*Question E1F07:
[97.113] When may an amateur station send a message to a business?*  

*Correct Answer is  D: When neither the amateur nor their employer has a pecuniary interest in the communications*  

### AI Response: (may contain errors)  

In amateur radio, the Federal Communications Commission (FCC) has specific rules about communications that involve a pecuniary interest, which means any financial or commercial interest.

### Explanation:

1. **Correct Answer: D - When neither the amateur nor their employer has a pecuniary interest in the communications**

   - **Why it's correct:** The FCC rules prohibit amateur radio operators from using their stations for any communications in which they or their employers have a financial interest. This is to ensure that amateur radio remains a non-commercial service focused on personal and technical development, rather than business or profit-making activities.

2. **Why the other choices are incorrect:**

   - **Choice A:** "When the pecuniary interest of the amateur or his or her employer is less than $25"
     - **Incorrect because:** Any pecuniary interest, regardless of the amount, is not allowed. The rule does not set a monetary threshold below which pecuniary interest is permissible.

   - **Choice B:** "When the pecuniary interest of the amateur or his or her employer is less than $50"
     - **Incorrect because:** Similar to choice A, the rule prohibits any pecuniary interest, and there is no monetary threshold that makes it acceptable.

   - **Choice C:** "At no time"
     - **Incorrect because:** While this choice seems strict, it is not entirely accurate. Amateur stations can send messages to businesses as long as there is no pecuniary interest involved. For example, a message could be sent for non-commercial purposes, such as coordinating a public service event.

### Key Rule:

- **FCC Rule [97.113]:** Amateur stations cannot be used for communications in which the operator or their employer has a pecuniary interest. This ensures that amateur radio is used for personal enjoyment, education, and public service, rather than commercial purposes.
