Simplified equipment guide

This is a simplified guide of what equipment can be used on CB in the UK, this focuses on radios, not antennas

Legal equipment

This is a list of how to identify legal CB equipment

On the radio itself

  1. A circle containing the wording "CB 27/81", these will also say somewhere "manufactured to Home Office standard MPT 1320", usually on the rear
  2. A rectangle containing the wording "PR 27/97" followed by a second one that reads "For use in the UK only"
  3. A rectangle containing the wording "PR 27/94"
  4. A rectangle containing the words "CEPT PR 27 GB" or "PR 27 GB", these would be 40 EU channels only and in FM, under the proposals these would not be able to be used in a vehicle as the CB that must be installed as they lack the UK40 channels, however they can still be installed if an older 27/81 set is already installed in the vehicle
  5. The "CE" mark and, where applicable, a 4 digit number on the rear panel along with an exclamation mark in a circle, the equipment will have something called a "declaration of conformity" in its manual, usually at the rear

in advertisements the radio would be described as FM, 4 watts or multistandard, 40 or 80 channels, all radio businesses sell legal radios, on eBay you can find older American imports which you cannot use legally in this country, the only people that could legally use these are licenced Amateur radio operators for conversion to the 10-meter band.

non-legal equipment

  1. Radios described as "export" radios, these are mainly 10-meter radios and do not meet the requirements to be used on CB, as such they would fail inspection under the proposed regulations
  2. Linear amplifiers
  3. These are not allowed on CB under any circumstances, and if found during inspection under the proposed regulations this would cause a failure of the inspection, these bring the transmit power of the radio up above 4 watts, unfortunately they have an unwanted side effect of causing interference to other radio services including those used in safety-critical situations
  4. Any equipment that has been modified outside type approval, this may not be spotted immediately however modified radios are either modified to go out of band to other channels that are not legal anywhere or increase of transmit power which will likely be poorly done and cause interference to other services like the linear amplifiers can, modification to the radio could potentially result in a fail of the inspection proposed under the proposed regulations
