*Question E2C06:
During a VHF/UHF contest, in which band segment would you expect to find the highest level of SSB or CW activity?*  

*Correct Answer is  C: In the weak signal segment of the band, with most of the activity near the calling frequency*  

### AI Response: (may contain errors)  

During VHF/UHF contests, operators typically focus on making contacts over long distances using weak signal modes like SSB (Single Sideband) and CW (Continuous Wave). Here's why the correct answer is choice C:

1. **Correct Answer (C):**  
   - **Weak Signal Segment:** This part of the band is specifically designated for modes that are effective over long distances, such as SSB and CW.  
   - **Activity Near Calling Frequency:** Contest activity is often concentrated around the calling frequency because it serves as a common point for operators to initiate contacts before moving to other frequencies.

2. **Why Other Choices Are Incorrect:**
   - **Choice A:**  
     - **Top of Each Band:** This area is not typically reserved for contests. Contest activity is more about weak signal work, not just any segment at the top.
   - **Choice B:**  
     - **Middle of Each Band/National Calling Frequency:** The national calling frequency is used for initial contact but is not where the majority of contest activity occurs. Operators usually move off the calling frequency to complete contacts.
   - **Choice D:**  
     - **Middle of the Band/25 kHz Above National Calling Frequency:** This is not a standard practice for contest activity. The focus is on the weak signal segment, not a fixed offset from the calling frequency.

3. **Useful Rules of Thumb:**
   - **Calling Frequencies:** These are starting points for making contact but not where most contest activity remains.
   - **Weak Signal Work:** Focus on segments designated for weak signal modes to maximize contact opportunities during contests.

Understanding these band usage patterns helps operators efficiently participate in contests and make the most of their operating time.
