I've provided a spreadsheet that facilitates the calculations over a

So a couple of trips to the end of the cable are all that are required
to calibrate the setup.

(I must confess, I haven't tried this program with a line much over a
few inches in length to determine whether my calibration functions can
handle it, but I think so.)


That's a good idea!

Wes, does it collect enough information to be able to correctly
calculate a phase constant on longer feedline. Some work for the next
version perhaps?


No next version. I've got an n2pk analyzer now. Much easier to use,
at least over its frequency range.
