The Wrong Call Letters

How did two Pennsylvania radio stations get call letters starting with “K?” A 1923 Bureau of Navigation decision made it so that radio broadcasters east of the Mississippi would get call letters starting with “W.” Stations in the West began with “K” — except in the case of Pittsburg’s KQV and KDKA. Both opened for business prior to the 1923 ruling, marking them as two of the oldest radio stations in the country.
