[CQ-Contest] Split operation in CQ WW CW

I'd add just a note on spots ...   The real problem is people jumping on 
spots and all winding up on the same frequency, even if it is not 
zero-beat with the DX.  It rarely will be anyway, and a little judicious 
tweaking of the XIT control, or even (heaven forbid) tuning to center 
the DX in your pass-band while he signs, should bring you nicely out of 
the ruck without anyone having to send "up one" or whatever.  I'm sure 
Bob was talking about the up 5 splits, not something within 300 Hz or so.
