How to Develop Code & Communicate With a Scanner

1Purchase a scanner, which is a radio used to transmit information. Scanners, sometimes called police scanners or 2 way radios, range in price from $100 or less to more than $1,000, depending on their specifications. Less-expensive scanners work well for personal use, such as monitoring transmissions for hobby or personal safety. Units that are more expensive are used by police and fire departments to provide stronger frequencies and outputs that are more powerful. Most electronics stores and online auction websites sell scanners.
2Set up your scanner by following the instructions that came with the unit. Find frequencies for various agencies by searching the dial or by looking up the official frequency on the agency’s website. Consult RadioReference.com for a database of frequencies for organizations throughout the United States.
3Learn the communication code. Police codes use codes with the prefixes “10-” and “11-” followed by numbers that correspond to various situations. For example, “10-4″ means “message received.” Long-haul truckers use a different set of codes to communicate. In the language of truckers, for example, the term “alligator” means there is a blown tire in the road, and a “salt shaker” is a snowplow.
4Develop your own code for communicating. If you are using your radio to communicate with someone, discuss terms you would like to codify for your own radio language. Consider using the police or trucker codes as a base to work from when developing your own code language. For example, think of a nickname for the town you live in or a code word for the street you live on.
5Record your codes and distribute the information to others who will be using the information. You can do this with a notebook, computer document or online database, which all code users can modify when they think of a new code word.
