Kasseburg, a very small rural village, is located east of Hamburg and about 9 kilometers northwest of a city named Schwarzenbek. Just near the highway to Berlin (A24) and the main road to Kiel (B404). You will find this location in a good roadmap. Kasseburg, first mentioned in the year 1230 (!) has about 550 inhabitants (and 1 radio amateur ...) . Up to 1980 my old callsign was DC4NH (UHF/VHF only). By the way: QSL 100% sure. QRV also mobile and sometimes on 'Echolink' as well.
