Create Your Own Open-Source Software-Defined Radio

This video helps you build a budget Software-Defined Radio, all software free and open-source, with a single inexpensive component as the wideband radio-frequency front end, able to tune from 500 KHz to 1.7 GHz. Included is a tutorial that explains how radio modulation schemes work -- CW, AM, SSB, FM and wide FM. Also included are full instructions for a test transmitter written in three forms -- Python, Rust, and GnuRadio flowchart, all with source files, all free and open-source.
