On August 20, 2010 at 12:11 AM CST, a garbled Russian voice was detected by amateur listeners. It made a short message with little interference and then repeated itself with noticeably more static. This followed recent activity on the station that included more static than usual and several instances of objects being moved/dropped. All of this was detected by amateur listeners and is unconfirmed at the moment.
On August 23, 2010 at 9:35 AM PST, a Russian voice was detected on UVB-76. The voice read out a single, short transmission several times before the line went dead, then returned to its normal broadcast. As the message was transmitted on upper side-band, reception with ordinary AM receivers was weak and distorted. The following recording was made at UVB-76 Internet Repeater in USB Mode (Recording of the voice transmission on 4.625MHz USB 4.5kHz bandwidth)
