>From the NPL: Annual maintenance: 3–21 September 2018 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 3 and 21 September 2018. The service will be off-air from 08:00 to 18:00 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 18:00 BST on any day, the service will be restored as soon as possible. http://www.npl.co.uk/science-technology/time-frequency/products-and-services/time/msf-outages Question to time-nuts: could you manage with a daytime outage of WWVB for over two weeks? Haven't heard many UK folk complaining during previous maintenance periods.
