Termination of 121.5/243 MHz Service:
In October 2006 the Cospas-Sarsat Council confirmed that satellite
processing of 121.5/243 MHz beacons will terminate on 1 February 2009.
Beginning in 2009, only 406 MHz beacons will be detected by the Cospas-Sarsat satellite system.
This affects all maritime beacons (EPIRBs), all aviation beacons (ELTs) and all personal beacons (PLBs).
