Rocking Rob,
I wouldn't waste too much time on anyone incapable of second-grade English. (Folks, it's a discussion forum-- not a text message. The few in radio still in a position of hiring do read these boards. I know I'D never hire anyone who pluralizes words with the letter "Z", uses the numerals "2" and "4" instead of "to" and "for", and types "there" when he means "their"-- but that's just me.)
As for the simulcast rules, what is the ultimate clarification on an AM/FM within the same market? (I know an earlier postor said it was allowed, but others have said it's not.) I remember Jerry Lee running Eazy 101 on WFIL around the clock less than 20 years ago. As far as I know, there's always been a small-market exemption (obviously inapplicable to Philadelphia) that would explain how WSNJ and WSNJ-FM simulcast all those decades.
WOGL (AM) ran its own afternoon drive programming; simulcasts with the FM were limited to mornings, overnights, and weekends in the beginning. By the end in 1994, only Don Cannon was simulcast. Satellite Sports Talk (ASRN) was cleared overnights and weekends, and began to outrate the oldies themselves on what was still being called Oldies 1210. I know 1991 the midday/afternoon/early evening combination of Hy Lit, Harvey Holliday, and Bill Wright Sr. playing oldies on average a decade earlier proved a nice alternative to WOGL-FM (and managed to steal what few listeners WPGR had remaining; Pyramid would sell the station soon thereafter).
Don't forget, just two weeks or so after WCAU was killed, CBS restored Sportsline to 1210 weeknights. Steve Fredericks wasn't brought back, but Don Henderson (who had been Tony Bruno's morning sports guy toward the end of 'CAU) was. A few months later he was replaced with a relatively unknown former WAMS Wilmington personality named Scott Graham. Sportsline was quietly discontinued around 1992 and replaced with Ron Barr's syndicated show; Graham would be brought back in 1994 to do afternoons on the new WGMP with Neil Hartman and Big Daddy Graham (the latter of which was a frequent Bruno fill-in on WCAU, and had been doing some fill-in on WWDB).
Charlie Bennett is still in the area, and in addition to being on Radio Philly Style as Rocking Rob pointed out, still hosts Saturday nights at Michael's Cafe in Bensalem. I recall Mike St. John going briefly to WNJO in the late '90s, then being brought back to WOGL-FM for a short time.
There were five Oldies stations in Philadelphia in the few-year span of the late '80s/early '90s, and that doesn't count AC stations Sunny, Kiss, and Magic (which at various times during that frame were very heavy on the music themselves).
