Re: automatic loading of a nanovna saver cal file?
I believe it will load Memory 0 on power on so save the calibration to # 0 and it should load it for you on power on.

I am trying to avoid doing a CAL on the nanoVNA screen as it is difficult for me to red it.
So I want to do the cal via nanpVNA aver, but on startupm nanoVNA Saver always says there is no calibration.
So I am still looking for a way to have nanoVNAA Saver automatically load a CAL file that I previously saved after doing a cal via nanoVNA Saver.

Re: Where to buy a NanoVNA H4 HW rev 4.3?
An early version of 4.2, that's probably why you do not have the
SD slot. You can solder one yourself ...
AFAIK the N variety was only made with NanoVNA V2, a different platform.
Only difference from the regular V2 is the metal case and the SMA to N
adaptors.
A few people made the same modification on their own, but it is a bit of a
hassle as you would
need to get N calibration loads ...

Looks good, not much of a change except that the new version is a few dB better from 200-280Mhz. On Tue, 11 Jan 2022 at 03:16, Stan Gammons via groups.io <buttercup11421= [email protected]> wrote: Not sure I did this right, but here is what I got.

Can you post a s2p file when the device is in an uncalibrated state, port1

Here is the image of my board and the s2p file (401 points, 5 segments,

but I do not know if that one has other changes.

It's a slot for an SD card.
Where (and when) did you get your device from?

Yes, it can when using PC and at least SAVER. Store the cal file on the PC
for later use.

It automatically loads slot 0 cal data on the most NanoVNA models. IIRC some versions of firmware can recall the last configuration used. Roger

Funds for 2022 nanovna-users group annual fee
All,
As I posted before, we have sufficient funds pledged to pay the groups.io fee for 2022.? The response, in under two days, has been overwhelming.
**Further pledges are not necessary**.
We will need to do this every year going forward, so there will be ample opportunity to contribute in the future.
Thanks to everyone who has pledged to support the group.
The next steps for collecting the pledged funds and paying the fee to groups.io will occur starting next week.
