There were 12 of these Lightning Talks during the 2019 TAPR Digital Communications Conference.  These talks are open to anyone in attendance and are supposed to be 5-minute talks about anything in Amateur Radio that you want to present.  Most of these videos are around 4-7 minutes long, so I decided to put them all into 1 post on this site.  They are also available inside of the YouTube Playlist for the TAPR DCC 2019
