I just heard 102.5 say "WCRB-FM Waltham/Boston" (their Greater Media "voice" announcer),,I could swear I heard him say "WCRB" not "WKLB"... There may have been legal IDs 5 or 10 minutes before noon, to cover themselves...I'd have to go to the tapes I did to be sure. > Apparently the call-letter change was approved in time by the FCC.
