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:

Going QRT	Switching off now
Receiving QRM	I'm getting interference from another station
Having QRN trouble	Having static trouble.
That was a quick QSO!	That was a quick chat!
QSY to channel...	Go to channel...
CQDX CQDX...	Seek you long distance, seek you long distance.
What's your QTH	What's your location?

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.

A=Alpha
B=Bravo
C=Charlie
D=Delta
E=Echo
F=Foxtrot
G=Golf
H=Hotel
I=India
J=Juliet
K=Kilo
L=Lima
M=Mike
N=November
O=Oscar
P=Papa
Q=Quebec
R=Romeo
S=Sierra
T=Tango
U=Uniform
V=Victor
W=Whiskey
X=X-ray
Y=Yankee
Z=Zulu
