+ AA6YQ comments below
do you use the QSO Logged UDP message or the Logged ADIF UDP message to capture logged QSOs?
+ "Logged ADIF" (MessageType 12)
Do you have Tab 1 messages enabled in WSJT-X?
+ I am using the TX messages on Tab 1, which do include my class and section.
+ If there's a "Tab 1 messages enabled" checkbox, I'm not aware of its location in the application, and see no reference to it in the "2.2 User's Guide".
