Small F.A.Q.

Table 1.
Standard “European” grid of 40 channels

Notes and explanations:

1. In most countries, a frequency plan for the civil band of 27 MHz (CB, “Citizens Band”) has been approved, containing 40 standard channels with numbers from 1 to 40 (harmonized by the FCC (America) and CEPT (Europe)).

2. In addition, within the range, 5 “hidden” channels are allocated for radio control, modeling and data transmission devices (these channels are indicated by R/C and are highlighted in light-blue). Channel 23 was also previously intended for radio control, but now it is also used for voice communications.

3. Channel 9 with a frequency of 27.065 MHz (highlighted in red) is an emergency channel and is usually tapped by government rescue services.

4. Channel 19 is considered the common channel of the call (after establishing communication on this channel, the interlocutors usually switch to another channel for communication). In addition, in a number of countries, this channel is considered the channel of truckers and travelers. However, in some countries truck drivers often use other channels, for example: 5 AM in Italy, 13 AM in Greece, 15 in Russia. These channels are highlighted in yellow.

5. Channels 23, 24, 25 have frequencies out of order, because the very first standard of the radio for free using by civilians (USA, 1958) had only 23 channels.

6. Some countries (e.g. Poland, Kazakhstan and Russia (officially)) use a frequency grid with frequencies reduced by 5 kHz. Thus, there the frequency of channel 19, for example, will be 27.180 MHz. In some multi-standard radios (for example, Luiton LT-298), the frequency shift is carried out by selecting the country code (PL), and in some – by pressing a special button.

7. In some countries, not the only standard, but additional frequency bands are allowed. Most often, they are switched by changing the channel letter (BAND). The correspondence of the frequencies of the channels in such cases is indicated in the second table (see below). In this case, most often as the main (central) band is Band D, the channels of which correspond to the standard grid of 40 channels. In walkie-talkies of different manufacturers, letters may differ (see the names in the right column).
