*Question E1D10:
[97.211] Which amateur stations are eligible to be telecommand stations of space stations, subject to the privileges of the class of operator license held by the control operator of the station?*  

*Correct Answer is  B: Any amateur station so designated by the space station licensee*  

### AI Response: (may contain errors)  

In this question, we are discussing which amateur stations can serve as telecommand stations for space stations. The correct answer is based on the authority and designation given by the space station licensee.

### Explanation:

1. **Correct Answer: B - Any amateur station so designated by the space station licensee**
   - The space station licensee has the authority to designate which amateur stations can act as telecommand stations. This means that the licensee can choose specific amateur stations to control or communicate with the space station, as long as the control operator holds the appropriate class of operator license.

2. **Why the Other Choices are Incorrect:**
   - **Choice A: Any amateur station approved by AMSAT**
     - AMSAT (Radio Amateur Satellite Corporation) is an organization that promotes amateur radio satellites, but it does not have the authority to designate telecommand stations. The designation must come from the space station licensee.
   - **Choice C: Any amateur station so designated by the ITU**
     - The ITU (International Telecommunication Union) is a global organization that regulates radio communications, but it does not designate specific amateur stations for telecommand purposes. This responsibility lies with the space station licensee.
   - **Choice D: All these choices are correct**
     - Since only the space station licensee can designate telecommand stations, this choice is incorrect.

### Key Points:
- The space station licensee is responsible for designating telecommand stations.
- The control operator of the designated station must hold the appropriate class of operator license.
- Neither AMSAT nor the ITU has the authority to designate telecommand stations for space stations.
