The software really depends what you want to use it for? The HackRF is mostly for hacking and experimenting, so GNU Radio.

Other than that, GQRX.

The loop will most likely work the best. A cheap Chinese loop is fine, but as you're in the UK look up Welbrook loops too. Obviously much higher cost, but really well built.

Nothing like that available for everyday man prices sadly. There are a few machine learning attempts on GitHub, but nothing really ready for actual usage that i've seen yet.

Any idea yet when the v2 hardware will ship? I am going to do an antenna upgrade in the next few months and was hoping to mount one at the same time.

It will still be a few months out unfortunately. Crowd supply page here: https://www.crowdsupply.com/krakenrf/krakensdr

For bandwidth just use the largest available 2.56 MSPS. Yes screenshots are very helpful to see what you're getting. If you like a map showing the geometry of your setup could help too. And do you have two TV Yagis in your setup now? Make sure that the cables are the same length and low loss. You mi...

KrakenSDR won't be designed for outdoor use, but you could enclosure it in your own waterproof box (probably needs a fan though). Kraken will draw about 1.5A, more if you're using the bias tees. I'm not sure how it will operate with such a long USB cable though, even if it's fibre. I'd guess that an...

Don't use MEM, I would recommend using the MUSIC algorithm first.

Can you provide some pictures of your setup? What are you using to test?

Are your calibration graphs looking nice and straight with the antennas disconnected?

Just use the drivers, the software they included with the drivers is old and probably broken now. Plenty of other options like ProgDVB.

Please consult the guide at www.rtl-sdr.com/ksdr You need to perform sample and IQ sync first after booting the Kerberos, or after changing frequency. This is to achieve phase coherence. For FIR filtering, the value is how "tight" or "sharp" the filter is. Basically how rectangular it is. The gain w...

What upconverter do you have? By using an SDR + upconverter you're doubling the potential drift. Make sure both have a TCXO, and keep the ambient temp stable.

Those all in one units will probably drift much worse, as they usually do not have a TCXO.
