CB (or Citizen Band) Radios are still widely used by long haul truckers. They can also be fun for hobbyists and unlike Ham radio there is no license required. You can basically pick up and go. BUT if you want to fit in you better know the lingo. An introduction to CB and some handy lingo from Right Channel Radios:
Outside of slang (which we’ll go over in a bit), most coded language over a CB radio takes the form of something called a “10 code”. You may be familiar with some of these from popular culture, as they’re often used in movies and television whenever a truck driver is depicted using his or her CB radio. These 10 codes are often also used by police and emergency responders in the media as well. In fact, these codes were originally created for emergency responders by the Association of Public-Safety Communications Officials International in the late 1930s and expanded again in the 1970s. While many emergency responders have begun to move away from them in favor of plain speech, you can still hear the unmistakable cadence of 10 codes just about every time you turn on your CB.
