Gnu Radio. Newkirk called them the unsung fathers of amateur radio. Gnu radio is both a python library and graphical front end for generating python radio programs.
Starting from the beginning heather will introduce the gnuradio programming environment develop a little of the theory needed to understand sdrs and then go on to use some simple gnuradio blocks to build a receiver based on one of the super cheap sdrs. Gqrx is a software defined radio receiver powered by the gnu radio sdr framework and the qt graphical toolkit. It supports many of.
It can be used with readily available low cost external rf hardware to create software defined radios or without hardware in a simulation like environment.
However if you are a daily windows user and want to play with sdr building it on windows is a huge challenge even in linux. Newkirk called them the unsung fathers of amateur radio. Users create programs by dragging blocks onto a workspace and connecting block outputs into block inputs. It can be used with external rf hardware to create software defined radios or without hardware in a simulation like environment.
