Not just the tuner, the K3 is not rated for full power on 100% duty cycle modes. Just like it's not rated or 100% key down CW. But realize that many of the modes are half transmit and half listen.
Different digital modes have different duty cycles. From the W1HKJ.com website: 100% duty cycle: Olivia, MFSK,RTTY 80%: BPSK, MT63 44% CW 22%:FieldHell There are more modes on Dave's website, but those are some of the major ones. IDK if Joe Taylor has similar information on his website for the modes he supports. It loioks like his modes may require full duty cycle.
