G+_Jason Perry Posted March 17, 2018 Share Posted March 17, 2018 Has anyone seen a portable device that will capture a chunk of RF when triggered. I want to press a button and capture 30 seconds before and after the press. I am thinking of pulling out my RTL-SDR and ordering another Pi to start playing, GNUradio should be able to pull it off?
