Don't know why they moved it, unless they wanted fresh branding for 97.1 ("Fox 97" being too associated with 60s oldies, and "good times and eight oldies" at the end). Of course, I would think that "WFOX" would be worth a lot more to Rupert Murdoch than Anne Cox Chambers, so they had to park it somewhere to keep from giving it away. And I am sure that CC would love to have it for WRFX out of Charlotte

More odd is CC's merry-go-round of WPCH. After Lite (WLTM) came in, first it went to an AM country station in Augusta (IIRC), then 96.5 out of Gray (which is now WEBL 96.5 The Bull

after a frequency swap). WEBL was formerly 102.5 out of Warner Robins, which is now WPCH. See
