Problem with 100W PA

[N1IX-2]

I noticed that my power output would not go above 80 watts on the display so I finally decided run the "Calibrate Transmitter Gain" selection in the K3 utility program.
The 5 watt calibration runs fine with no problem. When I run the 50 watt calibration I get a number of errors. The first is "CheckSwr: Unexpected response "" to "DS;" State 151.
Which is followed by a number of error messages.
Now the K3 trips off whenever I try to use more than 40 watts.
I have tried everything that I can think of.
Both antenna connectors
Two different dummy loads.
Different cables both RS232 and Coax.
Powercycle the K3.
Even rebooting the computer.
Has anyone else experienced this? Any suggestions?

I think I tracked the problem to a bad powerpole connection at the power
supply. Anyway, It is working now.
Sorry Ed I was just about to give it to you:-)
