Tyrolean Music Station was a vintage numbers station reported around the 1970's. It was as if disguised as a music station playing several yodeling songs with embedded messages for "Helmut" and "Franz"(at least in this recording). Secret messages found in the broadcast are introduced by several notes from a music-box rendition of the socialist anthem, "The Internationale".
As with most numbers stations its origins are uncertain but this operation was believed to be tied in to the USSR sponsored East German government, DDR - Deutsche Demokratische Republik specifically by the Ministry of State Security; a secret police agency commonly known as the 'Stasi'.
Notes:
The announcer's French accent lingering around his German broadcast has garnered questions about the origin of the Tyrolean numbers station but basic information still hold that the announcer might have been French but was working for the DDR/GDR.
