The first, more suited to a younger audience, features Phil M0DNY being interviewed by David G7URP at the RSGB Convention. It lasts for just under 9 minutes and can be found at this link: https://youtu.be/78Bt0aIJXQg?t=1935
The second longer video (42 minutes) is entitled "Digital ATV - Opening New Horizons" and can be found at this link https://www.youtube.com/watch?v=oUoGvXYoY0Y. This is the talk that I gave at the RSGB Convention that explains how much progress we have made since the days of 70cm AM ATV and what the hobby has to offer now.
Please consider whether you could use at least some extracts from these videos for talks at your local radio club.
