*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)  

The correct answer to the question about where to find the highest level of SSB or CW activity during a VHF/UHF contest is:

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

### Explanation of the Correct Answer:
- **Weak Signal Segment**: This segment is specifically designated for SSB (Single Sideband) and CW (Continuous Wave) operations, which are common modes used in contests. 
- **Calling Frequency**: Contest activity often clusters around established calling frequencies, making it a prime area for finding operators actively participating in contests.

### Why the Other Choices are Incorrect:
- **A: At the top of each band, usually in a segment reserved for contests**  
  - While contests may occur at the top of some bands, this is not universally true for all VHF/UHF bands. The highest activity is typically found in the weak signal segments rather than just at the top.

- **B: In the middle of each band, usually on the national calling frequency**  
  - The national calling frequency is often used for initial contacts but does not represent the highest level of contest activity, which tends to be more concentrated in the weak signal segments.

- **D: In the middle of the band, usually 25 kHz above the national calling frequency**  
  - This option suggests a specific frequency offset that does not align with typical contest practices. Contest activity is more focused on the weak signal areas rather than a fixed offset from the calling frequency.

### Useful Rules of Thumb:
- **Contest Frequencies**: Familiarize yourself with the specific band plans for VHF/UHF, as they outline where SSB and CW operations are encouraged.
- **Calling Frequencies**: Know the national calling frequencies for the bands you operate on, as these are often starting points for contest operations.

By understanding these concepts, you can better navigate the band segments during contests and maximize your chances of making contacts.
