Car radios have long been associated with truckers, but ordinary drivers are increasingly using them, especially on long trips on two-lane highways. They are not very effective in urban environments, but on the highway they allow you to quickly receive information about the traffic situation, traffic jams, cameras, patrols and cafes along the way. A radio is especially useful in remote regions with poor GSM coverage, as well as when traveling in a convoy, when quick communication between cars is needed.
Off-road training expert Sergey Saiman notes that a radio station helps to improve traffic safety: you can negotiate with truckers about a "window" for overtaking. However, communication requires knowledge of driver jargon, and advertising and profanity are found on the air. The radio does not replace the navigator, but for joint trips with friends it can become an indispensable tool.
The choice of radio begins with an understanding of the law. Civil band devices are suitable for car travel, which can be used without licenses. The most popular are CB radios (27 MHz, up to 5 W), used by truck drivers. VHF radios (400 MHz), which require a ham radio license, are less in demand. There are also low-power PMR/LPD devices such as Walkie Talkie for traveling in several cars, their use is simple and safe.
The radio consists of a station and an antenna. Antennas are available in mortise and magnetic base: the former are installed reliably, but spoil the body, the latter are easy to dismantle, but can fly off at high speed. The optimal antenna length is 1–1.2 meters. Most motorists use the 15th channel (27.135 MHz) with amplitude modulation, so it is important that the device operates in the range of 26.945–27.405 MHz.
When buying, take into account the power, modulation, noise reduction, power supply and the availability of quick switches to popular channels. For the highway, a power of 2–10 W and a power supply from the 12 V on-board network is sufficient. Automatic noise reduction makes the conversation more comfortable, and built-in buttons and a screen simplify operation.
Budget models are available on the market from 4,000 rubles, but without a screen and with low power. More advanced options cost from 13,000 rubles and are equipped with a large screen, automatic noise reduction, channel search functions and quick switching.
Among the features of the choice, the antenna mount, ease of operation and compatibility with popular trucker channels are also important. A convenient handset with a transmit button makes it easier to work while driving and increases driver safety.
Thus, a radio is not a luxury, but a practical tool for long trips, especially where mobile communications are unstable. It allows you to stay in touch with colleagues, receive up-to-date information and improves the organization of traffic during joint trips.
