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 (The segment from 2.310 to 2.390 GHz was withdrawn from the amateur service and reallocated to direct satellite radio broadcasting, e.g., Sirius XM Radio.)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.

“United States! the ages plead,—
Present and Past in under-song,—
Go put your creed into your deed,—
Nor speak with double tongue.”

“The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written.”

“I feel most at home in the United States, not because it is intrinsically a more interesting country, but because no one really belongs there any more than I do. We are all there together in its wholly excellent vacuum.”
—Wyndham Lewis (1882–1957)
“An inquiry about the attitude towards the release of so-called political prisoners. I should be very sorry to see the United States holding anyone in confinement on account of any opinion that that person might hold. It is a fundamental tenet of our institutions that people have a right to believe what they want to believe and hold such opinions as they want to hold without having to answer to anyone for their private opinion.”
—Calvin Coolidge (1872–1933)
