[Elecraft] K3 Transmitter Gain Cal Failure at 1mW with KXV3a

[N2ZDB at aol.com]

Hello K3 Support,
 
I installed the KXV3a tonight into my K3 and when I went to do the 
Gain Calibration it failed on 6 Meters as it was unable to get the required 
 output.
 
Any idea why this output could be low on this band (I believe it only  
reached an 8 out of the expected 10)?
 
Thank you,
