I understand that QTH Profiles are mainly used for filtering, but what's the reasoning behind requiring a valid locator for QTH profiles? As far as I can see, there is no way to export locator/qth/rig to files like ADI. It also does not seem to set "my_loc" (not sure what even sets that particular field)

I am also having a problem filtering on QTH profile. You must explicitly clear the filter before selecting a QTH profile for it to work properly. I would expect that clearing the dialog would not be required since the dialog pops up in a cleared state initially (actually it would be better ff it remembered the last values, otherwise what's the point of a clear button). Another issue is that Shift-F12 should results in the same QSO list as clear filter / okay.

Thanks
