The QSL card from the Kronbühl radio station features a stunning aerial view of the surrounding landscape, which highlights the scenic Lake of Constance and the nearby city of Friedrichshafen, located 12 km away. Prominently displayed are the call sign HB9 KNY and the Swiss flag, representing the station's location in Switzerland.

The details include equipment specifications and a note of appreciation for the contact, which contributes to the sender's pursuit of a new DXCC. The card is signed by Christian Eigenmann, providing personal touches along with operational details.
