Which Q code indicates you should change channels?

• A. QSM
• B. QSY
• C. QTR
• D. QRU

Answer: (B)

Change channels is signaled by QSY. This code means you should switch your radio to a different frequency or channel to continue communications. In practice, when someone instructs QSY, you tune to the new channel or frequency specified so you can coordinate with the right units or handle traffic more efficiently. Other codes referenced have different purposes: one is a request to repeat the last message, not a channel change; another is used to ask or state the time; and another indicates you have no further traffic to send. None of these instructs you to switch channels.
