    1. SAR Direction Finder DF 517

    3. Purpose of the direction finder The SAR DF 517 modern precision direction finder was developed mainly for professional SAR (search and rescue) purposes. It has the ability to bear and analyse traditional emergency frequencies in the UHF and VHF bands, maritime radio channel 16, and the common COSPAS/SARSAT emergency signal. Because of its very short pulse length, the COSPAS/SARSAT signal bearing cannot be determined accurately using conventional direction finders. The COSPAS/SARSAT signal on 406,025 MHz is only transmitted every 50 sec (Pulse length of 400ms) This system incorporates our newly developed and patented antenna (small, rugged and wideband), as well as sophisticated bearing analysis algorithms, allowing delivery of a quick and steady indication. The direction finder was developed for working under stressful conditions such as in an aircraft, helicopter or vehicle.

    11. Using the SCAN mode while bearing COSPAS/SARSAT signals The COSPAS/SARSAT signal on 406,025 MHz is only transmitted every 50 sec (Pulse length of 400ms) The scanning mode is possible with frequencies 406,025MHz or 121,500/243,000MHz or the matching training frequencies The LS: ---:--- timer (LS meaning last signal) always displays the time since last COSPAS/SARSAT signal was received in 406.025 MHz
