Weird Signal Intercepted On 20 Oct 2008

[josiejessie1]

marula TTY

[zevdwg]

Sounds like a SSTV, try decoding with MMSSTV

[pesoen]

was it on am or fm?? if it was on am it could be mencoded military signal.. if it was fm its a maitanance signal used by most radio stations..

[Born2009999]

aliens

[Antiplastikmatt]

I tried backmasking it and it said "stop listening to justin bieber and get a job". ; D

[Siemianowicee]

Sounds like Status Quo !

[willlisawsom]

sounds alot like a dial up connection

[winobint]

I remember hearing the same tone quite a few years ago now (before digital radio) when a new radio station was being set up. The signal consisted first of about 5 minutes of birdsong (like someone had made a tape recording of a park or a field somewhere), then that faded out and this signal would broadcast. The whole thing would repeat after a woman's voice said something I can't remember, followed by 'start test' or something. It's nothing sinister, probably just a maintenance signal. :)

[fighterpiolt1992]

sounds like tone dialing

[Conflagration2100]

6.344 WLO MARINE (COAST) CW BEACON (WAS WLO2) (MOBILE, ALABAMA, USA) @ Intercept Radio, the frequency variation may be due to the distance and multi bounce propagation effects.

[JeremyMcCracken]

It sounds like Slow-Scan Television

[jitjpie]

DUDE i don't know what the classification of this is , but in my recent shortwave scannings i have run into several of these. i even hit a morse code one at 6318 khz, it translated to "WLO" then a sound of a phone ringing, then repeats several thousand times. about 1 time a week it will go Beep-beep-beep-beep for a few hours, then silence... check it out!

[rencindy69]

its a AOL connetion or some ETMB or somthing idk its Earth to moon bounceing... thats what it is

[wannawatchu66]

Sounds to me like data too. Maybe a station doing some testing?

[Iesoustwist]

Has to be Jesus, see I told you he'd come back.

[livelobster123]

WAIT A MINUTE HERE.... This video was posted on October 19, 2008. Yet it says it was intercepted on October 20th?! Explanation please.

[Tanjianwei]

@livelobster123 cause i uploaded it in singapore and the time zone is different!!

Singapore time is +8hrs GMT

[RobCampo]

@Tanjianwei This is a message from the future! Trippy!

[Hamradioismyhobby]

Telemetry From Aircraft. Maybe Fax, or some other data uplink-downlink

[izelatlan0478]

Sounds like a data call with carrier. That sort of musical sound is how data transmission sounds....hetrodyning is natural phenomeon...Good God this takes me to listeing to sort waves and its strange whistles and pops and waiting for the morning twilight for the obvious twilight zone.

[MrWeatherman10]

that a DX siganal

[NikoLiberty1000]

Sounds like you found something broadcast from a number station.

[CatalinaTamiko]

Sounds like possible radio signals we ourselves sent out that is now reflected back, and distorted by space, heavenly bodies, and radiation from stars.

[leemer12]

It really makes no sense on the patterns, It does though sound like it is a synchronous type of mode , with MSK in it , but sounds like the level sometimes is below your squelch threshold, I have no clue why there would be a swooping sound, I do not see any benefit from using a technique like that.  Could be just testing out a transmitter at a radio station , but not sure what the data burst would be for.

[ThatKid573]

Well i think thats a signal from a radi....TACTICAL NUKE INCOMING!!!

[Quasimodo1957]

Maybe a 'numbers station" of sorts using tones only?

[HurricaneSondra]

sounds like the signal a tv station sends when it is just about to go off air, at first, but then it goes to what i think sounds like sstv or psk31

[mexicub]

Aol dial-up

[555555550]

it is a Decode

[Dartivesgu]

think is some kind of encrypted uhf data, proably some bank or low-confidentially military data. I think it's data because it looks much like dial-up internet connections while transfering data. Try to download something with dial-up connection and listen to the phone, it'll be a similar noise

[TheBroadcastEngineer]

CT4RK has it right, sounds like an audio Proof of Performance test being conducted ...

[Nissan021]

its some computer generated data being sent over the air to another radio and decoded by another computer, but it sounds broken up or encrypted .

