The buyer of 94.7 will need to move the stick to the ESB. Because of WMAS in Springfield, MA (also on 94.7), it will have to be a directional. WMAS is owned by Cumulus. If Cumulus gets 94.7 in NY, they'll put nothing into it, probably a simulcast of WABC.
Of course, there's always ESPN. WEPN could swap 1050 for 94.7. If ESPN lands on 94.7, CBS may have to consider blowing up 92.3 to simulcast WFAN. CBS-FM and Fresh will probably stay intact. Though it's not a bottom feeder, 92.3 Now is the lowest rated of CBS' NY FMs.
Stay tuned!
