What does the Q code QRM mean?

• A. Stand by
• B. Location
• C. I have interference
• D. Time

Answer: (C)

Q codes are concise shorthand used in radio communications to convey common situations quickly. QRM is the code that specifically signals interference on the frequency. When you’re transmitting and another station’s signal is overlapping or distorting what you’re trying to hear, you’d use QRM to indicate that you’re experiencing interference. This helps others understand why your communications are unclear and often prompts them to adjust the frequency, pause, or take steps to reduce the clash. In contrast, the other possibilities refer to different ideas: one is associated with standby or delay needs, another with location information, and another with time. None of those describe interference, which is why the meaning of QRM is the interference code.
