[Elecraft] [K3] problem with Transmitter Gain Calibration

I've had this happen several times after the output power disappeared.

It appears to be that the RF ground return to the output connector is completed through the "2D" block at the upper rear of the K3 (as viewed from the front.)  

If I'm wrong about this I'm sure a response will be forthcoming, but my experience has been that loosening the screw(s) and "scrubbing" the interface to the output board (no ATU in my K3) and retightening will fix the problem.  Until calling the next DX station that I need for a new one, that is.

Problem: 

  

The transmitter gain will not calibrate.  Receive an error code: 

  

Starting 5 watt calibration 

Calibrating at 1.900 MHz 

Calibration power settled at " 0.0 W ;" 

Elapsed time: 6 seconds 

Tx Gain calibration failed because transmit power did not reach the expected value 

5 watt calibration failed 

    

Radio is a new build.  Checking out at low power.  Installed the 100 watt power amplifier, then removed the amplifier to test at low power per book instructions.  I have reinstalled the PA jumper block for all test runs.  

  

The radio will not receive Hz filter and it is properly configured. 

  

Is there anything else I need to do to get back to low power configuration?
