[CQ-Contest] Summarizing the Skimmer Accuracy Thread

[W0MU Mike Fatchett]

Great tool!  I guess about 12 people failed to copy what K3LR actually 
sent for their zone LOL.  I wonder how loud those people were copying 
K3LR.  Zone 21 is pretty rare and to hear them 20 or 30 over should make 
one wonder, right?
