If you have dreamed of your own radio for surfing the signals out there, please check this - finally got my radio to manufacturing and now selling some :)
The talkshow goes on! Stream listeners Jeffrey and Cythelol reported what seems to be the first recorded "background voices" transmision. As both reports were submitting a recording as well, the attached clip by Cythelol can be found here. I will replace it with the one from stream archives when I have identified it! The voices start at about 20 sec. PLEASE DO NOT LINK OR DISTRIBUTE THIS FILE, as it has windows sounds at the beginning and although it has been confirmed by two independent sources, I would not let anything to corculation what has not come off the streamer recording archive!
Also, please be prepared for a short 1-minute break in streaming tonight, as I have to re-start the system to get rid of the 'scattering' artifact.
[EDIT: The scattering has actually had an effect on archive recordings as well, so the one recorded by Cythelol is actually of better quality than mine. I can, however, confirm that the transmission is genuine, as it is present in archive recording and received in USB mode - if it would not have originated from the same frequency, the audio would have had serious pitch shift.]
There is another voice reported on 12:45UTC, but I havent been able to locate it from archive yet.
What about the the file that I posted that DEFINITELY had voices heard in the background.
ReplyDeletehttp://customtechnologiesnh.com/uvb-76/uvb76-voices.mp3
Take a listen. There is certainly something happening, and it is not from another transmitter as the voices fade with the buzzer fading as well.
@DeadlyFoze
ReplyDeleteYou picked up a german station that is on a different frequency, if you listen close enough this type of thing can be heard frequently.
Sorry for dissapointing you, but this clip has a characteristic recording of powerful commercial radio stations breaking in at around sunset..
ReplyDeleteIm listening right now, background voices.
ReplyDeleteyou have done a hell of a job with your blog sir,
ReplyDeleteI commend you for just wonderful work.
@ Derek
ReplyDeleteThats interference from a commercial station. However i had short one to two second bursts of static (4:03 CDT), probably something to do with propagation but ill check into it.
@ Matthew
+1, I agree.
3 morse at about 11:20-25 pm CEST
ReplyDeletejust happened
recorded "most" of the second
someone else got the full third
fourth happening now
I think I recorded the first morse transmission:
ReplyDeletehttp://dl.dropbox.com/u/154184/uvb-76k.mp3
There's a new one right now, recording this too.
I just heard what sounded like morse code briefly at 9:27 PM UTC. Can anyone else confirm this? The buzz tone did not stop, and the transmission only lasted for a few seconds.
ReplyDeleteyeah four morse codes where sent
ReplyDeleteatleast thats what i heard
between 11:20-25pm CEST
@ DeleteAndRepeat
ReplyDeleteI have it too (the full thing), though i'm pretty sure its (again) just channel bleed.
Here is the recording.
http://www.mediafire.com/?1nzw00y1w4rchxx
@ Mat
ReplyDeletedoesn't sound like channel bleed, someone trys to decode them later I think
Mat: I can confirm this, here's my recording of the second transmission (I think it's the 2nd, but I'm not sure):
ReplyDeletehttp://dl.dropbox.com/u/154184/uvb_76l.ogg
@ DeleteAndRepeat
ReplyDeleteHere is an excerpt from an email i got from the owner of this blog
It is actually quite easy to see from WinradHD screen, if it is part of the signal or separate bleed-in:
(one listed item that did bleed into the channel)
- Morse tranismission at 4627.3kHz
Attached was a picture of the Morse code, it looks very similar, but i'll email him back with the morse code to double check.
someone tried to decode the morse
ReplyDeleteresult:
Q T E V J6 RJDIEEHE RJP99 RJP99 TNTSA
he called this the most uncorrupted part
anyway I'm gone for today
I tried to translate the morse, these are the best results I got so far:
ReplyDelete6 RJDIEEHE RJP99 REOP99 TNTSATI6TNEETEE MONT EEEA? Q T E V J6 RJDIEEHE RJP99 RJP99 TNTSATE 6TNEEE TEE MMTMTET EEEA? Q T E V
E's and T's are mostly erroneous charachters, but RJP99 is definitely a callsign, but I can't find out which one.
Find on this page "RJP99". There is some information about russian navy. But I do not understand the text...
ReplyDeletehttp://www.cvni.net/radio/nsnl/nsnl144/nsnl144mil.html
(from google)
Guys, it is possible for other people to use the frequency. i wouldn't read anything in to the morse code unless the buzzer stopped and started around it. if the buzzer is coming in clear and the morse is broken up, it's not coming from the station. the link containing uvb_76l.ogg is NOT morse coming from UVB-76, it's coming from a separate transmitter. i don't have time to review the rest but those of you that have heard all of the recordings should be able to extrapolate from what i've just said.
ReplyDeleteGenewitch is right. I revise my answer, after talking to Laid i can assume it isnt channel bleed, but actually transmitted on the same channel.
