Swedish Rhapsody (numbers station)

Swedish Rhapsody is a well known numbers station, operated by the Służba Bezpieczeństwa (Later Agencja Wywiadu) that used AM broadcasting and operated between the late 1950s and 1998. It is notorious for its use of what was once believed to be the voice of a young girl speaking in German, yet it was later revealed to be that of a special machine used by the German Stasi known as the "Sprach-Morse-Generator".
The numbers station is mostly known for its signature melody, Swedish Rhapsody No. 1 by Hugo Alfvén, recorded from a music box manufactured by Reuge, although Agencja Wywiadu claimed that the melody is the "Luxembourg Polka".
After the dissolution of the Soviet Union the station ceased operations, yet it is believed to have resumed broadcasts using numbers in the English language between 1998 and 2003, under the now NATO ally Polish state.
