Well it was working fine but I’ve obviously done something to mess it up
was giving me the standard text screen display but now all I get is
rtlsdr: no supported devices found
My system consists of a RPi with airspy.
I installed the FA SD card image then used the Wiedehopf instructions 1a
A google search has not shown up anything pertinent so I’m asking here.
Drastic measure would be to re-install the FS SD card image again and redo but hopefully it is just a configuration that I have mistakenly changed somewhere.
