Installazione della chiavetta USB con chip RTL2832U.

sudo apt-get install gqrx-sdr rtl-sdr

quindi

sudo nano /etc/modprobe.d/blacklist.conf

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830

comando

rtl_test

Se restituisce questo errore potrebbe essere necessario sconnettere e riconnettere alla porta USB il dongle RTL-SDR
