20-meter band
In-game article clicks load inline without leaving the challenge.
The 20-meter or 14-MHz amateur radio band is a portion of the shortwave radio spectrum, comprising frequencies stretching from 14.000 MHz to 14.350 MHz. The 20-meter band is widely considered among the best for long-distance communication (DXing), and is one of the most popular—and crowded—during contests. Several factors contribute to this, including the band's large size, the relatively small size of antennas tuned to it (especially as compared to antennas for the 40-meter band or the 80-meter band) and its good potential for daytime international operation even in unfavorable propagation conditions.
History
The Third National Radio Conference was responsible for opening up the 20-meter band to amateur radio operators in the US on October 10, 1924. The band was allocated on a worldwide basis by the International Radiotelegraph Conference in Washington, D.C., on October 4, 1927. Its frequency allocation was then 14–14.4 MHz. The allocation was reduced to 14–14.35 MHz by the International Radio Conference of Atlantic City, New Jersey 1947.
