2012 CQ WPX CW Log Check Report

Summary 13.9% Score Reduction
Not In Log
Incorrect Call
Incorrect Exchange Information

Let’s start with my score summary as I took a 13.9% (n = 376,208) score reduction as a result of not in log, incorrect call, and incorrect exchange information. I mentioned in my previous post there is cause and effect when the score is officially adjudicated.

Likewise, there is perspective, as I claimed (n = 1,588 Qs) and my final was (n = 1,506 Qs) or 2.9% of calls copied incorrectly (n = 46) and 2.0% incorrect exchange information (n = 32) with 0.3% not in the log (n = 4).

Subsequently, 376,208 points was subtracted from my claimed total of 2,699,166 points (2,699,166 – 2,322,958 = 376,208 point reduction).

The question I’m asking of my performance, “What is my root cause?”

There is a definitive pattern when reviewing incorrect callsigns and incorrect exchange information. If I were to scatter plot then a picture emerges that is the preponderance of evidence suggests missed dits and missed dahs of letters-to-numbers and numbers-to-numbers.

For example, SH8MU corrected to S58MU, SH0XX corrected to S50XX, or IH3EO corrected to S53EO, SH2ZW corrected to S52ZW, and SH9ABC corrected to S59ABC.

Examples of incorrectly copied numbers such as 228 corrected to 238 or 275 corrected to 285.

Root cause analysis suggests I am not hearing crucial dits/dahs and cannot be explained away as mistakes at the keyboard. The solution is carefully listen or ask for a repeat if there is any question about either callsign or exchange information.

What patterns are you seeing in your log check report?
