Welcome on my liddle homepage!
This is Roland Hartmann, an amateur radio operator. My callsign is DK4RH.
On this page you can find a litte bit about my home location, links to QRZ and Clublog with my used callsign-extensions, some of my Awards with quite nice picts and an access to callbook of hamlog where it is possible to search for your callsign.
In addition the 'Maustag' - a day with events for kids in Germany where we take part as local ham-radio club and last logs from the Mondays 'Nachteulenrunde'. Both written in German.
