Thanks for the notes on the Python VM and getting nanoVNA-Saver to run on
Linux.
I just installed Linux Mint 20 (which is totally different from Ubuntu)
and revisited the Python VM instructions from Nick G3VNC.
I found I could make those instructions work if I replaced every mention of
"python3.7"
with the words "python3.8", I get lost every time I try to do it the
second time or just the next day.
And I have never gotten the shortcut script to work to make it quicker,
WELL your version is easy to read, I may have a chance, SO thank you very
much!
I will try and give it a try.

I dropped some notes in the file section of this group, at
/g/nanovna-users/files/Nano%20VNA%20Saver. The file is
*nanoVNA-H4 software support under Ubuntu.pdf*
(
/g/nanovna-users/files/Nano%20VNA%20Saver/nanoVNA-H4%20software%20support%20under%20Ubuntu.pdf
).
The approach described works with a nanoVNA-H4, and hopefully a
nanoVNA-H. Essentially, a Python VM (virtual machine) is set up so that
NanoVNA-Saver runs in its own isolated Python environment, avoiding
interference to/from the rest of the Python needed to keep the OS
running sweetly. A script is used to enter the Python VM, and then to
exit the VM after NanoVNA-Saver itself exits. Then all is well.
HTH, 73, Stay Safe,
Robin, G8DQX
PS: It took me a while to find the answers, and one learnt about Python
VMs.

And I'm sorry if any messages seem strange. Use electronic translator.

I tested it now and realized that the clock stops working when turned off.
I use crystal so that the time is always updated even with the nanoVNA off.
Take it easy, do it when possible and thank you for your work.

Screenprint (problem), S1P and S2P ok for me.

Try this one, don't let go of touching the bottom of the screen until it shows
a message on screen, it should be work 100% of the time ..
Thank you for your work. I will test now !!

Firmware for NanoVNA H4 with L/C Match?
Has anyone compiled a version of firmware for the VNA H4 that has the L/C Match built in?
Thanks,

Vaclav,
it sounds as if you need a local mentor to help you with Linux.
For the terminal, you may find this helpful:
Good luck, HTH, Stay Safe,

Robin, I am still learning how to navigate this group.
Perhaps some day I figure out what "messages" are for ,besides a "pointer" to other resource.
Was not aware the files are sort-off manuals.
I am not a Python fan and when I first used it - it bombed my Linux "terminal" application,
I have not completely "recovered" from the loss of "terminal" , the "substitute " ~ tilda - is driving me crazy.
I'll take a look at Python VM , I'll do just about anything to get back my "terminal".
I just "love" Linux's "BTW - you need to enable "dialout"...
Installed and running 'chirp" and it may have another "BTW..." changing the/dev/ rfcommx each time it is loaded /executed.
Update
I have sort-off / partially solved the "custom icon" - Linux application "gnome launcher" is working. but I need to figure out how to link several CLI commands.

I also think there is no need to rush, install the SD CARD slot, and calmly check. Good luck!

I calibrated the touchscreen even more accurately, it turns out to take a screenshot of 20 times. I think I understand the reason, this is a long processing time for clicking on the touchscreen, in your firmware, pressing as if with a delay, maybe this affects.
In dislord firmware, out of 20 times, I manage to take 17-19 screenshots. It seems to me that delay is a matter of filtering.

I need more details.
When you touch the very bottom of the screen, does the menu pop up or not ? .. hopefully it doesn't pop up
I've ordered some SD card PCB sockets so that I can test it properly on the little NanoVNA-H.

Somewhere else a small mistake.

oh I see, OK.
Added the touch bottom of screen to save screen to SD card, try this ..

Re: NanoVNA firmware user interface mod

In DiSlord firmware, the screenshot works if you click on the bottom of the screen. In the firmware from OneOfEleven, it is not possible to take a screenshot.

The save function s1p, s2p in the menu works.
On my firmware (BW string is gray), i think need recalibrate touch. I change touch process function for better measure touch position See this post /g/nanovna-users/message/14861

that is a good point... port permission is key

Wait a minute, that's not the firmware I'm working on DMR ??

The newly added LC matching is actually very useful.
Here's one of those little super dooper pre-amps that you can buy three for just 8 UK pounds (SPF5189Z 0.5dB-N.F 22dBm 1dB-Comp 50MHz to a few GHZ). They work wonderfully without any matching down below 30MHz up to GHz's, but I guess it helps to optimise things.
