Software Defined radio on the Raspberry Pi 4


Well-Known Member
while doing some research on Software Defined Radio Control, I was directed to the link below

This is a text document with the commands required to install the GNU Radio Companion, and other software in Raspian Buster. I copied and pasted the instructions, one at a time, and found that there is a missing instruction between lines 13 & 14. Insert the instruction mkdir ~/rtl-sdr between lines 13 & 14, and it works fine.

Gnu radio Companion runs with no device connected, but rtl_433 fails if it does not detect the USB module.

Hopefully this correction will keep someone from pulling their hair out, or at least some of it;)

Happy Trails,
