What a joke contesting has become. Send  your call using the exact 
formula   below so  the robot can copy your call otherwise people 
cannot work you.
N6TJ in the last century said packet doomed real contesting. He was 
right!

>Send CQ TEST and YOURCALL at the same speed
>If you send your call twice in a CQ, leave an extra half space between the 1st and 2nd instance of your call
>If you have a call that is often busted by humans, (ie, TN copied as G or C) use extra spacing to lower skimmer busts

>There are techniques for minimizing busted skimmer (or human) spots from showing up on your bandmap/logging software:

>Use software like VE7CC;s AR User to limit skimmers to those that are geographically meaningfully to you, and to spots that are meaningful to the contest.
>Use the settings in N1MM or other contest software (blacklisting/available mult/Q window filtering, etc) to minimize display of meaningless spots.
>
>When jumping on spots, throw in a little XIT dither of 50 -200 hz to avoid the zero beat lemmings leaping on spots problem.
