No, that's an urban legend. Indeed, an early Westinghouse broadcasting
station was (and still is) KDKA Pittsburgh, the only survivor from a brief
period when all stations, east or west, were being assigned KD-- call signs.
In 1913 the international callsign system was set up, and the U.S. was
randomly assigned K, N, and W (N was reserved for U.S. government use).
