"The WSJT Modes, including FT8 and FT4, require a live operator" I am sorry to disagree, any "ROBOT" that you can buy on e-Bay, with your call sign, for $25 make the human operator 100% optional. Several DX entity become a cash cow for FT8 QSO/QSL confirmation money. Lots of reports of station 24/7 on FT8 for month. Just ask Joe. JC N4IS
