When you say settings, are you talking about calibrations?

Thank you, John. Never thought about simply overwriting previous settings. Your suggestion works great. Many thanks.

73, Bob, KN4HH

Using NanoVna V2 SAA-2N fw 1.1.00, and just starting to try to use VNA-View 1.1 on Linux computer. Never used this software before.

Is there a way to save a calibration that I did with the nanovna not attached to the computer? For example, I am outside and do a calibration and measurement. I bring the nanovna inside later in order to save and examine that calibration and measurement on the computer. I am not seeing a way to do that. When I invoke VNA-View it (and instructions I've seen) seems to want to calibrate using the computer interface, and I don't see a way to tell it to use what is already on the device.

The program does recognize the device. But does it recognize saved calibrations and measurements that were made when the device was not attached to the computer?

Thanks,
Keith

Bob,
I am a new VNA user also and I'm sure that I'll be corrected if wrong..... I assume that when you overwrite you in effect delete any previous entry that you have saved as there are limited memories for this use.
Enjoy,

I am a new user of an H4. I understand how to create and recall settings for measurements (swr, reactance, etc.) I created several sets of measurements while learning the unit. I have been unable to find a way to delete my practice settings.

Thanks for any assistance.

No, you have it wrong. If you can't get an answer on Facebook (correct or otherwise) it doesn't exist.

And this is why I'm not so wild about videos as "reference material". A
video is great for a demonstration of how to do something. I just
disassembled and regreased my Kitchenaid mixer, and frankly, seeing
someone else do it made it a lot easier. The written instructions say
something like "apply sufficient grease" - seeing someone do it tells
you a lot more. But a video to tell me how to install software, entirely
from the command line? 1 page of cut and paste from the screen would
have met the need, I didn't need to hear someone talking about "now I'm
entering the sudo pip install numpy command" and watching them type on
the screen.

The firmware commands (most of them) are documented in a pdf file called

NanoVNA_Console_Commands_Dec 9-19.pdf which can be found on the groups.io nanovna website.
/g/nanovna-users/files


Generally, the firmware will respond to a help command to give a list of them all.

Yes there is in the Files section of this group.

But that probably does not interests majority of users....

Yes count me as one of those not interested.

It appears the formatting foe is JUNO, itself, i.e., composing emails on the website and sending from there.

This is composed on the groups website.

To repeat:

My comptriots and Elmers,

The Author of the formatting debacle, though into the silver sneakers domain, has yet to contrract, or develop, any chronic diseases and/or disorders. Id say more victim of cruel fate, when need to be understood was maximum.

If you'd like to be privy to my secrets for a health-span, matching your life-span, 1, crimp-on, PL-259 or a picture of the first distaff Ham, will bring you as close to immortality, as humanly possible.

I cant begin to fathom what happened or where. All I can say is JUNO is always replete with werird characters but they do not despoil formatting into "to hell with this".



I apologize, by proxy, for whom or what was responsible.

What Jim pointed out just happened to an email I sent out using Yahoo.? I started with a web link and the email got all run together ?

"Cannot", of course.

On other lists, I've found it sometimes due to the specific mail client and in one case has to do with creating HTML mail where the line breaks were <br> not <p> and somewhere along the line, the <br> get stripped out.
In another case it was where the lines were being composed on a very skinny window, and the "end of line" happened to line up with the edge of the window (along with other "as displayed" breaks that weren't sent), so the person composing the mail didn't realize there were no line breaks - it looked ok on their end. They had inserted line breaks to separate paragraphs, but those got stripped out as superfluous for some reason.
