R: RE : [Elecraft] KX1 says "PO.4" -- is this 0.4 W or 4 W?

IMHO you can try with a bolometer, wich is a milliwatt-meter, an some good
attenuators capable of handle the power levels that you are going to use...
An HP432A is a good instrument that you often find on ebay for less than
200,00 USD (thermistor head included).
If You are going to do some serious test this is the right way to do it!
Alternative: find a dear OM near you that operates on microwave (1296 MHz
and up).... He has the instrument for sure....

I was afraid of that -- I recalibrated the tuner with a 50 ohm dummy load
and now it's showing 1.9 W when running on batteries, which sounds correct.
I will further calibrate when I have access to a known accurate wattmeter.

Thank you for clarifying.
