Q-codes are used in many kinds of radio communications, including CB sideband but not typically on CB AM. (If your radio doesn't have sideband, don't worry about Q-codes.) Q-codes originated with amateur radio but their use in CB, even more so than 10-codes, can vary depending on who published the list.
The following is an abbreviated list of Q-codes borrowed from amateur radio:
· QRM-man made noise, adjacent channel interference
· QRN-static noise
· QRO-increase power
· QRP-reduce power
· QRT-shut down, clear
· QSL-confirmation, often refers to confirmation cards exchanged by hams
· QSO-conversation
· QSX-standing by on the side
· QSY-move to another frequency
· QTH-address, location
Possible uses of the codes:

On SSB it sometimes becomes difficult to understand skip stations or low down stations, but on AM it isn't. So when radio communications started up they invented the Phonetic alphabet.
