Page "CB radio in the United Kingdom" Paragraph 13

The UK channels that were legalised on 2 November 1981 were on two blocks of frequencies: 40 channels on the 27 MHz band and 20 channels on the 934 MHz band, both of which used FM ( frequency modulation ) and both unique to the UK.

The 27 MHz band frequency allocation is shown here: 27 MHz CB27 / 81 Bandplan.

In 1987 40 additional frequencies were added, which were ironically the same as the U. S. allocation-but again using FM.

This additional band is often referred to as the CEPT or EU band.

As with the ' old ' channels, this band suffered from increased ' skip ' reception, especially towards the maxima of the 11-year sunspot cycle.
