Numbers stations, beacons and other radio sounds

[Rdrac13]

...how did i get hear from dubstep...

[poorlymadeproduction]

holy crap these are cool!

[itaRomeo]

6:55 not MFSK so JST65 HAM RADIO digital mode comunication

[s52ab]

Super !!. Signal must be have a screenshot. Your video is complete.

[iluvdx60]

REALLY LEARNED ALOT MAN. LIKE THIS CHANNEL OF YOURS. REAL GOOD!

[aurora990]

I had been listening to shortwave radio for almost 17 years and I was wondering what were these unusual noises on shortwave radio. now I know the noises heard on shortwave radio are beacons and datalink transmissions.

[DFC37]

nice compilation. DEUDK2 and DEUAT just mean "de" (from) UDK2 and UAT which are Russian naval stations. TAH is a Turkish naval station.

[jabajabamaster]

If you search on the AM-band, you'll get a lot of weird things.

[SWL1409]

Great, at 2:13, I receive very often this "TAH" beacon and others letters.

I can receive too multi-beacon at 8432 KHz SSB.

[PA5MS]

The signal on 7,0775 is WSJT, mode JT65A or JT65b this is a weaksignal mode mainly used on VHF/UHF/SHF

[PA5MS]

The 7,7705 signal is WSJT or JT65A JT65B mode. This is a weaksignal mode mainly used on VHF UHF, for example on Moonbounce or very long distance tropo contacts.

[X06Shadow]

the DEUDK2 is a SITOR-A data link for russian ships. i have lots of messages decode from that signal if u want some

[stg7]

Thanks, X06, I will check your channel, looks interesting.

[hemochromatosis]

and they say sw is dead!

[JohnnyX50]

Many thanks for the video I have also heard the DEUDK2 thing and often wondered what it is. There is still alot out there I would love to know more about. Glad Im not alone in this quest!!! :D

[m134mr]

thanks for this video. when i have been listening to SW, i notice many obscure sounds, and wish i could find out more about them. very helpful, thanks!

[malignantpoodle]

Great compilation! I'm getting a SW radio today!

[Mainsail76]

That polytone on 7077 khz has been active for years. It's pretty constant. It'd be interesting to find out what it is and where it's coming from. And no burrstyers, I don't expect that it's anything sinister. I've never lost sleep over anything let alone something I've heard on HF radio. Nice video stg7, I enjoyed it very much.

[hillbillyprofane]

I should add, the polytone station reminded me of something weird I experienced as a kid. There used to be a phone number you could dial (it was just three numbers, I believe) and you would hear a strange polytone recording. Any ideas what it could have been for?

[hillbillyprofane]

NIce collection of recordings here. For some reason, letter beacons freak me out. I can understand the idea of numbers stations, but what could a constantly-repeating Morse code letter be for? Just a marker? I dunno, freaks me out.

[marsgal42]

The rapid sweeps though the recording (e.g. 5:50, 6:43) are ionospheric chirp sounders.

[poorlymadeproduction]

i want to download the one that starts at 0:55 its fasinating and im making a flash game and that would be a great audio file to have since this game with be a bit of a horror game and there will be parts where you will be in dark isolated rooms and i thought that if your listining to that in the dark you start to thinki of what is around you but whats around you for the most part is unknown so in theorie it makes it more scary!

[heylibertine]

..what?

[frmatt07]

Hi

10360 GW datalink marker from SAB, Goeteborg, Sweden

5340 Mossad E10 KPA stn

8030 Link-11 aka TADIL-A or ALLIGATOR

7077.5 is a HAMradio mode MFSK

HF is good

[stg7]

That was an outstanding contribution. Thank you very much! Will add those notes as soon as possible.

[PunkRojo91]

como capta estos sonidos?

[Letsgoherd3008]

its not deuat its DUAT it was a dopler radar service for pilots

[burrstyers]

I used to do this stuff for a living a long while ago.

It is actually DE UAT. DE= From, UAT Soviet marine Shore station, probably up on the north coast somewhere. No mystery. Speaking with a good amount of prior knowledge, there is nothing that I have seen on here that would push the "interest" buttons of government agencies. Remember that all of these unusual sounding transmissions are made in the full knowledge that they will be (and are) intercepted by a third party. HTH

[Thetrutv]

How do you do it ? what das it look like ? can you make a video about it ?

[burrstyers]

One more time. It is DE UAT. Which is a soviet marine shore station, exactly the same as others that have been noted. Followed by a form of data transmission - similar to navtex - that also says DE UAT. There is no such mode in this world as a doppler service for pilots. Sorry that the answer is much more prosaic than you imagine. I would agree though, that the HF band still continues to have much of interest to the casual listener. 99.9% of it is benign. Sleep well.

[SupraTompan]

Thanks for putting this up,

very interesting!

[toxicwar]

again...someone explane to me what this is about... i relly want to know everything about this pleaze

^-^ email me :3

[pitcalco]

A slight, very slight correction for 1:30 and the "KPA2" station. This station is simply known as KPA and the 2 announced at the end only serves to signify that no message is to be sent at that time. If a message is to be relayed, then the message is "KPA KPA KPA KPA..." and then the alphanumeric coded message. It is the same channel.

[stg7]

Good to know! Thank you very much for pointing out :)

[commissarusa]

@pitcalco

Do you think KPA means "Korean People's Army" as in the military of North Korea?

