MSF Outages
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.
Change to scheduled maintenance periodPlease note that the MSF 60 kHz time and frequency signal broadcast from Anthorn Radio Station originally scheduled for: 10:00 UTC until 14:00 UTC on Thursday 14 March 2013 will not now be required as the planned work was carried out during the shutdown for emergency maintenance on 1 February. As a result there will be no interruption to the service on 14 March. |
The dates and times of the forthcoming scheduled maintenance periods are as follows:
- 13 June 2013 from 10:00 10:00 BST to 14:00 BST
- 12 September 2013 from 10:00 BST to 14:00 BST
- 12 December 2013 from 10:00 UTC to 14:00 UTC
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 July or August 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.
