FT8 is fun and easy, but sometimes I miss just having a nice ragchew QSO. That's where JS8Call comes in.
JS8Call uses the same waveform and modulation as WSJT-x FT8, the same 15 second transmissions with time synchronization, and both have about 50 Hz bandwidths. However, as you will see, the transmission isn’t pre-programmed and encourages more personal chats.
