Broadcast of the Time From NPL (formerly MSF 60kHz Standard Frequency & Time Service) We are purchasing the service to provide, operate and maintain the MSF signal at a carrier frequency of 60 kHz. The effective radiated power of the signal shall be sufficient to provide a minimum field strength of 100 uVolts / m at a distance of 1000km from the transmitter, and shall cover the whole of mainland UK. The contractor shall provide at least 2 frequency standards able to maintain the carrier frequency at 60 kHz to within 2E-12 (2 parts in 10 to the power of 12) over a period of 30 days without dependence on off-air reception of any signal and shall provide the equipment required to generate and to monitor the correct time and date code at the Transmission Station.
