Which Q code means Stand by?

• A. QTR
• B. QSL
• C. QSM
• D. QRX

Answer: (D)

Q codes are a compact set of three-letter prowords used in radio communication to convey common actions quickly. Stand by is represented by the code QRX. When you send or hear QRX, you’re telling the other station to pause and wait for further instructions or for you to get back to them shortly. It’s a way to keep the channel clear while you handle something on your end or confirm details before continuing. Other codes in this set have different meanings, which is why they don’t fit for “Stand by.” For example, one code asks for or states the time, another is used to acknowledge receipt of a message, and another asks to relay a message to a different station. Those meanings are distinct from the instruction to pause communications.
