*Question E1B10:
[97.407] What frequencies are authorized to an amateur station operating under RACES rules?*  

*Correct Answer is  A: All amateur service frequencies authorized to the control operator*  

### AI Response: (may contain errors)  

The correct answer to the question about frequencies authorized to an amateur station operating under RACES (Radio Amateur Civil Emergency Service) rules is:

**A: All amateur service frequencies authorized to the control operator.**

### Explanation of the Correct Answer:
- Under RACES rules, amateur operators are allowed to use all frequencies that they are normally authorized to use as part of their amateur license. This means that if a control operator holds an Extra Class license, they can operate on all amateur frequencies available to that class.

### Why the Other Choices are Incorrect:
- **B: Specific segments in the amateur service MF, HF, VHF, and UHF bands**  
  This choice implies that there are limitations to certain segments, which is not the case under RACES. Operators can use any frequency they are authorized for, not just specific segments.

- **C: Specific local government channels**  
  RACES does not restrict operators to local government channels. Instead, it allows the use of all amateur frequencies, which may include local government frequencies only if they are also authorized for amateur use.

- **D: All these choices are correct**  
  Since choices B and C are incorrect, this option cannot be correct either. The correct answer is solely A.

### Summary:
- RACES allows amateur operators to use all frequencies they are authorized for, without restriction to specific segments or channels. This flexibility is crucial for emergency communications, where operators may need to utilize any available frequency to establish contact.

### Useful Rule of Thumb:
- Always refer to your specific amateur license class to determine which frequencies you are authorized to use, especially in emergency situations like those governed by RACES.