ReplyDeleteNot sure where it came from though. (again agreeing with Genewitch) it probably isnt coming from the UVB-76 station.
Can anyone clarify what these hisses/bursts of static are?
ReplyDeletehttp://www.mediafire.com/?ui7j2rjaxt76cjc
(seen on Aug 31st 18:47 CDT)
They had been repeating every couple of minutes for the past half an hour, almost drowning out the intermittent buzzing.
Mat,
ReplyDeleteRef the Morse on your recording.
http://www.mediafire.com/?1nzw00y1w4rchxx
It reads
'VVV
RJD56 DE RJP99 QSA IMI QTC K'
Russian Navy fixed call RJP99 calling up RJD56 - asking for a signal strength check and offering a message.
This is quite clearly adjacent traffic off frequency and not associated with UVB-76.
http://www.astrosol.ch/networksofthecisforces/navymorsenetworks/5379039b980e47704/index.html
Interesting, but the question is, why would they broadcast on the same signal as UVB-76, they ought to know that the channel is being used.
ReplyDeleteAnyway, still unsure about the static bursts as posted two comments above, anyone?
August 31st, 8:13 EST - Just heard what sounded like a morse code, and I have no recorder. I hear it again as I'm posting this comment.
ReplyDeleteMat,
ReplyDeleteThey are not broadcasting on the same signal. The Morse had been measured properly on CW and is up at 4627.3 on CW. (Continuous Wave). Other Navy associated Morse has been recorded by radio enthusiasts down at 4619.5 on CW.
There are several other Russian broadcasts that follow the same format as UVB-76 in its codeword traffic. One Morse station is REA4. It transmits on a number of frequencies to reflect the propagation conditions. It maintains the frequencies in use with a carrier using revolutions. (A constant purring noise). It too sends the same format codewords as UBV-76 although it uses Morse. The carrier stops - the codeword is sent - the carrier is then switched back on to maintain the frequency.
The static bursts are actually a data transmission taking place lower the UVB-76 signal and therefore is audible in AM mode on lower sideband. There is a blog entry about this togethed with picture, how it looks on WinradHD screen: http://uvb-76.blogspot.com/2010/08/data-bursts-near-uvb-76-frequency.html
ReplyDeleteThe clue is in the format of the codeword traffic sent by UVB-76. It reflect its status as a command and control broadcast. The low frequency also dictates its intended area of propagation in the Moscow Defence District.
ReplyDeleteUVB-76 93 882 NAIMINA 74 14 35 74
Example of Morse codeword traffic on other Russian Military broadcasts and networks.
RCV 43243 SHOLAST 5301 3473
REA4 01293 BALANVA 1958 4088
RDL 82024 75205 BROMNYJ 1346 1872
http://www.cvni.net/radio/nsnl/nsnl133/nsnl133mil.html
http://www.cvni.net/radio/nsnl/nsnl129/nsnl129mil.html
http://www.cvni.net/radio/nsnl/nsnl105/nsnl105mil.html
As you can see the frequency range covers all the HF frequency band from 3-30 mhz and also into the LF bands. Note the VLF transmissions in order to broadcast to submerged submarines the same formatted codeword traffic.
Thanks for putting this up. It's a nice spooky riddle to try and unravel. Picked up some background chatter earlier (approx 9:05pm central time). Been recording since 9:10pm. Maybe something interesting will happen.
ReplyDeleteOh, and is the fading in and out normal for SW? I had a small receiver when I was a kid and that used to happen a lot.
ReplyDeleteAnyone else hear the buzzer at short bursts and then stop?? Very odd!
ReplyDeleteI am counting around 50 short bursts of buzzing...it'll will go quiet for a couple minutes and then more short bursts. I know this is not interference or poor propagation. It's rather evenly timed, reminds me of if the buzzer was a metronome. Is anyone else hearing this?
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteIt keeps going on, the intervals keep getting longer, approx 21:30PST, 04:30UTC
ReplyDeleteNow it's just making rather odd noises, my apologies for all the posts...just don't know what exactly is going on. The new noises I am hearing are bursts of a weird noise...highly distorted. approx 21:40PST, 04:40UTC.
ReplyDeleteNow there is a siren type noise! It was a whooping noise and then a short beep followed by a rather long beep or honk. WEIRD ACTIVITY GOING ON RIGHT NOW!
ReplyDeleteJust got back from the bar, thanks for the explanation, TJ and Laid.
ReplyDelete@TillamokKeeper_0
I cant hear anything, did you record anything?
I do not have a recording program at the moment, keep listening, something is bound to happen.
ReplyDeleteI'll set up a recording session.
ReplyDeleteFor future references, just use audacity and record through stereomix.
Though Im not sure if anything will happen, this sounds like normal propagation.
Alright, I am terribly sorry I could not get a recording, I will get audacity and if anything like this happens again I will record it.
ReplyDeleteYou said there was a siren noise? Can you document at what time? I think Laid is recording 24/7.
