During the TAPR Digital Communications Conference, for 1-hour each day, attendees are invited to stand up and give a 5-minute Lightning Talk about any subject they wish, inside of Amateur Radio. These 12 segments are broken up into short videos for ease of watching. I hope you enjoy them, they contain subjects all across Amateur Radio.

This talk is from about the BITX40 QRP Radio from HF SIGNALS - http://www.hfsignals.com/index.php/bitx40/
