Ken,
As delivered, the NanoVNA default calibration, Location 0, is apparently set up with the S11 reference plane at the on-board connector. You can run another calibration at the end of your cable put that in another storage location if you like.

Am I missing something big here? Does this nanovna calibrate the end of the

Recalling cal 0, with the TX connector open, it looks like an open. If I do a
complete calibration at the end of the cable, then leave it open at the end,
it is not an open, at any frequency. What am I doing wrong?
