They are also useful in base stations where circumstances preclude the use of a ground-plane antenna. Al Gross established the Citizens Radio Corporation during the late 1940s to manufacture classB handhelds for the general public. The Citizens Band, a particular square of radio frequencies (27 MHz or 11 meters) separate from TV and different signs, was made during the 1940s to serve the overall population. Russia uses an alphanumeric designation for their CB channel plans, because several "grids" or "bands" of 40channels each are used, along with both AM and FM mode. The Coast Guard stopped this practice in the late 1980s and recommends VHF Marine Band radios for boaters.[13]. Some countries also have personal radio services in the UHF band, such as the European PMR446 and the Australian UHF CB. "Export radios" are sold in the United States as 10meter Amateur Radio transceivers. What are the freeband CB frequencies? Initially, the FCC intended for CB to be the "poor man's business-band radio", and CB regulations were structured similarly to those regulating the business band radio service. Initially, CB channels13 remained allocated to amateur radio and channel23 was used by paging services. For instance, channel19 shifted two bands up is 28.085MHz, which is in a Morse code / data-only part of the 10meter ham band. Here we have collected some links to building instructions for 11m antennas on the Internet. The 27MHz frequencies used by CB, which require a relatively long aerial and tend to propagate poorly indoors, discourage the use of handheld radios. Even low-power 27MHz signals can sometimes propagate over long distances. The rules regarding non-approved radios and power levels above 4Watts on AM/FM and 12Watts on SSB still apply, despite deregulation. [31] This includes a new UHF PMR 446MHz allocation: an eight-channel analog Personal Mobile Radio 446MHz (Analog PMR446) with frequencies from 446.00625 to 446.09375MHz (12.5kHz spacing) FM with 0.5watt power output, and 16channels for Digital Personal Mobile Radio 446MHz (Digital PMR 446). However, I was listening to a guy on the CB and he said he was a trucker and was using a 10 meter amplifier. While a SSB radio has three possible "modes" (AM, LSB, USB) it can operate in, operation is still limited to the same 40channels. Instead of 2627MHz, Japan has authorized several UHF FM CB-type personal radio services in the 348MHz, 420422MHz and 903904MHz bands. Majority of countries require no license to operate the radio service. A dipole inside a loft. A typical citizen band radio service is a two-way radio system that can be used for personal or business communication. Where a nine-foot whip is undesirable, shorter antennas include loading coils to make the antenna impedance the same as a physically longer antenna. Generally the CB band is band "D" or the "mid band". Several people had 22A, but few had 22B. Most contemporary radios built for those markets can do "fives" as well as "zeroes" out of the box. Being an 8-watt power output cb, the AnyTone offers more power compared to your standard 4-watt CB. Germany authorizes a similar allocation, with 40channels from 26.965 to 27.405MHz and another 40channels from 26.565 to 26.955MHz in regular 10-kHz steps. Only 23channels were available at the time; the first 22 were taken from the former amateur radio service 11-meter band, and channel23 was shared with radio-controlled devices. for RadioShack stores in the mid-1990s. This causes interference to the authorized low-power 1Watt DSB (1Watt AM) fishery radio service. [26] In April1977, the service was expanded to the same 40channels as the American service. Most offenders are not caught for interfering with other CB users; often, their selfmodified equipment generates harmonics and spurs which cause interference to services outside the citizens band and to consumer equipment. Operation on frequencies above or below the citizens band (on the "uppers" or "lowers") is called "freebanding" or "outbanding". With these factors in play, CB radio has once again gained popularity in recent years, an uptick not seen since the 90's. Frequency selection resembles that of modified American CBs more than any foreign frequency plan. A fullwave antenna on the 11 meter band is 36 foot long but I have never once heard of anyone using a fullwave on the 11 meter band. A look at the Amateur Radio (HAM) Bands: LF Bands: Low Frequency LF is the International Telecommunication Union (ITU) designation for radio frequencies that fall between 30-300 kHz. Other Australian cities which became CB radio "hotspots" were Seymour, Benalla, Holbrook and Gundagai, all located on the busy Hume Highway between Melbourne and Sydney. After the 1973 oil crisis, the U.S. government imposed a nationwide 55 mph speed limit, and fuel shortages and rationing were widespread. FM operations in the 10 meter Amateur Radio Service band are mainly conducted on the spectrum between 29.5~29.7 MHz. Many users of handheld radios (families, hunters and hikers) have moved on to 49MHz and the UHF Family Radio Service; those needing a simple radio for professional use (e.g., tradesmen) have moved on[citation needed] to "dot-color" Business Band radios and the VHF Multi-Use Radio Service. In Japan, the 2628MHz range is allocated to fishery radio services and these frequencies are heavily used for marine communications. Starting in October 2021 the FCC has approved FM for CB in the US. I'm 37 years old and have own a lot of deffrent ground plan antennas. Packet radio is legal in the UK, although not widely used. not interested in exports . Since the band is right below the 10-meter ham radio band, most HF Ham radios will be able to receive these signals. What the CB community generally refer to as the 11m band or freeband is considered to cover is 25 MHz to the beginning of 28 MHz although most activity happens around 26-28 MHz. In the Philippines, up to present time, the use of 27MHz CB is still banned since the Marcos regime banned it in 1980s.

The 11 meter band is used by both CB radio, as well as freeband unlicensed hobbyists, Church radio broadcasts in Ireland and elsewhere in Europe, the military, for studio-to-transmitter links (STLs), data links, buoys, fishnet tracking systems, pagers and other non-voice purposes. Ultra-high frequency (UHF) radios, at the time, were neither practical nor affordable for the average consumer. He appeared in an interview (with clips having fun talking to children on his home CB radio station) in the NBC Knowledge television episode about CB radio in 1978. Before CEPT, most member countries used a subset of the 40U.S. channels. By the late 1960s, advances in solid-state electronics allowed the weight, size, and cost of the radios to fall, giving the public access to a communications medium previously only available to specialists. shortwave) band. The original 11 meter amateur radio allocation was 26.96 MHz to 27.23 MHz and it was from this that the original Class D CB service was born. In many countries, CB operation does not require a license, and (unlike amateur radio) it may be used for business or personal communications. In the U.S., the Citizens Band is composed into 40 radio channels, each assigned by a number from 1 to 40. . For example, (C9EF, C9F, C9RF), end the used modulation (FM) or (F), (AM) or (A). Citizens band radio (also known as CB radio ), used in many countries, is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating on 40 channels near 27 MHz (11 m) in the high frequency (a.k.a. On UHF 477MHz, citizens band PRS radio devices are allowed 5 watts power output on FM on 39assigned channels spaced at 12.5kHz intervals from 477.0125 to 477.4875MHz. HB9CV - 2 Element Yagi for the 11 meter band. Early receivers did not cover all the channels of the service; channels were controlled by plug-in quartz crystals, with one of several operating frequencies selected by a panel control in more expensive units. The radio is normally in receive mode to receive transmissions of other radios on the channel; when users want to talk they press a "push to talk" button on their radio, which turns on their transmitter. CB radios have a range of about 3 miles (4.8km) to 20 miles (32km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances. [7], Their use spread further into the general population in the US in the middle of the 1970s. The Indonesian government legalized CB on 6October 1980 with a decision by the Minister of Communications, the "Ministerial Decree on the Licensing for the Operation of Inter-Citizens Radio Communication". New Zealand authorizes use of their New Zealand specific 40channel 26.33026.770MHz frequency plan in addition to the "standard" 40channel 26.96527.405MHz frequency plan for a total of 80HF CB channels. e.g. [6] There are several other classes of personal radio services for specialized purposes (such as remote control devices). The loading coil may be on the bottom, middle, or top of the antenna, while some antennas are wound in a continuously-loaded helix. The use of these radios within the Amateur Radio Service by a licensed Amateur Radio operator within his / her license privileges is legal, as long as all FCC regulations for Amateur Radio are followed. The most common description of the channel is considered to be similar to the following: (C9FM or C9EFM or C9EF or 9EF). The General Radio Service was authorized in 1962. The citizens band radio service originated in the United States as one of several personal radio services regulated by the Federal Communications Commission (FCC). Superheterodyne receivers (using one or two conversion stages) were the norm in good-quality equipment, although low-cost toy-type units used super-regenerative receivers. Channel9 was officially reserved for emergency use by the FCC in 1969. Lax enforcement of the rules on authorized use of CB radio led to widespread further disregard of the regulations (such as for antenna height, distance communications, licensing, call signs, and transmitter power). Further information: High frequency beacon, Part 15 beacons - 22m and 11m bands, and Part 95 Class C RCRS type systems that operate as de facto beacons on the six 26-28 MHz RC frequencies 26995, 27045, 27095, 27145 and 27255. 2200 Meters When it comes to Ham Radio, the only official LF band is 2200 meters. Feel free to cut and paste this list into your favourite word processing or DTP software and produce a chart in any format you like to help whilst DX'ing. The regulations called for one licence per CB radio. In general, each channel can only support one AM conversation and no others; if no AM conversation is in progress, two SSB conversations can share one channel without interference if one is in LSB and the other in USB mode. HamSphere is a shortwave simulation. A common mobile antenna is a quarter-wave vertical whip. The increased use of CB radios in 1970s had made its way into films, television, and music by the late 1970s. An unsuccessful petition was filed in 1973 to create a CB ClassE service at 220MHz, (part of the amateur radio 1m band at the time) which was opposed by amateur radio organizations and others. It covered hobby radio as well as CB. For these bands, the gain is lowered so that the antenna covers a larger bandwidth. At that time in Australia, licensed ham operators and Emergency Services still used the 11 meter band[17] which was not yet available for CB use. Freeband 11 Meter Frequencies and Bands While some export radios - sold as 10 meter radios - often cover frequencies above and below the 25.615-28.305 MHz range, that is the de facto "standard" export band alphanumeric plan. CB Radio information on 11-Meters Band at 27Mhz. Before it was banned, they use the same allocation as the US. To achieve this effect, the antennas must be separated by about eight feet, only practical on large trucks. The business band requires an FCC license, and usually results in an assignment to a single frequency. Such an array is intended to enhance performance to the front and back, while reducing it to the sides (a desirable pattern for long-haul truckers). For example, channel"11A" is 27.095MHz, spaced 10kHz after standard channel11 (at 27.085MHz) is used to provide for part of European railroad's Eurobalise radio communication with trains. South Africa, like New Zealand and the UK, permits the use of two HF CB bands. Channel9 is reserved for emergencies, and channel11 is a calling channel. [39] The unofficial "travelers channel" in most of the world is channel19; in Australia it is channel8 (27.055MHz) and UHF channel40 (477.400MHz). Like many other land mobile radio services, multiple radios in a local area share a single frequency channel, but only one can transmit at a time. McCall's "Convoy" and Laurie Lingo & The Dipsticks "Convoy GB" in 1976 (both of which were Top5 hits). [40] Lax enforcement enables manufacturers of illegal linear amplifiers to openly advertise their products; many CB dealers include these amplifiers in their catalogs. The old specification was often used in false advertising by some manufacturers who would claim their CB radios had "5watts" long after the specification had changed to 4watts output. Truck drivers still use CB, which is an effective means of obtaining information about road construction, accidents and police speed traps. Australian CB radio uses AM, USB, and LSB modes (no FM) on 27MHz, allowed output power being 4Watts AM and 12Watts SSB. These services began in 1945 to permit citizens a radio band for personal communication (e.g., radio-controlled model airplanes and family and business communications). Since the price of CB was dropping and VHF Marine Band was still expensive, many boaters installed CB radios. Although licenses may be required, eligibility is generally simple. [12]:12 Channel10 was originally often used for highway travel communications east of the Mississippi River, and channel19 west of the Mississippi; channel19 then became the preferred highway channel in most areas, as it did not have adjacent-channel interference problems with channel9. This agreement provides interference-free operation for all operators by separating the far more powerful SSB stations from the AM stations. These intermediate frequencies are reserved for the Radio Control Radio Service (RCRS).
