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?
