FT8Call is a derivative of the WSJT-X application, restructured and redesigned for keyboard-to-keyboard message passing. It is not supported by nor endorsed by the WSJT-X development group. FT8, as we know, has dominated the airwaves for over a year now. Imagine the ability to have keyboard to keyboard rag chew, with the same exact performance of FT8. Why wouldnt you? This is brand new, still under development, and will surely take off big time!
