19 of the COSPAS-SARSAT. The RT-600-LE has the same ability as the (A) model for 121.5 MHz and 406 MHz beacons; however, the maritime and military frequencies were replaced with ETS and LoJack frequencies. The RT-600 and its predecessor, the SAR DF-517, have


been mounted on a wide variety of rotary wing aircraft. They have been mounted on a number of fixed wing aircraft types including, but not limited to, the Maule, Cessna 172, 182, 206, DO-238, and Cessna Citations. Anyone that owns a SAR DF-517 can have their system


converted to the newer RT-600 version. The antenna housing and display remain the same which makes the conversion sim- ple as far as the customer is concerned. A conversion includes a new one-year factory warranty. Lon B. Arnold is the President of RHO-
