CBS has flipped its Chicago version of Fresh to a simulcast of WBBM-AM 780, the market-leading station which runs an all news format. But Chicago's Fresh was a lot weaker performer than New York's so the two situations aren't necessarily analogous. That's probably just a temporary stunt to mess up Merlin's rollout of spoken word programming in Chicago anyway. They're likely to try something else to bring a new revenue stream back on line as soon as they've done whatever damage the similcast is likely to do to Merlin's plans. WBBM needs no help. In New York, WCBS and WINS need no help from a simulcast either, and since the FM stations in the CBS cluster are all profitable they won't be asking for it. (WCBS-FM in particular is safe, since you never kill the #2 station 6+ in any market, especially when it skews 35-54 and beats up its competition in workplace listening.)
