ANd if you post a photo, someone might be able to ID it for you.

Anne, please browse the forum's Wiki.? There is alot of info there including the schematics for each revision of nanovna, H and H4.? There also photos of various boards.? On Thu., 8 Jul. 2021 at

Those are the debug pins. Look elsewhere for the UART port if you have one. May only be available on H4 version. Gary W9TD

I got brave and removed the cover. Now I am looking at PCB with absolutely no identification. Unauthorized clone or somebody not interested to advertise their work ? Opened the "git" link and was

Well, as always judged the source too soon in very few steps it asks to "create new document " unfortunately the folder has no clue what "document " is - there is no option to create document.

OK, I am too lazy to use commands to get "nanoVNA-saver" running. Anybody tried the attached procedure to run it as "standard" Linux / Ubuntu application ? Little long but seems accurate.

Use SimSmith.

Anne, Actually, I'm more interested in determining the matching range of a tuner with various antennas. I've used the AI1H method** of testing various tuners but that's a static resistance method.

Nice topics Barry just one small (nitpicking) remark on the wording in 3) Why does every feed line have an SWR of some value at some frequency? Actually it's not the feedline that has an SWR 'of some

My NanoVNA-H in the plastic housing (delivered in the black gift box with golden letters) has a big sticker on the back telling it has HW version 3.4 (this is the one with serial THT holes on the left

You may have turned off the calibration.? Go to the base menu, click calibrate and make sure the Apply button is checked.? On Wed., 7 Jul. 2021 at 7:44 p.m., Anne Ranch<anneranch2442@...>

Is this normal ? I have not checked my nano firmware version , got other "honey does" I am just curious , not panicking , not yet. On initial power -up I get splash of white screen then splash ,

Originally I did not see much benefits to put the nano into a box, however, after "reading the mail " here I see a "major" issue with the SMD coax connectors breaking off. So I am not after making it

On the newer -H boards (not H4, as DiSlord has shown) there is a simple set of 4 pads in a row with V+, Rx, Tx, and Gnd. This is eaxctly what's required to connect an HC-05/06/... Bluetooth module.

That isn't a problem with Linux.

I remember wbw a 100 foot piece of -48V 500 MCM being modeled as R+jinductance and C to trough. We were wondering what impulse it would take to raise -48V to 0. Turned out a disgruntled employee was

I did just that on my 2.8" nano but a better idea is to add a header and connect the BT dongle when needed. wrote:

Hello Dislord, Is it possible to install the HC-05 or HC-06 bent down inside the NanoVNA H4-casing? Or will that disturb the Nano? 73/SM6AYM
