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.

NanoVNA V2+4 CW Output

Mike Wyatt 2020/12/06 13:49

I've noticed the V2+4 version is pulsed CW, while the SAA-2N version is continuous when using CW output. Both are running the same 20201013-32077fd firmware. Anyone know why the V2+4 version has a pulsed CW output rather than the desired continuous CW output of the SAA-2N, while both are utilizing the same firmware? This makes the V2+4 version basically useless for use as a signal generator!!

Thought the 20201013-32077fd was the latest firmware?

I've downloaded the 20201122 from GitHub which seems to be the latest firmware but not sure how to proceed since I don't see a file like the nanovna-v2-20201013-v2plus4.bin which is presently loaded version on the VNA. I reloaded the 20201013 firmware to check and see if this corrected the CW mode, it didn't since it's the same firmware as when the VNA was received. Did the firmware reload per the instructions from NanoVNA-QT.

I'm sure I'm missing something, any help is greatly appreciated,

Edited. Looks as if the latest version 20201122 is not available as a latest release yet from GitHub. It must be complied and such, and more of a software developers version, than a direct download dummies verison for folks like me :<(

Guess I'll need to wait for the direct downloadable version.

I asked HCXQ (OEM for V2+4) and they indicated the "newer" firmware has some "bugs" and the latest is 20201013 which is what I have. Think I'll wait until the "new" firmware is less "buggy" and available.