[Remedynr]

thats the radio transmission from Jupiter, no joke. Check The universe - jupiter. Its sending random radio wave transmissions and radios can pick them up

[laslos3]

sound like data of some kind to me.

[bamnibaum]

Encrypted uhf transmissions. Banking transmission or so forth.

[TheKapitan98]

Sounds like the earliest computer known to man booting up. Like, what Fred Flintston used to connect to the Interrock. I was like, 5 when we got rid of a computer that looked like that...

[kasparovnutter]

ITS A NUMBER STATION

No lah,sounds a bit like a sstv signal lol.

[17SPIKE17]

MICROWAVES FROM A CELL TOWER...

[xlr8up]

This is clearly a TTY transmission, a friend of mine is deaf and that is exactly the strange tone his Tele-Type makes when transmitting analogue calls. 

[Waarghman]

Dumb fuck!!!

[MrStewie231]

@SuperWeaves ture!

[SuperWeaves]

@SlasherLink119 LOL

[mounsteres]

It's data packets.

[Erinwolfrus]

It reminds me a lot of dialup handshaking.

[illuminatioracle]

COME IN CADET STIMPY, OVER

[LABBChaCha]

@illuminatioracle Yes. Just, yes.

[savaloynchips]

transcoded message reads..... Mork to Orson ...com in Orson.

[shortwavesam]

some type of data! 102 mhz is fm here in australia!

[jjovereats]

@shortwavesam 102mhz is just below WAVE 105, so FM here too!

[Tanjianwei]

@shortwavesam Same here too..

[ajlusted]

Heard exactly the same thing in the months leading up to the launch of Classic FM in the UK in 1992, so transmitter testing. They also used to broadcast birdsong during the tests which became very popular amongst listeners (including myself!), as a result people complained when the birdsong tests stopped and the channel started properly (check it out on wikipedia)!

[4tt1]

it's an advanced weather balloon

[CStrieker]

this signal is often heard around this time of month every month at the approximate same time. it is (according to many scientific reports that monitor jupiter) a radio signal that is sent from earth where some of the escaped signals were amplified, rearranged, and then readmitted to the earth. it was once thought to be a message from aliens, but later discovered to be our own intelligence talking to ourselves.

[thepet3r]

@EliaForce1984ita time zone difference, perhaps

[MrShayneOneill]

@EliaForce1984ita Timezone differences. Its not that strange.

[PrincessPirate88]

Im sorry I tried calling you throught the radio again =)

[NZScanner]

It is undoubtedly a FM radio station test.

[theevilcruz]

This is a test of the emergency broadcast system lol

[horchan1216]

sounds like fax

[FailedSquare]

packet, and possibly calibrating things

[audiocombat]

sound like the freq test radio 1 do in the middle of the night, was working when they did it and it lasted a minute or so, this is'nt 99.7 or radio 1 freq so no dj talking before or after

[DouglasMcK]

Ive hear that too in brentwood,ca in the 90s

[DrMotorDude]

I'm not the first to answer it but it's RTTY. (Radio teletype.)

[MrSupasexi]

i would just like to point out that this was on my birthday

[viperx1977]

commodor 64 loading rambo first blood !!!

[mrethanist]

@viperx1977 LOL!!!

[RobeonMew]

@hondatuner816

that is exactly what it is. this is a connection test

[manka6]

stop capitalising everything for no reason. I can't take you seriously.

[jonvincent12]

Possible answer: That frequency is the TomTom RDS-TMC Reciever Frequency.

[reneeboobaby]

um alien ufo

signal

[59cva]

data link for unicom airport function

[lucadepu]

it's PSK data

[tributetolost]

Haha, I mic spam this shit on TF2.

[KlimaticEgo]

@tributetolost Spam UVB-76, loud. That's ten times worse than this.

[Raxian]

Sounds like a Amaeture RTTY Repeater for the old teletype systems. Basically the first sound is the Acknowledgement then the tone is a recognition of the TTY. Not sure what the "Whoop" sound is (it has been a while) but I think its a queue up.

[Tallyock]

I think part of it is the Alberta Emergency Public Warning System

[Tanjianwei]

Very Big Thank You to those who replied :)

[astronush]

@Tanjianwei well look for the only thing that could transmit data at a frequency of 102Mhz... also you should be listening to a neighboring range of frequencies to see if its just a part of wide bandwidth transmission .

