    What is woefully missing, but very much needed, is a user friendly guide for NanoVNA.
    It must have:

    1.) Step by step instructions
    2.) Photos of each step
    3.) Clear layman's language
    4.) Be geared toward use for antenna analyzing

    It must NOT have:



    1.) A historical review of development
    2.) Geek/nerd speak
    3.) Useless ramblings about lab/shack layout
    4.) Scientific calculations
    5.) be a Youtube (I like my movies action/adventure genre.)

    If anyone has this, knows where it exists, or can do this and post or share it, I believe the likely 98% of us who've bought one and are angry with the hickory nut shell complexity of what should be straightforward would greatly appreciate it.

    And please don't tell me how dumb I am. I already know it.

    After all, all I want to do is calibrate it and analyze antenna systems. . .

    i agree on skipping history and scientific calculations. Drop the $100. Words and college edgumacted words too

    Not knocking all that. It's simply that it is useless in terms of which menu item do you push in what sequence to calibrate and sweep for antenna analysis.

    Have you seen the epub manual on Amazon? It's under $3. I haven't bought it yet, but reviews says it's good. I don't know if it's super duper technical, though.

    After flipping thru it, I recommend purchasing the download. For $3, it's an excellent resource.

    I'll take a look. Thanks. But at the moment, this thing is too light to make a decent paper weight.

    The book concentrates on the NanoVNA itself. It's well written and organized. It discusses the origins of the device. It describes the different versions, how to check and upgrade firmware and various mods and hacks. The different measuring techniques are well described. I'm surprised it only cost $3.

    I'm thinking of buying the other model that has 23cm. I wish I would have researched more before grabbing this one.

    I don't work anything higher than 70cm. But there may come a day...

    I read where this particular units accuracy is optimized up to 340MHz. After that, I suppose it starts to fall off. Once I create a range and calbrate, I recheck it with the calibration standards and observe the Smith Chart to be sure it looks like a good calibration. So far, this device holds it's own against lab grade VNA's.

    With the NanoVNA's rapid popularity and the developers motivation, I'm sure were going to see much better units. Might cost a little more, but will be worth it. I imagine the big makers are watching this device very carefully. Limitless marketplace for something like this. The Facebook and IO groups are buzzing with interest.

    I think I likely am unable to appreciate its potential.
    Nevertheless, I would like to use it as an antenna analyzer.

    Have you watch the various YouTube videos? There are many. I've learned a lot just from the videos. The Amazon book takes all the various Chinesium language documentation and translates it into a readable form. I kept scratching my head trying to decipher it.
