Hi Patrick, ON6AT
Why not use the SQL Query Filters in the Adv panel ?
Caption: UBA Pfx
SQL expression: (FREQ BETWEEN 29 and 1.8) and (QSO_Begin BETWEEN #2020/06/01# and #2020/07/01#)and (Station_Callsign like 'ON6AT') and not(Call like '!*')
Click on Filter and all your QSO's are in the filter
Then go to the Panel "Export QSO's" in the next window press "No" in our case "Nee" click on Export ADIF for Club Log then Start and now type ON6AT-06 and "Save" in our case "Opslaan".
And that's all.
This is the way I do , and my log is always accepted.
PS: do not forget to save your SQL Query Filters
Hope this will help
