JJY

JJY is the callsign of a longwave time signal radio station similar to WWVB. The station is located in Japan, operated by a branch of the Japanese government known as the [National Institute of Information and Communications Technology]. JJY broadcasts a 50 kW signal on 40 kHz from a transmitter site on Mount Otakadoya, near Fukushima ([37°22′N 140°51′E]), and a separate 50 kW signal on 60 kHz from a transmitter site on Mount Hagane ([33°28′N 130°11′E]), located on Kyushu Island. Both carrier signals contain an identical pulse-width modulated time code, and are transmitted 24 hours a day. The format of this time code is not the same as that used by WWVB.
