Norway has a Short distance radio service (called "KDR444" to distinguish it from similar services such as PMR446) with six UHF FM channels between 444.600 and 444.975 MHz. External high-gain antennas are permitted. Use of selective calling and tone squelch systems such as DTMF, CTCSS and DCS are allowed. Thailand has two 80 channel CB-style services, one in mid-band VHF 78 MHz band and another at high-band VHF 245 MHz band. The 4-Wheel Drive Club of South Africa (4WDC) uses their own internal channel numbering scheme for these frequencies. When first developed in the United States, CB operation required an individual license fee. EA Networks, New Zealand. For example, 27.185 MHz AM (Channel 19 in the European/American frequency plan) would be designated "C19EA" or "C19EAM". Multi-norm radios sold in Europe and Asia designed for use in several different countries – with the end-user selecting the "mode" of the country they live in – now come with a "RU" (Russia) mode that opens the radio to full band coverage (usually 25.615–28.305 MHz or 25.615–30.105 MHz). Brazil allows higher power levels than the US and most of Europe. Handheld radios are available for these frequencies, with some models including both the 30/31 MHz band and the 155 MHz band.[13]. Blogs, RSS, Youtube channels, Podcast, Magazines, etc. Because both Norway and Sweden have high-band VHF FM hunting allocations (see section on Sweden below), many hunting radios are marketed with both the 6 Norse channels and 7 Swedish channels in one unit. SCIS no. Similar to Norway, Sweden also has Jaktradio (Hunting Radio) allocations, 6 channels in the 155.400–155.525 MHz band and 40 channels in the 30–31 MHz band. Other CB users purchase amplifiers to increase their output power and "punch through" interference caused by distant stations (or by local stations running amplifiers). 12.5 kHz channel spacing with skips. Protests against the South African rugby team touring New Zealand divided the country in 1981. In urban areas, simplex repeaters, usually mounted on the roofs of high-rise buildings, are used to increase communication range. Units are allowed up to 10 watts PEP RF power. There are two HF AM/SSB CB bands available for use in South Africa, 27 MHz and 29 MHz.

Citizens Band radio is a family of services available in different countries and with different operating rules, generally using channels in the 27 MHz part of the radio spectrum. There are an estimated one million users of the 245 MHz VHF CB service, often in large cities.[14]. In addition to the UHF FRS and GMRS allocation and the high-HF CB allocation, in 2000, the American FCC allocated five VHF channels to the Multi-Use Radio Service (MURS). As these walkie-talkies are low-powered devices which do not potentially cause interference to other licensed radio services, it need not be licensed for use in Singapore. "To ensure the success of the forthcoming quarantine-free green zone between New Zealand and Australia, more preventive interventions are needed to reduce the frequency of such failures. Radios must be equipped with a GPS and built-in control ROM for automatic digital callsign identification. Germany only allows FM on channels 41–80. 43.5875 MHz – For use by health professionals, doctors, hospitals, and activities related to them. FM may be used throughout Europe on the standard 40 channels – called the "mid band" or "CEPT" channels. 142 & 146 MHz VHF-Digital "Personal Radio" service for Personal, Leisure and Family use. As more users purchase amplifiers and operate on out-of-band frequencies, more interference is produced, forcing others to acquire even more powerful equipment to punch through even more interference, and/or to acquire transceivers capable of accessing more frequencies so that a clear frequency may be found. Like CB, MURS frequencies may be used for business or personal/family communications. EA Networks is a locally owned co-operative network company based in the Mid Canterbury region of New Zealand’s South Island. 43.5750 MHz – For use by health professionals, doctors, hospitals, and activities related to them.
