ADF ( AUTOMATIC DIRECTION FINDER) ✅️ADF is a marine or aircraft radio-navigation instrument that automatically and continuously displays the relative bearing from the ship or aircraft to a suitable radio station. ADF receivers are normally tuned to aviation or marine NDBs (Non-Directional Beacon) operating in the LW band between 190 – 535 kHz. Like RDF (Radio Direction Finder) units, most ADF receivers can also receive medium wave (AM) broadcast stations, though these are less reliable for navigational purposes. ✅️ .AN ADF indicator with a fix azimuth dial. The airplane is flying a 40° magnetic heading, while the station is 310° relative to the plane (called "relative bearing"). The magnetic bearing to the station in this case is 350°.✈️✈️✈️
