I think Phil is referring to

GU0SUP GU0SUP DE W7AY W7AY W7AY

as a 2x3  (i.e. two of the other persons callsign and three of your 
own).


In a contest, I usually only send a 0x2. I.e., if I am answering 
someone else's CQ, I send

carriage return
W7AY W7AY
carriage return

the two carriage returns are to place a barrier between line noise and 
what I send.  The reason for sending two of my own calls instead of one 
is that it is an error checking mechanism.  If he sees the same 
callsign repeated, he pretty well knows that he is printing correctly.  
If he prints "W7AY W7AT" he can send QRZ? or W7 AGN?

In a CW contests, I send my call only once, no DE.  Most of the 
experienced contesters seem to prefer hearing that.  SSB contests?  
Lets not go there... :-)

Sending his callsign when you call him is not really needed; and anyone 
who sends a 3x3 should be flogged :-).  As Phil stated, he already 
knows his own callsign.  No additional information is passed.  Thus DE 
is not needed either.

I only (finally) send his callsign when I send the exchange.  This way, 
he is assured that it is he that I worked, and not another person on 
the same frequency who he is not hearing, i.e.,

GU0SUP QSL 599 OR OR 3 W7AY

That said, I sent not a single callsign last weekend.  I wasn't 
anywhere near my radio, HI HI.
