*Question G2C10:
What does the Q signal “QRN” mean?*  

*Correct Answer is  D: I am troubled by static*  

### AI Response: (may contain errors)  

The Q signal "QRN" is used in amateur radio to indicate that the operator is experiencing interference from static or noise.

### Explanation of the Correct Answer:
- **Correct Answer: D: I am troubled by static**
  - "QRN" specifically refers to the presence of static noise that affects the quality of the received signal. When an operator sends "QRN," they are communicating that they are having difficulty hearing due to static interference.

### Explanation of Incorrect Answers:
- **A: Send more slowly**
  - This is not correct because the Q signal for sending more slowly is "QRS." "QRN" does not imply a request to adjust the speed of transmission.

- **B: Stop sending**
  - The Q signal for stopping transmission is "QRT." "QRN" does not convey a request to cease communication.

- **C: Zero beat my signal**
  - The term "zero beat" refers to tuning your frequency to match another signal for optimal reception, which is indicated by "QSB" for fading signals. "QRN" does not relate to tuning or frequency matching.

### Summary:
- **QRN** = I am troubled by static
- **QRS** = Send more slowly
- **QRT** = Stop sending
- **QSB** = Fading signals

Understanding these Q signals helps in effective communication and clarifies the context of the messages being exchanged in amateur radio operations.
