[CQ-Contest] Summarizing the Skimmer Accuracy Thread

K3LR is not using full break-in on any band. There is no distortion detected
on the TX RF scope pattern. Amplifier vacuum relays are pulled in before any
TX RF is applied by using the Win-Test PTT option.

We'll try the extra half space option between K3LR's in November.

If this works, lots of guys will be disappointed that they will miss the
rare EK3 multiplier during CQWW CW 2013.

I guess Bob argument is biased on EK3LR events.  There are less than 100
wrong spots from USA Skimmers.  One would also expect similar EK9CT errors
but there are only 5.  No EK1ZZ or EK9NW.  Only 16 errors of EW3LPL.  Only
one EU Skimmer G0KTN made EK3LR single error out of 330 proper spots.
Average human error rate on CW is around 3 %.  Not for Z6/S56A!

I suspect K3LR is using full break-in at legal power which distorts CW
envelope causing random timing errors.  We can learn a lot from RBN!
