ETSI EN 300 135-1.

Electromagnetic compatibility and Radio spectrum Matters (ERM)
Angle-modulated Citizens Band radio equipment
(CEPT PR 27 Radio Equipment);

Part 1: Technical characteristics and methods of measurement

1 Scope

The present document 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 which may be required by a user, nor does it necessarily represent the optimum performance achievable. It applies to angle modulated Citizens' Band radio equipment (CEPT PR 27) operation in the frequency band 26,960 MHz to 27,410 MHz with channel separations of 10 kHz, and intended for analogue speech. The present document applies to equipment with a socket for an external antenna and to equipment with an integral antenna.

ETSI EN 300 433-1.

Electromagnetic compatibility and Radio spectrum Matters (ERM);
Land Mobile Service;
Double Side Band (DSB) and/or Single Side Band (SSB)
amplitude modulated citizen's band radio equipment;

1 Scope

The present document applies to Double Side Band (DSB) and/or Single Side Band (SSB) amplitude modulated Citizens' Band (CB) radio equipment using the available bandwidth, operating on radio frequencies within the 27 MHz CB band, with channel separation of 10 kHz, intended for voice and data transmissions. It applies to analogue and combined analogue and digital radio equipment with an internal or external antenna connector intended for the transmission of data and/or speech.

Draft ETSI EN 301 489-13

ElectroMagnetic compatibility and Radio spectrum Matters (ERM);
ElectroMagnetic Compatibility (EMC) standard for radio
equipment and services;

Part 13: Specific conditions for Citizens' Band (CB) radio
and ancillary equipment (speech and non-speech)

1 Scope

The present document, together with EN 301 489-1 [1], covers the assessment of Citizens' Band (CB) radio equipment, intended for the transmission of speech and/or data (non-speech), and associated ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC).

Technical specifications related to the antenna port and emissions from the enclosure port of CB radio equipment are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum.

The present document specifies the applicable EMC tests, the test methods, the limits and the performance criteria for CB radio equipment (speech and/or non-speech), and associated ancillary equipment.

Definitions of types of CB radio equipment covered by the present document are given in annex A. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN 301 489-1 [1], the provisions of the present document take precedence.

The environmental classification and the emission and immunity requirements used in the present document are as stated in EN 301 489-1 [1], except for any special conditions included in the present document.

ETSI TR 101 837.

Electromagnetic compatibility and Radio spectrum Matters (ERM); Study on 27 MHz CB radio compatibility with analogue television broadcast receiver installations.

1 Scope

The present document presents the study on CB 27 MHz radio compatibility with analogue television broadcast receiver installations.

In order to avoid the near field measurement at 27 MHz using reference antennas intended for 50 MHz and more (because the radiated field measurements below 30 MHz are not normally specified) an appropriate 27 MHz dipole antenna has been calibrated to use when necessary.

The study has been carried taking into consideration the field strength level of 125 dB?V/m as the general limit of immunity to ambient electromagnetic fields at the antennas of TV and FM radio reception installations (CISPR 20 [2],clause 4.1.1).

The present document has two main parts: The study of different each elements of a TV-FM broadcasting installation (clause 5) and the behaviour of the TV installation as a whole (clause 6) when it is illuminated by an electromagnetic field of 27 MHz from a neighbouring site.
