*Question G2B01:
[97.101(b), (c)] Which of the following is true concerning access to frequencies?*  

*Correct Answer is  C: Except during emergencies, no amateur station has priority access to any frequency*  

### AI Response: (may contain errors)  

In the context of amateur radio operations, understanding frequency access is crucial. Here's a breakdown of the correct answer and why the other choices are incorrect:

1. **Correct Answer: C - Except during emergencies, no amateur station has priority access to any frequency**

   - **Explanation**: The FCC rules, specifically 97.101(b) and (c), state that no amateur station has priority access to any frequency except during emergencies. This means that all amateur radio operators must share the frequencies and operate in a cooperative manner, ensuring that everyone has fair access. The only exception is during emergency communications, where certain stations may take precedence to facilitate urgent communications.

2. **Why the Other Choices are Incorrect**:

   - **Choice A: Nets have priority**
     - **Explanation**: While nets (organized on-air meetings) are common in amateur radio, they do not have inherent priority over other communications. Operators are encouraged to cooperate and accommodate nets, but there is no regulatory priority given to them.

   - **Choice B: QSOs in progress have priority**
     - **Explanation**: A QSO (a conversation between two or more amateur radio operators) does not have priority over other communications. Operators should be courteous and avoid interrupting ongoing QSOs, but there is no formal priority granted by the rules.

   - **Choice D: Contest operations should yield to non-contest use of frequencies**
     - **Explanation**: While it is good practice for contest operators to be considerate of non-contest activities, there is no rule that mandates contest operations must yield. The emphasis is on mutual respect and cooperation among all operators.

3. **Useful Rules of Thumb**:

   - **Cooperation and Courtesy**: Always strive to operate in a manner that is courteous and cooperative, respecting ongoing communications and being willing to share frequencies.
   - **Emergency Communications**: Remember that emergency communications take precedence over all other types of amateur radio operations.

By understanding these principles, you can ensure compliance with FCC regulations and promote a positive operating environment on the amateur bands.
