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

Mine is well within the 1/2 watt at 5 watts as stated in the specifications.
Measuring RF power at QRP levels is really not difficult. A low
forward-voltage drop
Mike,
The K2 internal RF metering is quite accurate - BUT it depend on having a
precise 50 ohm non-reactive load.
The wattmeters built into the KAT2, KPA100 and KAT100 remove the dependency
on a 50 ohm resistive load, but need to be properly calibrated first.
Many (IMHO most) external

The wattmeter in a basic K2 (without the KAT2 or KPA100) just measures the RF
voltage and computes the power. Therefore, the accuracy is highly dependent on
having an accurate 50 ohm

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

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
