The US occupation authorities established the broadcaster Rundfunk im amerikanischen Sektor (Broadcast in the American Sector or RIAS) just after World War II to provide the German population in and around Berlin with news and political information. By the end of the Cold War, the broadcaster’s importance faded away and by the early 1990’s other German broadcasters absorbed its broadcasting facilities.

I heard them on FM during a trip to Berlin in 1987.  Their medium wave (AM) outlets were all easily audible at our home in southern Germany.  I also heard them on shortwave in the USA on 6005 kHz. They responded with QSL cards, which can be seen below, for my reception reports.
