15Q was a station in Knoxville back in the late 1970s. It was a very good station but on a very poor under-powered AM frequency (1490).
Because it was so small (1000 watts day / 250 watts night) and on AM, it really never had a chance against WNOX (990 AM / 10,000 watts) and WRJZ (620 AM / 5000 watts). But it was surely a hot little station with some AMAZING talent for its short life. Some included Rockin' Ron Baptist, Tom Dooley, Gary Adkins, Alan Sneed, Steve West, Chuck "Boo Boo" Barron, Eddie "Swangin' Deacon" Beacon, Bill "Suitcase Simpson", Bill "Birdman" Thomas and many more. Without a doubt, 15Q was the best top-40 station in Knoxville's history. Certainly the best station with the best group of people that I ever worked for.
Because you're "knoxradiodude" I figured you would have known all about it.
