Taken from reference: 1 An example of a dual frequency beacon model used in Canada, this device was in used by the Parkland Cross Country Ski Club of Red Deer Alberta as part of a fleet of rental devices to club members. http://www.parklandxcskiclub.org/

Fonction

An avalanche rescue beacon (radio transceiver), is a radio transmitter-receiver device used to detect people buried in snow. This analog device broadcasts a pulsed signal as an audible tone which is picked up by users with other beacons and heard wearing the supplied earphone.

Technique

Taken from reference: 1 This dual frequency beacon also operates at two frequencies; 2.275 kHz, and 457kHz. “Introduced in 1980, Gerald Kampel and Jürgen Wegner develop the first double frequency transceiver, ORTOVOX F2 for searching avalanche victims. Until then all avalanche transceivers in use would send and receive in different frequencies (2, 275kHz or 457 kHz). This would often lead to fatal avalanche accidents when victims could not be found quickly enough due to differences in frequency. The F2 can send and receive on both frequencies and is received with enthusiasm. Within 2 years of its introduction it became number one on the market”. Source: http://www.ortovox.com/3146--history.html The standard of 457kHz was adopted in 1986 by the International Commission on Alpine Rescue (IKAR), in 1996 by the American Society for Testing and Materials (ASTM), and also by the American National Standards Institute (ANSI).
