*Question G2A10:
Which of the following statements is true of VOX operation versus PTT operation?*  

*Correct Answer is  B: It allows “hands free” operation*  

### AI Response: (may contain errors)  

In the context of VOX (Voice Operated Switch) operation versus PTT (Push-To-Talk) operation, let's break down the correct answer and the reasoning behind it.

### Correct Answer: B - It allows “hands free” operation

- **Explanation**: 
  - VOX operation automatically activates the transmitter when it detects your voice, allowing you to speak without needing to press a button. This is particularly useful in situations where you need to use both hands, such as when operating equipment or driving.

### Why the Other Choices are Incorrect:

- **A: The received signal is more natural sounding**  
  - **Explanation**: The sound quality of the received signal is not inherently better with VOX than with PTT. Both methods can produce similar audio quality; it depends more on the equipment and settings used rather than the method of operation.

- **C: It occupies less bandwidth**  
  - **Explanation**: Bandwidth usage is determined by the modulation scheme and the signal itself, not by whether VOX or PTT is used. Both methods can occupy the same bandwidth depending on the transmission characteristics.

- **D: It provides more power output**  
  - **Explanation**: The power output of the transmitter is not affected by whether VOX or PTT is used. The transmitter will output the same power level regardless of the method of activation, assuming the same settings are used.

### Summary

- VOX allows for hands-free operation, making it convenient for multitasking.
- The other options do not accurately reflect the differences between VOX and PTT operation in terms of audio quality, bandwidth, or power output. 

This understanding will help you differentiate between these two operating modes on the exam.
