Based on a presentation by Eric at the West Valley Amateur Radio Association, Elecraft tends to build their equipment to run at full advertised power with digital modes. Their model is a RTTY contester calling CQ with 60% to 70% of the time transmitting. He indicated that the KPA1500 would run for 5 minutes at full output before needing a rest.

I have not had any problems running my K3 at 100W with FT8. Interestingly, the fans speed up during the receive part of the cycle.

Don't Elecraft recommend using lower power for high duty digital modes?
(Though FT8 us 15s bursts so not as high duty as some).
