[QUOTE="Cranky Emu, post: 627253, member: 10949"] Exactly right, both EPIRB and PLB's use the same technology (save water immersion activation and float free) and frequencies as each other. Both have a homing signal on 121.5 which is the IAD to allow for planes/helis to assist in location. This is low power, I think around 500mw and with an untuned antenna they don't have a staggering range, about 1km, maybe a bit more in open terrain. The other freq being 406MHz and received by the COSPAS-SARSAT/GeoSAR satellite systems. Due to orbiting issues and to overcome delays (polar orbiting), the COSPAS-SARSAT birds have repeaters as well. Once received your distress alert is passed to the nearest RCC authority. [/QUOTE]
