I just replaced my 'back up shack' antenna today (it was a 45/90 OCF
experiment) with a 138' open wire fed doublet. The center is up 50' and
the elements are more-or-less installed. They will get more installed
later.
I used the 'Ladder-Snap' pieces to make the feedline. In 35
Not an Elecraft ATU? Well, there's the problem :-)
More seriously, perhaps your tuner does not like
what it is seeing.

Well, I see how his dipole might be presenting an extreme value of
impedance on 20, depending on the length and impedance of the line.
But why is his dummy load weird only on 20M? That's a puzzle -- and it
needs to be solved first.

It sounds like something may be amiss in the K2
for 20m; not sure how or what. But it may be the
SGC is getting to 1.5:1 on 20 also -- since the K2
seems to be reading 1.8:1 for a dummy load which
is 1.0:1 we can assume.
Do you have another rig you can test this with --
or maybe a meter
Steve,
Yes, the weather has been great here in the Triangle area.
Generally OCF dipoles can generate a lot of common mode RF and bring it
into the shack unless measures are taken to kill that aspect.
However, your results on 20 meters with the dummy load do deserve a lot
of careful
In the sentence below: Replace CAL P with CAL PWR to be correct.

If you were using CAL P, the L and C solution for 20 meters was still
present, but the display during a TUNE would show the power
