Hello,
I am fighting with a high noise floor on the Pi which is about 40dbi higher vs when the same gear is plugged into a computer next to the Pi.
I get the high noise floor even with an antenna unplugged and gain set to nothing.
Tried different Pis, power supplies, rtlsdr dongles, antennas, grounding the Pi. I assume the Pi is hyper-sensitive to interference but is there a way to prevent that?
Encasing it in a metal box?
Thanks
