close encounters...?

Hey Sol-interesting that you got it there too since you're 7-8000 miles thataway! What was the signal strength there and was there any fade-it would be cool if we at least could get some bearing on this thing. I get it at a steady s5 here but clear and no fade. Depending on where this originates from-the "no fade" could be an indicater of its nature. I have it set in the vfo to be there every time I fire up Rosie don't like it-it creeps her out!
Datainmotion-you got it the strongest there in Colorado so far.

By the way-I should note that I get the strongest carrier on 6837. When I tune to 6836 the carrier is almost gone and the sound weakens-this is why I call 6837khz.

Definately sounds like feedback-but here's my thinking-been going on a heck of a long time-we aint the only ones who can hear it. Why when you google the frequency-nothing stands out as an explanation? If someone is manipulating it-why bother for so long and for what reason? Why hasn't it been killed by the FCC if it's a prank? It is always on this frequency and pretty much 24/7. That makes me think it's fallout of something else-it used to sound like whales-not any more. Well-off to go digging around some more for some explanation.

Lets say you have a collection of hardware that is redundant. Radio model A, hooked up to amp model B, using duplexer model C, patched into antenna model D, sitting next to second radio's antenna E, and so on... Then you have that same exact system repeated throughout a certain ship type, ground stations, or whatever... Same cables, same configuration, same inherent flaw... which creates the problem under certain circumstances... Thus, randomly keeps getting repeated.

Personally, it sounds completely random to me. I hear no intelligence in it. I don't imagine it actually serving any purpose.

Yeah I agree-that's why I said I think it's fallout from something else. Funny how there isn't much out there in webland about it. I think it's frikkin spooky honestly

If you look up backwards music, there's some stuff. But most of it is conspiracy theories.

I was listening to the signal tonight (02/21/11), around 0430UTC. Same signal.
The signal ended around 0445UTC, and at 0450UTC I heard foreign sounding voices. Very weak copy.
It's on YouTube at YouTube - Unknown Strange signal, aftermath
At around 0500UTC, the melodic tones began once again.

Must have some grunt behind him 'cos he was S3+ here at 0800z - sounds like a wobbly carrier - if I tune to 6836 USB I get a tone about 1kHz which then slowly falls down to 800Hz, then the 1kHz tone comes back and the 800 fades out - repeat every 5 seconds or so. Weird.

Thats it Im calling SETI !

Nothing the last couple nights..

Good day Ridgescan. listening to this signal at the moment at 0900 GMT on the 27th lot of QRN and very weak. I suspect it's a sideband signal, hard to tell if it's USB or LSB or the exact frequency. I'm thinking my previous post was wrong this not a WX fax. Listening to it at the moment I'm hearing a series of harmonic notes that resonate in certain combinations that give it a weird combination of sound.
Two thoughts here,
One, it's some ones idea of art (very unlikely)
Two, a digital signal that may be phase, frequency or both encoded. Just because we haven't heard a mode like this before it doesn't mean it doesn't exist.
Its a very narrow signal that's sweeping about a 150 HZ (AUDIO) wide and another signal is imposed on it at the end of the sweep giving it the resonant whale sound. It then starts again.
Got me curious!

Found a radio database site that lists 6.836 MHz as a US MARS frequency. Follow the link for the info on MARS stations. Military Auxiliary Radio System - Wikipedia, the free encyclopedia
If it is one of these stations it's still a mystery to me, why the whale songs?

Well, I still can't make much sense out of it. Here's what I got tonight between 0730 and 0800z good signal ranging between S6 to S9+. I plotted the audio on SpectraVue. Radio set to 6836kHz USB. I was doubtful whether the drift was my rx or the soundcard drifting so the straight vertical line at the bottom is the carrier of WWVH offset by 1500Hz which as you can see is dead straight. As you see the 'tones' are a whole series of decreasing tones about 700Hz apart and then just strengthened in the area of 1500Hz - so at any one instant what you hear is the loudest tone decreasing in frequency which then pops up again only 700Hz higher. This is not the same signal that I heard previously although I didn't have my laptop handy to plot the spectrum then. It's unfortunate that at the moment I captured the screen that there were no tones showing in the spectrum - usually they were quite visible.

6837USB Sounding really creepy tonight

 

[Sol100]

I'll have a listen and see if I can get some audio for others to compare.

 

[ridgescan]

I went on 6837khz usb to see if the sounds were there-and am hearing Spanish comms on said frequency. Hmm-this is interesting right?

 

[mkrubsack]

One fellow posted a reply to my YouTube posting of this signal, saying it's something called XM-Whales.

See http://www.hfunderground.com/wiki/XM

There's a YouTube link on that page, and that signal sounds pretty much the same as what I've heard.

All Quiet

Frequency has been quiet here is Perth. I still tune in from time to time hoping to get a decent signal, we are all at the mercy of the band conditions.

Here too Sol-it's on my regular watch nightly and it's been dead. Which post had that URL in it?
