Actually wanted to wait for the stable release but couldn't resist. However, FT4 seems not that populair yet. I listened several bands but there was only activity on 20m. It is evident that you need your computer accurately on time and it is less sensitive compared to FT8. However, I made some DX...
Now I'm curious....will this mode replace FT8? Will it replace RTTY in contests?
Only the future will tell...
