Does it need a license?
No, one does not need to apply for a license and no license fees is payable for that. The operation of CB radio is authorized under the Radio communications (Citizen Band Radio Stations) Class License 2002. This one is the ACMA website.
CB voice communication became extremely popular in the year 1970. It is extremely popular in cars and trucks till date. This portable communication is carried by using hand held transceivers which most of the CBers operate from home.
CB band comprise 40 channels in which narrow band 27 MHz is the most popular one. All of these 40 channels are overcrowded. The 27 MHz band supports worldwide communication which is known as “skip”. The 11-year sun spot cycle witnessed congestion at its worst during peaks.
Freebanding or bootlegging
The Federal Communications Commission’s (FCC) allows people to cover a fix frequency range. Despite all prohibitions, a few CB operators obtain illegal devices to transmit higher output power and frequency coverage greater than allowed. They do so in order to communicate over long distances or to compete with the other users of the trade. This is what we call bootlegging.
