Is the NooElec nanoVNA any good?
They have a nice bundle on sale and I'm so tempted.

Yep. I bought one. It came with an older firmware and no battery voltage diode. The battery doesn't have a connector, so adding the diode is easier. It arrived well packed, and has worked great. You'll definitely want to upgrade the firmware when you get it. There have been some nice adds in recent versions.

I agree. I bought one too and my experience was the same.

Thanks to jwd270 and Joe St. Clair AF5MH, I placed my order an hour ago, I've downloaded the lastest firmware and will look into adding the battery voltage diode.
I expect to use mine with a netbook most of the time.

Sound like NooElec is selling an older version board. Anyone know what is the version number of the PCB? (3.1? latest is 3.3) Is this a NanoVNA-H or a clone?

Roger,
According to hugen, "Looking at the images shared by the group users, the version sold by Nooelec should be the version I sold in September. I don't know where they bought the version and sold it, but it was made by me."

This is from message number #6802.

I think it's 3.1 based on the "V3.1" that appears under the battery. This one was purchased directly from nooelec on 10/12/2019.

I don't know what the differences are between versions, nor am I aware that I should care, nor would I know how to determine which version a seller has in stock, nor would I think it fair to the seller to return a product for being the wrong version of a product that has no version control process.

First of all, I am a total newbie. I ordered in the blind, only looking for the "NanoVNA" word or label:


This particular package had the added cabling, which was of interest to me. My needs are minimal; -At this point, I only have an interest in sweeping my HF ham antennas.

Question: As in the RS-918 (SDR) and related, the firmware "is the radio," and so I am assuming that this might possibly be true with this unit as well. (Look me up in QRZ.COM for more info: ) There is a LOT to learn and digest with the NanoVNA, and I am not there yet. Will the (or ANY) NanoVNA be upgrade-able to some common point or ability? -Or, have I purchased a limited device?

I was unable to locate a source that mentioned "hugen." Apparently, this is the best source of this fine unit. What is the URL for the better source, or is it worthwhile for me, as a low-end user?

Thank you from Mike, K0JTA

The unit can operate as a stand-alone, unlike the many SDRs out there.
However, it can also operate with a PC, laptop, Android, and a number of
other platforms. With PC support, you get a MUCH larger screen, but PC is
not required for complete operation. You don't really need a PC if you can
read the small print on the color display.

The FW is continually being upgraded and additional functionality is being
augmented on a regular basis.

I'd suggest, as a newbie, you read some of the previously referenced
tutorials on the uses and capabilities of a VNA. It goes well beyond just
sweeping antennas for SWR. A VNA is an EXTREMELY capable instrument for
measurement of RF parameters of many flavors. I'd strongly recommend you
read the Agilent tutorials previously referenced on this group, I think
last week. Check the archives.

What is pictured there is missing the "CH0" on the bezel. I think hugen would tag that as a clone That said, I have not seen where the clones have been shown to perform any worse. All NanoVNAs can be updated with a choice of new firmware with larger font, TDR, extended marker functions, etc.

Looking again at your pic from Amazon, I notice it is sold by KKMoon. I brought two NanoVNAs from this same seller there. When they arrived one was a clone and the other appears to be a hugen original. You really can't tell what you're actually going to get from looking at the pictures in the adds.

Many have measured and tested it but found no noticeable difference between the variants. Probably the raw material comes from the same source, pcb is the same. So why would it differ unless the quality was properly controlled. They make sure that there is a slight difference between what they make and what they are compared to what is produced at the neighboring plant.

The 'H' on a NanoVNA-H supposedly means it is a Hugen device. Is there anything keeping the cloners from labeling their devices as -H ?

=================================================================

On eBay I already see cloner's misrepresenting their units as NanoVNA-F's when the photos are obviously 2,8" NanoVNA's. The same thing will happen with the Nanovna-H, and buyer's will have to be knowledgeable that the -H has a protective case and comes in a specially designed box with accessories.

Down the road the case designed and packaging will probably be cloned, but by that time hugen will hopefully stay ahead of the field with NanoVNA-F V2.

I suppose that in theory tagging NanoVNA-H with a trademark ? superscript might help but I don't know if that would help on eBay.
