*Question T7B10:
What might be a problem if you receive a report that your audio signal through an FM repeater is distorted or unintelligible?*  

*Correct Answer is  D: All these choices are correct*  

### AI Response: (may contain errors)  

To understand why the correct answer is "All these choices are correct," let's break down each option:

1. **Your transmitter is slightly off frequency**:
   - If your transmitter is not precisely on the repeater's frequency, it can cause distortion. FM signals are sensitive to frequency deviations, and being off frequency can lead to poor audio quality or unintelligible signals.

2. **Your batteries are running low**:
   - Low battery voltage can affect the performance of your transmitter. Insufficient power can lead to distortion in the audio signal, as the transmitter may not be able to maintain the necessary modulation levels.

3. **You are in a bad location**:
   - Physical obstructions, such as buildings or terrain, can interfere with the signal path. If you are in a location with poor line-of-sight to the repeater, the signal may be weakened or distorted, resulting in unintelligible audio.

Since all these factors can contribute to audio distortion when using an FM repeater, the correct answer is indeed "All these choices are correct."

### Summary of Choices:
- **A**: Correct, as frequency accuracy is crucial for clear FM transmission.
- **B**: Correct, as low battery power can degrade signal quality.
- **C**: Correct, as location affects signal propagation and clarity.

### Useful Rule of Thumb:
- Always ensure your transmitter is properly tuned to the repeater frequency, check battery levels, and choose a location with a clear line of sight to the repeater for optimal performance.
