I also heard it and recorded it at home.Don't know if they slipped a "WKOX Everett" in some time before or after top of hr;probably not.As I told someone on twitter,they can say WKOX Boston as often as they want but must give the city of license as a top of hour legal ID. "WKLB Waltham-Boston", "WCRB Lowell-Boston",as long as that COL shows up!
