Is there any software written that runs on a Mac and connects to the nanoVNA? All I seem to find is Windows only. 73, Cliff, AE5ZA

Thanks for the confirmation, Dragan. And yes, the answers were all for the NanoVNA rather than Saver. Chuck

It seems that everyone is missing the SAVER part. Anyway there is no such feature in the NanoVNA Saver.

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. 73, Cliff, AE5ZA

Roger - 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

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

Looks good, not much of a change except that the new version is a few dB better from 200-280Mhz. [email protected]> wrote:

Thank you. Bought from R&L on 4/9/2020 and since updated to V 1.0.39; Kernel 4.0.0. STM32F303xC I'm interested in the N-connector variant and wonder are they really more robust? No complaints with

Not sure I did this right, but here is what I got. 73 Stan KM4HQE

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

What is Card1 at top? I do not have that in my variant. HW

Did you notice any change in the performance (presuming that you have both versions)? [email protected]> wrote:

Thanks, as expected, small changes in the layout compared to 4.2.1 that I have. Can you post a s2p file when the device is in an uncalibrated state, port1 terminated port2 left open? Here is the image

Yes, it can when using PC and at least SAVER. Store the cal file on the PC for later use. Dave - W?LEV -- *Dave - W?LEV* *Just Let Darwin Work*

Here is how the PCB layout changed between 4.2 and 4.3 in the power supply area. Roger

There were quite a few changes to the voltage regulators from 4.2 to 4.3. Roger

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

Can this be done? I have sometimes forgotten to load the file. Chuck

Here's a pic of one I got from R&L recently 73 Stan KM4HQE

Yes no problem at all I will get some pictures, this is the V4.3 with SI5351, There is another version which is has a MS5351M which is V4.3-MS, but I do not know if that one has other changes.
