RADIO COMMUNICATION CODES
Citizens Band radio operators have universally adopted
the "10" Code for standard questions and answers. It
enables them to communicate faster, easier and more
understandably in noisy surroundings.
The following are some of the most common codes and
their descriptions.
When using the code 10-1, you would say, "Ten one",
not "One zero dash one".
