*Question T1B06:
[97.301(e), 97.305] On which HF bands does a Technician class operator have phone privileges?*  

*Correct Answer is  B: 10 meter band only*  

### AI Response: (may contain errors)  

The correct answer to the question about HF bands where a Technician class operator has phone privileges is:

**B: 10 meter band only.**

### Explanation:

1. **Why the correct answer is correct:**
   - Technician class operators are allowed to use voice (phone) communications on the 10 meter band, specifically in the portion of the band from 28.300 MHz to 28.500 MHz. This is the only HF band where they have phone privileges.

2. **Why the other choices are incorrect:**
   - **A: None** - This is incorrect because Technician class operators do have phone privileges on the 10 meter band.
   - **C: 80 meter, 40 meter, 15 meter, and 10 meter bands** - This is incorrect because Technician class operators do not have phone privileges on the 80 meter, 40 meter, or 15 meter bands. They can only use CW (Morse code) on those bands.
   - **D: 30 meter band only** - This is incorrect because Technician class operators do not have phone privileges on the 30 meter band. They are allowed to use only CW on this band.

### Useful Rules of Thumb:
- **HF Band Privileges for Technicians:**
  - Phone privileges are limited to the 10 meter band.
  - Other HF bands (80m, 40m, 15m, and 30m) are restricted to CW only for Technician class operators.

This information is crucial for understanding the operating privileges of different license classes in amateur radio.
