ETSI TR 102 626 V1.1.1 (2009

08)

6 Current regulations

There is ERC/DEC(98)11 [i.2] in place for angle modulated CB radio equipment.

The following information is the list of CB radio country regulation as in November 2008:

• Implementation of ERC/DEC(98)11 [i.2] is in all EU countries, in addition in 4 other EFTA countries (IS, N,

CH, FL) - single mode, FM only with up to 4 Watts output power. However, the situation is far from being

harmonized:

- Austria allows only single mode FM- modulated CB radios without switch to other modes that can be

operated by a user.

- Some countries allow additional channels(e.g. D, CZ, SK and UK).

- Some countries allow AM- modulation:

AM with 1 Watt: B, BG, CH, D, E, EST, F, FIN, FL, GR, I, IRL, LV, NL, P, PL, RO, RSM.

AM with 4 Watts: E and PL, whereas Poland has a 5 kHz channel centre frequency offset.

AM with 5 Watts: I, however just for 34 channels.

- Some countries allow SSB- modulation:

SSB with 40 channels with 4 Watts PEP: B, CH, D, FL, F, FIN, GR, I, LV, NL, P, RSM.

SSB with 40 channels with 12 Watts PEP: E and PL.

The investigation also triggered unclear responses with regard to the use of AM- and SSB- modulation in some other

countries. Another investigation performed by ECC/WGFM/SRDMG on T/R 20-09 [i.1] also showed "no information"

for 17 countries.

The number of SSB countries is less than the number of AM countries, because not all countries answered the request.

Where no answer was received, they have not been placed on the SSB list.

7 Proposed regulations

A harmonized usage of CB radio in Europe with the following parameters is proposed to be investigated:

• Harmonized use of FM/AM modulation and SSB throughout Europe based on EN 300 135 [i.3] and

EN 300 433 [i.4] with output power levels of up to 4 Watts AM/FM - modulation and 12 Watts PEP for SSB

using the spectrum identified by ERC/DEC(98)11 [i.2].

8 Main conclusions and justification

At present the plethora of different National regulation both confuses users and hinders sales. Given that long distance

lorry drivers may transit a large number of European borders in the course of a few days consideration should be given

to harmonizing both the technical regulation and the licensing position of this much travelled equipment.

Harmonization of the technical parameters will provide a new impetus to sales and driver safety.

Citizens' Band equipment has been on the European market since the early 1970,s whilst it has always had to conform

to the stringent spurious levels required for broadcast bands, its early use was predominately in domestic premises

where it caused interference to broadcast band 1 television receivers. Since that date:

• Europe agreed: The Chester 1997 Multilateral Coordination Agreement relating to Technical Criteria,

Coordination Principles and Procedures for the introduction of Terrestrial Digital Video Broadcasting

(DVB-T).
