Specific frequency allocations vary from country to country and between ITU regions as specified in the current ITU HF frequency allocations for amateur radio. [1] The list of frequency ranges is called a band allocation, which may be set by international agreements, and national regulations. The modes and types of allocations within each ...
Review of the 88 Expanded Band authorizations made by the Federal Communications Commission on March 17, 1997. [5] In the table below: For the "Original Standard Band Assignment" entries, the FCC's March 17, 1997 notification listed station's call signs and frequencies as of June 30, 1993, dating to when the stations initially notified the commission that they were interested in participating.

Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...
In the Americas (defined as International Telecommunication Union (ITU) region 2), the FM broadcast band consists of 101 channels, each 200 kHz wide, in the frequency range from 87.8 to 108.0 MHz, with "center frequencies" running from 87.9 MHz to 107.9 MHz. For most purposes an FM station is associated with its center frequency.
The usage of frequencies within the United States is regulated by the Federal Communications Commission (FCC). When distributing initial spectrum licenses in a band the FCC divides the US geographically into a number of areas. [1] A mobile operator (or other interested party) must bid on each area individually.
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.

The 1.2-centimeter or 24 GHz band is a portion of the SHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The amateur radio band is between 24.00 GHz and 24.25 GHz, and the amateur satellite band is between 24.00 GHz and 24.05 GHz.
