports last week, it's oldies this week. Business as usual for them, it seems.
