[Elecraft] W2problems

[Alan Grant]

I feel that I have a problem with my W2, when I connect the directional
coupler to my K3/100 s/n 05779, it indicates what I think is the correct
SWR and Power out, swr 1.1 to 1.2, then the atu brings it back to 1.0
however, when I connect the directional coupler to the output of my KPA500
the W2 shows the SWR as nearly maximum, and the forward power of 20-30
watts; however the SWR indication on the KPA500 shows 

only about 1 to 2 SWR leds and the output around 300 watts.

I would have thought that having the coupler rated at 2kw it should be
connected to the output of the Amplifier.

Have I thought wrong again, because what is the point of the W2 only
showing the output references of the K3/100.

When I have the W2 connected to the K3/100 and the KPA500 in the operating
mode the SWR shown on the KPA500 is about2;1 and I am not happy for it
being that high, I don't want to hurt my new toys.

I would like to know the correct way to connect the W2 so I am sure of the
"Correct" Swr 

Hoping that someone can enlighten me
