*Question T3B08:
What frequency range is referred to as VHF?*  

*Correct Answer is  B: 30 MHz to 300 MHz*  

### AI Response: (may contain errors)  

The correct answer to the question about the VHF frequency range is:

**B: 30 MHz to 300 MHz**

### Explanation of the Correct Answer:
- VHF stands for Very High Frequency, which is defined by the Federal Communications Commission (FCC) and the International Telecommunication Union (ITU).
- The VHF range specifically covers frequencies from $30 \text{ MHz}$ to $300 \text{ MHz}$. This range is commonly used for FM radio broadcasting, television broadcasts, and two-way radio communications.

### Why the Other Choices are Incorrect:
- **A: 30 kHz to 300 kHz**
  - This range falls within the Low Frequency (LF) band, not VHF.
  
- **C: 300 kHz to 3000 kHz**
  - This range is known as the Medium Frequency (MF) band, which includes AM radio frequencies, but it does not reach into the VHF range.
  
- **D: 300 MHz to 3000 MHz**
  - This range is classified as Ultra High Frequency (UHF), which is above the VHF range.

### Useful Rules of Thumb:
- Remember the frequency bands:
  - **LF**: 30 kHz to 300 kHz
  - **MF**: 300 kHz to 3 MHz
  - **HF**: 3 MHz to 30 MHz
  - **VHF**: 30 MHz to 300 MHz
  - **UHF**: 300 MHz to 3 GHz

This classification helps in identifying the frequency ranges and their respective uses in amateur radio and other communications.
