100% FT8 basics, don’t turn it up to 11 and hope for the best. Likely result is transmitting splatter across the passband, worsening your reception reports and causing a nuisance. My advice is to turn radio transmit power to 100%, turn PC volume to 0%, and WSJT-X slider to 100%. Call CQ at 1500Hz offset. Turn up PC volume until radio’s RF output meter reads whatever max power you want to transmit, eg 50W. Then, whatever you do in WSJT-X, you can never over drive the radio and splatter. Takes the ALC question out of the equation, there’s no need for it.
