Hello,

I would like to share Toulouse-Blagnac Airport (LFBO / TLS) ATC with a PCDUINOv3 server.
Toulouse Blagnac Airport, is the airport of Airbus Industrie, where Airbus like A380, A350, A400M are built and tested. All tracker site (FlightRadar24, Flightaware, Planefinder, VirtualRadar, ... ) show aircraft track via ADS-B, even on landing and taxiing. It would be great to offer the possibility to everybody to listen the tower frequencies of this airport via www.liveatc.net.

MY PROJECT is to use a PCDUINO, a micro-computer of low watt consumption (about 5W-10W) and a low cost RTL2832U/R820T multiband to feed frequencies of airport to www.liveatc.net . The low consumption of PCDUINO permit me to keep the PCDUINO server online all the time. The consommation of a computer is too much for me.

Has somebody already tried that ?

For the moment, I can not go further. The low-level driver works (RTL-SDR). I can control gain, frequency tuner, and have signal data.
Nevertheless, I don't know how to demodulate the signal in AM, and I can't install GNURADIO (compilation failure : "libvolk.so.0.0.0: référence indéfinie" in compilation of "git clone http://gnuradio.org/git/gnuradio.git").

I keep searching. If somebody have some piece of advice to share, don't hesitate. If I succeed, www.liveatc.net will be able to add airport ATC feed, and not an ordinary airport : Airbus Airport !

I thank you, and looking forward to sharing with you all information that could help me to realize my project.

Guilhem
