[Elecraft] K1 output power msmt accuracy

[Phil Wheeler]

BTW, Mark ..

I just checked the specs on the WM-2 at the website and it is 5% of full 
scale.  Given that you are likely using the 10 W scale of the WM-2, that 
is a 0.5 W possible absolute error.

And the K1 wattmeter will not be perfect, either.  So finding that the 
WM-2 and the K1 differ by 0.5 W is not a bit surprising.
