CB FAQ.

CB is a band of radio frequencies set aside for use by citizens. CB has few regulations and does not require any technical knowledge.

Not in America or England. Some other countries may still require a licence.

The distance you will get contacts over will depend on several factors. Things that may affect distance include your height, surroundings, hills, buildings, antenna type and power output.
In some countries, such as America, there may be laws regarding how far you can communicate. For more information, see the reference section.

ANYONE. It's really that simple, it is there for anyone and everyone.

The Citizens Band was set up for general communication between members of the public. CB can be used both from fixed base stations and from vehicles such as cars, trucks, motorcycles... even bicycles, or on foot.

You are not supposed to use CB on board an aircraft. Also, there may be restrictions if you live near an airport.
It is not intended for private communications, it is more like a community.
It is not intended for long distance communications, although there are times when contact can be made with people in other countries.

Although businesses can usually use CB, you must remember that the service does NOT provide private communications.

This will depend upon what you want to use CB for and how involved you want to get.
For a list of requirements in different situations, check out the equipment section on this site.

On CB, people usually just speak normally now. The old 10 codes are not often used, I doubt if many CBers would even know more than the really common ones.
Sometimes, you may hear three letter codes used, beginning with a "Q". These are called the Q codes. Although not often used on CB, it can be useful to know the common ones.

These depend upon the country. Please see the reference section for more details of frequencies and standards.
