MSF off the air on Thursday

The 60 kHz time and frequency standard station MSF will be off the air for 4 hours on Thursday September 10.

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 are as follows:

* 10 September 2009 from 10:00 BST to 14:00 BST
* 10 December 2009 from 10:00 UTC to 14:00 UTC

NPL say 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.

Short unscheduled breaks in transmission occur occasionally in addition to the scheduled breaks for maintenance.
NPL provides a recorded message service, tel: +44 20 8943 6493, which announces planned maintenance periods and, during working hours, prolonged unscheduled outages.
