##### Medium Frequency (MF) Medium [[frequency]] is the [[ITU]] designation for radio frequencies ([[RF]]) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz). Part of this band is the medium wave ([[MW]]) [[AM broadcast band]]. The MF band is also known as the hectometer band as the [[wavelength]]s range from ten to one hectometers (1000 to 100 m). Frequencies immediately below MF are denoted low frequency ([[LF]]), while the first band of higher frequencies is known as high frequency ([[HF]]). MF is mostly used for AM radio broadcasting, navigational radio beacons, maritime ship-to-shore communication, and transoceanic air traffic control. >Covered in: >Mentioned in: >References: [[WP Medium Frequency|🌍]] >Required by: > >Related to:
