11 meter band

[20] After July 1, 1977, the club changed its name to Citizens Band Two Way Communication Club (CBTCC). Japan's CB allocation consists of 8voice and 2radio control channels with a maximum power output of 500mW. Radios There are a few types of CB type radios available to you. 27.125 is another very popular frequency for beacons 27.125 beacon 27.125 MHz beacon. When UHF CB was first legalised the 27MHz CB Band was intended to be closed to Australian CBers in 1982 and only the 477MHz UHF band was to continue, however this did not eventuate. e.g. Commonly there is 'tree' major types of different CB-Radio's Type 1: Uses channels to decide operating frequency. This falls close to the recommended 27.090 MHz to 27.150 MHz bands and the 27.120 MHz, 27.140 MHz, 27.141 MHz and 27.145 MHz frequencies. With the FCC's minimal enforcement of its CB rules, enthusiasts in the US use "export radios" or European frequency modulation (FM) CB gear to escape the crowded AM channels. Channels1014 and 23, after channel9 was reserved for emergency use. In Australia, CB Action Magazine was produced monthly from mid-1977 and continuing publication through until the early 1990s. However, I was listening to a guy on the CB and he said he was a trucker and was using a 10 meter amplifier. A license from ICASA is required to purchase or use a CB radio in South Africa. what are some good models of used ham radios that can be converted to 11 meters and work on AM as well as SSB ? However voluntary donations are welcome, to cover costs for running and maintaining the system. Users on a channel must take turns talking. Feel free to login and start using our website to log your contacts on 27MHz. In the early 2000s, National Communications Magazine added CB radio coverage to its coverage of scanner radios and still remains the only magazine in North America covering CB radio.

During low sunspot activity it may be impossible to use skywave at all, except during periods of Sporadic-E propagation (from late spring through mid-summer). 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. A callbook is a directory of radio station call signs. Many radios sold in South Africa feature both the 27MHz and 29MHz bands. When looking at the FCC/CEPT channel list there are some channels with a spacing of 20kHz instead of the regular 10kHz step. Channel36 (or 38 for LSB) became the unofficial SSB "calling channels" for stations seeking contacts, with the subsequent conversation moving to channels3740. 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. The current specification is simply "4watts output (AM) or 12watts output (SSB)" as measured at the antenna connector on the back of the radio. This page was last modified on 10 April 2023, at 15:35. After modification, you'll have a more powerful CB. This will also improve the ability to "shoot skip" in the 11 meter Citizens Band. The Czech Republic authorizes 80 channels as well (same as the German 80-channel plan). VHF radios are recommended by state agencies, such as Marine Safety Victoria and Marine Rescue NSW. Originally, CB (named Citizens Radio by the Federal Communications Commission as of 1972) required the use of a callsign in addition to a purchased license ($20 in the early 1970s, reduced to $4 on March 1, 1975); however, when the CB craze was at its peak many people ignored the requirement and invented their own nicknames (known as "handles"). Enthusiasts rushed for licences when the doors opened at post offices around Australia in mid-1977 and by the end of the first quarter of 1978 an estimated 200,000licences were issued (Australia's Population in 1978 was 14.36million). [g] While frequencies just below the CB segment (or between the CB segment and the amateur radio 10-meter band) seem quiet and under-utilized, they are allocated to other radio services (including government agencies) and unauthorized operation on them is illegal. New Zealand and Japan have unique allocations compared to any other country. The European Conference of Postal and Telecommunications Administrations (CEPT) adopted the North American channel assignments, except channel23, frequency 27.235MHz; channel24, frequency 27.245MHz; and channel25, frequency 27.255MHz. The other problem with shortrange CB use is propagation; during longrange "skip" conditions local signals are inaudible due to reception of multiple distant signals. Yet another logging software for 11 meters band. Under this class assignment, a CB radio is classified as a "Personal Radio Service device". Unlike amateur radios with continuous frequency tuning, CBs manufactured for export are channelized. Furthermore, illegal transmitters and amplifiers may not meet good engineering practice for harmonic distortion or "splatter", which may disrupt other communications and make the unapproved equipment obvious to regulators. Over the next several years antenna regulations were relaxed, with antenna length increasing to 1.65meters (5'5") and centre- or top-loading of the main radiating element permitted.

Paging is permitted on channel1 (26.965MHz) and channel80 (26.955MHz) is the recommended call channel for Czech CB radio operators. It is also illegal to use these radios outside of the Amateur Radio bands by anyone in the US, since they are not type-certified for other radio services and usually exceed authorized power limits. These intermediate frequencies are reserved for the Radio Control Radio Service (RCRS). [21], Source:[22] American CB licensees were initially required to apply for a temporary license to operate in Canada. Single-sideband (SSB) operation involves the selection of either the Lower Side Band (LSB) or the Upper Side Band (USB) mode for transmit and receive. Geographical power restrictions apply to the 630 meter, 70 centimeter, 33 centimeter and 23 centimeter bands. The prominence of CB radio grew in Britain partly due to the success of novelty songs like C.W. The 27MHz frequencies used by CB, which require a relatively long aerial and tend to propagate poorly indoors, discourage the use of handheld radios. They do not require a ground plane to present a near-50ohm load to the radio, and are often used on fiberglass vehicles such as snowmobiles or boats. 27, 27.285 MHz AM - CB channel 28 - AM DX calling channel, see also: 27.025 MHz, etc, 27.315 MHz AM - CB channel 31 - AM DX calling channel (secondary), 27.315 MHz FM - European FM calling channel, 27.355 MHz LSB - CB channel 35 - SSB DX calling channel Australia and Oceania, 27.368 MHz USB - Militia Patriot SSB CB 11m tactical - USB mode 27.368 USB, 27.378 MHz USB - Militia Patriot SSB CB 11m tactical - USB mode 27.378 USB, 27.385 MHz LSB - CB channel 38 - SSB DX calling channel, LSB mode - North American SSB channel (see also: 27.375 LSB, 27.395 LSB).

Some links may be affiliate links. The old MPT1320 27/81 band will continue to be available for the foreseeable future. Marketing, import and sale of such radios is illegal if they are distributed as anything other than Amateur Radio transceivers. It is an unofficial practice to name these channels by their next lower standard channel number along with a suffix"A" (after). With the original 23CB channels SSB stations commonly used channel16, to avoid interference to those using AM (SSB stations are authorized to use 12watts, as opposed to 4watts for AM stations) and to more easily locate other SSB stations. [28], In Malaysia, citizens band radios became legal when the "Notification of Issuance Of Class Assignments" by Communication and Multimedia Malaysia was published on 1April 2000. Individual licensing came to an end on April 28, 1983.[9]. SSB radios also have the standard AM mode for communicating with standard CB radio models. 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. Operation on frequencies above or below the citizens band (on the "uppers" or "lowers") is called "freebanding" or "outbanding". Far as ground plan antennas the best I have ever used is a 5/8 called a shockwave built in alabama. S9s successor was Popular Communications, which had the same editor under a different publisher beginning in 1982. The business band requires an FCC license, and usually results in an assignment to a single frequency. [34], The standard channel numbering is harmonized through the FCC (America) and the CEPT (Europe).[d][35]. New Zealand has adopted the Australian UHF CB System as well.[37]. Older amateur radios may require component changes; for instance, the 1970s Yaesu FT-101 was modified for CB by replacing a set of crystals used to tune portions of the 10meter band, although some variants of the FT-101 were sold with the US FCC channels standard and were capable of transmitting above and below the legal 40channels by another 10or more channels. RCRS was formerly known as the Class C Citizens Radio Service until the 1976 changes. In the United States, it is no longer illegal to engage in (or attempt to engage in) CB communications with any station more than 250km (160mi) from an operator's location. re-assigned on September 11, 1958 for CB use effective October 1, 2024 to promote an all digital transmission band. 26.955 MHz AM - Channel 40 down one band, popular in USA for local radio nets, 27.025 MHz AM - CB channel 6 - The Superbowl -, 27.085 MHz AM - CB channel 11 - AM DX calling channel - the original calling channel from the 23 channel CB days, 27.125 MHz AM - CB channel 14 - often used as a local AM CB channel, also used for AM CB in Europe and UK, 27.135 MHz AM - Russian Trucker channel (see also 27.135 MHz FM, 27.180 MHz), 27.143 MHz CW - 14RS000 11 meter beacon CB beacon 27145 LSB 27140 USB 27.140 MHz USB 27.14245 MHz, 27.145 MHz LSB - 14RS000 beacon 11m beacon 11 meter beacon 27 MHz CW beacon 27.143 MHz, 27.165 MHz AM - CB channel 17 - often used as an alternate channel to 27.185/channel 19 for truckers, 27.185 MHz AM - CB channel 19 - trucker channel, road channel, interstate highways, probably the best spot to try first, 27.215 MHz AM - CB channel 21 - often used as an alternate channel to 27.185/channel 19 for truckers, 27.235 MHz FM - European packet PSK31 channel - channel 24, 27.235 MHz USB - Swedish and Nordic SSB calling Sweden, 27.235 MHz USB - European digital modes ROS data modes channel, 27.245 MHz FM - European packet PSK31 channel, 27.245 MHz USB - European digital modes ROS data modes channel, 27.255 MHz USB - WSPR weak signal digital modes 11m frequency (confirmed active July 2021), 27.255 MHz CW - 11 meter beacon 27 MHz beacon CB, 27.265 MHz AM - CB channel 26 - AM DX calling channel, see also: 27.025 AM, 27.085 AM, 27.285 AM, 27.275 MHz USB - UK SSB calling England mid band SSB frequency ch. However, in November 1981 (after high-profile public demonstrations) 40frequencies unique to the UK, known as the 27/81 Bandplan using FM were allocated at 27MHz plus 20channels on 934MHz (934.0125934.9625MHz with 50kHz spacing). The original channels1, 2, 3, 4, 10, 21 and 23 were deleted from the 18channel band plan. In the United States, the FCC bans the importation and marketing of radios it deems easily modifiable for CB;[46] it is illegal to transmit on CB frequencies with a ham radio except in emergencies where no other method of communication is available. Text is available under the Creative Commons Attribution-ShareAlike License 3. . To Optimize for 11 meter performance assemble the antenna with the 12" optimizer section installed between the mid and top section as a 4 piece antenna. Majority of countries require no license to operate the radio service. Two magazines that dominated the time period were S9 CB Radio and CB Radio Magazine. [41] Walkie-talkie hand-held units became affordable with the use of transistors. This agreement provides interference-free operation for all operators by separating the far more powerful SSB stations from the AM stations. Unlike the 10 Meter Band, access to these frequencies are unrestricted by the FCC, hence the name "Citizen's Band". Kanava-taajuustaulukko-10-ja-11-metrin-radioille.pdf. To achieve this effect, the antennas must be separated by about eight feet, only practical on large trucks. During the 1960s, the service was used by small businesses (e.g., electricians, plumbers, carpenters), truck drivers and radio hobbyists. This is roughly 9feet (2.7m) tall; it is mounted low on the vehicle body, and often has a spring-and-ball mount to enhance its flexibility when scraping or striking overhead objects. If the first letter is not specified, it is considered that it is (C). Australia also permits the use of marine VHF radio. In some instances, the sale or ownership of foreign-specification CB gear is not illegal but its use is. 11DX.net is free to use. For these bands, the gain is lowered so that the antenna covers a larger bandwidth. Callbooks have evolved to include online databases that are accessible via the Internet to instantly obtain the address of another amateur radio operator and their QSL managers. On 1September 1987 the UK added the usual 40frequencies (26.96527.405MHz) used worldwide, for a total of 80channels at 27MHz; antenna regulations were further relaxed, and the 934MHz band was withdrawn in 1998. In radios with more then 40 channels they are divided into 'bands' consisting of 40-80 channels. for RadioShack stores in the mid-1990s. 11 meter band plans freeband CB channels frequencies survivalist emergency CB bands CB channels on ham radio frequency mod channel expansion 27 MHz 11 meter band "Free band" or "freeband" refers to the frequencies both above and below the legal CB band. Some countries also have personal radio services in the UHF band, such as the European PMR446 and the Australian UHF CB. They typically have a knob and display that reads up to channel40, but include an extra band selector that shifts all 40channels above or below the band and a "+10kHz" button to reach the model control "A"channels. - The HB9CV Ready for 'The BIG Test Run'. Frequency seems they have much much better ears/rx than cb's/export . Handheld CBs may use either a telescoping center-loaded whip or a continuously-loaded "rubber ducky" antenna. Sometimes less than 10channels are designated 2digits. Amateur Radio Service operators record, locate, and report to the FCC frequency trespassing and intrusions of their frequency allocations by pirate transmissions or illegal operators for enforcement action.[45]. The callsign with which you registered. South Africa, like New Zealand and the UK, permits the use of two HF CB bands. The rules regarding non-approved radios and power levels above 4Watts on AM/FM and 12Watts on SSB still apply, despite deregulation. The maximum legal CB power output level in the U.S. is 4watts for AM (un-modulated carrier; modulation can be four times the carrier power, or 16watts PEP) and 12watts for SSB, as measured at the transmitter antenna connection. The recent FCC decision to open the 11-meter band to Class D Citizens Band operation makes it possible for anyone (except those under 18 and aliens) to own and operate a short-wave transmitting and receiving station. The maximum power allowable on the MPT1320 27/81 system was 4watts (in common with the American system), although initially radios were equipped to reduce output power by 10dB (to 0.4watts) if the antenna was mounted more than 7meters (23') above ground level. However, external linear amplifiers are often used illegally. Amateur Radio Service was an egregious act," said a spokesperson. The phenomenon also inspired several popular and country music songs in 1975 and 1976: Betty Ford, the former First Lady of the United States, used the CB handle "First Mama".[11]. Used mostly by truckers and some off road clubs (4WD) Not extremely reliable, gets pretty crowded on the channels and the language on there can be pretty offensive at times. [citation needed]. ClassB radios had simpler technical requirements, and were limited to a smaller frequency range. 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. After this date, use of unregistered 23channel CB sets was deemed illegal and unlicensed sets were no longer eligible to be licensed.

Legal operation in one country may be illegal in another; for example, in the UK until June2014 only 80FM channels were legal. 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 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. I have own Antron 99 imax2000 Maco v5000 . LF11 Cluster available on Androidby Greg at 2019-02-07 Novice and Technician licensees outside ITU Region 2 may use CW only between 7.025 and 7.075 MHz and between 7.100 and 7.125 MHz. Here we have collected some links to building instructions for 11m antennas on the Internet. [15][16] By the mid-1970s, hobbyists were experimenting with handheld radios and unauthorized 23channel American CB radios. Legal (shortrange) use of CB radio is sometimes impeded by users of illegal highpower transmitters, which can be heard hundreds of miles away. For example, (C9EF, 9EF), hereinafter ("9") the channel number. These frequencies may have evolved because tuned circuits (particularly antennas) work best in the middle of the band; the frequency for channel19 (not channel20) is the center of the 40channel US band and other things being equal, signals will be transmitted and heard the farthest. During the 1970s and 1980s peak years of CB radio, many citizens band-themed magazines appeared on newsstands. 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. An unofficial citizens band radio club in Malaysia is the "Malaysia Boleh Citizen Radio Group", known as "Mike Bravo" (Malaysia Boleh).[32]. A gray market trade in imported CB gear exists in many countries. During the 1970s, the FCC banned the sale of linear amplifiers capable of operation from 24 to 35MHz to discourage their use on the CB band, although the use of highpower amplifiers continued. The FCC restricts channel9 to emergency communications and roadside assistance. (1977), Citizens Band (a.k.a. Whereas, the bands on the right (11, 15, and 20 Meters) are much narrower (<3% at the design frequency) and can realize a higher gain and still cover the whole band with an SWR <= 1.75:1. Until 1975,[12]:14 only channels914 and 23[a] could be used for "interstation" calls (to other licensees). [8] The radios were crucial for independent truckers; many were paid by the mile, and the 55mph speed limit lowered their productivity. Channel9 is reserved for emergencies, and channel11 for calling. In Brazil, CB channels were upgraded from 23 to 60 channels starting in 1979 and again in 1980 to 80 channels[pt] (from 26.965MHz to 27.855MHz). [citation needed] Reality is far different: Attempting an SSB conversation while an AM conversation is in progress results in jammed communications for everyone. Voice actor Mel Blanc was also an active CB operator, often using "Bugs" or "Daffy" as his handle and talking on the air in the Los Angeles area in one of his many voice characters. Similar to Internet chat rooms a quarter-century later, CB allowed people to get to know one another in a quasi-anonymous manner. Recommended beacon frequencies for 11 meter band - +/- 5 kHz or sofor example, 27.140 MHz / 27140 has two active beacons nearby on 27.1408 MHz 27140.8 kHz and 27.1416 MHz 27141.6 MHz.
