DIZ was an earlier, often used time signal transmitter in the East German Nauen near Berlin. He was transmitting on shortwave 4525 kHz. The callsign from 1980 was Y3S.
The major radio station in Nauen was founded in April 1906 by a Telefunken engineer as the world's first transmitter . As early as 1916/17 it was sending a time signal twice a day for various institutes and the astronavigation of the war and merchant navy. The Nauen time signal was broadcast on long wave 3900 meters (77 kHz) and could be used throughout Europe and the North Atlantic. Around 1935 the transmitter was switched to shortwave 4525 kHz and received the call sign DIZ.
After being destroyed at the end of the war in 1945, the station went back on the air in 1955/56. It now sent the seconds points with around 5 kilowatts in 24-hour continuous operation; the minute identification was a long line at the second zero. The time signal was controlled by the Geodetic Institute Potsdam . In the 1990s, the time signal was switched off after the expansion of the DCF77 transmitter near Frankfurt / Main.
