A similar voice message was broadcast on September 12, 2002, but with extreme distortion (possibly as a result of the source being too close to the microphone head) that rendered comprehension very difficult. This second voice broadcast has been partially translated as "UVB-76, UVB-76. 62691 Izafet 3693 8270."
Interesting coincidence (or maybe not?) that the layout of the messages are the same
