I have two K3s and now a new K3S.  I not sure the sync card makes much difference, but the noise reduction is now outstanding.

 Bob,

I noticed an improvement right away just by tuning 
20 CW during a very active contest weekend. My 
ability to pull out weak signals was much enhanced.

But I do agree completely with you for Bill's 
purposes "I don't contest or DX - just rag chew on 
160/75/40... ".

I am very skeptical of those who claim to have noticed a difference without having done an actual A/B comparisons.  Far too many factors at play.
