Re: Share your results

By the way, I forgot to mention that if you long press on the map in the Android app you can add a marker to mark the known or suspected location of a TX tower.

Re: Android App connection error

Got it figured out. The android phone I was using had not data plan on it only voice. The Kerberos app does not work on wifi only mode. Got another phone and it's now working. That's odd, it should definitely work with WiFi, there is no need for a data plan. e.g. first connect to your normal wifi, ...

Re: cb transfer status: 5, canceling

I have one PC (a laptop with USB-C ports) that is capable of powering and running the KerberosSDR with just the microUSB and a high quality SHORT cable. But most other PCs I have don't seem to put out enough power. You will need a separate power supply if you're PC USB ports can't put out enough pow...

Re: Share your results

Not bad at all! Next steps for the app will be to find an algorithm that can find the center of the cross points.

Re: Old laptop Acer aspire 5100 sdr#

I Googled Amd Turion 38 mk, and it appears that it's only 1 core. So I think it would be quite slow. Generally at least a 2-core processor is recommended.

Re: Feasibility of a Passive Weather Radar

Weather radar actually operates at 2-4 GHz, so outside the range of the RTL-SDR. Only these frequencies really reflect clouds and rain. Also the bandwidth is probably not large enough to get any sort of resolution. That said, I have noticed that on windy days I can sometimes get patterns across the ...

Re: cb transfer status: 5, canceling

Do you have any other RTL-SDR dongles that run on the machine? I've seen others post about this error on Reddit, GitHub etc, and it seems to be something to do with the USB port hardware not functioning correctly. Some people had success when disconnecting other USB devices plugged into the PC. Anot...

Re: Testing the 4 rtl- sdrs

That's expected, because when you have only one SDR on, the device index will always be zero. I would test like this: Turn on SDR on, and test with -d 0 Turn the second one on, and test with -d 1 Turn the third one on, and test with -d 2 Turn the fourth one on and test with -d 3. Don't turn the prev...

Re: KerberosSDR & Aircraft Beacon Search

then you're still looking at an antenna array with a radius of 0.75m which could be quite difficult to drive around with. For that, I do agree, in the rigor realize a removable installation would be the ideal, but it is "wasting time" during the search for the aircraft (in real situation) which is ...
