I find the jog wheel quite useful for moving the marker. Alternatively you
can use the Search Minimum function in the menu to find minimum SWR point
in the tracing.
I have not opened the casing for fear of damaging it! Even now, there is
some loose contact somewhere: Sometimes when I switch on, the screen is
blank. Switch off and switch on, the screen comes up well.

I have a NanoVNA (2.8" screen) from about 2020. Overall it works well, but
the Jog Switch doesn't do anything.
The touch screen works fine, it calibrates OK and measures SWR with
ease... but the jog switch doesn't do anything. Should it do anything?
Firmware is reasonably current with version 1.2.43 (p: 101 IF: 12k, ADC:

Am I missing anything by just using it via touch screen? An inquiring
mind wants to know!
