What is MW frequency?

Sometimes a division by wavelength is used: Short wave (SW): Wavelengths of 10-200m hence frequencies of 1.5-33 MHz ; there are several sub-bands. Medium wave (MW): Wavelengths of 200-1000m hence frequencies of 300 kHz-1.5 MHz. Long wave (LW): Wavelengths > 1000m hence frequencies < 300 kHz.

The name “shortwave” originated during the beginning of radio in the early 20th century, when the radio spectrum was divided into long wave (LW), medium wave (MW), and short wave (SW) bands based on the length of the wave .

Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting . The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band.
