The annual maintenance shutdown of the MSF service to allow safe maintenance of the masts and antennas, including greasing of the stays, will take place between 14 and 31 August 2017.
The service will be off-air from:
08:00 to 19:00 BST each day, including weekends.
If the weather is unsuitable for work to be carried out, then the service will not be turned off. If the work is completed sooner than 19:00 BST on any day, the service will be restored as soon as possible.
The MSF radio signal is a dedicated time broadcast that provides an accurate and reliable source of UK civil time, based on the NPL time scale UTC(NPL)
