89:, experimentation with different types of apparatus, and modes of modulation is not permitted, and equipment must be factory-built and approved. Many of these services require non-removable antennas or place restrictions on antenna size, height or gain. The high-VHF band (137–174 MHz) and UHF bands (325, 900 MHz) are the most popular aside from the 25–28 MHz "HF CB" bands. There are notable exceptions to this, including the 78 MHz and 245 MHz Thai "CB 78" and "CB 245" VHF-FM bands, the 68–71 MHz Finnish band, the 30–31 MHz Swedish "Hunting Radio" band, and the 43 MHz Italian "VHF CB" bands. The lower frequency allocations (especially the 30/31 and 43 MHz bands) often exhibit propagation and communication range characteristics similar to 27 MHz CB radio. Higher frequencies (especially above 200 MHz) are almost exclusively line-of-sight.
1061:"VHF CB" allocation at 43 MHz, usually called "Apparati a 43 MHz" or "CB 43 MHz". Italy, like many other countries, suffers from extremely lax enforcement of radio communications laws, and "freeband" modified equipment covering wider frequency ranges as well as amplifiers are widely available and openly advertised by communications equipment vendors. "Freebanding" occurs with both the 27 MHz area (often as low as 25 MHz and as high as 30 MHz) and the 43 MHz area (as 43 MHz CB equipment is often modified to cover down to 34 MHz and up to 47 MHz, using 12.5 kHz steps). There is evidence of these frequencies being used outside of Italy for illegal "CB-like" operations.
2265:
27.415–27.855 MHz make up the first set. These are referred to as the "European channels" or the "fives" due to the frequency ending in 5. The second set, known as the "Polish channels" or the "zeros" is 26.510 – 26.950 MHz, 26.960–27.400 MHz and 27.410–27.850 MHz. 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). It is important to note that only 26.515–27.855 / 26.510–27.850 MHz is legally permitted in Russia.
101:; a user must wait for the shared frequency to be clear before transmitting, and all stations on the frequency may hear the transmission. Since both stations are on the same frequency, the receiving station cannot interrupt the transmitter until it has finished. Generally only voice transmission is allowed under personal radio service regulations, although tone and digital selective calling features are allowed in some countries. Some services permit digital data transmission, either as part of digital "text messaging" and GPS location "sharing" with other nearby radios (such as FRS), or the services themselves involve digital voice and data transmissions (such as DPMR446/DMR446).

Internet gateways, simulcasting via several repeaters at once, and cross-band repeat connections to the UHF PMR446 service. Cities such as Moscow and St. Petersburg feature motorist emergency services that are directly accessible via a CB frequency monitored by police and other emergency services. Other services provided by cities in Russia include weather broadcasts and travel/traffic information and warnings via specific CB channels.

However, store-and-forward digital operations are not permitted and transmitters must not operate in continuous-carrier (constant transmit) mode. External antennas are permitted, transmitter output power is limited to 2 watts. MURS is often used for data transmissions as well as portable and mobile voice communications, due to the external high-gain antenna provision, MURS offers the possibility of greater range than FRS. As with CB, FRS and GMRS, there are reports of users using higher-than-legal power levels on the MURS frequencies.

The B-C-D (or "grid") designation comes from common export radio band labeling. Originally these radios would feature 5 bands labeled A-B-C-D-E, with coverage from 26.065 to 28.305 MHz, later these radios switched to a 6 band configuration A-B-D-C-E-F with coverage from 25.615 to 28.305 MHz, making 26.965–27.405 MHz band D instead of band C.
2244:) Like many rules regarding the HF CB services, the distance prohibition is largely ignored and unenforced. Often as a result of channel overcrowding and interference, many HF CB users have turned to purchasing "export" or "10-meter" radios that operate in the legal CB band but also provide access to frequencies above and below the CB 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). This has created a
