scope:

This European Telecommunications Standard (ETS) applies to Double Side Band (DSB) and/or Single Side Band (SSB) amplitude modulated Citizen's Band (CB) radio equipment operating in the frequency band 26,960 MHz to 27,410 MHz with a channel spacing of 10 kHz, and intended for analogue speech and/or data transmission.

This ETS covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable.

This ETS covers base stations, mobile stations and two categories of hand-portable stations.

This ETS is complementary to ETS 300 135 [1] which concerns angle modulated CB radio equipment (CEPT PR 27).

Any CB equipment covered by this ETS that can also work with angle modulation is also required to meet ETS 300 135 [1].

This ETS is based upon existing national standards.

This ETS applies to equipment with a socket for an external antenna and to equipment with an integral antenna.

In the case of equipment that is intended for use with either an integral antenna or an external antenna, the equipment is specified to be measured as equipment intended for use with an external antenna and specified to meet the appropriate limits. In addition to this the following characteristics of the transmitter and receiver are specified to be measured as for equipment for use with an integral antenna and the appropriate limits are defined:

- transmitter carrier power;

- spurious emissions of the transmitter;

- spurious radiation of the receiver.
