FREQUENCY CONVERSION

A band is a group of frequencies. Sometimes, bands are grouped according to their wavelengths, in meters. The tuning location of a station can be expressed as a frequency (kHz or MHz) or a wave- length (meters).

Amateur radio operators generally refer to the frequencies they op- erate on using the frequency’s wavelength. For example, the 19- meter band refers to the range of frequencies with waves about 19 meters long.
