Q-Code

These codes were oringinally developed to shorten transmission times when using CW, but are frequently used in voice transmissions eg. I and going to go QRT, thanks for the QSO.

More information abut the history and usage of Q-codes can be found here.

Code Meaning Sample use
Q Codes Commonly Used by Radio Amateurs
QRG Exact frequency HE TX ON QRG 14205 kHz
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
QRS Send slower PSE QRS NEW TO CW
QRT Stop sending ENJOYED TALKING 2 U = MUST QRT FER DINNER NW
QRU Have you anything for me? QRU? ABOUT TO QRT
QRV I am ready WL U BE QRV IN UPCOMING CONTEST?
QRX will call you again QRX @ 1500H
QRZ You are being called by ________. QRZ? UR VY WEAK (Only someone who has previously called should reply)
QSA Signal strength UR QSA IS 5
QSB Fading of signal THERE IS QSB ON UR SIG
QSD Your keying is defective QSD CK YR TX
QSK Break-in I CAN HR U DURING MY SIGS PSE QSK
QSL I Acknowledge receipt QSL UR LAST TX = PSE QSL VIA BURO (i.e. please send me a card confirming this contact).
QSM Repeat last message QRM DROWNED UR LAST MSG OUT = PSE QSM
QSN I heard you QSN YESTERDAY ON 7005 kHz
QSO A conversation TNX QSO 73
QSP Relay PSE QSP THIS MSG TO MY FRIEND
QST General call to all stations QST: QRG ALLOCS HV CHGD
QSX I am listening on ... frequency QSX 14200 TO 14210 kHz
QSY Shift to transmit on ... LETS QSY UP 5 kHz
QTA Disregard last message QTA, DID NOT MEAN THAT
QTC Traffic STN WID EMRG QTC PSE GA
QTH Location QTH IS SOUTH PARK CO
QTR Exact time QTR IS 2000 Z


RST code

Number R - Readability S - Strength T - Tone
RST Code Commonly Used by Radio Amateurs
1 Unreadable Faint signal, barely perceptible Sixty cycle a.c or less, very rough and broad
2 Barely readable, occasional words distinguishable Very Weak Very rough a.c., very harsh and broad
3 Readable with considerable difficulty Weak Rough a.c. tone, rectified but not filtered
4 Readable with practically no difficulty Fair Rough note, some trace of filteringfrequency
5 Perfectly readable Fairly Good Filtered rectified a.c. but strongly ripple-modulated
6 not used Good Filtered tone, definite trace of ripple modulation
7 not used Moderately Strong Near pure tone, trace of ripple modulation
8 not used Strong Near perfect tone, slight trace of modulation
9 not used Very strong signals Perfect tone, no trace of ripple or modulation of any kind


RSV code for SSTV transmissions

Number R - Readability S - Strength V - Video
RST Code Commonly Used by Radio Amateurs
1 Unreadable Faint signal, barely perceptible Picture unreadable
2 Barely readable Very Weak picture barely visible
3 Readable with difficulty Weak Readable with flaws
4 Readable with no difficulty Fair Very good picture some flaws
5 Perfectly readable Fairly Good Perfect picture no flaws
6 not used Good not used
7 not used Moderately Strong not used
8 not used Strong not used
9 not used Very strong signals not used
