DISCLAIMER

DISCLAIMER: I have no association with UVB-76 station, neither do I have any clue what is the content I am relaying. I can only assure, that the signal is received on 4.625MHz AM-modulated 900km NW from supposed origin and retransmitted unaltered. In no way can I guarantee this service, nor be considered responsible of any content re-transmitted. The only purpose for this relay to exist is because lot of people who do not have equipment or are located too far from station seem to be interested about listening to it. Should the UVB-76 station- or transmission content owners feel violated in any way, please contact me at uvb76.repeater@gmail.com and we will work it out.

Note, that because of shortwave radio signal propagation specifics the station can be more or less reliably received from around 4pm to 6am GMT on summertime. It is almost 24h audible during the winter, with short "skip-zone" blank-out around 6pm GMT.

The USB feed is considered as main source of audio today, as the voice messages are much better audible there than on the AM stream. However, the buzzer sound from the AM stream is somewhat more pleasant to listen at, so both feeds are kept simultaneously.

August 25, 2010 6.54UTC Voice transmission confirmed

Took a while to exec through the list of all supposed transmissions:
I do have reported transmissons from August 16 and 17 what I am unable to confirm, as I do not have recordings between August 15 and 18.
August 23 was OK and has already been confirmed.
August 24 has three reports for 12:00am EST, 9:25am EST and 12:43pm CST. My search on a recordings does not confirm these three, except that 12:43pm CST is likely a commercial radio station breaking in.
August 25 I have three different reported transmissions: 2:45am EST, 6:54 UTC and 11:53 UTC.
Apparently, all three were the same, happening in real life around 6.50 UTC.
Please find the full recording here.
It is the same transmission, last part of which has already been circling around. It matches perfectly both, the text and static noise spikes, so it has come off from same USB stream at the same time.
August 29 has a report of buzzing stopping briefly around 16:31 UTC, but recording does not confirm that.
August 30 has a report of mumbling voices on background, but once again, stream recording does not confirm that.

  1. 3:14 am US Eastern Time on August 31st, there was a voice broadcast. In fact I'm listening to it now, with no way to record it. Definitely Russian, a bunch of words obviously meant to represent letters (like echo, tango, etc would in US military lingo). Interesting stuff.

  2. The recent uptake in broadcasts scares me, even though not all are confirmed even the confirmed ones arent sparse in the last few weeks.

    Im going to assume you had heard intermittent cuts in the beep, i did send the blog owner an email about this, expect more information soon!

    Does anyone else have recorded times or recordings of transmissions on the 29th or 30th or 31st?

    Right, that was beeps. I can upload my recording, but I wait to the answer. It's 20 seconds of beeping.

  7. I can confirm this as well. Male voice Russian numbers 1-5 then 1-3 then 1-2. Then some kind of data burst transmission. My recording is about 3 minutes total.

  9. Someone from our small "observation group" (not really, just guys hanging out in a tinychat) sent in a recording of it to the blog's owner. Can confirm the time as 6:30PM UTC+1

    It is indeed on the repeaters end, not UVB-76.
    @swler007
    You should upload the file, and cite it on wikipedia.

  14. @ Matt. I don't really think it was sent by UVB 76. Anyway, for those interested. http://www.mediafire.com/download.php?29fz7hz4u312fxi

  15. Noticing static bursts. (1:12 CDT) Recording, anyone else getting this?

    I agree with you, that doesnt sound like UVB-76, even though it is nearly the same voice, the buzzing usually stops for UVB-76's transmissions.

    ReplyDelete
  17. The voice itself sounds right on frequency. But why would you transmit on a freq that is obviously occupied with an AM carrier.

    ReplyDelete
  18. Im not so sure it is on freq though, it sounds slightly below freq, no? I'll run it through my spectrogram

  19. @ Matt. Do it and see what you come up with. :)

    Didn't sound like the other interferences I heard so far, the interferences are usually pretty silent and you can't really understand what they say. Anyway, Youtube'd it.

    Red - Voice transmissions
    Blue - Unidentified blips (sounds like a water drop, is this happening on the computer? sounds like it)
    Green - Morse code..?

    Voice 4 is the recording of the August 23 voice, while there is no beeping, and the voice is more present, you can see how it spreads better over the whole frequency charts, leading me to believe that the other ones are *not* on frequency.
