*Question T1E08:
[97.3(a)(6), 97.205(d)] Which of the following is an example of automatic control?*  

*Correct Answer is  A: Repeater operation*  

### AI Response: (may contain errors)  

To understand the concept of automatic control in amateur radio, let's analyze the question and the provided choices.

### Correct Answer: A - Repeater operation

- **Why it's correct**: 
  - A repeater operates automatically by receiving a signal and retransmitting it without human intervention. This is a classic example of automatic control, as the repeater continuously monitors its input and output without needing a person to operate it.

### Why the other choices are incorrect:

- **B: Controlling a station over the internet**: 
  - This involves remote control, which requires human input to operate the station. While it can be automated to some extent, it does not fit the definition of automatic control as it still relies on a person to initiate and manage the operation.

- **C: Using a computer or other device to send CW automatically**: 
  - While this may seem like automatic control, it typically requires a human to set up the parameters and initiate the process. The computer sends the CW (Continuous Wave) signal, but it is not a fully autonomous operation.

- **D: Using a computer or other device to identify automatically**: 
  - Automatic identification is a function that can be performed by a device, but it is not considered automatic control of the station itself. It is more about compliance with regulations rather than controlling the operation of the station.

### Summary

- **Automatic Control**: Refers to systems that operate independently without human intervention, like repeaters.
- **Key Point**: Repeater operation is a clear example of automatic control, while the other options involve some level of human interaction or do not control the station's operation directly.

This understanding will help you recognize examples of automatic control in amateur radio for the Extra Class exam.
