*Question G3C09:
What type of propagation allows signals to be heard in the transmitting station’s skip zone?*  

*Correct Answer is  B: Scatter*  

### AI Response: (may contain errors)  

To understand why "Scatter" is the correct answer for the type of propagation that allows signals to be heard in the transmitting station’s skip zone, let's break down the options:

### Correct Answer: Scatter
- **Explanation**: Scatter propagation occurs when radio waves reflect off irregular surfaces, such as buildings, trees, or the atmosphere. This type of propagation can allow signals to reach areas that are not directly in line of sight with the transmitter, including the skip zone. The skip zone is the area between the transmitter and the point where the signal reflects back to Earth, and scatter can fill this gap.

### Why the Other Choices are Incorrect:
1. **A: Faraday rotation**
   - **Explanation**: Faraday rotation refers to the rotation of the plane of polarization of radio waves as they pass through a magnetic field, such as the Earth's magnetic field. This phenomenon does not directly relate to the skip zone and does not facilitate signal reception in that area.

2. **B: Scatter**
   - **Explanation**: This is actually the correct answer, as explained above. It allows signals to be heard in the skip zone.

3. **C: Chordal hop**
   - **Explanation**: Chordal hop refers to a specific type of propagation where signals bounce off the ionosphere at an angle, creating a shorter path than typical skip propagation. While it can allow for some signal reception, it does not specifically address the skip zone in the same way that scatter does.

4. **D: Short-path**
   - **Explanation**: Short-path propagation refers to the direct path a signal takes between two points, typically over the surface of the Earth or through the ionosphere. This does not involve the skip zone, as it implies a direct line of sight rather than the indirect paths that scatter propagation utilizes.

### Summary
- **Scatter propagation** is the only option that effectively allows signals to be heard in the skip zone due to its ability to reflect off various surfaces and reach areas that are not directly aligned with the transmitter. 

Understanding these concepts will help you grasp the nuances of radio wave propagation and prepare effectively for the Extra Class exam.
