JS8 is I believe and confirmed with this video link () is an evolution of FT8 and is my next go to as I prefer to have a conversation rather than the robotic qso’s of FT8.
However I do like FT8 almost as a test program in order to to prove how far you can be heard with the least amount of power on different antennas particularly when operating /P as I do quite a lot. Its also a quiet mode when away in the motorhome and I want to play radio early in a morning while the xyl is still sleeping.
I have put the sbitx through its paces in a digital contest and it failed on me when I tried to use PSK/RTTY with FLDIGI so had to make do with only FT8 but managed a creditable
3rd place in the WAB digital contest earlier in year.
The confusing thing now with PSK is that there are many different flavours of it so difficult to pick out which flavour is being used, that may be why FT8/FT4 have taken off as they have. I do still hear RTTY on the bands so thats another possibility too. Need to find a Linux based alternative to FLDIGI I think for other digital modes and thats where I think JS8Call fits the bill as an alternative keyboard based communications mode to have real conversations digitally?
