At this webpage you can validate, whether you are represented in one of my logbooks. All logbooks are searchable, also those of activities within Germany as well as those of DXpeditionen. However, please pay attention to the notes for logbooks.
If you would like to receive a QSL card as confirmation for a QSO, you should send me a QSL card via bureau (preferred) or directly (SAE only). SWL reports are always welcome.
