The problem I have with amazon for this is that you have absolutely no guarantee that you'll get a unit from any particular supplier -- they'll ship what they find convenient to ship, so you may get a good one, or you may end up with a clone. For some stuff it doesn't matter but I'd prefer to order from one of the recommended vendors;.

For whatever it's worth, I got mine from R&L.

That's not my experience - if you order something that is listed from the Aursinc store, you'll get one from Aursinc. Same with other stores on Amazon. But maybe this doesn't happen if an item isn't listed by a store.
But I also got my NanoVNA from R&L - they are a great business to support.

check out r and l electronics, u wont get a clone, and u can talk via phone if need be.

I second R&L for USA purchasers. They have a very good reputation. I purchased my Ultra from them. My original first run Tiny was purchased direct from Erik's supplier in the days before the vendor list. These days I prefer that all of my money go direct to the vendor rather than giving Amazon a cut. Some of the users in this group can advise on where to get the good VNAs. I got lucky and accidentally bought my early -H from the right eBay vendor before I learned about bad clones.

NanoVNA-H4 has a reliable touch screen. I have never had a problem with it. And no, there are no common 'bugs' not resolved.
It is a very nice device, with lots of features.

Hi Stan
Thank you very much for all this nice infos about nano vna H4 v3.1.
I will select a supplyer from amazon.de to have some advices from you and others ..

Thanks again

Hello Nizar,
Before you buy another NanoVNA, what brand of NanoVNA-F do you have Sysjoint or Deepelec?
Have you upgraded to the latest firmware?
If it is a Sysjoint, they no longer support the NanoVNA-F, but the Deepelec FW has been found to work on the Sysjoint unit OK.
You just need to be careful to flash the correct file from the download. The latest Deepelec FW is V1.0.5.
You should do a complete recalibration including the touchscreen calibration.
I have a Deepelec NanoVNA-F HW V3.1 (3 button) and the touch screen is very reliable.

Hi Bob

I have Deeplec Nano-VNA F 4.3'' V2.3 V3.1 FW 1.0.5 but very disappointed by touchscreen on the menu even with good calibration as shown on youtube video, very erratic and bugy , otherwise all is OK even -80db stable range . sweep points limited to 301 right now.
Wondering if it's a good deal to have an other Nano-VNA H4 V4.3 .
73's Nizar .

Hi Nizar,

I am surprised you are having touchscreen troubles with your Deepelec NanoVNA-F.
Try clearing your calibration data and do another touch screen calibration.
Leon changed the touchscreen cal points in the V1.0.5 FW to make it more responsive as some people were having problems getting a good cal previously.
Hopefully this is your problem.

As for buying a NanoVNA-H4, as I said, I am pretty sure the latest HW version uses a 4" IPS screen, so it should perform as well as the -F in sunlight.
The other plus is if you are into frequency references. Erik, the designer of the TinySA products, has written an alternative FW to turn the -H4 into an extremely sensitive Phase-Frequency comparator, the TinyPFA. The FW only works on the -H4, nothing else. You can swap between PFA and VNA capability simply by loading the appropriate FW.
BTW, the FW "update" process can be a bit overwhelming on the -H4 compared to the beautiful simplicity of the -F.
And last, but not least, between Hugen and DiSlord, the development of all the "bells and whistles" on the -H4 runs rings around the -F.

I love my Deepelec NanoVNA-F, but I am thinking seriously about buying an -H4. At the moment, I am torn between the -H4 (and TinyPFA capability) and the SAA-6 6GHz VNA also manufactured by Hugen and supported by DiSlord FW to get the extended frequency capability.

Why would you buy a clone when you can get the original for less?
