"Has anyone applied to go non-commercial.
THAT is the big matching question."
It happens all the time on the AM band, occasionally on FM, and even occasionally on TV. Rochester, NY's main NPR affiliate is an AM station that went non-profit, same with Buffalo's noncomm classical FM (which was once a commercial station under a prior ownership) and even Buffalo's longtime PBS TV station was once commercial in the 1950s as an NBC O&O.
If WBAI goes commercial it's not that difficult, any more than WNSH, the onetime religious noncomm which is now Cukmulus' country FM in the NYC market. The 99.5 channel, like 94.7, is essentially a commercial FM frequency and was a commercial station from 1948 to 1960 before Pacifica owned it, both under the WBAI callsign and earlier as WABF. If they change hands and go from nonprofit to for-profit all they need to do is make sure it sells to a qualified commercial licensee without any serious financial or legal issues against it.
The interesting questions are;
1)Who is WBAI going to be sold to, and when? It'll fetch a pretty penny for Pacifica, because just the stick value of a full market class B transmitting from ESB has to be $75 million+. But it probably won't be any of the maret's current major players since they're not in the buying mood right now. Maybe some new player in the market may be looking for an entry point. Maybe that's the station that could replace WCBS as the Yankee flagship, assuming the Steinbrenners have a clue as to what to program when the ball club isn't playing.
2)What will the new owner do with it, especially if it isn't the Steinbrenner family? Now that country's taken, all-news staged a recent and expensive flop on FM, and conservative talk, sports talk and various flavors of AC and UC are in a state of surplus in the market, only local personality-driven talk like WMCA and WABC used to be is left among the obvious wide-appeal formats. The only other niche formats that are missing are pop standards (doubtful) and maybe a show business talker along the lines of a radio version of the E! channel, something which Blink 102.7 and that brief faux format "Chocolate 101.9" sort of danced around but never turned into a full-fledged format.
3)Will Pacifica find either a rimshot FM, a noncomm license like WNYE that the current operator finds more trouble than it's worth, or a struggling AM signal above 1130 and below 1560, to call home (presumably at a deep discount over what it collects for WBAI)?
This doesn't look like an April Fool's joke, simply because Pacifica is really up against it financially and has been mentioned as a possible sale/downgrade candidate for the last three months. Of course it coukd be an April Fool's joke that turns into reality...
