MSF Outages
The MSF Annual Maintenance Periods for 2009 and 2010
The MSF 60 kHz standard-frequency and time signal, broadcast by VT Communications 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.
The dates and times of the scheduled maintenance periods for 2009 and 2010 are as follows:
From 08:00 BST, Tuesday 28 July 2009 until 18:00 BST, Wednesday 29 July 2009
The service will be restored overnight on 28-29 July if possible
- 10 September 2009 from 10:00 BST to 14:00 BST
- 10 December 2009 from 10:00 UTC to 14:00 UTC

- 10 March 2011 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 2-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.
