938 Series Civil DF
938 Series Civil DF
The 938 Series of civil Direction Finders (DF) provide a range of integrated DF solutions for bus-controlled and stand-alone direction finding systems. 938 DFs include an integral synthesised receiver covering the frequency range 88 MHz – 470 MHz, together with 5 Guard Receivers to monitor pre-defined distress frequencies. Bearings may be taken on all 6 receivers simultaneously. Data decoding is provided for COSPAS‑SARSAT messages and for marine DSC messages on the associated Guard Receivers. There is also the option to output On Top Position Indication (OTPI).
