Commandant (G-OTM) has been conducting a Study of Altering and Locating Techniques and Their Impact (SALTTI). One of the techniques investigated was the Emergency Position Indicating Radio Beacon (EPIRB), a self-contained radio transmitter which broadcasts a distress signal to both alert a search and rescue force and to guide that force to the distress scene. Candidate EPIRBs can operate on many different frequencies (2182 kHz, 121.5 MHz, 243 Mhz, etc.), and thus have widely varying characteristics, such as physical size and transmitting range. In 1975 a number of representative, commercially available 2182 kHz EPIRBs were evaluated by the Coast Guard. Test results presented in this paper lead to the conclusion that no EPIRB evaluated meets U.S. needs in the Coastal confluence zone. Further, characteristics of 2182 kHz communications requires excessively large antennas and/or primary power supplies to achieve a reasonable propagation range.
