Hmm weird, thanks for the screenshot. I'll get him to look into it.

Also might need to know what country are you in?

Could you post some screenshots? Also what model phone and Android version do you have? I'll get the Android dev to look into it. The manual mode is a bit tricky at the moment. You need to rotate the map, and that sets the manual heading. In a future version i'm going to have him change it to simply...

For scipy if you're having trouble on a Pi3, you could try installing it from the repo's instead.

apt-get install python3-scipy

But if you're on a Pi3, why not use the provided image?

What is the actual difference between the RPi Tinkerboard image version and the regular KSDR util image? That (among a plethora of other things) isn't described in much detail anywhere. I'm not sure what you mean by the regular KSDR util image? There are only two images. One for the Tinkerboard and...

OK, that reply confirms my suspicion. Please have them read the USB spec to come up with a spec compliant way to do a power sink with a USB-C connector. Again, you need pull-down resistors there, not pull-up. So in summary the only option of powering through this connector is to try and get a non-c...

It's definitely worth the trouble to try and understand acarsdeco2. It's performance is miles above the others, and it can decode multiple channels simultaneously. The setup of other programs like acarsd are arguably even more convoluted, because you need to set up a receiver program, audio piping s...

However this does not clarify whether i.e. the FM Filter should be in the signal chain right next to the LNA unit, or right next to the RTL-SDR dongle's input (= after the antenna, LNA and the coax cable run). If you're placing the filter after the LNA, it does not really matter if you put it right...

Yes that's right. Considering a car is typically at least 1.7m in width, if should fit easily. Batch 2 of KerberosSDR is currently available for preorder at http://indiegogo.com/projects/kerberossdr-4x-coherent-rtl-sdr/. Because it's in preorder it's already discounted, unfortunately we can't discou...

Have you been through our ACARS guide at https://www.rtl-sdr.com/rtl-sdr-radio-scanner-tutorial-receiving-airplane-data-with-acars/ ? You shouldn't run the .exe directly, you need to run the .bat file. First open it with Notepad and edit the --freq-correction and --gain flags to more optimals ones f...

I'd like to revise my statement about 121 MHz and antenna sizing. My experiments with spacing factors below 0.33 seem to work out okay. So I think an interlement spacing factor of about 0.2 - 0.25 might be sufficient. And see the revised calculations for a circular array on the guide which results i...
