WebDescription. A non-directional beacon (NDB) is a radio beacon operating in the MF or LF band-widths. NDBs transmit a signal of equal strength in all directions. The signal contains a coded element which is used for station identification (normally 1-3 letters in Morse Code ). NDBs are often associated with Non-Precision Approach procedures. WebDirection finding(DF), or radio direction finding(RDF), is – in accordance with International Telecommunication Union (ITU) – defined as radio locationthat uses the reception of …
WebAn 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. [9] [10] ADF receivers are normally tuned to aviation or marine NDBs operating in the LW band between 190 – 535 kHz.
