Designed to offer superior performance and reliability, the all solid-state BendixKing KDF 806 is the acknowledged standard in remote-mounted ADF systems. Incorporating “coherent detection” technology, the KDF 806 is able to select weak or distant signals with a high level of accuracy.

This capability helps reject interference and eliminate bearing errors, even during thunderstorms, to give you reliable ADF tracking. All ADF frequencies, from 190 kHz to 1799 kHz (with an option to include marine frequencies up to 2182 kHz), are generated by a digital synthesizer.
