[Elecraft] TX Gain

[Larry]

I am trying to do the tx  gain. I get the error code ERR TXG which says to
call tech support.
 
Just received this back from factory and added 100 watt and sun receiver. It
was said to have been all set to go.
 
Am I missing something ? Everything else seems ok.
 
Serial number 5185
 
The message report says
 
10.8 w
1.8 w
1.1 w
10 w
Elapse time: 13 sec
Tx Gain calibration failed because power reading did not converge to a
consistent value.
