Q-code - an international three-letter code used in radio communications (marine, amateur, usually - when transmitting Morse code ).
The meaning of the code depends on whether it is transmitted as a question, that is, with a question mark after the actual Q-code, or as an assertion.
In the communications forces of the Armed Forces of the USSR, Q-codes were called Щ-codes, since the Cyrillic letter "Щ" and the Latin "Q" correspond to the same Morse code.

Currently, many codes have slightly changed their meaning. For example, QRM and QRN transmit without a score; QSL also means a receipt card confirming the fact of communication; QRP in amateur radio almost always does not mean a request to reduce power, but the fact of working with low power (not higher than 5-10 W), etc.
Special Codes
In addition to expressions related to radio communications per se, the Q-code includes hundreds of specific expressions used in ship navigation, air traffic control, weather services, rescue services, radio direction finding, etc. For example, according to the Soviet rules of radio exchange:
- SHM - “Prepare dinner for the crew of so many people”;
- SCHKA - “I saved people and follow the base, having so many people on board”;
- SCHUL - “The sea state at the indicated point is such-and-such (on a 9-point scale)”
- ЩСЦ - “I am a cargo ship”;
- SCHUSCHCH - “Point your searchlight up at the clouds, giving, if possible, a blinking light; when my plane is visible or audible, direct the beam against the wind towards the water (earth) to facilitate my landing. ”
Unofficial Codes
Amateurs use informal ( jargon ) expressions derived from Q-codes, for example, QRPP means working with extremely low transmitter power (1 W or less), QSLL - "I will send you a QSL card as soon as I receive yours."
There are also comic extensions of the official code, usually understood by a certain circle of initiates. They are used not so much in radio exchange as in related conversations. Some examples:
| Code | With a “?” | Unsigned “?” |
|---|---|---|
| QBA | ( English big antenna ) Do you have a large antenna ? | I have a big, big antenna! |
| QBS | ( English bird shit ) Is your antenna covered with bird droppings? | Shake the shit off the antenna and hear me. |
| QDR | ( English do you have receiver? ) Do you have a receiver ? (in response to “QRL?”) | Yes, damn it ( English damn right ), the frequency is busy! |
| QEW | ( English earwax ) Do you have gray ears? | I don’t hear you, my ears are full. |
| QKB | ( eng. knobs ) How many control knobs does your radio have? | At my station ... pens. |
| QKN | ( English know how ) And how many pens do you know how to use? | I can use ... pens. |
| QLF | ( English left foot ) Do you work on the key with your left foot? | I work on the key with my left foot. |
| QRC | Are you a chew of rags? ( English rag chewer - a lover of long conversations [1] ) | Caution, on the air talker. |
| QZZ | Is it 60 Hz background or are you snoring ? | I fall asleep at the microphone . |
