*Question T3C07:
What band is best suited for communicating via meteor scatter?*  

*Correct Answer is  B: 6 meters*  

### AI Response: (may contain errors)  

To determine the best band for communicating via meteor scatter, we need to consider the characteristics of different frequency bands and how they interact with meteor trails in the atmosphere.

### Correct Answer: 6 meters (Choice B)

- **Why it's correct**: The 6-meter band (50-54 MHz) is particularly effective for meteor scatter communications because:
  - It falls within the VHF range, which is suitable for short-duration reflections caused by meteor trails.
  - The frequency is high enough to allow for effective propagation but low enough to take advantage of the ionization created by meteors, which can reflect signals over long distances.

### Why the Other Choices are Incorrect:

- **33 centimeters (Choice A)**:
  - This band (902-928 MHz) is too high for effective meteor scatter. The higher frequency results in less ionization and shorter reflection times, making it less suitable for this mode of communication.

- **2 meters (Choice C)**:
  - While the 2-meter band (144-148 MHz) can be used for meteor scatter, it is not as effective as the 6-meter band. The reflections are generally shorter and less reliable compared to those on the 6-meter band.

- **70 centimeters (Choice D)**:
  - Similar to the 33-centimeter band, the 70-centimeter band (420-450 MHz) is also too high for optimal meteor scatter communication. The higher frequency limits the effectiveness of reflections from meteor trails.

### Summary

- **Best Band for Meteor Scatter**: 6 meters (50-54 MHz)
- **Other Bands**: Less effective due to higher frequencies and shorter reflection times.

Understanding these characteristics will help you choose the right band for meteor scatter communications during the exam and in practical applications.
