[Elecraft] K3 power calibration problem

[Alan Bloom]

I just installed the KRX3 and upgraded to the latest firmware (MCU 02.46
& DSP 01.92, from 02.10/01.81).  Now the power calibration is way off. 
Even adjusting CONFIG:WMTR LP and CONFIG:WMTR HP to the end of their
range (180) I can't get the power low enough.  For example, setting 75
watts gives about 100W output on an external wattmeter.  A 5W setting
gives about 7W output.

I'm almost certain this problem did not exist before I upgraded. 
Anybody have any ideas?
