Hi again! I'm still don't know, what to do. The "Upload Date" field in my log is not empty. I still can't edit it (but manually for each QSO). Moreover, I can't export another ADIF file for LoTW. If I trying to do that, I see the message "Export finished No QSO written". Now what? If I will export ADIF file via File-Import/Export menu, will be this file compatible with LoTW?
Regards, Mike
