中频中频（MF，Medium Frequency），频段由300kHz 到 3000kHz，多数作AM电台。 比中频略低的是低频（LF），比中频略高的是高频（HF）。 在日间时，发送距离较短；但是到了夜间时间可以利用电离层反射信号，可以作远距离传信。但是较容易和其他电台的信号混杂一起，影响接收。 无线电波名 极低频 超低频 特低频

Medium frequency 中频   Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kHz to 3 MHz. Part of this band is the medium wave (MW) AM broadcast band. The MF band is also known as the hectometer band or hectometer wave as the wavelengths range from ten to one hectometer (1,000 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 and maritime ship-to-shore communication.
