There's a lot of information here and I appreciate everyone's input- I reset and recalibrated the nanovna after finishing up the test rig according to Dave's build, i missed the copper tape on the

Success! 1. Shorted BOOTP and VDD pins 2. Connected USB-C to PC (MacBook Pro 2016) 3. Started STM32CubeProgrammer 4. Loaded latest NanoVNA .HEX file 5. Started Download 6. Success! NanoVNA working as

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

I called R&L electronics today. They're going to replace the unit. A+ service from R&L.

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,

Since you are dealing with SM inductors, I remembered something I've learned and practiced for a couple of decades. In mounting SM inductors it matters how they are constructed internally. The

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

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

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. Zack W9SZ [email protected]> wrote:

Are you having problems. If it works all right, why bother changing. Yes, new models sure look good. Like Pro model of https://www.tindie.com/products/hcxqsgroup/nanovna-v2-plus4/ But if it

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

Yeah, I've been thinking about that...although I will note that the laptop was NOT plugged into the AC adapter when I made the two measurements. What I'll try on my next visit will be to leave the

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

I would calibrate the NanoVNA again with binding posts. I would use something like 30MHz-100MHz, 900MHz is surely too much. (Like others have said.) When the Vna asks "open" I would leave the

Hello To perform this type of measurement, I use two BNC sockets bolted to a printed circuit board. I solder the components. This way, I can create a shunt or a series connection. I connect the SOL

Roger, The only thing I can think of right now, may be in relation with the fact even though I ordered my inductor / capacitor design kit for RF, the test frequency of the inductors is 100MHz. The

Roger, Thanks for the idea. I already tried sending them an email a while ago for that exact request ! The phone is still ringing, nobody answered yet at the other end ;( But I should throw the
