Exploring the Spectrum: SRD Garage Door Keyfob
In this video we demonstrate what happens when you press a button on a garage door keyfob. It transmits a signal at 433.9MHz, which can be received by the RTL-SDR, and viewed in Simulink!
We invite you to view more at http://www.desktopSDR.com, where you are able to download a free copy of the book and its support files.
