It won't be long till dissidents are using FT8. Audio is dead. http://www.arrl.org/news/ft8-mode-is-latest-bright-shiny-obj...
VOA experimented successfully with using other MFSK modes that can be decoded asynchronously, quickly, and with fldigi, and its now a regular occurrence. https://voaradiogram.net/
I'm not suggesting JS8 is the ideal communication mode for dissidents, only that it's far better than FT8 for arbitrary text.
