KrakenSDR is a 5-tuner coherent software defined radio based on RTL-SDR. It is the successor to the KerberosSDR and will be crowdfunded in 2021.
In this test KrakenSDR is used as a radio direction finder to determine the bearing towards various commercial transmitter towers located around the antenna.
The test shows how the KrakenSDR automatically recalibrates on frequency change. Unlike the KerberosSDR it is no longer necessary to manually disconnect the antennas and then recalibrate during each frequency retune.
The DSP software running on the Raspberry Pi is entirely open source and available at github.com/krakenrf
The Android App is closed source but free to use for non-commercial use.
The Arrow Antennas 5-element antenna array will be available for purchase during our crowdfunding campaign at a discount.

very interesting.
What about VFO-0 frequency when changing the central freq
Looks like you need to turn your array as it's off consistantly in a clockwise direction.
man if it went up to 6ghz id buy it in a heartbeat

We are working on a 6GHz coherent receiver, but it will be a completely separate product. It will also be more expensive than the KrakenSDR.
Their webpage says not to use the different band elements at the same time to avoid reflections. I'd be curious to see how it effects its RDF ability if you just had all the elements installed at the same time. I'd also be curious how big the bandwidth is for each size elements.
@The Kraken I bought a copy of KerberosSDR a few months ago. Would it be possible to trade with this new model ? 😛
Thank you for this video, and what is the name of emulator you used in this video???

It was the Android Studio emulator for development. But something like Bluestacks should also work.
Given we know the exact position of emitters , and assuming we use topographic maps . Could the setup self adjust it settings to make itself more accurate?

That's something we'll be looking at in the future. To see if we can use known fixed transmitter sites to help calibrate out the effects of multipath. As of now it's just a possibility.

Noting that it's not only topography that affects multipath. Different materials (dirt, sand, water, grass vs road vs forest etc), buildings, foliage type etc all change multipath properties.
Is this the Interferometric method ?
How can I get one?
Where did you get the fancy Raspberry Pi case?

Sorry I can't recall right now. I believe it was just on Amazon or eBay. Was a fairly common case.
Cool where would I find this? Just back to t hunting after 15 years. Cool. Oh crowd funding, hope it goes well. Not good luck with crowdsourcing lately. Cool stuff well done sir.

Thanks! KrakenSDR will be on CrowdSupply within a few months from now.
I cannot see that cool antenna. Is it for sale? Construction diagrams?
