[edit] Frequency usage

These transmitters transmit time information on 25 kHz on a specific schedule. Additional synchronisation signals are transmitted on 20.5 kHz, 23 kHz, 25.1 kHz and 25.5 kHz. These transmitters are also used at times when no time signals are being transmitted to send other coded information.
