JJY is the call sign of a low frequency time signal radio station.The station is located in Japan and broadcasts from two sites, one on Mount Otakadoya, near Fukushima, and the other on Mount Hagane, located on Kyushu Island. JJY is operated by the National Institute of Information and Communications Technology, an independent administrative institution affiliated with the Ministry of Internal Affairs and Communications of the Japanese government.The Mount Otakadoya site is located at an elevation of 790 meters. It broadcasts a 50 kW signal on 40 kHz from an umbrella top- loading antenna situated 250 meters above the ground.The Mount Hagane site is located at an elevation of 900 meters. It broadcasts a 50 kW signal on 60 kHz to avoid interfering with the Otakadoya site as their signals overlap. The antenna for the Hagane site is also an umbrella top loading antenna and is situated 200 meters above the ground.Both carrier signals contain an identical pulse-width modulated time code and are transmitted 24 hours a day.
