*Question G2C05:
What is the best speed to use when answering a CQ in Morse code?*  

*Correct Answer is  B: The fastest speed at which you are comfortable copying, but no faster than the CQ*  

### AI Response: (may contain errors)  

When answering a CQ (a general call) in Morse code, it's important to ensure effective communication. Here's why the correct answer is the best choice:

1. **Correct Answer: B - The fastest speed at which you are comfortable copying, but no faster than the CQ**

   - **Explanation**: The goal is to match the speed of the person calling CQ to ensure they can comfortably copy your response. If you send at a speed faster than the CQ, the calling station may not be able to copy your message, leading to communication breakdown. By sending at a speed you are comfortable with, you ensure accuracy in your transmission.

2. **Why the Other Choices are Incorrect**:
   - **Choice A**: "The fastest speed at which you are comfortable copying, but no slower than the CQ"
     - This choice suggests you should not go slower than the CQ, which might pressure you to send faster than you are comfortable with, increasing the chance of errors.
   
   - **Choice C**: "At the standard calling speed of 10 wpm"
     - There is no standard calling speed in Morse code. The speed should be adjusted based on the CQ speed and your comfort level.
   
   - **Choice D**: "At the standard calling speed of 5 wpm"
     - Similar to Choice C, there is no standard speed of 5 wpm. This speed might be too slow for the calling station, leading to inefficient communication.

3. **Rules of Thumb**:
   - Always aim to match or slightly adjust to the speed of the station calling CQ.
   - Prioritize clear and accurate communication over speed.

By following these guidelines, you ensure that both you and the calling station can effectively communicate in Morse code.
