Re: Useful frequency range of NanoVNA H-4?
By the way, I used the NanoVNA as an SWR meter on 1296 MHz. It worked fine. I looked at the SWR of my antennas for 222, 432, 902 and 1296 MHz. I had originally tuned these antennas with an SWR bridge and a transmitter. Now I see the adjustments are a little off for all of them except the 902 antenna. Now all I need to do is re-tune them using the NanoVNA. The NanoVNA agrees exactly with my AA-600 SWR meter for SWR across 5 to 30 MHz with my MFJ 1796 vertical antenna.

MHz that I have for a transverter. The helical filter is mounted on a pc
board with SMA input and output. I calibrated the NanoVNA for 1280 to 1320
MHz and connected the filter to it. The NanoVNA displayed s11 as I expected
(a good dip which I could adjust to 1296 MHz). However, the s21 did not
display what I expected. I expected a response that a normal bandpass
filter would have. Instead, I had pretty much a straight line for s21
across the frequency range that fluctuated with each reading.
Is the performance poor at 1296 MHz?

This is getting into the classic bike shed painting exercise - If you want to make available binaries of test versions for someone to test (not actually "releases", per se) without the matching source code, then I suppose it's "technically" a GPL violation (IANAL and all that). I think that the *intent* of GPL is satisfied by making source available for major *releases*. In theory, DiSlord could arrange a group of beta testers, set up a private distribution channel, and send binaries (without source) back and forth and not get the GPL knickers in a twist. This would be no different from a group of developers at a company all working on various pieces of a product. But why bother. Yes, I understand "thin edge", "camel's nose", "slippery slope" arguments. Ultimately, though, the question is whether *meaningful* source code releases are occurring (and I think they are). I would say that this kind of (IMNSHO) bickering is why open source has a reputation for being a PITA. Be open about what you're doing. Publish binaries for test that are useful Publish source for releases If it goes on for 6 months with only binary, and there's significant changes in functionality, with no source release - then start asking about whether the author is living up to the spirit and intent of GPL.

DiSlord and OneOfEleven thanks so much for your contributions that have moved the NanoVNA a step forward. A few bad actors always seem to mess things up for the majority.
With all the recent demands on your time, primarily from one or two sources, I figured at some point you would wonder if its worth the effort. Some people don't seem to realize you both have other lives besides your voluntary coding activities.
Again, thanks for your many contributions and helping us to better understand the capabilities of the NanoVNA.

is anyone able to implement a new feature in the nanoVNA menu?? I need
to locate the nanoVNA inside a mokup of a cubesat to take S11
measurement for a while (10 minutes, for example). I cannot use have any
cable running out from the satellite (to not disturb measurement), so I
would like to set the nanoVNA in order to take and store measurements,
for example a measurement every minute.
Is it a dream? Is there anyone able to create this feature? That could be done Piero if you have an SD card socket fitted on your NanoVNA. Does your VNA have the SD card socket fitted ?
Could add a firmware option to record the measurement onto an SD card every so often easily enough, though the problem we have with the small NanoVNA now is that we've run out of flash area to add more options/features, but for your needs a firmware could be compiled with other features disabled in order to make room.
Another option would be to enable one of the hardware serial ports in the firmware on the VNA CPU, and then attach say a cheap (HC5 as an example) serial port bluetooth module to the VNA board.
I think separating the "instrument functions" (on the nanoVNA) and the "data collection funtions" (on the Pi) is actually how you want to do it. Focus on instrument capability, not data logging. There's myriad different data logging applications, and most of them will not want "snapshot ever N seconds" - often, there will be other things that need to happen (external configuration of the unit under test).

@DisLord and @OneOfEleven
It is unfortunately significant nowadays that many users are using free software but constantly ask for new features and also complain about this and that.
You can't please everyone!
But I want to say as many of us: please stay and go ahead! You did excellent work in the last month/weeks and we ALL do have advantages from your work.
The community and also the little VNA's need people like you!
Don't let such users put you under pressure and loose the fun!
We all will be very sad if you both will leave... Don't go!

Re: Dreaming a new option for nanoVNA
David,
The writing to the SD card is every few seconds which will do nothing to prematurely wear out the device. I use an SD card in my dashcam that is written to regularly and it's been good for 3 years now
Besides, you don't put a 128gb part in the Nano, you use a small capacity card that costs $2

The option is in the "SD CARD" menu. A setting of '0' seconds disables auto
save.
You can find the NanoVNA-H firmware (and windows software to upload the
firmware) in the "Release" folder here ..
I can't do H4 firmware because I don't have a H4 to test with.
===========================
Good way to take the life out of the SD card!? But I hope you only save when
a change is detected?
Cheers,
David

@OneOfEleven and @DisLord,
You know the dynamics of this wonderful users group "nanovna users".
After thousands of posts/replies/interactions between users we already know that this group is very technical, very deep sometimes and very dynamic.
Some (new) users caught the train while it was in full speed, making the nanovna even greater than anyone suspected.
So, don't mind these users. We all know what effort and time you spent, your patience repeating many times the same things.
One of the developer's nightmares happened in this topic, but you already experienced users demanding for new features, or timelines HIHI
Please understand that you have a big community supporting you in many ways, its not because of one particular situation you should take radical actions.
I personally thank DisLord for his invaluable dedication to the nanovna, and more recently OneOfEleven that I also praise the good sense of humor :)
So, read my words as both encoragement and a request to continue your line of work: we thank you and we will back you up.

Igor, DiSlord and others post interm releases on the forums in order to have members conduct tests and provide feedback.? This is a hobby for him, not a business. DiSlord updates his GitHub repo every few weeks which is fine for everyone on the forum except maybe 2-3 members out of 6880 members! You are free to fork DiSlord's software and develop and test your own improvements and release them on the forum...so? Have patience.? ...

@Dislord: do you still consider the project open-source?
Not understand. All my code open on git you can use it.
Last stable code (96k mode and SD card support, and UI) also on github and
open.
When you distribute the 1.0.XX binaries (like here on this forum or on cqham.ru or vrtp.ru) you shall provide the source code on your github too. It does NOT matter whether those binaries are called "final" or "beta". For example - with "1.0.14" beta binary the community has to be able to build the "1.0.14 beta" out of the source code on your github. Or i must add on my github every my test option?
Yes. Otherwise one can distribute "test" or "beta" binaries for next 10years without providing source code. And the "open-source" project bites the dust. Or ... i should support code? But sorry for this need a lot of time, and this
not my main work.
Nobody can ask you to support the code, this is an open source project. HTH

Hi DiSlord
is it normal that the on / off configuration of the traces is not saved?
When I browse the menus I often have freezes with version 1.0.13 and 1.0.14. it is not systematic. This often happens with the "Version" menu
I have never seen this before with version 1.0.11

Very well expressed, and you have my 100% agreement!
I can see NO non-compliance with the GPL in the way that beta testing has been conducted via this forum, and NO need to change behaviour in any way.
PLEASE continue, guys.

Using the NanoVna-H4 with the Nano Saver I have a question about the way of calibrating.
Using the NanoVna stand alone, then after opening the Calibration menu I see the Open on top of the menu, then the Short and then the Load.
When I use the Calibration Assistant in the Nano Saver or the Calibrate Section then the order is Short, Open and Load.
Is this order essential for a good calibration, or can I use the calibration components in a random order?
