KFDM stated that the Fox 4 feed will move from KBTV 4.1 to KFDM 6.3 on New Year's Day. And they're telling folks to rescan.   So many questions? Are they're going to use KBTV as a possible ATSC test station? Or will it just be a switch of networks, moving Charge to 4.1?   Still remember when Nexstar (KBTV former owner) switched affiliations from NBC to Fox almost twelve years ago (1/1/09)........
