Here is a link to a collection of screen shot videos of digital comms at HF. I think all are on 80 meters using Olivia 8/500 and MT63-1000. There are also some tutorial videos. This is all using W1HKJ’s software. (By the way, he lives in one of the towns hit hard by the tornadoes earlier this week. The funnel just skipped by his neighborhood.)
