Maybe a small animated progress bar or count-down timer could be added?

I have had the SD socket in it for a week so I was able to test.
What I have experienced is that when I want to save a screen image, it recognizes the sd card and the structure seems to hang. Or I didn't wait long enough and then you'll tell me. There was no window for what name to save. The same happens in the menu when saving .s1p under SD Card. It’s like it freezes or I should see what I don’t know because the drawing freezes and apparently nothing happens.
I hope this helps you move on.

Possibly i not correct vork vs short filenames (not test it)? as i see SD card work, answer, problem only in work vs lib or screen read.
Here support long names like at H4 (now in most cases code some except support exFat), now i hope it work

I scrounged one from an old cellphone but there are different footprints so you'll need to see if a cheap multi format card reader might also have the correct type of socket.?

Got a H4 here and I see that there is space/footprint for a mini/micro? SD.
Does anyone has a partnumber on what connector can we place there?

Ordered on June 2nd and received today (6th). Love the bigger screen compared to my 2.8 inch unit.

See this topic for more info
/g/nanovna-users/topic/nanovna_firmvare_compiled_by/73181877

For H4 version

Possible search for alternative, but select option:

microSD? Memory Card "connector&Ejector"

option for easy insert and remove card (use Push In，Roll out option)

That looks great!

Hello everyone,

I am the originator and co-owner of [email protected]. I can shed some light on occasional posts of this type (not necessarily this post, but it seems like a good reason to jump in, along with noting our first year of service!) ---

About 2 months ago, the other Dave (our co-owner) suggested we change the group's new user policy to allow immediate join, but have "new user moderated", meaning that a new person can immediately join the group without delay (allowing reading messages the file/wiki archives), but may not freely post until their first post has been manually validated by either of the Daves (the post will be held and both of us will receive a notification e-mail when this happens). This was done to streamline the administrative workload (our group is now well over 6000 members, almost exactly a year since it was started 6/3/2019), as the number of first-post events is smaller than the number of join events (the change immediately had the desired effect for the two Daves). Usually the first post moderation clearance happens within a few hours at most, but occasionally a little longer as both of us are occasionally asleep at the same time or otherwise unavailable (we're both in US, in two separate time zones.)

So, if you have joined the group at some point, and make your first-ever post (a new message post or a reply post), and don't see your first post appear in your e-mail (if you are on single message delivery), the next digest e-mail (there are usually several per day), or on the group's web interface messages area, it's awaiting new user moderation clearance, and once cleared, your posts will appear as quickly as system conditions permit.

By the way, neither of the new user mechanisms (manually approve join request, but allow immediate posting, or automatically approve join requests, but moderate first posting) are foolproof at preventing spam (which is why groups.io doesn't permit a group to exist which has neither of these mechanisms in place) (we've been spammed a couple of times, the best way to handle that is to immediately flag the post as offensive, which will notify the two Daves who will ban the user and usually clean up the archives, although we can't prevent the spam and any follow-up posts from appearing in e-mail deliveries) without resorting to even more time/delay intensive moderation processes, so overall the current seems to be a reasonable balance between administrative workload and preserving the SNR (integrity) of the group.

Thanks again for your interest and participation in nanovna-users on groups.io!

73, Dave

Great, thanks!

I'll give it a try.

If you have installed SD card slot on NanoVNA it you can try check work

Work as on h4 version vs some limits (not supported exFat filesystem, and not use long filenames, limits from less flash size)

Enable console and made some screenshots and try save s1p or s2p file

I dunno, it was kind of fun..

As i'm using the NanoVNA-H essentially for HAM bands, i tried to use a 3 outputs splitter (1.6 - 160MHz, 350 - 500MHz and 850 - 1300MHz).

I've done one 2 ports calibration for each output.

The measured spectrum for each output is not too bad (far better compared to direct VNA output) and SWR measurements on HF, 6m, 2m , 70cm and 23cm seem to be corrects. I tried to use a little Tera Term macro for direct frequency setting and that's ok too. (By choosing the correct splitter's output!)

The new user over my head posting gave me what I was looking for. A test fixture for multiple uses. A couple will be on order shortly.

FYI, I just noticed that Alan, W2AEW, on his YouTube channel just posted a great new video on this topic explaining some of these terms I listed. Many thanks Alan if you are on this group. Also Alan works for Tektronix now, and I did for 11 years.

Use 20Log for voltage ratios and 10Log for power ratios.

This video of mine might help:
