rtl-fm is a set of scripts that acts as a wrapper for rtl_fm and a few helper scripts for making listening to radio signals with SDR easy. For usage and available options see each script's 'usage' section. In addition to the wrapper and helper scripts the project includes 'node-red' based control panel that allows operating SDR dongles with the browser from everywhere. The dashboard is under development but works fine and it uses rtl-fm behind the scenes.
