*Question T8C04:
Which of the following is good procedure when contacting another station in a contest?*  

*Correct Answer is  C: Send only the minimum information needed for proper identification and the contest exchange*  

### AI Response: (may contain errors)  

In a contest, effective communication is crucial due to the high volume of stations trying to make contact. Let's break down the correct answer and the reasoning behind it.

### Correct Answer: 
**C: Send only the minimum information needed for proper identification and the contest exchange.**

- **Explanation**: In a contest, efficiency is key. You should provide just enough information to identify yourself and complete the required exchange. This typically includes your call sign and the specific contest exchange (like your signal report or location). Sending unnecessary information can lead to confusion and may cause you to miss other contacts.

### Why the Other Choices are Incorrect:

- **A: Sign only the last two letters of your call if there are many other stations calling**  
  - **Explanation**: This is not a good practice. While it may seem like a way to save time, it can lead to misidentification. Always provide your full call sign to ensure clarity and proper logging by the other station.

- **B: Contact the station twice to be sure that you are in his log**  
  - **Explanation**: Repeating your contact is generally unnecessary and can waste time during a contest. If you provide your call sign and the required exchange clearly, the other station should log you correctly without needing a repeat.

- **D: All these choices are correct**  
  - **Explanation**: Since A and B are incorrect, this choice cannot be correct. Only C is the appropriate procedure.

### Summary:
In contests, the goal is to maximize the number of contacts in a limited time. Therefore, sending only the essential information (your call sign and contest exchange) is the best practice. This helps maintain the flow of communication and ensures that both stations can log the contact efficiently.
