I saw an message that made me think that there is a TDR function available for my NanoVNA-H v3.4

Can someone point me to this firmware?

The TDR function is in most versions of the firmware. It is implemented
using an FFT from the frequency scan, so it is a 'calculated' or
'simulated' TDR, with some related limitations.
There are several message threads in this group describing details of its
use - search for TDR or 'measure length'.

Use DiSlord's 1.0.45 in the forum's file section. There's a version for H and H4. Choose the correct vers for your device.?
