What does the code "QRN" mean in amateur radio?

In the Q code system, "QRN" means "I am troubled by static." This code is specifically used when a station's reception is being degraded by atmospheric noise, thunderstorms, or natural solar static. An easy way to remember this is to associate the "N" in QRN with "Nature" or "Natural" interference. This helps operator easily differentiate it from human-caused signal issues. The distractors represent other common Q codes: "I am being interfered with" (by other stations) is QRM, and "I am busy" is QRL.
