I am the JA coordinator and aware that I am not in a position to say something here, but I would rather prepare a separate log file containing one correct QSO with KB3WAV and upload it, in this case. I think there is no WB33WAV staion and this uploading will cause any serious problem.
The number of contacts by N5PHT will be one more than real number until the wrong log data is deleted, but no problem either.
Pit, YO3JW, the WWFF Award Manager and the YOFF coordiantor, suggested similar ways to get minor errors corrected promptly in the informal Skype meeting of the WWFF committee yesterday.
