I was sitting in my car in New Britain, CT, this afternoon and took a spin across the FM dial. A strong signal appeared at 89.7, carrying NPR programming. I assumed it was WGBH-FM, which often puts a nice signal into this area when conditions are right, but the RDS display caused doubts. Instead of call letters and/or program info, it read "LOCALNPR". I didn't have time to wait for a station ID, so can anyone tell me if 'GBH is using this "placeholder" RDS display or was I listening to some other 89.7?
