Low power out on 6 meters

Dave, G4AON

Mine gives very close to the expected power on 6m:

5W set, output 4.7W
50W set, output 52W
100W set, output 99W
120W set, output 119W

Measured on an LP100...

73 Dave, G4AON
K3/100 #80
------------------

After doing the full calibration multiple times (Synthesizer/Wattmeter/TX
Gain/ and TCXO) I find that I have lower than expected power output on 6m.
Firmware is 1.78 and I have the rig set to transmit through the 2.8 KHz
filter.

With the K3's power set to 100 watts I'm seeing 66.3 watts output to a dummy
load on my LP-100A wattmeter. Set to 120 watts I see a maximum of 76 watts.
Is this normal behavior?
