One Frequency for Emergency Beacons
Canadian Coast Guard Search and Rescue (COSPASSARSAT) now monitors EPIRBs (Emergency Position-Indicating Radio Beacon) only on frequency 406 MHz as of February 2009. Old EPIRBs transmitting on 121.5 MHz and 243 MHz can still be used for direction finding by the Coast Guard, but should be replaced with new ones. [Emergency Beacons (Canada)]
