Yep. They never should have given up the site near 23rd & Iowa. That was a great site for coverage. The move took KLZR out of contention for Kansas City except for overly intense people like me who would actually put up an outdoor FM antenna specifically to receive it. Bonus, though: KJHK.KCHZ was also KHUM "96 Hum FM" around 1990. As recently as 15 years ago and over a decade after it left the air, you could still see a sign on Massachusetts Street in downtown Lawrence for 96 Hum FM. I also remember KZTO "Your Total FM." Musically, it wasn't bad, but it sounded like it was saying, "Your Toto FM." It also made the mistake of trying to become a Topeka station. I get that it looked like a good decision on paper, but Topeka has always been a really tough place to make money. I think you've mentioned it before, but that Lecompton tower was a huge mistake for 105.9 by a company that rarely made mistakes.
I remember that office on Mass - KHUM lasted maybe a year or two. The 95.7 frequency was blank from roughly 1991 to 1992 then again from 1994 past 1996. It was still off the air when I left KC toward the end of 1996.
Aside: Unlike a lot of Mizzou grads, I don't have a weird disdain of Lawrence. It's a delightful college town. KU is a good university, too. I just wish KU people would be a bit less obnoxious about their sportball things.
