Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz (30 000 kHz). Listeners range from casual users seeking international news and entertainment programming, to hobbyists immersed in the technical aspects of long-distance radio reception and sending and collecting official confirmations that document their reception of remote broadcasts (DXing). In some developing countries, shortwave listening enables remote communities to obtain regional programming traditionally provided by local medium wave AM broadcasters. In 2002, the number of households that were capable of shortwave listening was estimated to be in the hundreds of millions.
Shortwave broadcasting in the United States allows private ownership of commercial and non-commercial shortwave stations that are not relays of existing AM/MW or FM radio stations, as are common in Africa, Europe, Asia, Oceania except Australia and Latin America. In addition to private broadcasters, the United States also has government broadcasters and relay stations for international public broadcasters. Most privately owned shortwave stations have been religious broadcasters, either wholly owned and programmed by Roman Catholic and evangelical Protestant charities or offering brokered programming consisting primarily of religious broadcasters. To better reach other continents of the world, several stations are located in far-flung US territories. Shortwave stations in the USA are not permitted to operate exclusively for a domestic audience; they are subject to antenna and power requirements to reach an international audience.
