K2 power out accurate? (UPDATE/CLARIFICATION)

Evening All,

I neglected to mention this one piece of information with my issue on the K2/10.  The pinning of my Wattmeter happens when I have the K2 connected to my outside antenna in this order: K2 to Wattmeter to outside antenna.  This is after I do a tune and get a low SWR.  My K2 DOES have the KAT2 tuner installed.  My antenna is a simple G5RV Jr.  I originally said that I had it connected to a dummy load and that was happening.  Sorry about that.

I did connect the K2 to my Wattmeter, and then to my Dummy Load,  and power output was within a Watt or so on different power settings.  So, that tells me the Wattmeter is calibrated within tolerances and the power out appears to be accurate.  I also verified this with my other HF radios, both kit AND commercially produced.

Still, I wonder what would cause my Wattmeter to be pinned at 5W when transmitting into an actual antenna?

The Wattmeter is the QRP Wattmeter from Oak Hills Research, and the 100 W dummy load is from them as well.

73,
