[Elecraft] K2 power meter/wattmeter question

[Larry Phipps]

Mike, I wouldn't put much stock in any wattmeter, including Bird, at 10% 
of full scale.

To get a half scale reading between 0 and 10 watts (5 watts) on the Ten Tec  I have to set the K2's power level to over 8 watts.  If I set the K2's power level to 5 watts I get an indication on the Ten Tec meter that falls below a half scale reading between 0 and 10 watts.  In other words, appears to be less than 5 watts.
