after that I wanted to test rtl_433 over tcp so I ran sudo SoapySDRServer --bind=192.168.0.1:1234 on the rpi3b

and ./rtl_433 -d "driver=remote,remote=tcp://192.168.0.1:1234,channel=HiF,device_id=1" on the client computer which spewed out this as rtl_433 was trying to listen actual RF.

reader thread failed to read SMI!
