I mean specifically selecting the mode they call DIGITAL (not SSB or RTTY for digital). This mode has a "PSK" and "OTHERS" setting, but the manual (if I remember correctly) only has some sample setup for PSK. I'm wondering what "others" it might support. Also, any more info on how this mode works would be helpful. Like it seems like it wants to isolate a specific carrier tone and so probably won't work for things like FT8 and JS8 unless maybe you narrowed it to a very narrow range with filters or something?
