Amateur Band

 

a wave band allocated for amateur radio communications (including amateur radio competitions) or for transmission of signals to radio-controlled models.

In accordance with an international treaty regarding radio communications, there are five shortwave bands assigned to amateur radio communications: 80-, 40-, 20-, 14- and 10-m wavelength bands; these correspond respectively to the frequency ranges of 3.50-3.65 megahertz (MHz), 7.0-7.1 MHz, 14.00-14.35 MHz, 21.00-21.45 MHz, and 28.00-29.7 MHz. Six ultrashort-wave bands have also been allocated, with frequency ranges of 144‣146 MHz, 430‣440 MHz, 1.215-1.300 gigahertz (GHz), 5.65-5.67 GHz, 10.0-10.5 GHz and 21‣22 GHz. The frequencies assigned for the radio control of models are 27.12 MHz ± 0.05 percent and several sections in the bands 28.0-29.7 MHz and 144‣146 MHz.

Within each amateur band, individual sections are assigned to telegraph and telephone operation and to communications with nearby and distant stations.
