Re: ACARS Multichannel Decoder

What sort of problems did you have?

You can also try using Acarsdeco2, which is a bit more popular http://xdeco.org/?page_id=30

Re: Integrating the RPi

The GPIO pins aren't really meant to be used at the moment, they're reserved for possible future use. If you wanted to use them now, you could use a GPIO extender to connect the Pi to the board, and that the Pi would be powered via the header. But you need a powerful 4A+ USBC supply if you want to d...

Re: Trouble running demo software?

Maybe you also installed librtlsdr-dev via apt-get? Try removing that too.

If that doesn't work i'd suggest searching your system for old librtlsdr files, and deleting them all first.

There is a driver conflict somewhere on your system, so finding and deleting those old installs should help.

Re: PLL Not Locked! error? No Demo software functions.

PLL not locked is fine, not an error to worry about. rtl_test indicates that RTL-SDR 0 is working fine, but you should also test -d 1, -d2, and -d3 just in case. When you booted the Pi, did you have the KerberosSDR plugged in and powered up? Plug in the KerberosSDR before starting the Pi. If you plu...

Re: RDF Compass Issue

Yep was just looking at the compass today and noticed that it wasn't working. Will be updating that in a new image version being released next week.

For VNC, it's using the default Raspbian login pi/raspberry. I updated the guide with that info, thanks.

I am getting errors when running setup_init.sh on x86 with 18.04. No errors on any prior steps and all rcvrs test good. Any suggestions?

Re: Trouble running demo software?

The Pi3 is a bit slow, but I've never seen it freeze up. Did only the software freeze, or the whole system?

Make sure you turn off the spectrum and sync graphs when you're done with them. Plotting those graphs can be quite CPU intensive.

Re: Cant keep V3 Bias Tee Enabled

What RTL-SDR drivers have you installed to your system?

I think some version of the older drivers had init code in it that would turn off all GPIO ports. Try unisntalling the RTL-SDR drivers in your system and installing the latest osmocom drivers.

Re: Odroid XU-4, C1, C2, C0 compatibility

Yep, no errors mean that it imported correctly, so it should be fine.

Re: Odroid XU-4, C1, C2, C0 compatibility

If it says "Successfully installed scipy-1.2.1", then it should be okay. pip does sometimes throw errors at first, before successfully installing programs. To test, go into python3 at the console by typing in python3, then trying "import scipy". If no errors are thrown, scipy was installed successfu...