[pitcalco]

@commissarusa Hehe, no I don't think so, but that has occurred to people as well. The Mossad also once broadcast a "CIO" station (they might still do) which some suspected as being directed to the former Rhodesian secret service, Central Intelligence Organisation.

[TheLegoboy1997]

@commissarusa KPA2 is kind of like an interval signal. These head coded messages from the Israeli intelegence agency, AKA Mossad. If I remember correctly, the 2 after KPA means that there will be no message following.

[hedandkenproductions]

mmmm...beacon

[KeLopezCL]

¿Qué son los "beacons"? Disculpa la ignorancia :/

[stg7]

A ver si me explico... Son transmisiones desde sitios conocidos que transmiten una señal continua con poca información, generalmente su indicativo o lugar. En castellano podríamos llamarlo "baliza".

Un saludo :)

[KeLopezCL]

Gracias ;)

DEUDK2

soounds like morse code ( sorry if spelled incorrectly )

[stg7]

Yes, DEUDK2 is spelled in morse code, what remains a mistery for me is what follows that spelling (the bird-like sounds, "brrip brrip brrip..."). Maybe it is just a channel marker from Murmansk, Russia, but I have not confirmed it.

[electratix]

so different countries have different sounds?

[TheOriginalDJFender]

UDK2, MURMANSK RADIO, RUSSIA

UDK2 DE UDK2 DEUDK2 DE UDK2 DE UDK2 DE UDK2

29 - 12 - 2005 10.05 UTC 16822 KHz CW CH. MARKER

[stg7]

Oh! So it was THAT. Thanks for clarifying, I will add some notes to the video :)

[burrstyers]

it is a Russian Marine shore station, callsign UDK2. The DE in morse is universally understood as "From". The noise afterwards is an example of an data mode that runs at about 45 baud (IIRC), and if you were able to interpret it it would say "DE UDK2". There is commercial software available for free that will do this. HTH and sleep well.

[uploadJ]

Nice visual showing the letters/characters ... I'll try that next time too!

[MattExzy]

8030kHz - NATO link 11 protocol! Took me a while to figure out that one....

[stg7]

Thank you very much, I will add that ASAP :)

[bl00dyscars]

asap?

[marcelomar2]

what are the numbers stations for? omg this is so fucking mysterious.

[JKH1232]

It's generally believed- and been acknowledged in a sideways manner- that numbers stations are coded messages for spies. Basically, each string of numbers is a message for an agent somewhere. Or a dummy message to make you think there's a spy.

[burrstyers]

Not mysterious. They've been going decades to my knowledge, in fact there are far less of them than there used to be. Short answer, One way communication from the government of one country, to its agents in another country. Which in one form or another has been going on for centuries. Don't lose any sleep on it.

[marcelomar2]

i know that. i mean mysterious because we dont know what these messages says.

[burrstyers]

You, me and pretty much the rest of the world will never know. The codes used are very strong. Just accept that the best brains, with the best means available will have a go a cracking these codes.

From spies that have been caught in the act, messages usually contain pretty mundane stuff - wife and kids doing fine - only another three months and then you go leave - don't forget to do a bit of spying while you are there etc etc.

[stuartthegrant]

OK very intersting.

[Amishman35]

At 8502kHz SSB in zip code 02878 there is a a signal like 2:40 that is morse "WLO".

[apolloscam]

It came from outer space...

[led022]

i heard "CBV". this signal sounds like the "TAH", with the datalink sound repeated 4 times

[yt86753098675309]

I don't care about the telecomuncation act of 1967. I will listen to what I want to listen to.

[pitcalco]

Yes, and in fact I would like someone to point to the chapter and verse making it illegal to listen to number stations, considering that they do not officially exist.

[grahamkeithtodd]

lol i know mate but here is a disterbing thought.all serverd in the uk,europe and the usa have whats called a black box fitted to them so at any time the secret services CAN and DO tape them to find out who is looking/communicating with whom..i am sorry to say but that nasty bit of tech was invented in the uk and taken up by the american NSA with glee!the internet is NOT as scurer as some people think!

[grahamkeithtodd]

you do relise that in the uk(and indeed most of europe)it's ILLEGAL to listen to these number stations?

it's covered under the "telecomuncation act of 1967"

mostly these number stations are ways to tell your spys overseas what you want of them.

usely there complaints about there officers overspending there expence accounts!

[stg7]

"you do relise that in the uk(and indeed most of europe)it's ILLEGAL to listen to these number stations?"

Yes, but as long as YouTube servers are in the United States... I don't care very much :D

[pitcalco]

I think grahamkeithtodd is simply repeating the same urban myth. It is not illegal to listen to numbers station nor can it be since no government will even admit that they exist. And as for "complaints about expense accounts", unless he was the intended recipient of these messages there is no way he could know what the messages mean.

[mitsosfantasia]

cool audio's!

[itaRomeo]

Great video!

Any mysterious trasmition on radio!

[amandalee7747]

I hear D/P/S/C often... and A/P/S/C (???)

[LCduT]

KPA2 sounds like E10 (Mossad). The other stations are a complete mystery to me.

[betomiyazaki]

la estacion en 7077.5 CW puede ser una de tipo XP (politono)

[stg7]

Muy interesante aportación, aunque llevo un tiempo siguiendo señales extrañas nunca había reparado en ese tipo de estaciones :) Intentaré buscar más sobre esa clase de emisoras.
