[Elecraft] [w2/K3] High SWR

Thanks for your insight on this.  I had no idea the SWR would be so high on
the G5RV although I was aware of these characteristics  in general.
I just did some checks across 20 meters and I get a SWR of 4 on the W2.  The
chart you sent indicates 2+ but not sure if I should expect that.  This is a
Full size G5RV at 45 feet feed with 31 feet of 450 ohm ladder line and about
90 feet of 50 ohm coax to shack.
With the new W2, first I wondered if it was working correctly.  I think it
is.  Second, is something wrong somewhere in my antenna system?  Looks like
the high SWR is to be expected except perhaps on 20M.  Does the SWR of 4
indicate a problem somewhere?
Lastly, about the power reading of the W2.  With power set at 5.0 on K2/K3
the W2 reads 8 and 10 respectively.  With power at 10.0 the W2 reads 15 and
17.  This seems like a lot of difference.  Could it be the K's are that much
out of calibration?  Is the W2 reading wrong?  What else?  Maybe the K's are
just creating a lot of energy!

Thanks for all your help on this.
