Just for fun, try a search for "EK*" on reversebeacon and see what you get...

One way this might happen is if you send your call twice and your call ends in a 

dit (like K3LR). The final dit of the call could be interpreted as a separate E. 
This is worse
if you use the "shortened inter-word spacing" setting for CW generation. I would 
suggest 

inserting an extra half-space between sending your call twice if it ends in a 
dit.

But random impulse noise could also generate a dit sometimes- that is harder to 
control.
