*Question G1B03:
[97.3(a)(9)] Which of the following is a purpose of a beacon station as identified in the FCC rules?*  

*Correct Answer is  A: Observation of propagation and reception*  

### AI Response: (may contain errors)  

In the context of the FCC rules, a beacon station is specifically used for the purpose of observing propagation and reception. Let's break down why this is the correct answer and why the other choices are incorrect:

1. **Correct Answer: Observation of propagation and reception**
   - Beacon stations are designed to transmit signals at regular intervals. These signals can be monitored by other stations to study and analyze radio wave propagation conditions. This helps amateur radio operators understand how signals travel over various distances and through different atmospheric conditions.

2. **Why the other choices are incorrect:**
   - **Automatic identification of repeaters (Choice B):** This is not a function of a beacon station. Repeaters may have their own identification systems, but this is separate from the purpose of a beacon.
   - **Transmission of bulletins of general interest to amateur radio licensees (Choice C):** This is typically the role of a bulletin station, not a beacon station. Bulletin stations are used to disseminate information to the amateur radio community, which is different from the propagation study purpose of beacons.
   - **All these choices are correct (Choice D):** Since only one of the choices (A) is correct, this option is incorrect.

In summary, the primary role of a beacon station is to assist in the study of radio wave propagation by providing a consistent signal that can be monitored and analyzed. This is why "Observation of propagation and reception" is the correct answer.
