3393.0 Khz @ 1045z on 2/19/2011

Hearing what sounds like digital RTTY or a digital FAX signal. Doesn't sound like anything I've heard before.

I'll upload a short sample later.

I got it here still at 1450utc Nick-I googled the frequency..not much info on it..it sounds like a diesel engine inside a large pipeline. Definately has the creepy factor!

Hmm... I've heard stuff like their example many times. I think there's other stuff that might sound similar to it.

Per this web site, it should be HAARP: WHAT THE HAARP SIGNAL LOOKS AND SOUNDS LIKE
]

I have a few problems with that page, not the least of which is the authors contention that HAARP also sends ULF waves, but he could not show you an example because his radio has an audio roll off of 30 Hz.

The next is his discussion of "non-radar-reflective" paint and how that made SDI impossible. Ummm, hogwash. SDI might have been a pie-in-the-sky project, or it might not have been, but no stealthy material designed so far would survive reentry.

And yet another reason is his description of a HAARP "shield" that negated the Russian ICBM nuclear threat, and thus led to the fall of the USSR.

Unfortunately I do not think that is HAARP. Two reasons, first your recording does not sound like HAARP emissions that I have received (however I imagine they have multiple modes, so that does not really prove anything). Second, and most importantly, this web page Spectrum Monitor Waterfall Chart does not show any HAARP activity at that time. When HAARP is active you can see it on that waterfall clearly.

Thanks for the link Token. FYI, just to be clear, I'm not saying it is HAARP -- I'm just curious as to what it is...

I'll see if it happens again tonight and if so, I'll hook it up to the PC and get a waterfall output.

It would be easier to search Google if there wasn't some rap artist using the name HAARP. :twisted:

Okay it's back. I'll try to capture a waterfall of the frequency. If anyone with a SDR can beat me to it, I would love to see what you can get.

3393khz. Right now the signal is about S5. It'll likely get stronger as the night goes on.

Interesting. I have a signal here that sounds just like the Haarp 'diesel engine at the end of a pipe' description on 4250kHz and it's continuous 24/7. Must be very close as it is 20 over S9 where S9 = 50uV in 50ohms. 4250kHz is the centre of the signal, if I make it all USB then the suppressed carrier would be on 4248.5kHz. The 'modulation' is almost exactly 3.5kHz wide.There are no tones like the recording, but every so often there is a break in transmission for a second or less. I'll do a recording/pictures/waterfall sometime.

There are a couple of 'interesting' radio sites around here, the military about 150km North, a marine HF station about 130km north AND over on the coast about 15km west there is a 'receiving' site with one of them 'bullseye' (AN/FRD-10) antennas. You can see it on Google Earth but you can't see it from the ground due to the pine forest all around it. A farm entrance on the road has some strange official looking "Trespassers etc...." notices. Hmm........:)

Unfortunately I haven't found how to put a sound file (WAV?MP3?) up here, but here's a coupel fo pix of my unidentified signal...It's still s9+ in the middle of the day.

42485kHz.jpg


This is a pic of the signal with 4248.5kHz in the centre and the gray outline is the filter bandwidth, so you can see that the 'noisy' signal fits neatly into 3.5kHz USB.

This is a waterfall of the sweeping signal. You can see that the 'noise' has a decreasing centre frequency in a sort of spiral fashion. the zero frequency on the left is 4248.5kHz. If I was going to describe the sound, I'd say it was like waves breaking on a shingle beach but slowly! Not so much the crunch as the wave falls, but the rattling all all those stones as the water recedes....how's you imagination!

Hope someone has seen this before! :)
