[Elecraft] Backward CW?

[KJ3D]

 Well here comes the probably-stupid-question-of-the-day:

After nearly 90 minutes on the NAQCC sprint last night - sending and
answering dozens of calls, some from pretty strong signals - without a
single contact, I gotta wonder if the problem is on my end.

How can I tell if my carrier is on the correct side of zero-beat?  

Then how do I fix it?  

Have I even asked the right question?

Thanks es 73,
