[Dx4win] Error in dupe check for import of ADIF

[Gunnar Widell]

Hi,

I have two logfiles,  one with 229 thousands of QSO's in DX4WIN ver8 
format, and another in ADIF format containing 226 thousand. They should 
be about the same. Now I want to merge these two, using the dx4win log 
as a master and just add new qsos from the ADIF.

After trying to import, dx4win reports around new 126 thousand qsos. I 
do select "Imported QSO is Ignored" when starting the import.  I see 
lots of dupes in the resulting logfile.

Is dx4win looking at other things than Date, time and callsign to 
determine if a qso is a dupe?
