I appreciate your work, but in this case I think 6911 is a dedicated pirate. Several months back I'd heard the Buzzer, air raid sirens, and music. I'd also seen a report of text in the waterfall, something to the effect: "Buzzer is fake, I'm real!" Eventually they followed 7032 etc... with an hour of anthem. Unless the other stuff was unrelated to the current user?

In this case this transmission was TDOA'ed (multiple times, by different people) to inside Russia. So if it is a pirate, it is a pirate inside Russia on known Russian military frequencies, and while that (a pirate) is not impossible, it seems unlikely to me. To be sure, there is much pirate activity on Russian freqs, but I think a lot of stuff casually identified as "pirate", might not always be so.

" Are you talking about the signal in this video? It is not interference. It is a radar. The waveform is very clearly FMCW. Not sure what you mean by "VLF radars". I have never heard of a VLF (Very Low Frequency, the frequency range from 3 to 30 kHz) radar, and certainly not one for detecting ICBMs. There are several different HF OTHRs (High Frequency Over The Horizon Radars, in the frequency range 3 - 30 MHz) today, several designed to detect missiles, including ICBMs and shorter ranged missiles. The Russian 29B6 Container and the British PLUTO radar are just a couple, and the PLUTO uses a waveform very similar to this signal, if a tad more narrow.

@jublywubly said "That's metre, not meter. A meter is a device that's used for measuring. The unit of measurement is called a metre." Re meters vs metres, "meter" is a US English based recognizable spelling for the unit of distance measurement. Since I speak US English, that is what I used. Since this is the second time someone has pointed this out, I suppose I could have just converted it to feet. However, I wanted to use the more conventional radio band designation of meters, vs the successfully put humans on the Moon unit of feet.

On HF, sawtooth is by far the most common, you almost never see triangle, and I have never seen triangle that holds at either end, or one that changes chirp rate PRI to PRI. For that matter, most of the FMCW and FMOP I have seen at microwave frequencies also are sawtooth.

This signal belongs to the high frequency trading firm DRW. Their US signals are licensed under Skycast Services LLC, and their wireless infrastructure team works out of Montreal. Do you see similarities to the Canadian Meteor Orbit Radar signal--I believe developed at Western Univ of London, Ontario, CA? BTW, the other trading shortwave signals that you analyzed a few years back belong to Raft Technologies, who licenses its transmitters under 3DB LLC. Have you analyzed the Parable Broadcasting signal, which is transmitted out of Batavia, Illinois? That, too, is a shortwave trading platform. I think you'll find it interesting. Strong signal. Trained on the EU. You should receive it well out there, as you're nearly on path (off the back end of the antenna). I can point you to it.

@@campandcook3118 said "They were located close to the other plants at Chernobyl, because the over horizon radar used as much power as a small city" This is often repeated, but really does not have a lot to support it other than word of mouth. There were 2 Duga radars, one near Chernobyl and the other in eastern Siberia. The one near Chernobyl was indeed only a short distance from the Chernobyl Nuclear Power Plant, but the other was not near any nuclear plant. Also, the Chernobyl Duga radar was active before July 1976, but the nuclear plant was not commissioned until late September of 1977. That means that the Chernobyl radar operated for well over a year before the nuke plant was possibly supporting it.

Is this what you mean by HFT signals? Your saying they use HF radio to transmit the data? High frequency trading signals mean quickly buying and selling stocks using advanced tools and algorithms. This allows traders to make the most of tiny price changes and time their trades perfectly. These signals come from trading firms and hedge funds.May 26, 2024
@FirstToken
@FirstToken Ай бұрын
HFT is, as you say, quickly making decisions to buy / sell. The firm or algorithm that sees the trend first makes the most money. Radio links for data and decisions are faster than cable or fiber links. Various firms have used this fact to leverage a speed advantage in noticing trends. Yes, some companies are working on using HF radio to provide the lowest possible latency in decision making. This callsign is apparently associated with one of those companies.

@BrianMorrison said: "There were 3 of these simultaneously in the 7.0-7.2MHz amateur band the other evening, unsure of their locations but all quite strong on a TFD antenna in the UK." Do you have a date and time? This one was sourced, almost certainly, in Asia, so it is unlikely you were hearing the same one. However, there are several other candidates that are probable for you. Off the top of my head I would say most likely the Russian 29B6 Container radar, but with a day and approximate time I could confirm it. For example, I see that on 18 Nov, at about 1800 UTC, the 29B6 was indeed hitting the 7000 - 7200 kHz range.

Ala the old "Woodpecker Hunting Club" technique. Sure, you could probably do that, but it would require a more complex transmission than the old "send Morse dits back to them". One advantage of the FMOP waveform is that it handles interference a bit better than the old BPSK modulated pulses of the Woodpecker. In order to be really effective you need to cover a large part of the occupied bandwidth.
