MSF Scheduled Maintenance Periods
The MSF 60 kHz standard-frequency and time signal, broadcast by Babcock on behalf of NPL, is occasionally taken off-air to allow maintenance work on the masts and antennas at Anthorn Radio Station to be carried out in safety. This means that your radio-controlled clock will not be picking up the MSF signal, so may not be working correctly.
The dates and times of the forthcoming scheduled maintenance periods are as follows:
- 9 March 2017 from 10:00 to 14:00
- 8 June 2017 from 10:00 to 14:00
- 14 September 2017 from 10:00 to 14:00
- 14 December 2017 from 10:00 to 14:00
The shutdowns will take place between 10:00 and 14:00 UTC in December and March, and between 10:00 and 14:00 BST in June and September.
The duration of each outage period will be kept to a minimum, and the signal may be back on-air prior to the times given above.
In addition to these dates, the signal is likely to be taken off-air for a two-day period during spring or summer each year, remaining off-air overnight. The dates of this longer outage will be announced on this page and by e-mailed notices to registered users as soon as they are known.
If you wish to be kept informed about planned outages, please complete and submit the E-mailed Notifications of Scheduled Maintenance Periods form.
