Citizens Band (CB) radio dates back to the 1940s. The Federal Communications Commission (FCC), which still regulates CB, took bands from the UHF band (460-470 megacycles) for personal and business communication, as well as for controlling model aircraft. That makes sense, as less expensive CB equipment offers the general public the chance to commun...
Back in the 70s, CB became very popular. There was an oil crisis when OPEC, a group of oil producing countries, declared an oil embargo. The U.S. government responded by lowering the national highway maximum speed to 55 mph. The embargo caused fuel shortages and that led to rationing, which made it difficult to locate gas supplies. That's when CB r...
The following table presents the CB frequencies, the particular wavebands at which a signal is transmitted. The next columns list the corresponding 40 CB channels and the customary uses of the channels. NOAA Weather Radio all Hazards channels. Any authorized CB radio frequency is open to all, but some have agreed-upon special purposes. For instance...
Nothing's worse than trying to tune into CB channels and only receive muffled voices mixed in with an overwhelming amount of crackling static in return. Though all CB radios have only 4 watts of transmission power (this is mandatory by the FCC), there are certain features available for these radios that can vastly improve reception of CB frequencie...
How you plan on using your CB radio as well as which channels you may be trying to tap into will be the difference in which features you'll find beneficial. These features will help anyone improve the quality of their CB frequencies: 1. RF Gain: With this feature, an operator is able to create filters so that only a strong CB radio frequency and tr...
Single sideband modulation (SSB) more efficiently uses transmitter power and bandwidth. For an in-depth explanation, refer to Wikipedia's page on SSB.
Above the band at 27.430, 27.450, 27.470, 27.490, 27.510, and 27.530 MHz are channels for the Business Radio Service. That service is part of the VHF and UHF two-way radio bands. They are reserved for commercial use by companies and educational, religious, and health institutions. The federal government has from 27.540 up to 28.000 frequencies. CB ...
Frequencies of 28.000 MHz and higher are out of the CB channel range and into the domain of licensed Amateur Radio (ham) operators who use it exclusively for Morse code. If you own a modified export CB radio (such as the Galaxy), the 19 high setting puts you at 28.085 MHz - forbidden territory. If you're talking on that frequency, you'll be very no...
CB radios can be modified for use in Amateur Radio's 10-meter range, which is legal only for licensed operators to do. CB radios approved for use in the U.S. are marked "FCC Approved." Everyone, even ham radio operators, legally are supposed to use FCC approved CB radios for channels 1-40. Even those are possible to modify, but it is more difficult...
"Freebanding" sounds exciting, a bit like the Wild West, but don't be enticed. Freebanding or "outbanding" on random frequencies or channels is a term used to describe an operator who is illegally using these frequencies or channels within the 11 meter (above or below the 10 kHz) frequency. Many of the channels outside of the 10 kHz CB radio freque...
Mar 1, 2023 · For CB radio, the frequencies range from 26.965 MHz to 27.405 MHz. Each CB radio channel corresponds to a particular frequency within this range. For example, Channel 1 corresponds to 26.965 MHz, while Channel 40 corresponds to 27.405 MHz.
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.
Apr 13, 2017 · The Citizens Band Radio Service (CBRS) is a private, two-way, short-distance voice communications service for personal or business activities of the general public. It also may be used for voice paging. It is authorized 40 channels between 26.965 MHz and 27.405 MHz.
Jun 18, 2024 · The CB Radio spectrum is broken up into 40 channels with CB frequencies ranging from 26.965 to 27.405 MHz. While these channels are open to everyone, some have commonly agreed upon purposes. Learn more about CB channels and what happens if you break the rules.
