The FCC is auctioning off up to 130 frequencies, one of which is for the 106.3 frequency that Valleydale Broadcasting (aka the Reynolds family) owned until WZNN's license was canceled two years ago for broadcasting from an unlicensed location. If a new station is granted for 106.3 in Maplesville (still a class A), the 106.3 translator for Calera is probably dead in the water, at least with the current facilities given in the construction permit, as FM translators are secondary service and must yield to primary service. Could the 106.3 translator slated for Calera be moved to another frequency (I'm not sure that's even possible at this point, without some "chess pieces" were moved). Not sure, but is it possible that once the station is granted, the licensee could possibly petition the FCC to relicense/move the station to Calera (or other south Shelby county city) as a class A? Here is a list of the frequencies set for auction in April, 2020.
