My K3 exhibits the same problem on 20M. I have to reduce power down to 90W to run without the Hi Current warning with an antenna match of 1.1:1. All other bands, no problem. I upgraded from a 30A switcher to a 35A linear supply to see if that helped and there was no appreciable difference. I do run my station power through a RigRunner for power distribution. I am considering building a properly fused cable and trying a direct connection to the power supply, although the voltage sag on key down appears to be only about 0.8VDC.
