Post War Era
In 1947 the uppermost 300 kHz segment of the world allocation of the 10 meter band from 29.700 MHz to 30.000 MHz was taken away from amateur radio.
During the 1950s, hams helped pioneer the use of single-sideband modulation for HF voice communication. In 1961 the first orbital amateur radio satellite (OSCAR) was launched. Oscar I would be the first of a series of amateur radio satellites created throughout the world.
Ham radio enthusiasts were instrumental in keeping U.S. Navy personnel stationed in Antarctica in contact with loved ones back home during the International Geophysical Year during the late 1950s.

Famous quotes containing the words post, war and/or era:
“My business is stanching blood and feeding fainting men; my post the open field between the bullet and the hospital. I sometimes discuss the application of a compress or a wisp of hay under a broken limb, but not the bearing and merits of a political movement. I make gruel—not speeches; I write letters home for wounded soldiers, not political addresses.”
—Clara Barton (1821–1912)
“You went to meet the shell’s embrace of fire
On Vimy Ridge; and when you fell that day
The war seemed over more for you than me,
But now for me than you the other way.”
—Robert Frost (1874–1963)
“This, my first [bicycle] had an intrinsic beauty. And it opened for me an era of all but flying, which roads emptily crossing the airy, gold-gorsy Common enhanced. Nothing since has equalled that birdlike freedom.”
—Elizabeth Bowen (1899–1973)
