What are WARC Bands in Amateur Radio?

WARC stands for World Administrative Radio Conference. WARC bands are on 30 m (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz). These narrow bands are named after the World Administrative Radio Conference which created a worldwide allocation of these bands for amateur use. The bands were opened up for use by amateur radio operators in early 1980s. Due to the relatively small bandwidth, they are in general not used for contesting. On reciprocal note, non-contesting radio amateurs may use these bands during the largest international contests. Though the band plans for the WARC bands vary between regions, country and even the licence category, in general they follow the principle of CW at the lower end of the bands.
