FT8 and the FTDX101MP, does ALC matter? Part 3 - KJ7E 

Well done for making the video, so many people have this wrong. The compact radios won't thank you for operating full power on FT8 but the adult sized ones with big heatsinks and fans can usually be ragged hard on FT8 without the transmit spectrum deteriorating. Of course the thermal cycling of the PAs is still a fatigue factor. In one of my rigs however feeding Transmit audio in via a rear panel socket could overload circuits PRIOR to the mic gain control. Controversially it might be interesting to see that you could turn the PA bias current down for cooler running on FT8 without affecting the transmit signal. 73
