Whales In Space

Something odd is up with the UVB-76 Buzzer, a mysterious 10 kW short wave radio transmitter that has been transmitting a buzzing sound at 4625 kHz since 1982 from outside Povarovo Russia.

Multiple voice transmissions and odd activity has been reported in the past several days.

The mysterious signal is speculated to be either some sort of military signal or possibly a High-frequency Doppler method for ionosphere research that would be looking for changes of an ionosphere state can be caused by solar geophysical or seismic events.

Occasionally, the internet gets all excited about the UVB-76 Buzzer when the rumor goes out that it has stopped broadcasting, as happened in June of this year, but a voice signal from the transmitter is something special, with only 4 or 5 reports of this happening since it was first detected in 1982.

The recorded vocal transmission isn’t the only odd thing to have been reported in August of 2010.
http://en.wikipedia.org/wiki/UVB-76 lists quite the activity this month.

* On August 20, 2010 at 05:11 UTC, a garbled voice speaking Russian, 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 13:35 UTC, a voice speaking in Russian was detected. 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.
o The message, repeated twice, was: UVB-76, UVB-76 — 93 882 naimina 74 14 35 74 — 9 3 8 8 2 nikolai, anna, ivan, michail, ivan, nikolai, anna, 7, 4, 1, 4, 3, 5, 7, 4[11]

* On August 24, 2010 at approximately 04:00 UTC, a heavily distorted voice was heard by amateur listeners.

* On August 24, 2010 at 13:25 UTC, another heavily distorted voice was detected by several amateur listeners.

* On August 24, 2010 at 17:43 UTC, Hard to hear voices were heard over the transmission.

* On August 24, 2010 at around 03:30 UTC, distorted voices in addition to fast beeps and pulses were heard.

* On August 25, 2010 around 06:13 UTC, Random knocks or shuffles as if someone is in the room, changes in tone randomly.

* On August 25, 2010 at 06:45 UTC, A grumble or garbled sound appeared out of nowhere for 389 ms.

* On August 25, 2010 at 06:54 UTC, Another transmission occurred. (Recording of the fifth voice transmission) A new sequence/pattern with a chirping/crank noise occured on top of the previous buzzer. At times this new noise made the old buzzing noise barely audible. The message content was: “UVB-76. UVB-76. 38, 527. Akkreciya. 36, 09, 55, 73.”.

* On August 25, 2010 at 18:07 UTC, Morse code could be heard behind the buzzer signal. It lasted until approximately 18:20 UTC. At approximately 18:08 UTC A tone was heard in the background followed by a short message.

So what is up that would spark this amazing spike of activity from the UVB-76 buzzer?
