G02 – Swedish Rhapsody

G02 was one of the more prolific numbers stations. It had a stable schedule for its time and rarely ever had any errors in transmissions. G02 was also one of the few stations that never sent a group count, but always sent 100 groups to each agent identified. In the 1990’s it was replaced by a variant called G02a.

Despite being named after the song “Swedish Rhapsody”, this is incorrect and was misidentified for a long time.  The station’s actual song was shown in declassified documents as “Luxemburg Polka” composed by E. Reissdorf.

G02 was first observed in the 1960’s, but could have been running earlier since the 1950’s.  Over it’s lifetime it was first operated by the Polish State Security (SB), then the Office for State Protection (UOP).  It was last heard on April 9th, 1998 and was replaced by E23.  Though E23 had a similar voice to E05, they were not related.

Recording Sample

G02’s voice was generated using the Stasi Sprach Machine, but usually manipulated to sound much higher than typically heard. If listened to closely, certain characteristics of this machine can be heard (such as the hard R in ‘drei’). Because of the pitch, to some, this station’s voice can sound like a little girl’s, and to others an adult woman.

The triple message format of G02 has 2 additional messages and headers to those messages. The third message is also 50 groups long instead of 100. G02a differed in the way where there was a header (“12345 67890 12345 67890” 2x) in between the interval music.

Originally, G02 had always sent three messages together, but in 1988 it started sending one 100 group messages, and sometimes two.
