[Elecraft] KAT500 VFWD reading in watts

[Don Wilhelm]

Don,

I don't know the exact formula, but I can say that the power is 
proportional to the voltage squared.
If you really want to do that, I would suggest that you set the power to 
several different levels and compare the square of the VFWD to the power 
output - see what the common factor is and use that - or make a graph.

If you have the KPA500, I would thnk determining the power out is even 
easier - the KPA500 displays the power, and that will be correct *if* 
the SWR is low.
