Amateur radio digital comms for emergencies has both benefits and disadvantages. I like the way JS8 and Olivia deliver error free text. I prefer Olivia bcz it is not bound to time slices. I don't always understand voices on SSB, but I can still read text on the screen. Digital adds several layers of complexity. If a computer is involved, when things stop working, it can take hours or days to troubleshoot and resolve. An anecdote, a local team and I were setting up and testing an amateur radio network using a digital mode. Right in middle of teams involvement, Microsoft decided to update my O/S. Well, you say, that could have been avoided ---. In that era, perhaps not, but the point is it did happen, my digital comm system was down for the count, it was a major hours long upgrade from Msoft. Even when O/S is working well, configurations to sound devices and levels have a way of becoming unconfigured. Not every operator at an emergency comm station up to immediately fixing the problem . First priority at the emergency comm station is Reliability/Resiliency. So, my fellow hams, like the president said in the movie 'Mars Attacks', "Why can't we all... just... get along?" After which, of course, the Martians zapped him.
