A CB radio frequency chart usually shows a station’s frequency on certain designated channels. CB radio is otherwise known as CDSL or Continuous Channel Service. Freebanding is when an owner uses other channels in the 11.2 meter band beyond the allowed frequency range. Most of the other frequencies in the range are beyond the allowed range as well. They are mainly used by personal users or licensed or authorized institutions that are authorized or licensed to do that. For example, military frequency channels and emergency rescue channels are generally freelanced.
As with the USA, most of the European Union’s authorized channels are free. However, the exception is channel 6, which is a military frequency used exclusively by the Armed Forces. It is used by the police and also by anyone interested in emergency rescue and communications. Other channels which are commonly found in an amateur radio station’s cb radio frequency chart are those related to music and TV programs such as music channels, sport channels, religious channels, sex and violence, and other educational channels.
There are also channels which are considered to be part of the global spectrum which are not allowed to use certain frequencies and are hence considered to be pirate frequencies as well. These channels are often being blocked by operators who want to use these frequencies for their own gain and control others from doing so. This is one of the main reasons why there are some countries whose communication systems are being blocked and interfered with by freeband operators. In fact, the United States Federal Communications Commission has stated that these pirate radio operators are causing millions of dollars of loss to US companies by using freehand frequencies and interfering with communications systems.
