I have been unable to import an ADIF file in to QRZ Logbook since March. I asked this question on the QRZ forum; they said ask NetLogger forum. I tried to attach the file to this question, but it said it's in the wrong format.
So I guess the export file is not creating the correct extension.
I am using a Mac, and have tried to export files in NetLogger 3.1.5 and 3.1.7
Thank you 73, Doug
