Hi, to all after I've seen with RTL ADSB and DUMP1090 how ADS-B transponder data 1090MHz (pulse modulation) is decoded I would like to start with FLARM (Europe 868.2 and 868.4MHz frequency modulated). The position data of gliders (ID, latitude, longitude and altitude) are sent 1xsec in the form of NMEA-like records. I work with the BeagleBone black and have a FLARM transmitter installed near the RTL-Dongle/Antenne and may at any time start recording I/Qsamples with RTL_SDR. Thanks Fritz
