Setting up SDR-RTL on Raspberry Pi 4 was quite easy.
- Installed CubicSDR
- Attach SDR-RTL USB device to RPi4
- Start with menu at Other>>CubicSDR or from terminal CubicSDR
I had a little trouble with getting the sound thru the speakers. Basically on the CubicSDR, the audio being routed to HDMI verse Analog.
Also note, that I tried running on RPi3 and had mixed results. Sometimes it worked and other times it didn’t. It’s CPU intensive and think the RPi3 just doesnt have enough power.
