*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)  

VOX (Voice Operated Exchange) and PTT (Push-To-Talk) are two different methods of keying a transmitter in amateur radio operations.

1. **Correct Answer: It allows “hands free” operation (Choice B)**  
   - **Explanation**: VOX operation automatically activates the transmitter when you start speaking, allowing you to operate the radio without needing to press a button. This is particularly useful when you need to keep your hands free for other tasks.

2. **Why the other choices are incorrect**:
   - **Choice A: The received signal is more natural sounding**  
     - VOX operation does not affect the sound quality of the received signal. The naturalness of the sound is determined by the audio processing and transmission quality, not by the method of keying the transmitter.
   
   - **Choice C: It occupies less bandwidth**  
     - The bandwidth of a transmission is determined by the modulation method and the signal processing, not by whether VOX or PTT is used. Both methods occupy the same bandwidth for a given mode of operation.
   
   - **Choice D: It provides more power output**  
     - The power output of a transmitter is independent of whether VOX or PTT is used. Power output is determined by the transmitter settings and capabilities, not the keying method.

3. **Useful Information**:
   - VOX is convenient for hands-free operation but can be sensitive to background noise, which might inadvertently trigger the transmitter.
   - PTT requires manual activation, which can be more reliable in noisy environments as it only transmits when the button is pressed.
