Please excuse my 80yr old brain, I know to include the rest of the info. but didn't type it.
I have a NanoVNA H4 with FW version 1.2.40.
My question is;
Is 1.2.40 the latest FW or is there a newer version?
The reason for my question is the "Calibration correction" does not show on the menu selections on my version of FW.
Thank you in advance.
