United States
In the United States, the 13 cm band comprises frequencies in two segments stretching from 2.300 to 2.310 GHz, and from 2.390 to 2.450 GHz. (The segment from 2.310 to 2.390 GHz was withdrawn from the amateur service and reallocated to direct satellite radio broadcasting, e.g., Sirius XM Radio.) The segment, 2.390 to 2.417 GHz, is domestically allocated amateur radio on a primary basis, while the remainder of the band is only available on a secondary basis. It is authorized to all amateur radio licensees who hold a Technician or higher class license (US), or a Basic or higher license (Canada). The band is allocated on a shared basis with other services, and U.S. Federal Communications Commission (FCC) Rules specify that amateurs may not cause interference to and must accept interference from other services authorized by other nations, and by radio-location, fixed, and mobile stations (except aeronautical) authorized by the FCC. As in the rest of the world, US stations in the amateur service are not protected from interference caused by industrial, scientific, and medical equipment.
The bandplan published by the American Radio Relay League recommends frequencies based on intended activity in the band.

Famous quotes related to united states:
“What chiefly distinguishes the daily press of the United States from the press of all other countries is not its lack of truthfulness or even its lack of dignity and honor, for these deficiencies are common to the newspapers everywhere, but its incurable fear of ideas, its constant effort to evade the discussion of fundamentals by translating all issues into a few elemental fears, its incessant reduction of all reflection to mere emotion. It is, in the true sense, never well-informed.”
—H.L. (Henry Lewis)
“Some time ago a publisher told me that there are four kinds of books that seldom, if ever, lose money in the United States—first, murder stories; secondly, novels in which the heroine is forcibly overcome by the hero; thirdly, volumes on spiritualism, occultism and other such claptrap, and fourthly, books on Lincoln.”
—H.L. (Henry Lewis)
“In one notable instance, where the United States Army and a hundred years of persuasion failed, a highway has succeeded. The Seminole Indians surrendered to the Tamiami Trail. From the Everglades the remnants of this race emerged, soon after the trail was built, to set up their palm-thatched villages along the road and to hoist tribal flags as a lure to passing motorists.”
—For the State of Florida, U.S. public relief program (1935-1943)
“Ethnic life in the United States has become a sort of contest like baseball in which the blacks are always the Chicago Cubs.”
—Ishmael Reed (b. 1938)
