This directory contains simple but functional receiver examples implemented using the GNU Radio Companion. Before you execute any of the scripts you should check the USRP and audio settings to ensure that they are compatible with your hardware. The xyz_rec.grc and xyz_play.grc files are special editions of the receivers that I have used for recording and playback of the received spectrum. More description and video demos are avaialble at http://www.oz9aec.net/index.php/gnu-radio/grc-examples Alex OZ9AEC
