What does the Q signal “QRN” mean?
The correct answer is D: I am troubled by static. The Q signal 'QRN' means 'I am troubled by static'. This is used to report that static (atmospheric noise) is interfering with reception. For amateur radio operators, this helps communicate reception conditions. Understanding this helps when operating and reporting conditions. QRN is about static interference, not other types of interference.
Exam Tip
QRN = I am troubled by static. Think 'Q'RN = 'Q'uery 'R'eception 'N'oise (static). Means 'I am troubled by static' - atmospheric noise interference. Not about speed, stopping, or zero beat - just static interference.
Memory Aid
"QRN = I am troubled by static. Think 'Q'RN = 'Q'uery 'R'eception 'N'oise. Means 'I am troubled by static' - atmospheric noise interference. Standard Q signal for reporting static conditions."
Real-World Application
You're operating on 80 meters during a thunderstorm. Static crashes are making reception difficult. You send 'QRN' to report that you're troubled by static. This helps the other operator understand your reception conditions. QRN specifically refers to atmospheric static, not other interference.
Key Concepts
Why Other Options Are Wrong
Option A (Send more slowly): Incorrect. 'Send more slowly' is 'QRS,' not 'QRN.' QRN is about static, not speed.
Option B (Stop sending): Incorrect. 'Stop sending' is 'QRT,' not 'QRN.' QRN is about static interference.
Option C (Zero beat my signal): Incorrect. This isn't a standard Q signal meaning - zero beat is a tuning procedure, not a Q signal. QRN is about static.
