At first, users were required to obtain a CB Radio license and call letters from the FCC to operate a CB Radio. However, the FCC was so inundated with requests for CB Radio licenses that they finally abandoned formal licensing and allowed operators to buy CB Radio equipment and go on the air without any license or call letters.

Although no license is required to operate a CB Radio, FCC Laws Part 95, Subpart D, which contains the FCC's rules for CB Radio operation, are still in effect. These rules cover CB Radio equipment, the ban on linear amplifiers, and the types of communications permitted on the air.


You are authorized to operate your 40-channel CB Radio set from:
The 50 United States
District of Columbia
Commonwealth of Puerto Rico
Navassa Island
United States Virgin Islands
Pacific insular areas
Any other area of the world, except within the territorial limits of areas where CB Radio services are regulated by any agency other than the FCC or any foreign government, or aboard an aircraft or ship where the captain disallows CB Radio use.


CB Radio Channel 9 may be used only for emergency communications or for traveler's assistance. Members of the Radio Emergency Associated Communications Teams (REACT) throughout the United States do an excellent job of guarding CB Radio Channel 9 specifically for emergencies or requests for directions. REACT is a non-profit public service organization. Its thousands of members can take advantage of REACT headquarters programs, which include group insurance, conventions, team newsletters, and special CB Radio equipment discounts.


CB Radio operators normally transmit double sideband AM on the first 23 channels. On channels above Channel 23, upper sideband or lower sideband equipment may be used. Four watts of carrier power is allowed for output on AM, and 12 watts of peak envelope power is the maximum power output on SSB. You may only use a type-accepted CB Radio transmitter. Any internal modification to a type-accepted CB Radio transmitter cancels the type acceptance, and use of such a transmitter voids your authority to operate the station. The same type regulation applies to power amplifiers. Power amplifiers are specifically disallowed for use with a CB Radio.


Your CB Radio base antenna system may be erected 20 feet higher than the highest point of the building or tree on which it is mounted; however, the highest point of the antenna must not be more than 60 feet above the ground. There are additional restrictions on an antenna system located near an airport. Consult FCC Laws Part 95, Subpart D for your particular situation.


Since an FCC license is not required for the CB Radio service, you do not need to identify your CB Radio communications. However, the FCC encourages you to identify your communications on CB Radio by any of the following means:

Previously assigned CB Radio call sign
K prefix, followed by operator initials and residence zip code
Name of organization or individual
A "handle"- an easily-recognized, fictitious name you choose to identify yourself over the CB radio airwaves.
A formal call-sign issued to you by a recognized CB Radio organization or club.


You may use your CB Radio station to transmit 2-way, plain-language communications concerning your personal or business activities, or those of members of your immediate family living in your household. You can also transmit 2-way emergency communications, traveler assistance, and civil defense activities to other CB Radio sets. You may use an audible tone lasting no more than 15 seconds to "tone call" other CB Radio stations. You may also use your CB Radio station to transmit 1-way communications for emergency communications, traveler assistance, voice paging, or brief radio checks. The latter occurs mostly when you do not know if any other CB Radio stations are within your transmitting range.

The FCC regulates how far you can communicate with your CB Radio station 155.3 miles is the limit. The FCC also wants you to limit your CB Radio communications to the minimum practical time.


The FCC makes it clear that CB Radio may not be used:

In connection with any activity which is against federal, state, or local law
To transmit obscene, indecent, or profane words
To intentionally interfere with other CB Radio operators
To advertise or solicit the sale of any goods or services
To transmit music, whistling, sound effects
To transmit the word "Mayday" unless it's an absolute emergency
To advertise political candidates
To transmit to other stations not in the CB Radio service
To transmit communications for live or delayed rebroadcast over a commercial radio or TV station.


During daylight hours, sporadic-E propagation will usually cause CB Radio signals to bounce off the ionosphere, and come back down thousands of miles away. Many CB Radio operators enjoy "shooting skip," but this is in violation of the FCC rules. "Skip shooting" is so popular and prevalent on the bands that there is very little enforcement for this common violation. In fact, recent studies by licensed amateur radio operators show that many good hams are born out of the CB Radio service. The CB Radio operators become frustrated with the amount of channel congestion between Channels 1 and 40 and go for a ham radio operator's license. Ham radio is a natural step for these operators who love the thrill of talking long distances. The new no-code ham license is just for them.

Some CB Radio operators illegally modify their CB Radio equipment and wander beyond Channel 40 to the bottom edge of the ham 10-meter band. The FCC takes quick action to close down these pirate CB Radio stations. First offenders are typically fined over $1,000 for their "out of band" operation.

CB Rule 20 allows you to have someone at a receiving CB Radio base station make a manual connection to the telephone. This is called "phone patch." It patches your CB Radio transmission into the normal telephone system. In the CB Radio service, it is allowed if there is:

Someone to supervise the operation of the phone patch.
Someone that listens to each communication during the patch.
Someone who may stop the communication if there is a violation of the rules.

With over 10 million CB Radio Operators using CB Radio, the 40-channel CB Radio service serves as a valuable means for roadside assistance. One of the fastest ways to make radio contact out on the highways is over CB Radio.

Out on the open highway, the trucking industry makes good use of CB Radio by constantly using and monitoring specific frequencies, usually those between Channel 9 and Channel 23. With thousands of truckers using these channels, it's a cinch for the motorist, hiker, or base station to summon help. The truckers are quick to come to the aid of someone calling "Mayday" on one of their often-used channels. Many of these overland carriers also have cellular phones so they may be able to quickly relay your call to the proper authorities.
