For at least 15 years now (probably longer, my memory fails me on this one ;D), nothing but dead air.
From 1978 through (most of) the '80s, KQCA Canton, MO. The only station actually located in our small, rural county, complete with studio only marginally larger than an outhouse, located on a dead-end road (very American Graffiti-esque :

).
Started out playing "progressive" rock, went Top 40 by the time I was in high school, started getting its as* kicked by competitor station in Quincy and switched to 50's & 60's oldies by the late 80's. Here's where my memory starts to fade. I believe the franchise was bought out, retooled to hard rock, rechristened KRRR, and moved to 100.9, all sometime in the early '90s. For somewhat over a decade now, it's been Top 40 KRRY 100.9, with the branding "Canton, Quincy, Hannibal", and studios in Quincy. This is the last remnants of our beloved "KQ-102" of a quarter century ago :-\
We'd be out partying, and drive up there to BS with the DJs and request songs, which they would usually play. Life was simpler then, in more ways than 1.....
If anybody who reads this has more info on KQ-102, please share. Feel free to dispute me on the facts I listed, that's the way I remember it ;D
