My nanovna-H4 with 0.5.0 firmware does have a way of entering a velocity

The horizontal axis is calibrated in nanoseconds, and that does not get

by the velocity factor.
Jerry, when you turn the 'transform' on, the marker value display at the top right of the screen (the one in white, labeled "1:"), reads in both nsec and mm or meters, so you can read the adjusted/measured length directly there, which already accounts for the round-trip time. The length value is adjusted based on the VelocityFactor you set. It is a little weird to set, you have to type the velocity factor as a percentage (e.g. 66 or 84) and press the x1.
