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.
