Deutschlandfunk is a German public broadcasting network which specializes in current affairs and news. They have an extensive network of FM stations throughout the country and several MW (AM) stations. They have broadcast on longwave and shortwave in the past, but these outlets have closed down.
They were an easy catch on MW when we lived in Southern Germany. I sent a report of their shortwave outlet for which they returned a QSL card. They also sent QSLs for two longwave, five medium wave, and one FM outlets. I recently heard their 1422 outlet here in Maryland for which they verified my reception report.
