The CB Radio Service spectrum is divided into 40 numbered radio frequency channels from 26.965 to 27.405 MHz. Channel spacing is 10 kHz between channel centers with exceptions where CBRS channels are adjacent to Radio Control Radio Service. The initial channel allocations had a gap equal to two channel spaces between channels 22 and 23.
The 27 MHz CB27/81 Bandplan is a list of the channel frequencies for FM CB radio in the United Kingdom.. Unlike CB usage in the United States, and subsequently elsewhere in the world, the original UK 40 channels progress in order with 10 kHz spacing.
These roughly corresponded to the present channels 5–22, except for the two unique frequencies that are known as 11A (Channel 7 on an 18 channel Australian CB) and 19A (Channel 16 on an 18 channel Australian CB) or remote control frequencies but are no longer part of the Australian 27 MHz CB band since 40 Channels were introduced.

20 kHz channel steps, shared with State Forestry in some areas 33.120–33.400 MHz 20 kHz channel steps, some low-power frequencies 35.020–35.980 MHz 20 kHz channel steps, some low-power frequencies 37.440–37.880 MHz 20 kHz channel steps, often used for power and water company communications 42.960–44.600 MHz
Channel 40 is the primary road safety channel Australia-wide, most commonly used by trucks including pilot/escort vehicles for oversized loads. [6] [7] Users should be aware that UHF CB channels 31 to 38 and 71 to 78 are the 'input' channels for repeaters. Users should avoid using these channels to avoid interfering with repeaters.
Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...

Historically, amateur stations have rarely been allowed to operate on frequencies lower than the medium-wave broadcast band, but in recent times, as the historic users of these low frequencies have been vacating the spectrum, limited space has opened up to allow for new amateur radio allocations and special experimental operations.
