*Question G2B05:
When selecting an SSB transmitting frequency, what minimum separation should be used to minimize interference to stations on adjacent frequencies?*  

*Correct Answer is  C: 2 kHz to 3 kHz*  

### AI Response: (may contain errors)  

When selecting an SSB (Single Sideband) transmitting frequency, it's important to minimize interference to adjacent stations. The correct answer is:

**C: 2 kHz to 3 kHz**

### Explanation of the Correct Answer:
- **Minimum Separation**: The recommended minimum frequency separation for SSB transmissions is typically between 2 kHz and 3 kHz. This distance helps ensure that the sidebands of your transmission do not interfere with adjacent channels, which is crucial for maintaining clear communication and reducing interference.

### Why the Other Choices are Incorrect:
- **A: 5 Hz to 50 Hz**: This range is too narrow. Such a small separation can lead to significant interference, especially since SSB signals can have sidebands that extend beyond the carrier frequency.
  
- **B: 150 Hz to 500 Hz**: While this range is better than A, it is still insufficient for SSB transmissions. The sidebands can extend well beyond this range, leading to potential interference with adjacent frequencies.

- **D: Approximately 6 kHz**: This range is unnecessarily wide. While it would certainly minimize interference, it exceeds the typical requirement for SSB operations, which is generally around 2 kHz to 3 kHz.

### Summary:
To minimize interference to adjacent stations when selecting an SSB transmitting frequency, aim for a separation of **2 kHz to 3 kHz**. This ensures that your transmission remains clear and does not encroach on the frequencies of nearby operators.
