[Elecraft] W2problems

[Ron D'Eau Claire]

Alan, do you have the coupler oriented correctly with the "TRANSMITTER" end
connected to the KPA500 and the "LOAD" connected to the antenna. It sounds
like you have it backwards so the W2 is reading the "reflected" power as
"forward" (20-30 watts) and the "forward" power as "reflected" which would
trigger a huge SWR reading.  

You are right about the hookup: the directional coupler should at the output
of the KPA500.

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
