Thank you, Ed, but that didn’t work.
+ If your log contained a QSO with no callsign specified, the BROKE filter would have identified it.
+ The problem is not that you are submitting a QSO with a missing callsign, it's that you are submitting a QSO that has already been submitted. The diagnostic task is to determine why that's happening.
+ The most common cause of this situation? You have one or more duplicate QSOs in your log, possibly from importing a file of QSOs that you had already imported. But let's not jump to conclusions; please filter the Log Page Display to show all QSOs with AA2IL. Is there more than one copy of your QSO on 20m CW on 2022-06-14 at 03:23:24Z ?
