Q-CODES
I have recently had the pleasure of assisting a fellow member of Staff at work by helping him train to become a radio amateur. Chris is an electrical lecturer at the college where we both work, I was extremely happy when Chris asked me to help him get into the hobby and with his electrical/electronic knowledge it will be fairly simple to pass the foundation examination and obtain the licence which will allow him to operate his recently purchased yaesu ft-847.
Good luck with the exam Chris and welcome to the world of Ham radio.

Chris asked me about Q-codes so I decided to post the list of Q-codes which are used by radio amateurs around the world. The Q-codes were originally invented for use with telegraphy and then Morse code allowing messages to be transmitted quickly without having to rattle out long and difficult sentences. These days they are still used as a way of sending voice messages as well as Morse, whilst communicating with another station. The Q-codes can be very useful especially when two stations in communication with each other may not speak the same language as the Q-codes are a universal language.

QRG Exact frequency
QRI Tone (T in the RST code) UR QRI IS 9
QRK Intelligibility (R in the RST code) UR QRK IS 5
QRL This frequency is busy. Used almost exclusively with Morse code, usually before transmitting on a new frequency
QRM Man-made interference ANOTHER QSO UP 2 kHz CAUSING LOT OF QRM
QRN Natural interference, e.g. static crashes BAND NOISY TODAY LOT OF QRN
QRO Increase power NEED QRO WHEN PROP POOR
QRP decrease power QRP TO 5 W
QRQ Send faster TIME SHORT PSE QRQ
QRR temporarily unavailable/away, please wait WILL BE QRR 30 MIN = THAT STN IS QRR NW
QRRR Distress Distress call recommended by ARRL
