[Dx4win] DX4Win/LoTW help and advice please - Again!

Thu Jul 9 07:33:55 EDT 2009

Pete,

As I understand it, the LoTW upload process adds all new records, which are automatically marked as active QSOs. If a duplicate (previous upload) QSO exists, it is marked as "inactive" - but never deleted. Your total QSO count will increase, but if you perform a Query on your QSOs you will only see the active records, not the duplicate inactive records.

  I'm confused. Here is a section from a relatively recent activity report from LOTW in which I inadvertently overlapped with a previous upload.  LOTW appears to be reporting a replacement, not an additional duplicate record.

2008-11-20 21:27:29 LOTW_QSO:  QSO record QSLs a contact
2008-11-20 21:27:29 LOTW_QSO:     QSO: N4ZR N6HC 2008-01-12 21:53:20Z 20M CW
2008-11-20 21:27:30 LOTW_QSO:  [Additional QSL notices suppressed]
2008-11-20 21:30:29 LOTW_QSO:  WARNING: QSO replaces existing record
2008-11-20 21:30:29 LOTW_QSO:     QSO: N4ZR ZC4LI 2008-03-15 12:08:28Z 20M CW
2008-11-20 21:30:32 LOTW_QSO:  WARNING: QSO replaces existing record
2008-11-20 21:30:32 LOTW_QSO:     QSO: N4ZR EU1PA 2008-03-15 12:08:55Z 20M CW
2008-11-20 21:30:32 LOTW_QSO:  WARNING: QSO replaces existing record
...

But at the end of the report, it says:

"1919 records were duplicates"

But my DX4WIN says 102966 QSOs, and LOTW says 106,867 records, which would seem to suggest that Larry is correct, and I have overlapped at least once before.  But then why say "replaces existing record"?

Andy,

    Aha... you have just uncovered an intentional design feature of LoTW: 
uploaded records cannot be deleted. Even if you upload the EXACT SAME QSO 
records a second time, LoTW adds new records and your QSO count discrepancy 
between DX4Win and LoTW will increase.

  I could reset the upload flags and upload the whole log but would that 
help?
    No. Your LoTW QSO record count will double and your problem will remain.

  There is obviously a discrepancy somewhere...
    My uneducated guess is that when you  "also added some very old QSOs" to 
LoTW they were already there - part of an earlier upload that you forgot 
about? You now have 10 duplicate records. Or {as I have done} when I 
discover an error with an already-uploaded QSO in DX4Win, I correct the 
error and re-upload the QSO. In that case, the old wrong QSO is still there 
along with the new corrected QSO. [Aha... another intentional design feature 
of LoTW: uploaded records cannot be edited.]

You have a QSO-count discrepancy that will not go away, and your best 
approach is to be diligent in tracking future uploads so that you don't 
increase the gap. Some users upload their entire log EVERY TIME they upload 
{imagine their discrepancy!} which is why you may get more than one 
notification of a QSO match. You get notified (a downloaded QSO ADIF 
record)every time that person re-uploads a QSO that matches with yours.

There are lots of good architectural reasons why LoTW prohibits record 
deletions, so rather than argue with ARRL's design team it's best to just 
understand how LoTW works and "get over it." ;-) The reality is that LoTW is 
not really a "logbook", but more closely resembles "eHarmony.com for QSOs." 
Some QSOs find more than one match {kinda reminds me of some politicians in 
the News lately!} while others are a 1:1 relationship.

  I have just uploaded 24 recent 6m QSOs to LoTW but have a glitch. The
actual upload was for 27 QSOs as I also added some very old QSOs into my 
log
for some QSL cards that I found for some contacts back in the 1980s.  When
the QSOs were uploaded every thing seemed OK but I noticed that my total 
log
QSOs in DX4Win is 15455 but LoTW shows 15466. Until this upload my log and
LoTW concurred. It was not rejected nor was a discrepancy high lighted 
until
I tried to download the report. When I did this I got a window in DX4Win
saying "Upload aborted duplicate QSO A7/M0GFA". I have looked at the
activity report and it says "no discrepancy found" and also says that
amongst others it found a QSL for A7/M0FGA.

There is obviously a discrepancy somewhere but I cannot find it. Can I go
back and delete the last up load and repeat it? Would that solve the
problem? I could reset the upload flags and upload the whole log but would
that help? There are some really good QSLs in addition to the A7 that I
would like to get correctly into DX4Win.

Thank you for any help and suggestions.
