Emergency position indicating radio beacons (EPIRBs) Emergency locator transmitter (ELT) 121.5 MHz Not Monitored When activated, each of these beacons provide a dis- tress alert to the country in which they activated and the country in which they are registered. However, all distress beacon alerts that are U.S. coded and located outside of U.S. SAR regions will be routed to a U.S. rescue coordination center. ELTs and PLBs alert to the U.S. Air Force rescue coordination center, and EPIRBs alert via the U.S. Coast Guard Atlantic Area. 6R WKH QH[W WLPH \RX ERRN D ÁLJKW ERDUG DQ DLUFUDIW or visit friends and family overseas, take a moment to consider that there are many others involved in that ÁLJKW RWKHU WKDQ WKH ÁLJKW FUHZ DQG JURXQG WHDPV It is important to note that in the aviation community, while many are converting to the digital 406 MHz SARSAT-compatible beacons, many still retain and install the older 121.5 MHz beacons. However, in February 2009, the space-based system terminated monitoring the 121.5 MHz signal. While many 406 MHz beacons retain a 121.5 MHz signal that ground rescue teams might use, the space system does not detect it. In fact, unless an aircraft flies nearby, that signal may never be heard.
