Sorry, being new to posting on groups.io, I didn't include sufficient info to distinguish the specific version this structure map was made from.
As one of the posters answered, the map was created from the NanoVNA-H4 using DiSlord's release version 1.0.45. Next time, I'll be a bit more careful when posting. Also, too bad there is a way to edit posts so corrections can be made...
