Category: Free band

Freebanding generally means operating on frequencies above or below the legal CB band in your country. What may be a legal CB frequency in one country may not be legal in another. For example, a trucker operating on CB channel 19 wishes to find a clear frequency to talk to another driver without all the interference found on 27.185 MHz. So he (and the person he’s talking to) switch their radios “down one band” (-450 kHz or -0.450 MHz) from 27.185 MHz to 26.735 MHz. The radio’s channel display still says “19” but the bandswitch has been moved down one. Often export radios will have 3, 6, 8 or even 12 bands. Freebanding does have some general “gentlemen’s agreements” in place. For example, AM operators usually stick to the lower frequencies below CB channel 1 (26.965 MHz), with activity cantered around 26.915 MHz (channel 36 down one band), 26.885 MHz, (channel 33 down one band) and other frequencies relatively close to the legal CB band. There are practical reasons for this, the primary one being antenna performance decreases the further away one gets in frequency from the antenna’s resonant frequency.
