Hi, I have posted this message a couple of times and am still looking for an answer. What is the quickest, most efficient way to recognize and elminate dulpicate QSOs in DX4WIN? This would include merged DX4WIN files and imported ADIF files. All of the QSOs, whether generated within DX4WIN or imported, would be contained within a single DX4WIN log. Is there any simple way to do this? Thanks, Rick WO8L
