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 ...
FM channel numbers are most commonly used for internal regulatory purposes. The range originally adopted in 1945 began with channel 201 (88.1 MHz), or a value high enough to avoid confusion with television channel numbers, [2] which over the years have had values ranging from 1 to 83. Having a gap between the highest TV channel number and the ...
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
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.
FM audio for analog television channel 6 is broadcast at a carrier frequency of 87.75 MHz, and many radios can tune this low; full-power stations ceased analog operations in 2009 under FCC orders, but a very small amount of low-power stations are still operated solely for their right to use this frequency for broadcasting an FM audio carrier ...
