Beware of cheap underperforming clones

As of 2023 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.

VNA_QT issue

N2MS 2023/02/01 17:03

I was able to connect to VNA_QT with my NanoVNA V2 Plus4. I recently tried and get this exception message. See attachment.

The NanoVNA V2 Plus4 with with NanoVNA Saver 0.5.4 and NanoVNA-APP..

The NanoVNA V2 Plus4 has software version 20220301.

Any ideas? I tried reinstalling the Cypress driver.

I use VNA_QT to upgrade the firmware, Is these another method of upgrading the firmware?

I wrote this late last night and messed up the grammar. Here are my questions:

I was able to connect to VNA_QT with my NanoVNA V2 Plus4. I recently tried it but VNA_QT detects the correct COM port but does not connect. I get this exception message. See attachment.

The NanoVNA V2 Plus4 works with the NanoVNA Saver 0.5.4 and NanoVNA-APP-1-1-213 applications.

The NanoVNA V2 Plus4 has software version 20220301.

Any ideas? I tried reinstalling the Cypress driver and it still does not connect
