Abstract: This presentation will attempt to clarify the basic principles in the design and operation of the avalanche beacon. It will deal also with the reasons for the upcoming changeover to the single frequency 457 Khz operation mode. The nature of the electromagnetic fields generated by the transmitter uni t with particular emphasis on the variation with distance from the unit and how they may be oriented will be presented. How the received signal can be used to determine information on the orientation of the transmitter even when the location is not yet determined will be shown. Of special significance is the power 1evel of the detected signal and how that is modified by the location and surroundings of the sender. From an understanding of the performance some appreciation of the current suggested modes of field use may be gained and users can then adapt their maneuvers for the best overall performance.
