Probably true.
In any case, deleting the WTKY license wouldn't free up the channel. It would remain in the FM Table of Allocations, and sooner or later it would be auctioned to some other applicant. WQQK would be required to protect the vacant allotment in the interim.
A quick check suggests WQQK *could* be upgraded to C3 (roughly 4x increase in power) if they moved about 8 miles to the south. They've got a fair bit of leeway until they run into the 92.1 station down by the Alabama line. Actually, the big problem for a WQQK upgrade is not WTKY, but WAPX at Austin Peay in Clarksville. 92Q is 8 miles too close to WAPX to upgrade to class C3.
Now, I haven't done the math on the city-grade contour but suspect WQQK couldn't provide a city-grade signal across Goodlettsville from a site that far south. They'd have to change the city-of-license, and then get some other station to change *its* city to Goodlettsville. Luckily, WSM-FM would probably do the trick.
Now, I can assure you Cumulus has engineers who are far better than I at spectrum allocation! I think one can assume, from the fact that 92Q hasn't already been upgraded, that either:
- I missed something and an upgrade really wouldn't be that easy, or:
- They agree it's possible but have decided it isn't $$ worth the effort.
