Big signal FM's don't come up for sale often. If CBS is looking for an eventual FM home for KYW, they'd be wise to look at it. The last thing they want to have to do is sacrifice WOGL if KYW all of a sudden starts slipping in the ratings. KYW is about the only usable thing left on the AM in most of the Philly market. Sure, it will be nice to have a national sports feed on 610, WPHT has it's audience and WDAS/1480 is a cool listen, but the vast majority of listening is on FM. And the ratings can go south at anytime. WBZ used to rule the Boston airwaves, but has recently slipped to seventh overall. CBS will have to address that situation eventually. I doubt they want to have that issue with KYW. I don't think CBS will have the room to fit another FM under the ownership caps, since they control two TV stations, three AM's and two FM's. They would have to spin off one of the AM's (610 or 1060 itself) as part of the deal most likely.
