G01 Tyrolean Music Station

Priyom G01 · Tyrolean Music Station

G01 , also known as the Tyrolean Music Station , was operated by the French external intelligence agency SDECE - Service de Documentation Extérieure et de Contre-Espionnage (External Documentation and Counter-Espionage Service), the predecessor of the DGSE . Transmissions ceased in 1975, in the few following days after the French anti-establishment magazine Interférences published the information that the station was operated by the SDECE from the area of Chartres, in France . It was quite a unique station: rather than simply broadcasting groups of numbers, it also occasionally sent messages as coded sentences - similarly to the better-known example of Radio Londres's "personal messages" to the French Resistance during WWII.

G01 transmitted every Saturday and Sunday at 11:30 UTC, simultaneously on 6425 kHz and a second frequency around 6660 kHz (several sources mention 6640, 6650, 6660, 6665 or again 6675 kHz). G01 also operated another less known schedule, possibly on Monday and Friday evenings at 18:30 UTC on lower frequencies. As its name indicates, it made extensive use of Tyrolean music and yodeling as introduction, however in an uncommon way: transmissions happened as follows.

Most of the time, the Tyrolean music introduction was made of the same three songs. Sometimes, a fourth song was also played. Sometimes, different songs from the usual ones were played instead. (These variations in songs would correspond to the G01a designator.) Sometimes, in addition to playing different songs from usual, these were interrupted by messages in the form of coded sentences - a variant known as G01b; for example: "Helmut grüßt Franz. Helmut grüßt Franz. Guten Tag! Die Größen 26 bis 32 passen mir gut. Die Sonne scheint herrlich. Unsere Henne ist dabei, ein Ei zu legen." (Helmut greets Franz. Helmut greets Franz. Hello! The sizes 26 to 32 fit me well. The sun is shining wonderfully. Our hen is about to lay an egg.) The music would be abruptly cut off at three separate intervals to switch to announcing the same series of messages each time, with the last repeat concluding with the supplementary greeting "Alles Gute! Auf Wiederhören!" (All the best! Goodbye!), before switching back to the music.
