This report contains the results of technical tests performed on a feasibility model of a dual-frequency VHF/UHF Search and Rescue Radio Beacon (SRRB) loaned to the Federal Aviation Agency by Granger Associates of Palo Alto, California. The SRRB was tested at the National Aviation Facilities Experimental Center and at sea off the New Jersey coast, with the asistance of the U. S. Coast Guard, to investigate equipment performance and to evaluate two types of carrier modulation (constant and swept-tone) specially incorporated in the SRRB provided for test. Results of the tests indicated that the concept of a dual-frequency SRRB is feasible for search and rescue operations, that its use would increase the number of search aircraft now available to include all operational military aircraft, and that the swept-tone modulation is most desirable for this application.