ReplyDeleteAround 21:40PST.
ReplyDeleteInteresting. Did it sound like this?
ReplyDeletehttp://www.mdn.fm/files/194442_u6qfv/UVB-76_Aug.25.2010_6.54amUTC.mp3
It had the same type of blips once in a while, but the siren was more like a warning alarm, or something like that.
ReplyDeleteOkay, so it did sounds significantly different? Meaning it wouldnt be propagation and actually something coming from the source.
ReplyDeleteIt did indeed not sound like propagation. I cant tell if the siren was coming from the source as it was rather faint but loud and clear enough to tell it was a siren. I was on globaltuners.com as well, tuning up and down, switching from am, usb, and lsb and it seemed to come in clear only at 4.625mHz.
ReplyDeleteGot morse code. Fantastic quality Will upload, asap.
ReplyDeleteI just morse code too. Still happening.
ReplyDeleteAlright. I'm going to keep listening to see if I hear anything, I just got audacity so I will record anything odd I hear and send it to you.
ReplyDeleteMorse Code one recorded at 00:32 CDT
ReplyDeleteAudio File
http://www.mediafire.com/?wws4iokrv2x8h5l
Morse Code two (possibly the same stream) At 00:34 CDT Couldnt record on time, but i have a picture of the spectrogram, hopefully that should work for figuring out the message :)
http://omploader.org/vNWVscg/morse2.jpg
I started recording at 10:27pm (PST -7:00) and I'll probably keep recording until 9am.
ReplyDeleteOkay right now I am putting the file through a music editing program I have, I am going to slow it down and copy the morse code down and let you know what the message is.
ReplyDeleteKarl, do you have a record of the sirens?
ReplyDeleteI caught second morse.
ReplyDeleteno
ReplyDeleteCan you upload the second morse in audio? I have it on picture, but it would be nice to match it. Hopefully Laid or someone else can translate this!
ReplyDelete@TillamookKEEPER_0 Can you also translate the picture of the second morse code? (or if Karl gets it on audio i suppose that will work as well)
ReplyDeleteI'll upload it soon.
ReplyDeleteHere's morse code 1 and 2.
ReplyDeletehttp://www.megaupload .com/?d=BXS1LJ4H
Cool, I cant translate morse, but im sure someone will come online eventually that can.
ReplyDeleteI cant get the upload, it shows a non existing link.
ReplyDeleteI heard a few long beeping sounds.
ReplyDeleteNevermind, didn't notice the space, will get it and translate it. Will get back to you as soon as I have it translated.
ReplyDeleteKarl
ReplyDeleteCan you upload those beeping sounds?
Sure
ReplyDeleteat about 33s you can hear it best.
ReplyDeletehttp://www.megaupload .com/?d=W5RABUFR
Folks I now have the morse code translated. It reads:
ReplyDeleteRJD 51
RJD 51
RJP 99
RJP 99
QSA 3
QSA 3
My previous message is slightly inaccurate...
ReplyDelete"RJD56 RJD56
RJP99 RJP99
QSA 3 QSA 3"
...is what it says.
I know nothing about morse code conversations, but I did take up learning the code a while ago. Hope someone can clarify what is being said.
"QSA 3"
ReplyDeleteQSA is a Q code meaning "What is the strangth of your signal", and it's scaled from 1 to 5, meaning the guys sending the morse had a mediocre signal quality when receiving.
Mat,
ReplyDeleteNo problem.
TillamookKEEPER,
The Buzzer signal follows a pattern and runs through a cycle.
http://www.brogers.dsl.pipex.com/page5.html
http://en.wikipedia.org/wiki/UVB-76#cite_note-Mystery_Signals-5
People need to understand that when recording on AM or USB there are going to be adjacent signals audible. That includes Morse, commercial radio stations and other data signals. It all depends on the radio propagation at the time
On some of the recent broadcasts I have heard SITOR (Simplex Teletype Over Radio) signals with the Buzzer still active. Yet again
another adjacent signal and nothing to do with UVB-76.
http://en.wikipedia.org/wiki/SITOR
I understand that most of the time it's just interference and I know that the morse is not coming from uvb-76.
ReplyDeleteIt's still interesting to know what the morse means.
Join us on: http://tinychat.com/uvb-76
ReplyDeleteTJ
ReplyDeleteIs that morse not on the same frequency?
Well most of the time the morse is on a different frequency but I don't know about today.
ReplyDeletehouk.
ReplyDeleteAt 22:14 GMT, morse code transmission is present ATM on USB. Recording....
Mat,
ReplyDeleteIf the recordings were on CW and the signal tuned in correctly then it would be up near 4627khz. See previous posts. The only reason why you hear the Morse and other signals is because of the AM or USB recording mode. Any adjacent signal is going to be audible.
The Morse is simply an outstation frequency of a Navy net. The control transmits on another frequency and all we hear is the outstations working.
