*Question T2A06:
Which of the following is required when making on-the-air test transmissions?*  

*Correct Answer is  A: Identify the transmitting station*  

### AI Response: (may contain errors)  

To understand the requirements for making on-the-air test transmissions, let's analyze the question and the choices provided.

### Correct Answer: A - Identify the transmitting station

- **Explanation**: According to FCC regulations, all amateur radio operators must identify their station during transmissions. This is typically done by sending your call sign at the beginning and end of a transmission, and at regular intervals during longer transmissions. This requirement ensures that other operators know who is transmitting and helps maintain proper communication protocols.

### Why the Other Choices are Incorrect:

- **B: Conduct tests only between 10 p.m. and 6 a.m. local time**  
  - **Explanation**: There is no specific time restriction for conducting test transmissions in amateur radio. Operators can conduct tests at any time, provided they follow the identification rules and do not cause interference.

- **C: Notify the FCC of the transmissions**  
  - **Explanation**: Amateur radio operators are not required to notify the FCC before making test transmissions. However, they must operate within the rules and regulations set forth by the FCC, including proper identification.

- **D: All these choices are correct**  
  - **Explanation**: Since choices B and C are incorrect, this option cannot be correct either.

### Summary

When making on-the-air test transmissions, the only requirement is to identify your transmitting station. This is crucial for compliance with FCC regulations and for maintaining good operating practices in amateur radio.

### Key Rule of Thumb

- Always identify your station with your call sign during any transmission, including tests. This is a fundamental rule in amateur radio operation.
