[Elecraft] K3 Output power difference

I recently loaded beta ver. 2.80 and all seems well -except-
there now appears to be a power output vs. power indicated
difference of about 10W on all bands, including 6M.  

Setting the radio at 100W on the display delivers 110-115 
watts output as indicated on two Bird wattmeters that I have 
confidence in. There are two Birds involved ... one in the 160-10 
antenna #1 output and another in the antenna #2 output.  Both 
agree when swapped between the outputs.  Readings were 
taken while transmitting CW key-down into a 50 ohm dummy 
load.  A second load was substituted for confirmation, BTW.

I've run the TX calibration routine in the K3 utility program
with no change.

I recall reading posts abut this issue recently, but no longer
have them available.

Anyone else observe this difference after loading 2.80?
