An email with a link to the Log Checking Report has been sent to everyone who submitted a log for the CQ WW DX Contest CW 2013. The Log Checking Report includes a complete summary of how the final score was calculated and any errors or deductions that may have occurred. We make these reports available so participants can have the opportunity to learn from their mistakes.

How does your accuracy compare to others? The chart below shows the number of errors by percentage and the cumulative percentage of entrants in that bin.
