[Elecraft] Tx Gain Cal failed

[aj4tf]

Hello,
New build,  K3S s/n 10669.
Everything went well, but when I got to the TX Gain calibration (low
power) something isn't quite right.

Using the K3 Utility (ver. 1.15.6.27),  the utility says that the
"power won't settle" and won't get past the 160m band.  Watching it,
the displayed power value fluctuates around 5.0 W.

You can see it in this video:

Manually setting the band, and doing the tune at 5W setpoint shows pretty
much
the same thing on every band ... the displayed power 'hunts'
around 5W.  The power measured at the external power meter, however,
does not seem to be moving, it is pretty stable.  
Reported SWR is 1.1 : 1.  This radio does not have the KAT3 in it.

The 100W amp is not yet installed.

Firmware: MCU 5.38;  FPF 1.25;  DSP 2.86

Any advice would be appreciated.

Thank you,
David  AJ4TF
