Audio Sample
RBU is a time code radio station located in Moscow. It transmits a continuous 10 kW time code on 66⅔ kHzKiloHertz (kHz) 10^3 Hz.

There are 2 main tones AMAmplitude Modulation modulated onto sidebands, 100 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). and 312.5 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz).. 100 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). denotes a "0" bit, whereas 312.5 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). denotes a "1". These are used to sync clocks and give the exact time.
