does the flag ship have to pay the fee? Is WABC owned by CC, I would have thought they are owned by ABC, but in today's world, who knows?
The El Rushbo flagship, WABC, is owned by CC rival Cumulus, which started the Huckabee show so that it might be able to replace Rush with a show they owned and could keep "all" the revenue from. Cumulus owns a number of the top market talk stations that carry Rush, including WLS in Chicago.
IIRC, when Rush started at WABC, he did a two hour local NYC talk show in trade for studio and satellite distribution services from ABC for his, just starting, nationally syndicated talk show. He was on locally from 10-AM until Noon, and did the national show starting at noon. That is how WABC got to be Rush's "flagship."
In order to avoid New York city and state income taxes, and, probably AFTRA involvement, Rush moved to Florida and built his own studio near his Palm Beach mansion. Florida has no income taxes, and is a "right-to-work" state. He used to broadcast from WABC when he visited NYC, but sold his NYC apartment in the last couple of years because the city and state were keeping track of his earnings while in NYC for tax purposes. When you work in NYC, even occasionally, you're supposed to pay city and state taxes on your earnings there and its worth it for the state and city to keep track of people like Rush with big daily paychecks.
Probably, Rush has an ISDN line from Florida to WABC, which then feeds the audio to the old ABC radio uplink facilities near Vernon Valley, New Jersey. That used to be, and probably still is, the uplink spot for the major national radio talk show feeds.
WABC production director and staff announcer, Johnny Donovan (his AFTRA name), is still the main production voice for Rush's show, but how the financial arrangements work can only be a guess. Obviously, Clear Channel could switch "Flagships" in a heartbeat, and it has the facilities to do that seamlessly in dozens of places. There are probably clauses in the WABC-Rush contract that have been there since 1988, and the contract has passed from station owner to station owner since, and they are just not worth negotiating out. Rush was an independent contractor in the very beginning, and now appears to be Clear Channel employee, so you'd probably need a good contract lawyer to tell you how it all works even if you had the contract in front of you.
Bottom line, it still costs WABC to carry Rush.
Hannity does do his show from WABC and his syndication is handled by both Clear Channel and Cumulus. IIRC, Cumulus owns the rights to the show on its own stations, and Clear Channel's Premier unit handles all other syndication.
