Ive heard that 406 MHz homing equipment is very expensive to buy and quite cumbersome to operate. Do 406 MHz emergency beacons require 406 MHz homing equipment?
All 406 MHz emergency beacons offered for sale in Canada also include a 121.5 MHz homing signal to guide search and rescue crews into a distress site. This signal is particularly helpful in hours of darkness, or where visibility is limited by fog, precipitation, or dense vegetation. This is the same signal many search and rescue crews are currently equipped to home, and this equipment is readily available on the market. Cospas-Sarsat will stop processing 121.5 MHz signal as of February 1 2009, but this frequency can till be used as a homing signal.
