CB radio users have their own lingo, including RST code, ten codes, Q-code, phonetic alphabet and slang. RST-code is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an assessment of the signal’s readability, strength, and tone. The code was developed in the early 20th century and was in wide-spread use by 1912.
NATO phonetic alphabet, more formally the international radiotelephony spelling alphabet , is the most widely used spelling alphabet. Though often called ” phonetic alphabets “, spelling alphabets have no connection to phonetic transcription systems like the International Phonetic Alphabet. Instead, the NATO alphabet assigns code words to the letters of the English alphabet acrophonically (Alfa for A, Bravo for B, etc.) so that critical combinations of letters (and numbers) can be pronounced and understood by those who transmit and receive voice messages by radio or telephone regardless of their native language, especially when the safety of navigation or persons is essential. The paramount reason is to ensure intelligibility of voice signals over radio links.
Q-code is a standardized collection of three-letter message encodings, all starting with the letter “Q”, initially developed for commercial radiotelegraph communication, and later adopted by other radio services, especially amateur radio. Although Q codes were created when radio used Morse code exclusively, they continued to be employed after the introduction of voice transmissions. To avoid confusion, transmitter call signs have often been limited to restrict ones starting with “Q” or having an embedded three-letter Q sequence. The codes in the range QAA-QNZ are reserved for aeronautical use; QOA-QOZ for maritime use, and QRA-QUZ for all services.
Ten(10)-codes, properly known as ten signals, are code words used to represent common phrases in voice communication, particularly by law enforcement and in Citizen’s Band (CB) radio transmissions. The codes, developed in 1937 and expanded in 1974 by the Association of Public Safety Communication Officials (APCO), allow for brevity and standardization of message traffic. They have historically been widely used by law enforcement officers in North America, although some departments have controversially attempted to prohibit their use.
CB slang (commonly called “CB Talk”) are terms that those operating CB radio used mainly during the CB craze of the 1970s and 1980s. Some of these slang terms are still in use with their original meanings, others not used at all and some have changed meaning.
When transmitting or receiving, it is very useful to be able to give and receive useful and consistent signal reports.
It helps to guide how to conduct the contact. To achieve this, a system known as the RST
reporting system is normally used.
As the name indicates, the RST reporting system is based around three numbers.
One is for Readability (R), one is for Strength (S), and one is for Tone (T). The tone is only used for Morse code transmissions.
The meanings for the different numbers are given in the table below:
2 Barely readable
3 Readable with difficulty
4 Readable with little difficulty
5 Perfectly readable
S1 Barely detectable
2 Very weak signals
3 Weak signals
4 Fair signals
5 Fairly good signals
6 Good signals
7 Moderately strong signals
8 Strong signals
9 Very strong signals
T1 Extremely rough note
2 Very rough note
3 Rough note
4 Fairly rough note
5 Note modulated with strong ripple
6 Modulated note
7 Near DC note but with smooth ripple
8 Near DC note but with trace of ripple
9 Pure DC note
