Lee,
I'm not sure why adding your grid would make any difference.  Don't most 
folks mention their grid when calling CQ?  It tells me which way the 
turn the antenna when that weak CQ is coming in off the side, and it's 
pretty common practice:  "CQ TEST K0SM/2 FN13 K."  I don't see how this 
is "self-spotting" in any sense of the word.  Why would it be any 
different with simplex digital modes, whether it is AX25, FSK441, or RTTY?

FWIW, many of the serious contesters have been using FSK441 in contests 
for nearly 2 years now, before that it was HSCW.  It makes the wee hours 
of the morning good for something other than sleep :-)
