[UK-CONTEST] Valid QSOs

[David Ferrington, M0XDF]

I'm now loosing track of this thread, but I believe Chris, G3SJJ said  
that

#	op	transmission
-	------	----------------
1	Chris	TEST G3SJJ
2	Alex	GM3ZBE
3	Chris	GM3ZBE 5NN51
4	Alex	5NN21
5	Chris	TU G3SJJ


is correct.

I also think someone is saying that because line 4 from Alex does not  
include G3SJJ, it isn't.

But aren't the rules covered by the fact that Alex has already give  
Chris's callsign in line 2?

Being new to this and not done any CW contests (but the basic  
structure is used on HF and VHF regardless of mode), would someone  
please post what is the correct exchange (ignoring things like  
PostCode or Locator) if the above is not?
