I was trying to achieve DX100, but I found that even after successful FT8 contacts, the other person might not upload logs, making it impossible to record them as valid contacts.
However, in the JTDX software, DXCCs that have already been recorded will not be re-marked as new DXCCs. What is the way to remove these unconfirmed QSOs and allow JTDX to re-mark them as new DXCCs?
