All,

Where can I find the instructions on upgrading to the latest firmware version for the -F model and what is the latest version? Thanks in advance...

Hello,
NanoVNA-F has it's own groups.io and after-sale support~
You can visit groups wiki to get what you want: /g/nanovna-f/wiki/How-do-I-upgrade-the-firmware

v0.1.4 2020-03-26 : This update requires recalibration of the device
1) Supports 0dBm output (fundamental frequency, for HW V3.1 & HW V2.3 only, for HW V2.2 still -13dBm output);
2) No new features were added compared to firmware v0.1.1.

v0.1.0&v0.1.1 2020-02-03 : This update requires recalibration of the device
1) Add TDR feature;
2) Add marker tracking feature & dynamic update of frequency and other information when the mark moves;
3) Add ordinate display
4) Support to 10kHz frequency
5) Some font, color, and layout optimizations
6) Suggestions from groups.io/nanovna-f & facebook group members and much more, thank you for your feedback

=====================================================
DISPLAY->TRANSFORM

From there you have to choose one of the step functions (see various user manuals). Works the same as on on NanoVNA.
