Not one of those listeners in "the Midwest, Northeast and Southeast" will do a thing for WWKB's "ratings success" unless their home address is in Erie or Niagara counties and they're carrying an Arbitron book. The signal may go all over the place, but the only numbers that matter to Entercom's bottom line are the local ones in Buffalo.
What WWKB does - and the only thing that WWKB does - is to provide some overflow for WGR programming, to keep ESPN away from any other player in the market, and (as it has been for 15+ years now) to make sure nobody else can use the 1520 facility to compete with WGR and WBEN. That's it. That's all it is. That's all it will ever be so long as the Entercom cluster exists.
