*Question G2E08:
In what segment of the 20-meter band are most digital mode operations commonly found?*  

*Correct Answer is  D: Between 14.070 MHz and 14.100 MHz*  

### AI Response: (may contain errors)  

In the 20-meter amateur radio band, digital mode operations are most commonly found between 14.070 MHz and 14.100 MHz. This is the correct answer because:

1. **Correct Answer (D: Between 14.070 MHz and 14.100 MHz):**
   - This frequency range is specifically allocated for digital modes like PSK31, RTTY, and other similar digital communications. It is a well-known segment for digital enthusiasts and is widely used for these purposes.

2. **Why the Other Choices are Incorrect:**
   - **Choice A (At the bottom of the slow-scan TV segment, near 14.230 MHz):**
     - This frequency is typically used for slow-scan television (SSTV) operations, not digital modes. SSTV involves sending images over radio and is distinct from digital text or data modes.
   - **Choice B (At the top of the SSB phone segment, near 14.325 MHz):**
     - This part of the band is used for single sideband (SSB) voice communications. Digital modes are not commonly found here as it is primarily for voice operations.
   - **Choice C (In the middle of the CW segment, near 14.100 MHz):**
     - The CW (Continuous Wave) segment is primarily for Morse code operations. While some digital modes might occasionally be found near the edges, the main digital activity is not centered here.

**Rules of Thumb:**
- Digital modes have specific sub-bands within amateur radio bands where they are most active.
- Knowing these sub-bands helps in efficiently finding and participating in digital communications.

Understanding these allocations helps ensure that operators use the correct frequencies for their intended mode of operation, promoting efficient and interference-free communication.
