1 Scope
The present document covers the technical requirements for transmitters and receivers used in stations of angle
modulated, Double Side Band (DSB) modulated and/or Single Side Band (SSB) modulated Citizens' Band (CB) radio
equipment operating in all or part of 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.
Citizens' Band radio equipment operation is in accordance with Draft ECC Decision on the harmonised use of
frequencies for Citizens' Band (CB) radio equipment [i.2].
The equipment operates on one or more channels of the carrier frequencies as shown in table 1.
Table 1: Carrier frequencies
Carrier Channel Carrier frequencies Channel
frequencies Number Number
26,965 MHz 1 27,215 MHz 21
26,975 MHz 2 27,225 MHz 22
26,985 MHz 3 27,235 MHz 24
27,005 MHz 4 27,245 MHz 25
27,015 MHz 5 27,255 MHz 23
27,025 MHz 6 27,265 MHz 26
27,035 MHz 7 27,275 MHz 27
27,055 MHz 8 27,285 MHz 28
27,065 MHz 9 27,295 MHz 29
27,075 MHz 10 27,305 MHz 30
27,085 MHz 11 27,315 MHz 31
27,105 MHz 12 27,325 MHz 32
27,115 MHz 13 27,335 MHz 33
27,125 MHz 14 27,345 MHz 34
27,135 MHz 15 27,355 MHz 35
27,155 MHz 16 27,365 MHz 36
27,165 MHz 17 27,375 MHz 37
27,175 MHz 18 27,385 MHz 38
27,185 MHz 19 27,395 MHz 39
27,205 MHz 20 27,405 MHz 40

Transmission and reception takes place on the same channel (single frequency simplex mode).
Any equipment using national regulations on Citizens' Band (CB) permitting the use of channels outside of the carrier
frequencies shown in table 1 within the frequency range from 26 MHz to 28 MHz can use the present document.
The types of equipment covered by the present document are as follows:
- Base station: equipment fitted with antenna connector.
- Mobile station: equipment fitted with antenna connector.
- Hand portable stations:
a) either fitted with an antenna connector; or
b) without an external antenna connector but fitted with a permanent internal or a temporary internal 50 Ω
RF connector which allows access to the transmitter output and the receiver input.
Hand portable station equipment without an external or internal Radio Frequency (RF) connector and without the possibility
of having a temporary internal 50 Ω RF connector is not covered by the present document.
