I am with Dragan - I found an article that lacked a complete history and what was there was incorrect. I tried to get it corrected and expanded, but I guess the original author had more clout so all

Asuming you can physically measure the length of the cable or you can cut a smaller length of the cable. This is my way to find the velocity factor using Dislords fw: Measure the length of the cable.

I bought a NanoVNA H-4 and found it good (for my own use). I drew the MENUmap soft.ver. 1.1.01, when the right kind was not found on the Internet (at least for now). The MAP can be found in the Photos

Sorry about my late entry.. just joined. The ripples on the original 70cm VSWR image are the sort of thing regularly seen in microwave waveguide return loss measurements. These RL/VSWR ripples

During Kenwood transceiver bench alignments, they specify 100dBuVEMF as the S9+20 outer marker. This equates to -1dBm. As an anecdote, during a contest with multi-transmitters, we saw around 3Volts of

If Wikipedia does not want the NanoVNA entry, please consider using the IEEE sponsored www.ethw.org history wiki. It's the perfect repository for articles, photos, sound and vision.. Being an IEEE

Early on firmware developers made "Menu Structure Maps" available. Is this, what is now missing with all the latest firmware? Is this what Chris is looking for? Richard K8CYK

Perhaps the team over at Nifty-Guides could create one. They do a ton of ham radios and other products. Eric Gildersleeve

Chris, As simple as the NanoVNA looks, there is really no quick reference on how to use it - it is a full VNA in the real sense. That is like asking for a QR card for an HP or Anritsu VNA. However,

A “Quick Reference Card” that I could print and learn with like in the field or bench. No app or PC. The Wiki How to (at the end), YouTube, tells you how but not a “Quick Reference Card”.

Unless someone mentions using with an external computer, why would someone think they were ? Peculiar logic. I used mine with the computer exactly once: to update FW and perform a battery of tests.

Try NanoVNA app by OneOfEleven. You may never go back to NanoVNA Saver. Better graphs and easier scaling, up to 4 plots on same graph, calibration works reliably and much more. You right click on

Here's a list of everything imported - excluding stuff that's imported from within NanoVNA-Saver It looks like numpy, scipy, serial and PyQT5. Source File Import statement Hardware/NanoVNA_V2.py

It would help us Elmers to know whether you are using the VNA standalone or with your PC. I never use mine standalone and always use NanoVnaSaver.

I figured so. I don’t understand the list above though. Are those just functions they do and getting PyQ5 and pyserial would catch them all? 73, Cliff, AE5ZA

yes it is. There's several dependencies - pyserial and pyQT5 are two of them. import logging import math import sys import threading from collections import OrderedDict from time import sleep,

Dino, Followed your sequence, but I already had Python3 and Pip installed so didn't do those steps. Cloned the program and tried to run the python script and it yells about no PyQT5 module. Is QT also

Does anyone know of a quick reference card (how to setup the nanovna) for doing different types of measurements, such SWR, cable length, etc.?
