DXing, taken from DX, the telegraphic shorthand for "distance" or "distant", [1] is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens band radio or other two-way radio communications.
Since 1953, radio amateurs have been experimenting with lunar communications by reflecting VHF and UHF signals off the Moon. Moonbounce allows communication on Earth between any two points that can observe the Moon at a common time. [7] Since the Moon's mean distance from Earth is 239,000 miles (385,000 km), path losses are very high.
Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the first digital data mode.
A DX-pedition is an expedition to what is considered an exotic place by amateur radio operators and DX listeners, typically because of its remoteness, access restrictions, or simply because there are very few radio amateurs active from that place. This could be an island, a country, or even a particular spot on a geographical grid.
Beginning with Sweden Calling DXers on Radio Sweden in 1948 [14] (there was a slightly earlier short-lived program from Radio Australia), many shortwave radio stations began programs providing news. Some of the other prominent DX programs were Radio Netherlands' DX Jukebox (which became Media Network ), the SWL Digest on Radio Canada ...
MW DX, short for mediumwave DXing, is the hobby of receiving distant mediumwave (also known as AM) radio stations.MW DX is similar to TV and FM DX in that broadcast band (BCB) stations are the reception targets.
The National Radio Club (NRC) is a non-profit hobbyist organization in the United States focused on the pursuit of DXing on the AM broadcast band. The group was founded in 1933 as a result of merging several regional radio clubs. The NRC produces a magazine, DX News, which is issued 20 times annually. The club has also authored numerous books ...
A QSL card is a written confirmation of either a two-way radiocommunication between two amateur radio or citizens band stations; a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station; or the reception of a two-way radiocommunication by a third party listener.
