Apparently, the FCC hasn't renewed WALR's license since 2011, and WSRV's since 2003, because of the pending Cox AJC cross-ownership waiver.
This particular article deals with Cox getting a (different) waiver to not have to have a (online) public file dating back to 2004 for WALR and 1996 for WSRV, based on when the licenses were last renewed.
I wonder if this has anything to do with WSRV's on-again, off-again move from the Chateau Elan tower. As I recall WALR and WSRV just miss overlapping each other with city-grade signals as is, and a further move-in by either one would cause them to overlap and increase Cox's presence in that overlap area by one station. That may no longer be the case with all of WALR's moves the last few years.
