Late 20th Century
At the 1979 World administrative radio conference in Geneva, Switzerland, three new amateur radio bands were established: 30 meters, 17 meters and 12 meters. Today, these three bands are often referred to as the WARC bands by hams.
During the Falklands War in 1982, Argentine forces seized control of the phones and radio network on the islands and had cut off communications with London. Scottish amateur radio operator Les Hamilton, GM3ITN was able to relay crucial information from fellow hams Bob McLeod and Tony Pole-Evans on the islands to British military intelligence in London, including the details of troop deployment, bombing raids, radar bases and military activities. However, radio hams usually avoid controversial subjects and political situations and discussions as a part of the code of politeness of radio communications.
Major contributions to communications in the fields of automated message systems and packet radio were made by amateur radio operators throughout the 1980s. These computer controlled systems were used for the first time to distribute communications during and after disasters.
American entry-level Novice and Technician class licensees were granted CW and SSB segments on the 10 Meter Band in 1987. The frequency ranges allocated to them are still known today throughout much of the world as the Novice Sub Bands even though it is no longer possible to obtain a Novice class license in the US.
Further advances in digital communications occurred in the 1990s as Amateurs used the power of PCs and sound cards to introduce such modes as PSK31 and began to incorporate Digital Signal Processing and Software-defined radio into their activities..

Famous quotes containing the words late and/or century:
“No such sermons have come to us here out of England, in late years, as those of this preacher,—sermons to kings, and sermons to peasants, and sermons to all intermediate classes. It is in vain that John Bull, or any of his cousins, turns a deaf ear, and pretends not to hear them: nature will not soon be weary of repeating them. There are words less obviously true, more for the ages to hear, perhaps, but none so impossible for this age not to hear.”
—Henry David Thoreau (1817–1862)
“The United States is just now the oldest country in the world, there always is an oldest country and she is it, it is she who is the mother of the twentieth century civilization. She began to feel herself as it just after the Civil War. And so it is a country the right age to have been born in and the wrong age to live in.”
—Gertrude Stein (1874–1946)
