frecuencias

Popularly known as radio bands. Frequencies are grouped according to their wavelengths, in meters. The tuning locations of a station can be expressed as a frequency (kHz or MHz) or a wavelength (meters). Amateur radio operators generally refer to the frequencies they operate on by using the frequency's wavelength. For example, the 19-meter band refers to the range of frequencies with waves about 19 meters long.
