and big welcome to our D-Star Repeater DM0WM located in the beautiful city of Karlsruhe. The repeater is housed directly on top of the roof of the University of Applied Sciences building.  We are operating on 2m (C-band) and 70cm (B-band) and also connected to both D-Star servers. The repeater is also involved in a student research project which researches the digital radio network, communication and the pro and contra features regarding to the electrical wave propagation reflection attributes.
