Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Nano VNA V2 2_2 Touch screen rotated 180 degrees on startup after 20201013 firmware update?

As the subject line states. I purchased a Nano VNA v2 10KHz-3GHz from Ebay. I have no functional issues with the unit. The unit came with ver 2_2 firmware dated March 2020. I updated the firmware to the 20201013 version which works well but I have a problem now with the touch screen being 180 degrees rotated on power up. I can use the buttons to recal the touch screen and all is well again but Is there something I can set to fix this power up screen problem, TIA

I don't see it as a problem, Mitch.
I have used the 'flip screen' menu option deliberately to have the
connectors at the top.
More ergonomic IMHO.

The screen itself isn't flipped. It's the touch panel over the display. I have to recal it every power up, the regular screen is right side up..
