The end for monitoring of 121.5 / 243MHz EPIRBs

From February 1st 2009 the monitoring by satellite of distress alerts from EPIRBS broadcasting at 121.5 and 243 MHz will cease.

If a distress signal is sent by other means SAR (Search and Rescue) craft may still use the 121.5MHz frequency to locate sailors in distress but the frequency will no longer be used for the initial alert.

Monitoring by satellite will now be restricted to the new 406Mhz equipment

Further guidance is available in Marine Guidance Note 361 from the UK MCA.

EPIRBS or Emergency Position Indicating Radio Beacons are designed to automatically transmit a distress signal when immersed in the water if a boat or ship capsizes.
