Just joined and here goes my newbie message. Sorry.

(1) I have an H4 from 2020 with the 0.5.0 FW version. I am guessing that an upgrade would be in order?
(2) Also looking into an "F" and saw some being sold on AliExpress for 102.93 marked down from $205.86 (50% off)
..is this a reliable source and product (link below) or, in not, what is reliable?

Thank you in advance.

Ali Express should be legit. But I have purchased a NanoVNA H4, TinySA and
TinySA Ultra as well as many other products from R & L Electronics. They
are legitimate and reliable and have great service.

Are you having problems. If it works all right, why bother changing. Yes, new models sure look good. Like Pro model of But if it works, don't fix it. If you mean firmware, there are so many basic NanoVna versions that I would not dare to touch any new firmware.

Have you tried measuring components. Vna is good for that, too. If you get good results, everything works?

I generally update the firmware whenever a newer version is available.
There have been some improvements made in some of the versions that were
worth having.

Gentlemen,

Thank you for the recommendations: if it works, don't fix it and last year's model/FW version works fine if it works fine.

Probably better my devoting my time to [re-]learning and using my H4 as is.

By the way, this seems like a very helpful group and tolerant of we beginners. I promise to scour the threads to as pick up the fruit -- either low-hanging or on the ground -- before plunging ahead.

Again, thank you!

A couple more notes:
1 - If your primary use of the nanoVNA is HF up to about 450MHz, then there is no need to buy a new model. I am still actively using my nanoVNA-H4 from 2020, and it is all I need for HF/VHF work. If you plan to use a vna at 900MHz and above, you do want to get a model that handles the higher frequencies better, such as the V2 models or liteVNA64.
2 - I also normally subscribe to the "if it ain't broke don't fix it" model - but the newer firmware for the H4 has extended its functionality quite dramatically. So after you have a good working relationship with your H4, if you want to have more functions to play with, do upgrade to the latest DiSlord release of firmware from here: (get the one with H4 in its name). And if you have not recently done a firmware upgrade on a device like this, you will need to make sure you have the correct driver installed, so please read the firmware update instructions in this group's wiki, and this document that I put together some time ago to make sure you have the correct driver:
/g/nanovna-users/files/Miscellaneous/DFU-mode%20Driver%20for%20Win10Win11

Stan,

thank you for the advice. As mentioned, I became familiar with the H4 one or two years ago (my past dims) and -- per your advice -- I did go ahead and upgrade from 0.5.0 to 1.2.4 and, my word, the features abound.

I guess my work is cut out for me inasmuch as the 1.2.40 display is loaded with features versus the old and lowly 0.5.00 release. Is there documentaiton and/or a menu structure map for this newer version?

Obliged!

I'm not aware of an updated menu structure map, nor of a consolidated description of features of the current 1.2.40 firmware.
Unfortunately, it takes a bunch of time and effort to create such documentation, so I'm not sure if anyone has donated such an effort.
You can look at the release notes for each of the versions to get the info (but that's a lot of release notes).
And there are lots of youtube videos that touch on one or more of the features. And lots of past messages in this forum, which you can search for a particular menu item you may be interested in.

Maybe someone else here is aware of good places to look...

look in files section, menuand notes by bruce dated 2024, good menu map and notes

Stan and Thomas..

Thank you! The menu is very helpful! Got a whole lot of learning to do, i'll be fun!

Wanted to add another "thank you" for posting that information. I've had nanoVNAs since they first emerged (2019?), and a ham friend recently gave me one dated from that era. Had never been updated, i.e. I had to dig through my boxes to locate a "grabber" to jumper the BOOT/VDD pins and enter the DFU mode. After I updated it to the latest DisLord firmware I began wondering if someone had compiled a current menu structure, and BINGO, I found it here.

To this day it still staggers me how inexpensive, powerful and useful these tiny nanoVNAs are. When I received my very first one I was so blown away after using it to test some filters that I rushed to order a second one, convinced that it was "too good to be true". Surely there must me some mistake for this capability to be had so cheaply, I thought(!).
