Y3S

Y3S was the callsign of an East German time signal station. The station was operated by the Measurements and Standards Service of the DDR ^[1] in Berlin. The transmitter was located at Nauen Transmitter Station.

The station transmitted in the HF band on 4525 kHz with 5 kW.^[2] The transmission consisted of second pulses of 100 ms duration. Minute pulses were 500 ms long. Minute and hour information was transmitted in BCD code by modifying pulses of seconds 41 to 55.
