"I think somebody should write some software (add to to Nanosaver!!!) that makes the nano work like a simple? analyzer, or a NanoVNA for dummies like me! "
This has already been done but unfortunately, it hasn't been updated since last December.
If you have any nanoVNA or NanoVNA-H, you can play with the firmware:
Last release:?
Also - if you have an IT background, NanoSaver is written in Python and is very modular - why not try you hand at creating a simple antenna analyser add-on?

GREAT QUESTION, GREAT THREAD!!
As a newbie to ALL of this (HAM, Antenna¡¯s, VNA¡¯s, analyzers...) I too have a long, STEEP slope to climb to learn any of this ¡°stuff¡±!? I have an IT background, so have a little tiny bit of ¡°technical¡± knowledge, but not nearly anything all you smart guys have!
Having said that, I bought a NanoVNA to play around with and try to learn something, and hopefully along the way learn just enough to help me setup my shack (I just ordered a radio, and researching a VHF/UHF and a HF antenna) and tune the antenna¡¯s.? So too have pondered this same question, would I have been better off just buying a cheap, simple ¡°Antenna analyzer¡±?? ? I ended up getting the nano based on it can do the same thing the analyzer does, you just have to know how.? But the ¡°how¡± part is the difficult part for a newbie like myself.
I think somebody should write some software (add to to Nanosaver!!!) that makes the nano work like a simple? analyzer, or a NanoVNA for dummies like me!? You select a menu item, ¡°Analyze Antenna¡±, it then tells you what exactly to do, you do it and click NEXT, until it has some simple results similar to an analyzer.? And I mean dumbed down to the something like this:
[START selected menu item analyze antenna]
¡°Please connect the open calibration connector and press NEXT¡±
¡°Please connect the short.....¡±
¡°Please connect your antenna¡±
¡°How long is your feedline: xxx meters¡±
¡°Enter the HAM band you would like to test:? xx? meter band¡±
[Scan done, results displayed]
¡°Your antenna is tuned to:? xxx.xxxx MHz and usable from xxx.xxxx to xxx.xxxxx in this band¡±
¡°Select next band to test: xx meter band¡±
...
...
The beauty of this would be it would be quick and easy, and it would setup all the settings and parameters required on the NanoVNA and in Nanosaver for you.
If somebody adds this to Nanosaver, I will offer to be the ¡°dummy¡± to test it!!? ;)

I bought a RigExpert AA-600 a few months ago. I got it directly from them with the Smith Chart option. It also measures L, C and R and has a TDR function. So far I have been very impressed. I have yet to explore the possibilities of the NanoVNA H4. From what I have read, I should be impressed wit it, too. We have various HP VNA's at work that cover up to 750 and 1500 MHz.

Love them both, my MFJ is still working fine (test it on a regular basis
on different loads), bought it in 1999 together with the MFJ carrying
pouch. Looking back: a good buy.

Can any of you give a reason pro or con as to why nanovna vs MfJ 259 series. I presume many are nanovna users due to the lower cost. Is there
any tradeoff that would discourage either?

Re: NanoVNA-H4 Touchscreen Completely Unresponsive
Thanks for the very quick reply Hugen! This is the link to the exact device/vendor I purchased from:
I will begin a return immediately. Thank you!

Re: NanoVNA-H4 Touchscreen Completely Unresponsive
It seems that the touch screen may be malfunctioning, please contact the dealer you purchased, we will send you the new NanoVNA-H4 through the dealer.

Re: NanoVNA-H4 Touchscreen Completely Unresponsive
Forgot to add - My firmware version is 0.5.0 so it's the latest Hugen firmware.
Would flashing a different firmware be the solution? If so, should I try flashing the latest Edy555 firmware (v0.7.1) or possibly the AA6KL ChibiOS version?
Thanks sincerely,
Dan

NanoVNA-H4 Touchscreen Completely Unresponsive
Hi all,
I recently bought a NanoVNA-H4 on Amazon. It seems to be working fine, but the touchscreen does not work at all - I've tried using my finger, the plastic pick that comes with the system, metal and plastic pens. No success.
This is not the plastic enclosure pressing on the screen issue - I have removed the enclosure and the screen still does not work.
Using the toggle switch I tried navigating to the Touchscreen Cal and Test menus but nothing happens during either of those functions. I just have to turn the unit off and back on again.
Is there anything I can do or should I return this?
Thanks,
Dan

Possibly incorrect setting of vbat_offset (old software use hardcoded value, new read not correct from config)?
Try reset it by run in console
'vbat_offset 0'
Or reset all config (it better, for solve another possible conflicts)
'clearconfig 1234'
Always on update better do reset config

Rudolf, Du musst D2 auf dem Board einl?ten. Der Prozessor bekommt ueber
diese Diode die Akkuspannung zur Auswertung. Solange die Diode fehlt,
zeigt er Akku-leer an.

what does it mean now? The battery indicator is shown, but always as red / empty. The original software had displayed correctly, unfortunately I do not know which firmware I have to load so that it works again? Sorry for my bad English.

=======================================
Rudolf,
If you have a NanoVNA without D2 installed then I believe the new firmware is smart enough not to display the battery icon. The battery level cannot be measured without D2.

Re: Test fixture question
Hi Nick,
thank you for sharing.
The last message from the PHSNA group was on December 28, 2019.
In the "Group Milestone" topic, Jim, N5IB, wrote that he wanted someone to take over the group, which they said didn't happen. (or just not visible to me) I tried to log in but no confirmation.
Thanks again for sharing the referenced material.

Dislord,
That is correct. edy555 commented that he ran into the Uint32_t limit with the screen shot he provided.
