G02 was operated by Polish State Security of the Ministry of Interior (SB). This was the original Swedish Rhapsody, which started in late 1950s and was replaced by G02a around 1988. Swedish Rhapsody is one of the most frequently mentioned examples of a number station in media.

  Three 5-figure message headers First header Fixed-length message of 100 5-figure paired groups, with an extended pause every five   Second header Fixed-length message of 100 5-figure paired groups, with an extended pause every five   Third header Fixed-length message of 50 5-figure paired groups, with an extended pause every five  
Repeated for 5 minutes Repeated three times

The three messages could have been for up to three different recipients. The headers contain encrypted information about the decryption of the messages. If one of the messages was longer than 100 groups, then it would extend into the other ones.

Contrary to a popular belief, this station never used a child's voice. The mistake comes from the fact that many people have only heard a mistuned recording of the station from The Conet Project. The audio sample featured on this page is correctly tuned. The voice used standard German military radio pronuncations of 2, 5 and 9, being rendered as "zwo", "fünnef" and "neungen", respectively. Two other voices were also noted, one of them being the same G06 and G08.

G02 was noted for its stability, for no mistakes and usage of the same schedule over the years. Once in June 1990, it was noted with an oddity. The first five minutes of each message consisted of groups "46464" and "64646", alternating. "46464646" is a numeric equivalent of the RTTY idler string "RYRYRYRY".

According to a declassified Polish State Security document, the piece of music used for the intro is "Luxembourg Polka" by Emile Reissdorf, the portion of which is used on G02 is identical to "Swedish Rhapsody No. 1" by Hugo Alfvén.
