If WEPN migrates to FM at 94.7 or 107.5, CBS will be faced with the possibility of blowing up an FM for a WFAN simulcast. CBS isn't going to let ESPN erode WFAN like they allowed 97.5 The Fanatic in Philly do to WIP before simulcasting WIP on FM.
Those of you who think this way need to realize two important things.
1. the WIP move in Philly had more to do with the signal issues on 610 AM, and CBS's overall sports talk-on-FM strategy, than the presence of WPEN on FM; from what I understand WIP is still ahead of WPEN in the ratings.
2. WFAN has both heritage and a very strong signal in its pocket, so having WFAN simulcasted on an FM is a waste of an FM channel. Even if CBS were to get another FM in the market (can they?), the only logical thing to do would be to use that frequency to simulcast 1010 WINS. There is absolutely NO NEED to have an FM simulcast of either of their two 50 kw clear-channel AMs -- 660 or 880 -- which covers the entire meat of the metro (and more after dark).
ESPN Radio needs to get an FM here; we know this already. 94.7 may be their very last shot. I say this because if WBLS is forcibly unloaded by Inner City whomever buys it (Radio One?) will keep it as it is. Pacifica isn't selling WBAI anytime soon, and we now know that Family Radio will not sell any of their stations to a religious broadcaster (no Salem, no EMF, etc.)
Here's another scenario for Disney/ABC: buy 94.7 and convert it into the new home of Radio Disney. Even though I despise the format it is much better suited for FM anyway. Keep ESPN Radio on 1050, with 1560 becoming ESPN Deportes.
