Hi All

I just have my New Nano-VNA-H4 from SEESII , i calibrate it on different spans and empty memory's, all seems working fine, but it does not save the latest recalled calibration memory , at startup it always open the first recall calibration, is this normal ?, How to save the latest recalled calibration for next startup .

Nizar, memory slot 0 is always used at startup. Just save whatever you want to start up with into slot 0.

Hi Stan

Thank you, i read firmware version 1.2.27 already installed on my new H4 , did I need to upgrade it for newer version ??

Thanks , 73's Nizar .

V1.2.27 is an excellent firmware version, so you are good with it. There are newer versions which add some features. You can read the release notes to see if any of these are important for your use cases, but I suspect you would never notice the difference in most of your use.

By default at startup always load 0 calibration slot
But if select config->expert settings->remember state (and save config, config->save) NanoVNA store several settings in backup registers and use it on startup (include used calibration slot)

Hi Dislord

Thank you very much, version 1.2.40 already installed and tested : works great as expected , Really advanced functions .
saving latest memory slot also tested and it work OK.

Thanks , 73's Nizar.
