Bad call letters, Iowa edition:
KXJX, 103.3 Pella. In the early 80s, this was a pretty tight small market station that was an AC with news and Paul Harvey. Attractive bumper stickers...but those calls were atrocious! "Kay-ecks, Jay-ecks" could make even Don Pardo sound like Howard Cosell. Rumor had it that the owners at the time actually had those calls released from a Navy vessel. (Said owners redeemed themselves a few years later when they put a new FM on air in North Mankato, MN: KDOG)
WSUI-KSUI, Iowa City. I was a student announcer there (at the State University of Iowa) in the late 80s. Really, these calls aren't that bad if you enunciate properly. My PD called me on it...don't let them roll together or it comes out "double-yoo essSHOEeye"
WOI, Ames. A short stint as a student announcer at Iowa State's legacy station. (can't say I helped its legacy any) Ditto above. Should be "double-yoo oh eye" but too many of their people today roll it off as "double-yoo woe why"
And finally, the calls on any facility, whatever they are, that used to have a three-toe, such as WOW Omaha. KXNO Des Moines, the former KSO gets a pass, first they're catchy and unique for a sports outlet, plus (x + n) / 2 = S.
