Historically, amateur stations have rarely been allowed to operate on frequencies lower than the medium-wave broadcast band, but in recent times, as the historic users of these low frequencies have been vacating the spectrum, limited space has opened up to allow for new amateur radio allocations and special experimental operations.
The World Administrative Radio Conference (WARC) bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.1–10.15 MHz), 17 meters (18.068–18.168 MHz), and 12 meters (24.89–24.99 MHz).

By the 1980s, amateur use of 2-meter and 70-centimeter bands was at an all-time high while activity on 1.25 meters remained stagnant. [citation needed] In an attempt to increase use on the band, many amateurs called for holders of Novice-class licenses (the entry-level class at that time) to be given voice privileges on the band. In 1987, the ...
The band was defined from 1215 to 1300 MHz and was allocated exclusively for radio amateur use. In the 1979 World Administrative Radio Conference held in Geneva (WARC-79), the band was reduced to 1240 - 1300 MHz and downgraded to secondary allocation for amateur use. The primary allocation to the radiolocation service has highest priority.
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...
