Russian Radio Signal UVB-76 has stopped transmitting.. UH-OH

Definetly still brodcasting

07.013.00 on Hamspehere if want to hear for self .

somebody earlier in the thread had the idea that was some form of comunication to the russian neuclear sub fleet a new class ove neuclear subs come into operation this year could this be a transition period for the signal? still its strangely reasuring it aparantly still broadcasting considering i had forgoten about this transmission for years! now i am really interested about it again

I think the recesses are sewage(less likely) / cooling ponds( quite possible)?
these would tie in with the lake to the south and wouldprovide cooling water to air conditioning and warm areas eg computer rooms and general cooling

they could even have been bases to satellite dishes?

The electricity substation is also fairly large( to the north west) much larger it seems to me than the low density housing would seem too need

The roadways could just be firebreaks( as in woods catching fire ) or security fire breaks , maybe trees where kept short in the old soviet days,for keeping watchtowers clear line of sight


However the layout radiating from the buildings , could have been for the multiple ultra low frequency ariels used for communicating with submarines , the British version of this had the same basic ariel layout of multiple stringed ariels , with a better image perhaps the concrete bases for the ariels may be visible?

After reading that Russian page from 2004 about the station, it appears that it is used by the military for the enlistment offices. (Theirs probably works different than our enlistment in terms of what it is they are responsible for.) The acting duty officer receives information via morse code. If the communication lines are down, the station begins broadcasting into the duty office with instructions in lieu of the morse code. I can only guess that the duty officer does not hear the buzz unless the morse code communication circuit is dead, at which point the buzz is heard. They are instructed to push a button whenever this happens.

The duty officer, apparently, has a one time use card that they use to match numbers/names to in order to receive their instructions.

The photos of the trees down are likely communication lines for the telegraph system.

Why not digital? Because the Russians have a history of "if it ain't broke, don't fix it, because we ain't got the money." And it's also a simple system that can likely be repaired quickly due to war damage.

Anyway, seems like everyone agrees that this is what it's used for. Half the people responding were from various enlistment offices and were aware of the buzzer sound, and what they were instructed to do when they heard it.

Do you know of a better site to listen to? A 10 second loop is all you get on that site. A streaming site would be nice. Any one know of one?

Ask, an you shall Receive!

uk3-pn.mixstream.net...

My icom IC-R20 hooked up with untuned 5m grounded whip. Located about 900km NW from the station (Tallinn, Estonia).

The receiver is tuned on 4625MHz, AM modulation. The RTTY signals in background seem to be from 4623.60kHz LSB. No idea, if ithey are somehow related or not. However, time-to-time there is a clear morse code reception on the 4625MHz with heavy dopler shift at the end -- exactly as the satellite transmission, except on low end of shortwave?!?!

The receiver is in timezone GMT+2 and shortwave propagation does not allow reception earlier than somewhere 6pm local time, so do not expect to hear anything before 4pm GMT. If I have nothing else to do with my scanner, I will keep it hooked up, but if you do not hear static from the channel, then I have probably taken it down.

Let's hope it's not a copyrighted material I am re-transmitting! ))

Andrus.

That link has been fun to listen to.

Noted something odd though at 23:47 British Time. At least four of the buzzer noises were missing from the transmission. I do not know if this is significant or not, but I thought I would mention it! As I was about to post, at 23:49 i had what i can only describe as a door opening or shutting very faintly in the background

Yeah I knew about them. But if there was another transmission right after it supposedly went off the air then THAT is the monumental part.

and that stream... thanks. It sounds like you're near a high way.

Woah... random solid bass note... Continuos and over powering the buzzer. Can't hear buzzer any more and I am hearing voices...

I can also hear voices...

Sounds like a slight freak of nature, and the voices are some local civilian radio station in estonia (where the link is from)

The radio station and low-pitch hum at the moment is definitely coming from 4625 MHz frequency, but it seems that it is just breaking in from other parts of the world (cant recognize anything, but sounds like spanish. Definitely not estonian). Quite logical, as it is couple of hours from sunset here now and shortwave band gets garbagled with all sorts of reflections, near and far.

Signal should be clearing up in about 10pm GMT.

Andrus.

Well I heard voices, and thought it might have been estonian - a logical assumption i thought.

Oddly enough though, I've been able to pick up the buzzer all through the day - even though you said it would be filled with static. At 12:00, 13:30 and 15:00 it seemed to miss a buzz out as if something had caused it to go silent for a moment.

Wikipedia had an entry in the Malfunctions section of the UVB-76 page, and it stated that it went off line for no reason. Several hours later the remark was removed. Now the page says its for a research project - but it wasn't saying that before this morning.

The radio station and low-pitch hum at the moment is definitely coming from 4.625 MHz frequency, but it seems that it is just breaking in from other parts of the world (cant recognize anything, but sounds like spanish. Definitely not estonian). Quite logical, as it is couple of hours from sunset here now and shortwave band gets garbagled with all sorts of reflections, near and far.

Solved it. The radio station breaking in is Radio Sweden International transmitting on 9360kHz from Stockholm at 125 deg. So what is breaking in is actually second lower harmonics (4680kHz) of that station.

No can do about ..

Andrus.

Thanks for clearing that up.

To clear it up, have you tried (assuming you set up can do this) enter the frequency manually instead of an automatic scan? I've heard this might clear up the problem, but I'm no Ham radio opperator.

Do you listen to it all the times you arn't using it for other reasons? I was wondering what other Number Stations you can pick up on your set... I'm fasinated by them

Icom R-20 is quite decent scanner and I am able to enter the frequency manually (what you do for shortwave bands anyway, as they are so crowded with all sorts of signals, useful and not, that automatic scanning hardly makes any sense).

However, as my little internet radio project seems to have magnitude more fans than I was expecting (2383 hits from 39 countries in one week), I have also spent a magnitude of more time on it as I originally expected
Therefore, since last night, the listening post is equipped with nice 145cm diameter resonant magnetic dipole I have just built! As this antenna is tuned exactly to the correct frequency, the signal has now much less noise than initially. The antenna is also very directional, so I hopefully it will "hear" less commercial radio.

If I can figure out a way posting pictures to the forum, I could send some photos how it looks over here

Last few days have been with poor propagation conditions, tonight is much better. I have my scanner at the moment hooked up 24/7 the live stream, but I am building a small dedicated receiver, so if it turns out good enough, the stream gets its own receiver and icom can be used for other projects!

Regards,

Andrus.

Bahahaha. Hamsphere isn't actually radio. It's like a voice chat with only online capabilities.

Ah . . . That is much better now! Thank you very much for that.

What other number/voice stations can you pick up?

Sorry for another post, but I've lost the editing feature...

At 16:32 GMT the signal was abruptly cut off mid buzz. It had been sounding very odd for the previous half an hour. Just as the signal vanished, there was a sound heard which I can only decribe as being like the noise you make when you knock into an object

EDIT: Resumed buzzing at 16:38 GMT

I still love this thread!


Did you hear anyone yelling "Blackjack" in Russian in the background?

reply to post by Signals


Nope, I didnt hear anything othern then hat I said.

What is Blackjack anyhow?
