*Question E1D12:
[97.207(e), 97.203(g)] Which of the following amateur stations may transmit one-way communications?*  

*Correct Answer is  A: A space station, beacon station, or telecommand station*  

### AI Response: (may contain errors)  

To understand which amateur stations may transmit one-way communications, we need to look at the definitions and regulations governing these types of stations.

### Correct Answer: A space station, beacon station, or telecommand station

1. **Space Station**: This type of station operates in space and can transmit signals back to Earth without requiring a response. It is designed for one-way communication.
  
2. **Beacon Station**: A beacon transmits signals for the purpose of providing information, such as location or time, and does not expect any response from receiving stations. This is inherently a one-way communication.

3. **Telecommand Station**: This station sends commands to a remote device (like a satellite) and does not require a return communication. It is also classified as one-way.

### Why the Other Choices are Incorrect:

- **B: A local repeater or linked repeater station**: 
  - Repeaters are designed to receive signals and retransmit them, which means they facilitate two-way communication. They do not operate as one-way stations.

- **C: A message forwarding station or automatically controlled digital station**: 
  - Message forwarding stations typically handle two-way communications, as they relay messages between users. Similarly, automatically controlled digital stations often engage in two-way exchanges, responding to incoming signals.

### Summary

- **One-way communication** is allowed for:
  - Space stations
  - Beacon stations
  - Telecommand stations

- **Two-way communication** is required for:
  - Local repeaters
  - Message forwarding stations
  - Automatically controlled digital stations

This distinction is crucial for understanding the operational capabilities of different amateur radio stations as per FCC regulations.
