Hi I'm new to gnuradio and to gr-adsb, I am using it for my Bachelor's thesis but I am strgling while running it:

Executing: /usr/bin/python3 -u /home/TFG/gr-adsb/examples/adsb_rx.py

The USRP Source is only compatible with Ettus Research USRP devices. You'll need to swap out that source with a compatible one for your device. What dongle do you have?

I'm using a RTL-SDR.COM dongle with and RTL.2832U

Check for a block called "RTL-SDR Source". If you don't have that you can install gr-osmosdr to use the RTL dongle with GNU Radio.

You'll need to set the center frequency to fc and the sample rate to fs. You'll also need to play with the gain settings too.

You can find tutorials online of people installing the software and using the RTL-SDR for listening to FM radio, etc.
