[Elecraft] KPA3 Fails Calibration

[Bruce W1UJR]

Hello all,

Just installed the KPA3 100 watt PA into my K3.
While running through the TX Gain Calibration program in the K3 Utility I received an error.

Did the 5 watt cal no problem, but when it was doing the 50 MHz calibrate the K3 shut off
and displayed the error below in the K3 Utility window.

Thinking this an aberration, I attempted 3 more times, each time the K3 shuts off during
the 50 MHZ cal period.

I used my nifty Elecraft W1 power meter to measure RF, on all bands 50+ watts, the 5/6 LEDs on the W1
were present on all bands, including 50 MHZ, as the K3 Utility runs the RF test on the 50 MHz,
the K3 shuts off. 

I just upgraded to the new firmware before adding the KPA3, not sure if this is related to that
or not.

Suggestions?