[N0rthwestRadio]

at 102 mhz, that is commercial broadcast in the states. I would also think it would be elsewhere in the world. My guess, only a guess, it is a series of test tones with data bursts describing the tests and providing information about them. Using computers to test transmitters would be more efficient because it could send info such as amplitude and power settings for that test, then the test itself. A receiver would record that data for later analysis. Just a guess. Testing a transmitter.

[L0GAN811]

this happens all the time to me, if u live close to a hospital, you can actually hear an mri or a cat scan through the radio from long distances away.

[Thunderchicken1997]

Was this recorded at a time when the commercial radio station adjacent to this frequency would conduct the test of the emergency broadcast system? This may have been some inter modulation between the system computer and the commercial radio station. Weird, but not non-terrestrial.

[FourBinLabs]

If you listen to this, you can hear that each phase of the test is separated by that erratic tone. Some phases are silent (showing bg noise levels). Others go from low to high, testing over a range of audio frequencies. And others do other things.

[Aviator14]

102 Mhz is on the FM radio broadcast band, so it is probably just an FM radio station doing a test

[thedarkholeconsumer]

egh sounds like my dial up.

jk it might be some tests, nothing serious

[deloreandmc88]

LIE!it can be anything...

[nigginynoo]

It's simply an automated audio line (or RF link) test sequence from a Lindos test set or similar. The PSK tones you hear tell the receiver at the other end of the line or link to move on to the next test. Tests include frequency response, crosstalk, signal to noise etc. Nothing spooky - just routine testing.

[ZackFeuernt]

My GOD I can't listen to that sound from 0:00 - 0:44

[TheRealDj2quick]

sounds like encrypted stuff and then frequency tests

[sr71ablackbird]

possibly originated from a repeater ?

[bcboy3n2]

its not morse it's satellite

[TrappedunderIcE7]

sounds like a chain of....seems like morse code + frequency tones, probably satellite interference

[TheRandomSqueak]

sounds like you have dial up XD yeah most likely it was a test. or i was morse code

[Tanjianwei]

Thanks For Your Comments and replies!!!:):):)

[hackller]

this was a test from classic fm. they used to transmit country sounds as well. always remember this!

[AndersJohansson]

RTTY!

[SWL1409]

Strange...

[Wa3ypx]

It sounds like a burst of RTTY

[JohnnyX50]

It sounds like a Radio Transmitter test signal, similar to the Test Card used on TV broadcasts. It is designed to test frequency response and numerous other things technical. I remember when channel 4 was on testing before it went 'live' the logo was on screen and either music, tones or other sounds could be heard (Im talking way back in 1982 when ch4 was the 'new' channel)

[xx1929xx]

0:45

[CT4RK]

Hi

It seems the adjstment of audio response, and the modulation desviation of the a FM transmitter. I`m Broadcasting transmitter technician, and use a setup for adjustmente of the transmitters that make from single tone to a gausian complex noise, for adjustment os modulation. Normaly we make this tests during the night in dead hours.

[cookingboy3]

@CT4RK What Is RTTY?

[offthahook08]

Sounds Like HAARP, or a Satellite!

[Dusty696969]

When I scan on way high freqs I find these all the time. I just scan past them. If I dont understand what it is I dont bother.

[Letsgoherd3008]

This is the same signal, sound, and tone i am receiving at the freq. 131.087-5. I researched it and it is caused by a fixed satellite for Aeronautical Navigation And Radio Transmissions I live 5 min. from a private airport and asked a friend who worked there and he said it same one they used in helicopters to life light people

[republicansarecool]

looks like someones modem is all messed up.

[rj719]

I use to hear the same one using an old black and white tv i use to play with when i was younger

[JayL1212]

The data transmission sounds like a PSK/FSK signal, and the tone at the beginning could be a pilot tone to indicate the start of transmitssion or to tune the receiver into the right frquency. As it is on the broadcast band it might be a commercial radio station doing some experiments with their transmitting site to check coverage, etc.

[bhconnectionjigsaw]

dang man u r clever to know these things :P

[journeyearth]

Yes all noises you hear are sent by a spectrum analyzer test set. Jayl1212 is dead on. Cheers

[c222]

I agree. However, it sounds more like RTTY to me.
