Unlike CB usage in the United States, and subsequently elsewhere in the world, the original UK 40 channels progress in order with 10 kHz spacing. These channels apply to UK-only radios meeting MPT-1320 (marked CB 27/81) [ 1 ] and MPT-1382 (marked PR 27/97, these may also feature the additional 40 CEPT channels).
Among several other services that share the CB frequencies is the former Class C Citizens Band service, renamed to the Radio Control Radio Service (RCRS) in 1976, outlined in Subpart C of the Part 95 rules for radio-controlled ("R/C") devices. No voice transmissions are permitted. It has six channels in the 27 MHz band.
Citizens band radio (CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band. Citizens band is distinct from other personal radio service allocations such ...
Examples of standardized services include PMR446 and FM Citizens Band Radio (CB) in the EU and several other countries/regions. 26–27 MHz CB radio is the oldest personal radio service and is used in nearly every country worldwide, with many countries and regions copying the United States 40-channel frequency plan. In many countries, CB radio ...
The following television stations broadcast on digital or analog channel 19 (UHF frequencies covering 500-506 MHz) in Canada: . CBFT-DT in Montreal, Quebec; CICA-DT in Toronto, Ontario
Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...
US frequency allocations chart, 2016. 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]
Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band of the 3.5 GHz band (3550 MHz to 3700 MHz) in the United States. [1] In 2017, the US Federal Communications Commission (FCC) completed a process which began in 2012 to establish rules for commercial use of this band, while reserving parts of the band for the US Federal Government to limit interference with US Navy radar ...
