Let's be civilized and please do not tell me how serious I should be. If it is NOT OK to asks here , please say so. I am in "let's get to know nanoVNA " mode . I cannot possibly know where to start so

Mike, go through the forum wiki - there is a note about using 75 ohm modified firmware that will work on any of the original? and H nanos (not the H4). The firmware is in the files section.

Saw this the other day on Instructables — note that it talks about NanoVNA, etc. Seems like this could be adapted with some code changes to a general purpose auto antenna tuner:

I recently started a thread about using the NanoVna on 75 ohm TV antennas. I haven't found any success with a simple 50 ohm and 100 ohm resistor. I Have tried just a connector adapter and a 50 to 75

To get a good idea how antennas behave check out 4NEC2 an antenna modeling program. It can be downloaded from the net free. There are other programs as well like EZNEC that might be easier to start

I'm not explaining this well. Goal: understand more about how an antenna works using a Nano VNA tool in S11 mode Translation: understand the graphs of R, X and Z vs. frequency that I get with Nano VNA

Rig runner makes a circuit board that can be used for building your own tuner or other projects that require an analyzer. It's called "RigExpert Antenna Analyzers AA-30ZERO". This might be what you

SWDIO and SWCLK are the standard designations for the GPIO pins on STM devices. You seriously need to read up on these devices first.

The tutorial describes how you can write your own python program, I suspect you do not want this. The easy way: - Download the zip from github

This is the last version (3.4) of the original NanoVNA-H with the 2.8 inch display.? /g/nanovna-users/photo/0/34671.21928.0?p=Created,,,20,2,100,0 Folks - browse the forum's Photo

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.
