[Elecraft] K2 power meter/wattmeter question

[Mike Monger]

Hi Fellow Elecrafters,

How accurate have you found the internal power meter/wattmeter to be on the K2??? 

I ask this because there is a large difference between what I set the power for, on the K2, and what it displays  as compared to the external meter (contained in a Ten Tec tuner, scale 0 to 200 watts, first division being between 0 and 10 watts).  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.

I tend to want to trust the Ten Tec meter a bit more, since it has always given me a good indication while running powers up to 200 w and in accordance of what the power out was in a particular rig.

Anyway, any comments would be appreciated.  And, (maybe) should I just purchase a good QRP wattmeter kit or invest in a Bird/Byrd.

Thanks In Advance,

Mike
