I sincerely look forward to this new generation. I missed out on Kerberos, and we have a significant amount of work to do on locating sites on several trunked systems for the RadioReference database. This is going to be a critical tool in the field for that! Can't wait!

Do not use a generic USB data cable, even if thicker and literally brand new. Caused my setup to not work. Switched to 3ft Anker I had laying around and all good. Also, have a good 5v USB powersupply, or two separate ones. I bought a 30w down buck converter with dual USB C legs. Also bought some 5A cigarette adapter power supplies for backup. These two issues can have you pulling your hair out!

Ordered mine today!

Super cool and good 😊.

Impressive.

This is awesome. I'm looking forward to eventually ordering one. I do have a question, and sorry if it was mentioned: would it be possible to have three cars, each with a unit which reports to the same server in order to dial into the source of the signal, quicker? Nice work.

It will be possible once we have our cloud software released. The app or Kraken Pi server will upload data to the cloud server, and combine information there. We're still working on this software, so please keep an eye on the updates in the near future.

I can't find anything about it online but is it possible to do this with other SDR's? I am trying to find a software or something that will let me track signals but I only see for the Kerberos which I have to recalibrate every time I move.

I would be interested to see this for intermittent transmissions. For hunting two way radio sites.

This is awesome. When will it be released? And for how much? Any chance of an early order?

We're planning on releasing very soon, just finalizing a few things now. Yes pulsed signals do work but effectiveness does depend on pulse duration, pulse bandwidth and power. Very short

@thekraken2086

They were at about 17dBW EIRP output. The minimum power is difficult to say. If it's a direct LOS signal, with no multipath, it will likely still point in the right direction even if the signal is weak. If it's a high multipath environment, the bearings will be corrupted at higher signal levels.

Wondering which kind of signal is transmitted at 416.588MHz?

is this for HAM radio jannies?

Red/Green circle is POS of transmitter, but what is the black dot ? I have a number of issues with the DoA jumping all over on my Kerberos SDR - as it often does on Kerberos demos videos. Looks like Kraken is much more consistent ?

@thekraken2086

The black dot is just an averaged location for the turn-by-turn GPS path planner, only used before there is any confidence in the TX location. In high multipath, or high movement environments (cars) the DoA will jump around a lot, that's just the physics of the situation. You need either move to a good location with good LoS and take a high quality reading, or use the app and essentially average many readings. That said, 5-elements instead of 4 does improve on multipath distortion, so Kraken will be a bit more accurate.

How well will this work for tracking moving multiple signals that are intermittent (say voice chat). All within 20 miles of an active base tower on the same frequency? Will there be too much noise?

@thekraken2086

Жыл бұрын

If multiple sources are being interleaved on the same channel it gets more difficult. You'd need to modify the code to somehow ignore the base tower transmissions on that frequency, and only focus on the mobile transmissions. If there is some sort of sub carrier squelch signal available that could be used. Then another problem is keeping track of each of the individual moving radios and matching them with the bearing logs. You'd need some way to ID each radio, again maybe with a squelch sub carrier signal, or similar. None of this is in the code since there are so many different systems, so it would totally be a custom coding job for your particular system.

This is what I would want it for. It would need to be used in a "freestyle" mode where it won't bother trying to "guess" where it is on a map and the user just needs to use their head to "filter" out the signal corresponding to a particular voice. It looks like it sort of already does that.

How does it tell the difference between reflections off of mountains and the actual signal?

@thekraken2086

8 күн бұрын

Multipath is generally weaker than the actual signal so the actual signal lobe is dominant. However if the actual signal is blocked, and multipath is dominant, then the multipath lobe will be larger. That's okay if driving with the Kraken. Multipath lobes are mostly in random directions as we drive along, so over the mapped space the multipath averages out, and only the actual signal direction remains.

Drone test it yet?

Unlike KerberosSDR, KrakenSDR has built in switching hardware that when combined with the new software, will automatically achieve sample and phase calibration without needing to manually disconnect the antennas each time the unit is powered up, or each time the frequency is changed. This allows for much easier mobile and remote use scenarios. The addition of the fifth tuner also allows us to use a five element antenna array, which results in much improved direction finding accuracy and better multipath rejection. USB-C is also now used on both ports for greater port reliability, the PCB has been redesigned for lower noise, software controlled bias tees are present on each port, and it comes in a tough CNC milled enclosure that doubles as a heat sink.

I don't think that this system, as demonstrated, is quite achieving the theoretical maximum possible performance. Perhaps it's the cluttered environment. Might be worth debugging and fine tuning in a clear field (if you haven't already) to ensure that the messy directionality is purely a function of the complicated environment.

Very good job, but it is half of what one friend of mine needs. He suffers attacks very likely in the microwave spectrum. He can detect with an android app that he produces ultrasound waves with very weak signals in two frequencies 40371 Hz at -68 dB and 55624 Hz at -68 dB. He found sometimes and very weird additional signal at 23000 Hz exactly. That fact produces a buzzing sound or tinnitus in his ears that makes him awake. His hypothesis is that microwave sources that he should locate interact with human piezoelectric collagen to produce these ultrasound signals but doesnẗ know if there is any mathematical relationship between ultrasound generated and microwave sources. Also, he suspects that he could be the microwave source and there are two scalar wave beams that by interferometry produce a microwave source in his head. How can this be researched?

@TheBauwssss

Жыл бұрын

If it is really as you describe, then there is a very simple way to test this. He should try covering his head with something conductive, grounded metal works best. Such as sleeping with his head inside a metal box with preferably a copper grounding wire attached to the metal. Depending on frequency the grounding wire may not even be critical for the metal shielding to be successful in sufficiently attentuating the signal as to make it virtually unperceptable to him. And this is going to sound ridiculous, but even just wearing an ungrounded tin foil hat of sufficiently thick aluminum foil with sufficient coverage of his temples, ears, neck and underside of his chin should be able to do the trick, if not perceptibly reduce the discomfort of this signal, as long as it really is an electromagnetic signal (and not an acoustic signal for example) that is to blame for this.

@@TheBauwssss Yep, thus the Tinfoil Hat meme. That said, it's a good approach to quickly and utterly disprove the assumed source. You don't need a "ground wire" at microwave; think about how many wavelengths a ground wire would be a microwave, useless.
