I am still puzzling thru this. On page 3:
"As seen the trace is not flowing the circumference off the Smithchart
which must spiral inwards in a progressive way."
.. evidently "flowing" should be "following" and "off the Smithchart"
should be "of the Smith chart".
I >>guess<<: " which must spiral inwards in a progressive way" should
be understood "but is spiraling inwards", e.g.
"Instead of following the Smith chart circumference, the trace is seen
spiraling inward."
.. where this trace is from an unterminated non-ideal cable (not airline),
and changing (50 Ohm) LOAD shunt capacitance value C from 51.8 to
-108.2 improves "calibration".
