[Moon-net] QSO or not?

[jimmyv at hol.gr]

Hello all
 
I am trying to understand how JT65 works sometimes (even without Deep Search!),
especially when it comes to expeditions. I am confused. 
Could you please explain to me how is possible to have a QSO as complete in the
log of an expedition, when the station calling them says it is not complete?
However, expedition says it has data files for all QSOs. So does the station
trying to work them. So where is the error? 
This is even more profound because in the case of JT65 it is even more difficult
to make a personal judgement mistake. Since software algorithms do the decision
making for you and we have been told that reliability of a contact remains
intact. Regardless of signal level.

As i do not question the integrity and experience of operators in the specific
expedition (in fact they are experienced operators with good operating
standards), neither do i question the experience and integrity of the
particular station calling them, then is it the JT65 software generating the
error? I think, and hope, not.
 
Perhaps is it the plain shorthand messages? To me, it looks like this being the
reason, because shorthand messages are not accompanied with callsigns (unless
the Big exception of someone transferring both reports and callsigns as unknown
text). Therefore, using the standard format of shorthand messages, in a pileup
situation, one can not be sure if the RO or Rs received was for him or
not...(as logger extract shows below at 5:19)
We have seen situations with other expeditions in the past.
 
To substantiate my argument and subsequent confusion with facts, pls find below
extracts of ON4KST logger showing PE1BTX saying to ZB2/DH7FB he did not have
complete QSO with ZB2 expedition. At the end of this mail, pls see the log of
ZB2 expedition where QSO is listed as complete.
 
Once more, i will repeat this is nothing personal and NOT aiming the operators
involved; the specific case is merely used as another example. But just
scratching my head as to how some QSOs eventually take place and the totally
different outcomes reached. Your help in understanding what is happening is
appreciated!
 
Thanks in advance & 73,
Jimmy SV1BTR

05:26:40 PE1BTX Gerard 4X12/QRO Frank, but despite my NC congrats on your FB
operation, you gave a lot of stations a new DXCC 
05:24:05 DH7FB frank gerard, yes in next time we will also do this 
05:19:50 PE1BTX Gerard 4X12/QRO Frank, could be, pse look my EME log
http://www.pe1btx.nl/EME%20initials%20all%20bands.htm 
05:19:16 DH7FB frank gerard, so the received "ro" came fm another stn maybe 
05:16:17 PE1BTX Gerard 4X12/QRO Yep, NC for me, but already wkd ZB2IQ back in
1983 on ES, and confirmed 
05:13:57 PE1BTX Gerard 4X12/QRO Found my QSO complete in the log, but never
send RO to him on 21st, so not complete for me, did not even had a decent decode
on 21st, very strange
