[Dx4win] Lotwreport.notfound file

Tue Mar 1 18:20:55 EST 2011

 Hi Jim, if I could add a bit of what I have observed on this.

You are correct with the . In the left column.  Not much we can do about
that, if people keep uploading their whole logs over and over they will keep
showing up on this list.  For those LoTW users who do this, you may not
think it a problem but it can be.

The X is a little more complex than just QSO not found.

For example.  I get a fair number of X in the left column and it is usually
a station in the USA.  This happens because they have shifted QTH to another
state or county but not requiring a callsign change.  So now it shows up on
the not found list, NOT because the QSO is not in the log but the
information contained in the QSO record does not match.  Being made aware of
this may be a good thing but it is difficult to know which is the correct
information.  For example a QSO shows up in the not found list marked X when
I click on it in the QSO not found box and get potential matches, sure
enough there is an obvious match, call, date, time, mode, band all match but
the county is different, both county information coming from LoTW.  This
could mean several things.  The first information is wrong and the recent
upload is an attempt to correct an error. IMHO unlikely.  Second it could be
simply that the station has shifted QTH and have changed their location
information when doing uploads but unfortunately they upload their whole log
overwriting all previous QSO's with incorrect information for the previous
time period.

So to sum up DX4WIN is working correctly but unfortunately other peoples
actions are generating lots of noise in these reports.  Unfortunately I must
admit this does make one tend to ignore the report completely as in both of
the cases above no logical action can be taken.

The number in the right-hand column is the group number of the QSO, from
your log.  My understanding is that if the group number is NOT zero, then
the QSO was found in your log.  It could also be zero if no group number was
assigned to that QSO.

If there is a small dot (like a period) in the left-hand column (as shown
below), the QSO was already confirmed via LoTW (from a previous
import).   If there is an 'X', then the QSO from LoTW was NOT found in
your log (and the group number will be (0) zero).
