Probably JS8Call instead. It's an FT8 fork that allows for arbitrary text. Worth checking out.

It'll take a ridiculously loooooong time for them to even say "CHINA BAD. HK GOOD. DON'T BELIEVE TV."

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/

That message would take about one minute to send. But it could be sent with very low power and received well below the noise floor.

I'm not suggesting JS8 is the ideal communication mode for dissidents, only that it's far better than FT8 for arbitrary text.
