Keep in mind that the ORIGINAL WFLA (AM) in Tampa is a Clear Channel property. That station's News/Talk format is the genesis of the "WFLA" brand that CC has rolled out across the state, including Panama City.
I'd say it's a pretty safe bet (understatement?) that CC/PC has an "agreement" to allow it to use the "WFLA" brand.
As a previous poster noted, the legal calls for 94.5 are "WFLF-FM/Parker," which airs once per hour. They could call themselves "Snot Radio" as long as they use the legal ID once an hour.
And knowing the history of the formats on that frequency over the years, it wouldn't surprise me to find out they actually used that moniker at one time or another.
