I have run a lot of PSK on a K3/10. I have never had a problem running full power -- all 10-12 watts of it. Sometimes I type a lot too.
The K3, KX3, and the power amps are quite well protected, and designed to run full power in keydown modes.
I get good IMD reports. Don't worry. Be happy.
In a tutorial on clean signals to the NCCC last fall, K6XX noted that the distortion in solid state amps rises with output power, and that all Elecraft amps are significantly cleaner at half power.
Distortion also rises as power supply voltage drops. So a K3 running on 13.8 - 14.5 VDC will be cleaner than on 11 VDC.
