CB 10-CODES

Citizens Band radio operators have largely adopted the “10-code”for standard questions and answers. Its use permits faster communications and better understanding in noisy areas. The following table lists some of the more common codes and their meanings:

Be sure the antenna is properly connected to the radio before transmit-

ting. Prolonged transmitting without an antenna, or use of a poorly

matched antenna, could cause damage to the transmitter.

2. When asking for aid on Channel 9 it is suggested that you request a

REACT base to respond by saying "Break Channel 9 for a REACT base"

and provide the CB DISTRESS DATA (called "CLIP):

CALL SIGN-Identify yourself and vehicle.

LOCATION-Be exact.

INJURIES-Number. Type. Trapped?

PROBLEM- Give details and help required. Air CLIP repeatedly so any monitor can aid you.

If you don't receive a response on Ch. 9; try Ch.14 or 19.

FCC gives the following examples of permitted and prohibited types of communications for use on Channel 9. These are guidelines and are not intended to be all-inclusive.
