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.

Hi John it would appear the NanoVNA Saver software ,my Windows 10 64 bit laptop is flagging up warnings not to run as it may be harmful ,indeed windows defender antivirus is now scanning files for harmful files as I write 27% files scanned a wee while to go ,see if someone can provide answers to our queries ,I await with bated breath ,Dave 2E0DTB 73

Hi Dave & Dave 2E0DTB Thank you for email reply. I have now downloaded NanoVna-Saver

it is working OK, but I also had the problem

Ok Sigi thanks for reply ,guess I’ll have to wait for saver 3.8 thanks Sigi ,Dave 73

Hello David, if the screen flashes, it is something unusual. The Saver can be started without the NanoVNA connected. If it doesn't, there is some other problem. After connecting NanoVNA or V2 By pressing Rescan button  it will appear and you can Connect to it then after.

Hi ,tried your suggestion ,dam me Saver started without VNA connected ,then connected VNA and no flashing ,many thanks ,data validation switched OFF ,73 Dave certainly stable now 😊😊
