Gnu Radio. 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. Gnu radio is a free software development toolkit that provides signal processing blocks to implement software defined radios and signal processing systems.
Gnu radio is both a python library and graphical front end for generating python radio programs. It can be used with external rf hardware to create software defined radios or without hardware in a simulation like environment. Gnu radio is a powerful software defined radio sdr tool for linux systems.
An elmer is a person who teaches and offers guidance to neophyte amateur radio operators.
Users create programs by dragging blocks onto a workspace and connecting block outputs into block inputs. Gnu radio is a powerful software defined radio sdr tool for linux systems. Gnu radio is a free open source software development toolkit that provides signal processing blocks to implement software radios. 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.
