In this video from Ham Radio Now's YouTube channel, John Ronan EI7IG gives a talk in the USA about methods of sending rapid messages during emergency communications scenarios using D-STAR. John is a leading light in Ireland behind AREN - Amateur Radio Emergency Networks - which is a cause close to my heart. A northeast region AREN group was set up a few years ago and is co-ordinated by Tony Allen EI4DIB. The purpose of AREN, for those of you who are not involved in amateur radio, is to provide communications or help with communications during disasters or emergencies. AREN groups have also assisted with comms at community events.
