The Q-code is a standardized collection of three-letter codes all starting with the letter Q, such as QRM. First, the Q-code is sent in Morse code three times as either a statement or a question. Then it is spoken. And finally, it is sent again in Morse code. If you missed something the first time when it was sent, the second time allows you an opportunity to learn it.
